Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by GAAP for annual financial statements. We have omitted certain footnote disclosures that would substantially duplicate the disclosures in our Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report on Form 10-K”), unless the information contained in those disclosures materially changed or is required by GAAP. We have filed Exhibit 99.1 to this Quarterly Report on 10-Q to recast certain prior years’ financial information and related disclosures to reflect the changes to our reportable segments beginning in the first quarter of 2023 discussed above, as well as the impact of the adoption of a new accounting standard related to the accounting for long-duration insurance contracts, which we adopted on January 1, 2023, using a modified retrospective transition method as of January 1, 2021. The recast financial information and related disclosures set forth in Exhibit 99.1 to this Quarterly Report on Form 10-Q present such financial information and related disclosures in these items as they would have appeared had we changed our reportable segments and adopted the new accounting standard prior to January 1, 2023 and do not reflect events or developments that may have occurred subsequent to the filing of our 2022 Annual Report on Form 10-K. In the opinion of management, all adjustments, including normal recurring adjustments, necessary for a fair statement of the consolidated financial statements as of and for the three and nine months ended September 30, 2023 and 2022 have been recorded. The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2023, or any other period. The seasonal nature of portions of our health care and related benefits business, as well as competitive and other market conditions, may cause full-year results to differ from estimates based upon our interim results of operations. These unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements as of and for the year ended December 31, 2022 included in Exhibit 99.1 to this Quarterly Report on Form 10-Q.	Basis of Presentation: The accompanying consolidated financial statements include the accounts of Elevance Health and its subsidiaries and have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). All significant intercompany accounts and transactions have been eliminated in consolidation. The accompanying consolidated financial statements and the notes to the consolidated financial statements have been recast and are presented as they would have appeared had we changed our reportable segments, discussed in Note 20, and adopted the new accounting standard, discussed in this Note 2 below, prior to January 1, 2023.
Foreign Currency	Certain of our subsidiaries operate outside of the United States and have functional currencies other than the U.S. dollar (“USD”). We translate the assets and liabilities of those subsidiaries to USD using the exchange rate in effect at the end of the period. We translate the revenues and expenses of those subsidiaries to USD using the average exchange rates in effect during the period. The net effect of these translation adjustments is included in “Foreign currency translation adjustments” in our consolidated statements of comprehensive income.

The net effect of these translation adjustments is included in “Foreign currency translation adjustments” in our consolidated statements of comprehensive income.
Cash and Cash Equivalents	Cash and Cash Equivalents: We control a number of bank accounts that are used exclusively to hold customer funds for the administration of customer benefits, and we have cash and cash equivalents on deposit to meet certain regulatory requirements. These amounts totaled $300 and $258 at September 30, 2023 and December 31, 2022, respectively, and are included in the cash and cash equivalents line on our consolidated balance sheets.	Cash and Cash Equivalents: Cash and cash equivalents includes available cash and all highly liquid investments with maturities of three months or less when purchased. We control a number of bank accounts that are used exclusively to hold customer funds for the administration of customer benefits, and we have cash and cash equivalents on deposit to meet certain regulatory requirements. These amounts totaled $258 and $173 at December 31, 2022 and 2021, respectively, and are included in the cash and cash equivalents line on our consolidated balance sheets.
Investment, Policy	Investments: We classify fixed maturity securities in our investment portfolio as “available-for-sale” and report those securities at fair value. Certain fixed maturity securities are available to support current operations and, accordingly, we classify such investments as current assets without regard to their contractual maturity. Investments used to satisfy contractual, regulatory or other requirements are classified as long-term, without regard to contractual maturity. If a fixed maturity security is in an unrealized loss position and we have the intent to sell the fixed maturity security, or it is more likely than not that we will have to sell the fixed maturity security before recovery of its amortized cost basis, we write down the fixed maturity security’s cost basis to fair value and record an impairment loss in our consolidated statements of income. For impaired fixed maturity securities that we do not intend to sell or if it is more likely than not that we will not have to sell such securities, but we expect that we will not fully recover the amortized cost basis, we recognize the credit component of the impairment as an allowance for credit loss in our consolidated balance sheets and record an impairment loss in our consolidated statements of income. The non-credit component of the impairment is recognized in accumulated other comprehensive loss. Furthermore, unrealized losses entirely caused by non-credit-related factors related to fixed maturity securities for which we expect to fully recover the amortized cost basis continue to be recognized in accumulated other comprehensive loss. The credit component of an impairment is determined primarily by comparing the net present value of projected future cash flows with the amortized cost basis of the fixed maturity security. The net present value is calculated by discounting our best estimate of projected future cash flows at the effective interest rate implicit in the fixed maturity security at the date of purchase. For mortgage-backed and asset-backed securities, cash flow estimates are based on assumptions regarding the underlying collateral, including prepayment speeds, vintage, type of underlying asset, geographic concentrations, default rates, recoveries and changes in value. For all other securities, cash flow estimates are driven by assumptions regarding probability of default, including changes in credit ratings and estimates regarding timing and amount of recoveries associated with a default. For asset-backed securities included in fixed maturity securities, we recognize income using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The net investment in the securities is adjusted to the amount that would have existed had the new effective yield been applied since the purchase date of the securities. Such adjustments are reported within net investment income. The changes in fair value of our marketable equity securities are recognized in our results of operations within net gains and losses on financial instruments. Certain marketable equity securities are held to satisfy contractual obligations and are reported under the caption “Other invested assets” in our consolidated balance sheets. We have corporate-owned life insurance policies on certain participants in our deferred compensation plans and other members of management. The cash surrender value of the corporate-owned life insurance policies is reported under the caption “Other invested assets” in our consolidated balance sheets. We use the equity method of accounting for investments in companies in which our ownership interest may enable us to influence the operating or financial decisions of the investee company. Our proportionate share of equity in net income of these unconsolidated affiliates is reported within net investment income. The equity method investments are reported under the caption “Other invested assets” in our consolidated balance sheets. Investment income is recorded when earned. All securities sold resulting in investment gains and losses are recorded on the trade date. Realized gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold. We participate in securities lending programs whereby marketable securities in our investment portfolio are transferred to independent brokers or dealers in exchange for cash and securities collateral. We recognize the collateral as an asset, which is reported under the caption “Other current assets” on our consolidated balance sheets, and we record a corresponding liability for the obligation to return the collateral to the borrower, which is reported under the caption “Other current liabilities.” The securities on loan are reported in the applicable investment category on our consolidated balance sheets. Unrealized gains or losses on securities lending collateral are included in accumulated other comprehensive loss as a separate component of shareholders’ equity. The market value of loaned securities and that of the collateral pledged can fluctuate in non-synchronized fashions. To the extent the loaned securities’ value appreciates faster or depreciates slower than the value of the collateral pledged, we are exposed to the risk of the shortfall. As a primary mitigating mechanism, the loaned securities and collateral pledged are marked to market on a daily basis and the shortfall, if any, is collected accordingly. Secondarily, the collateral level is set at 102% of the value of the loaned securities, which provides a cushion before any shortfall arises. The investment of the cash collateral is subject to market risk, which is managed by limiting the investments to higher quality and shorter duration instruments.

All securities sold resulting in investment realized gains and losses are recorded on the trade date. Realized gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold. We participate in securities lending programs whereby marketable securities in our investment portfolio are transferred to independent brokers or dealers in exchange for cash and securities collateral. Under Financial Accounting Standards Board (“FASB”) guidance related to accounting for transfers and servicing of financial assets and extinguishments of liabilities, we recognize the collateral as an asset, which is reported in other current assets on our consolidated balance sheets, and we record a corresponding liability for the obligation to return the collateral to the borrower, which is reported in other current liabilities. The securities on loan are reported in the applicable investment category on our consolidated balance sheets. Unrealized gains or losses on securities lending collateral are included in accumulated other comprehensive income as a separate component of shareholders’ equity. The market value of loaned securities and that of the collateral pledged can fluctuate in non-synchronized fashions. To the extent the loaned securities’ value appreciates faster or depreciates slower than the value of the collateral pledged, we are exposed to the risk of the shortfall. As a primary mitigating mechanism, the loaned securities and collateral pledged are marked to market on a daily basis and the shortfall, if any, is collected accordingly. Secondarily, the collateral level is set at 102% of the value of the loaned securities, which provides a cushion before any shortfall arises. The investment of the cash collateral is subject to market risk, which is managed by limiting the investments to higher quality and shorter duration instruments.
Receivable	Receivables: Receivables are reported net of amounts for expected credit losses. The allowance for doubtful accounts is based on historical collection trends, future forecasts and our judgment regarding the ability to collect specific accounts. Premium receivables include the uncollected amounts from employer risk-based groups, individuals and government programs for insurance services. Premium receivables are reported net of an allowance for doubtful accounts of $188 and $152 at September 30, 2023 and December 31, 2022, respectively. Self-funded receivables include administrative fees, claims and other amounts due from fee-based customers for administrative services. Self-funded receivables are reported net of an allowance for doubtful accounts of $93 and $68 at September 30, 2023 and December 31, 2022, respectively. Other receivables include pharmacy rebates, provider advances, claims recoveries, reinsurance receivables, proceeds due from brokers on investment trades, accrued investment income and other miscellaneous amounts due to us. These receivables are reported net of an allowance for doubtful accounts of $875 and $744 at September 30, 2023 and December 31, 2022, respectively.

Self-funded receivables include administrative fees, claims and other amounts due from fee-based customers. Self-funded receivables are reported net of an allowance for doubtful accounts of $68 and $50 at December 31, 2022 and 2021, respectively. Other receivables include pharmacy rebates, provider advances, claims recoveries, reinsurance receivables, proceeds due from brokers on investment trades, accrued investment income and other miscellaneous amounts due to us. These receivables are reported net of an allowance for doubtful accounts of $744 and $648 at December 31, 2022 and 2021, respectively.
Revenue Recognition	Revenue Recognition: For our non-risk-based contracts, we had no material contract assets, contract liabilities or deferred contract costs recorded on our consolidated balance sheet at September 30, 2023. For the three and nine months ended September 30, 2023 and 2022, revenue recognized from performance obligations related to prior periods, such as changes in transaction price, were not material. For contracts that have an original, expected duration of greater than one year, revenue expected to be recognized in future periods related to unfulfilled contractual performance obligations and contracts with variable consideration related to undelivered performance obligations is not material.	Revenue Recognition: Premiums for risk-based contracts are recognized as revenue over the period insurance coverage is provided, and, if applicable, net of amounts recognized for MLR rebates, risk adjustment, reinsurance and risk corridor under contractual premium stabilization arrangements, the ACA or other regulatory requirements. Premiums may also include performance incentives and penalties, which are recognized based on contractual terms. We estimate amounts receivable and payable under these contractual terms, and to the extent that such estimated amounts vary from the final amounts paid, the adjustments are included in earnings in the period of final settlement. Premium payments from contracted government agencies are based on eligibility lists produced by the government agencies. Premiums related to the unexpired contractual coverage periods are reflected in the accompanying consolidated balance sheets as unearned income. Premiums include revenue adjustments for retrospectively rated contracts where revenue is based on the estimated loss experience of the contract. Premium rates for certain lines of business are subject to approval by the Department of Insurance of each respective state. Additionally, delays in annual premium rate changes from contracted government agencies require that we defer the recognition of any increases to the period in which the premium rates become final. The value of the impact can be significant in the period in which it is recognized depending on the magnitude of the premium rate increase, the membership to which it applies and the length of the delay between the effective date of the rate increase and the final contract date. Premium rate decreases are recognized in the period the change in premium rate becomes effective and the change in the rate is known, which may be prior to the period when the contract amendment affecting the rate is finalized. Service fees include revenue from certain group contracts that provide for the group to be at risk for all, or with supplemental insurance arrangements, a portion, of their claims experience. We charge these fee-based groups an administrative fee, which is based on the number of members in a group and the group’s claim experience. In addition, service fees include amounts received for the administration of Medicare, certain other government programs, and administrative services arrangements of our Carelon (Diversified Business Group) subsidiaries, now known as Carelon. Generally, these fee-based arrangements include services which constitute a single suite of services provided and for which consideration is based upon an agreed-upon rate, regardless of the amount of services provided in a given period. As with premiums, these fee-based arrangements may include terms with retroactive rate or membership adjustments, performance incentives and penalties, each of which is a form of variable consideration within the transaction price. As such, these fee-based arrangements contain a single performance obligation that constitutes a series, and revenue is recognized over time as the services are performed. All benefit payments under these programs are excluded from benefit expense. The determination of whether services are distinct performance obligations that should be accounted for separately or combined as one unit of accounting may require significant judgment. The estimation of variable consideration to be recognized requires significant judgment in the determination of the level of achievement of performance incentives, service level achievements subject to performance penalties, and the completion level of tasks subject to implementation fees. Product revenue includes revenue for services performed by CarelonRx for unaffiliated pharmacy customers. Unaffiliated pharmacy customers include our fee-based groups that have contracted with CarelonRx for pharmacy services and third-party health plans. Product revenues and costs of goods sold for our affiliated health plans are eliminated in consolidation. Product revenue for pharmacy services is recognized using the gross method at the negotiated contract price when CarelonRx has concluded that it is the principal and it controls the services before prescription drugs are transferred to the customer. CarelonRx determined it is the principal due to its contractual rights to design and develop a listing of prescription drugs offered to the customer (formulary management); its control over establishing the pharmacy network available to the customer to have its prescription fulfilled (network management); and its discretion over establishing the pricing for prescription drugs. Overall, control over these activities indicate CarelonRx is primarily responsible for fulfilling the promise to provide pharmacy services. Product revenue includes ingredient costs (net of any rebates or discounts), including any co-payments made by or on behalf of the customer, and administrative fees. CarelonRx recognizes revenue when control of the prescription drugs is transferred to customers, in an amount it expects to be entitled to in exchange for the products or services provided. For our non-risk-based contracts, we had no material contract assets, contract liabilities or deferred contract costs recorded on our consolidated balance sheet at December 31, 2022. Revenue recognized in 2022 and 2021 from performance obligations related to prior years, such as due to changes in transaction price, was not material. For contracts that have an original expected duration of greater than one year, revenue expected to be recognized in future periods related to unfulfilled contractual performance obligations and contracts with variable consideration related to undelivered performance obligations is not material.
New Accounting Pronouncements	Recently Adopted Accounting Guidance: In November 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2020-11, Financial Services—Insurance (Topic 944): Effective Date and Early Application (“ASU 2020-11”). The amendments in ASU 2020-11 change the effective date and early application of Accounting Standards Update No. 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, which was issued in November 2018. The amendments in ASU 2020-11 extended the original effective date by one year, and now the amendments are required for our interim and annual reporting periods beginning after December 15, 2022. This standard requires us to review cash flow assumptions for our long-duration insurance contracts at least annually and recognize the effect of changes in future cash flow assumptions in net income. This standard also requires us to update discount rate assumptions quarterly and recognize the effect of changes in these assumptions in other comprehensive income. The rate used to discount our reserves for future policy benefits will be based on an estimate of the yield for an upper-medium grade fixed-income instrument with a duration profile matching that of our liabilities. In addition, this standard changes the amortization method for deferred acquisition costs. We adopted these amendments on January 1, 2023, using the modified retrospective transition method for changes to the liability for future policy benefits and deferred acquisition costs as of the transition date, January 1, 2021. While the adoption did not have an overall material impact, our prior period financial statements presented in this Form 10-Q have been restated to reflect the impacts of our adoption as required by the new standard. Recent Accounting Guidance Not Yet Adopted: In August 2023, the FASB issued Accounting Standards Update No. 2023-05, Business Combinations—Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement (“ASU 2023-05”). ASU 2023-05 clarifies existing guidance to reduce diversity in practice and is requiring a joint venture to recognize and initially measure its assets and liabilities using a new basis of accounting, at fair value, upon formation. These amendments are effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. We do not believe the adoption of ASU 2023-05 will have a material impact on our consolidated financial statements and disclosures. There were no other new accounting pronouncements that were issued or became effective since December 31, 2022 that had, or are expected to have, a material impact on our consolidated financial position, results of operations or cash flows.	Recently Adopted Accounting Guidance: In January 2021, the FASB issued Accounting Standards Update No. 2021-01, Reference Rate Reform (Topic 848) (“ASU 2021-01”). The amendments in ASU 2021-01 provide optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of the reference rate reform. The provisions must be applied at a Topic, Subtopic, or Industry Subtopic level for all transactions other than derivatives, which may be applied at a hedging relationship level. We adopted ASU 2021-01 on January 7, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows. In October 2020, the FASB issued Accounting Standards Update No. 2020-08, Codification Improvements to Subtopic 310-20, Receivables—Nonrefundable Fees and Other Costs (“ASU 2020-08”). The amendments in ASU 2020-08 clarify when an entity should assess whether a callable debt security is within the scope of accounting guidance, which impacts the amortization period for nonrefundable fees and other costs. ASU 2020-08 became effective for interim and annual reporting periods beginning after December 15, 2020. The amendments were applied on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. We adopted ASU 2020-08 on January 1, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows. In August 2020, the FASB issued Accounting Standards Update No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). The amendments eliminate two of the three accounting models that require separate accounting for convertible features of debt securities, simplify the contract settlement assessment for equity classification, require the use of the if-converted method for all convertible instruments in the diluted earnings per share calculation and expand disclosure requirements. The amendments became effective for our annual and interim reporting periods beginning after December 15, 2021. We adopted ASU 2020-06 on January 1, 2022 using the modified retrospective transition method, which resulted in an increase to our reported debt outstanding of $31, a decrease to our deferred tax liabilities of $8, and a corresponding cumulative-effect reduction to our opening retained earnings of $23, eliminating the bifurcation of the embedded conversion option; these amounts were not material to our overall consolidated financial position. The adoption of ASU 2020-06 did not have an impact on our results of operations or our consolidated cash flows. Use of the if-converted method did not have an impact on our overall earnings per share calculation. In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). The amendments in ASU 2019-12 remove certain exceptions to the general principles in Accounting Standards Codification Topic 740. The amendments also clarify and amend existing guidance to improve consistent application. The amendments became effective for our annual reporting periods beginning after December 15, 2020. The transition method (retrospective, modified retrospective, or prospective basis) related to the amendments depends on the applicable guidance, and all amendments for which there is no transition guidance specified are to be applied on a prospective basis. We adopted ASU 2019-12 on January 1, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows. In November 2020, the FASB issued Accounting Standards Update No. 2020-11, Financial Services—Insurance (Topic 944): Effective Date and Early Application (“ASU 2020-11”). The amendments in ASU 2020-11 make changes to the effective date and early application of Accounting Standards Update No. 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts (“ASU 2018-12”), which was issued in November 2018. The amendments in ASU 2020-11 extended the original effective date by one year, with the amendments required for our interim and annual reporting periods beginning after December 15, 2022. This standard requires the Company to review cash flow assumptions for its long-duration insurance contracts at least annually and recognize the effect of changes in future cash flow assumptions in net income. This standard also requires the Company to update discount rate assumptions quarterly and recognize the effect of changes in these assumptions in other comprehensive income. The rate used to discount the Company’s reserves for future policy benefits will be based on an estimate of the yield for an upper-medium grade fixed-income instrument with a duration profile matching that of the Company’s liabilities. In addition, this standard changes the amortization method for deferred acquisition costs. The Company adopted the new standard on January 1, 2023, using the modified retrospective transition method for changes to the liability for future policy benefits and deferred acquisition costs as of the earliest period presented, January 1, 2021. As a result of applying the long-duration standard using the modified retrospective method, adjustments of $(131), $54 and $0, respectively, were made to shareholders’ net income for the years ended December 31, 2022, 2021 and 2020, which include adjustments to benefit expense of $155, $(74) and $0, respectively. In addition, the following balance sheet adjustments were made at years ended December 31, 2022 and 2021: $(17) and $(4), respectively, to total assets; $47 and $(39), respectively, to total liabilities; $13 and $(19), respectively, to accumulated other comprehensive loss; and $(64) and $35, respectively to shareholders’ equity and total equity. The adoption did not have a material impact on our consolidated financial position, results of operations, cash flows, or related disclosures. There were no other new accounting pronouncements that were issued or became effective during the year ended December 31, 2022 that had, or are expected to have, a material impact on our financial position, results of operations, cash flows or financial statement disclosures.

Basis of Presentation: The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by GAAP for annual financial statements. We have omitted certain footnote disclosures that would substantially duplicate the disclosures in our Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report on Form 10-K”), unless the information contained in those disclosures materially changed or is required by GAAP. We have filed Exhibit 99.1 to this Quarterly Report on 10-Q to recast certain prior years’ financial information and related disclosures to reflect the changes to our reportable segments beginning in the first quarter of 2023 discussed above, as well as the impact of the adoption of a new accounting standard related to the accounting for long-duration insurance contracts, which we adopted on January 1, 2023, using a modified retrospective transition method as of January 1, 2021. The recast financial information and related disclosures set forth in Exhibit 99.1 to this Quarterly Report on Form 10-Q present such financial information and related disclosures in these items as they would have appeared had we changed our reportable segments and adopted the new accounting standard prior to January 1, 2023 and do not reflect events or developments that may have occurred subsequent to the filing of our 2022 Annual Report on Form 10-K.

In the opinion of management, all adjustments, including normal recurring adjustments, necessary for a fair statement of the consolidated financial statements as of and for the three and nine months ended September 30, 2023 and 2022 have been recorded. The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2023, or any other period. The seasonal nature of portions of our health care and related benefits business, as well as competitive and other market conditions, may cause full-year results to differ from estimates based upon our interim results of operations. These unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements as of and for the year ended December 31, 2022 included in Exhibit 99.1 to this Quarterly Report on Form 10-Q.

Basis of Presentation: The accompanying consolidated financial statements include the accounts of Elevance Health and its subsidiaries and have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). All significant intercompany accounts and transactions have been eliminated in consolidation.

The accompanying consolidated financial statements and the notes to the consolidated financial statements have been recast and are presented as they would have appeared had we changed our reportable segments, discussed in Note 20, and adopted the new accounting standard, discussed in this Note 2 below, prior to January 1, 2023.

Foreign Currency

Certain of our subsidiaries operate outside of the United States and have functional currencies other than the U.S. dollar (“USD”). We translate the assets and liabilities of those subsidiaries to USD using the exchange rate in effect at the end of the period. We translate the revenues and expenses of those subsidiaries to USD using the average exchange rates in effect during the period. The net effect of these translation adjustments is included in “Foreign currency translation adjustments” in our consolidated statements of comprehensive income.

Cash and Cash Equivalents

Cash and Cash Equivalents: We control a number of bank accounts that are used exclusively to hold customer funds for the administration of customer benefits, and we have cash and cash equivalents on deposit to meet certain regulatory requirements. These amounts totaled $300 and $258 at September 30, 2023 and December 31, 2022, respectively, and are included in the cash and cash equivalents line on our consolidated balance sheets.

Cash and Cash Equivalents: Cash and cash equivalents includes available cash and all highly liquid investments with maturities of three months or less when purchased. We control a number of bank accounts that are used exclusively to hold customer funds for the administration of customer benefits, and we have cash and cash equivalents on deposit to meet certain regulatory requirements. These amounts totaled $258 and $173 at December 31, 2022 and 2021, respectively, and are included in the cash and cash equivalents line on our consolidated balance sheets.

Investment, Policy

Investments: We classify fixed maturity securities in our investment portfolio as “available-for-sale” and report those securities at fair value. Certain fixed maturity securities are available to support current operations and, accordingly, we classify such investments as current assets without regard to their contractual maturity. Investments used to satisfy contractual, regulatory or other requirements are classified as long-term, without regard to contractual maturity.

If a fixed maturity security is in an unrealized loss position and we have the intent to sell the fixed maturity security, or it is more likely than not that we will have to sell the fixed maturity security before recovery of its amortized cost basis, we write down the fixed maturity security’s cost basis to fair value and record an impairment loss in our consolidated statements of income. For impaired fixed maturity securities that we do not intend to sell or if it is more likely than not that we will not have to sell such securities, but we expect that we will not fully recover the amortized cost basis, we recognize the credit component of the impairment as an allowance for credit loss in our consolidated balance sheets and record an impairment loss in our consolidated statements of income. The non-credit component of the impairment is recognized in accumulated other comprehensive loss. Furthermore, unrealized losses entirely caused by non-credit-related factors related to fixed

maturity securities for which we expect to fully recover the amortized cost basis continue to be recognized in accumulated other comprehensive loss.

The credit component of an impairment is determined primarily by comparing the net present value of projected future cash flows with the amortized cost basis of the fixed maturity security. The net present value is calculated by discounting our best estimate of projected future cash flows at the effective interest rate implicit in the fixed maturity security at the date of purchase. For mortgage-backed and asset-backed securities, cash flow estimates are based on assumptions regarding the underlying collateral, including prepayment speeds, vintage, type of underlying asset, geographic concentrations, default rates, recoveries and changes in value. For all other securities, cash flow estimates are driven by assumptions regarding probability of default, including changes in credit ratings and estimates regarding timing and amount of recoveries associated with a default.

For asset-backed securities included in fixed maturity securities, we recognize income using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The net investment in the securities is adjusted to the amount that would have existed had the new effective yield been applied since the purchase date of the securities. Such adjustments are reported within net investment income.

The changes in fair value of our marketable equity securities are recognized in our results of operations within net gains and losses on financial instruments. Certain marketable equity securities are held to satisfy contractual obligations and are reported under the caption “Other invested assets” in our consolidated balance sheets.

We have corporate-owned life insurance policies on certain participants in our deferred compensation plans and other members of management. The cash surrender value of the corporate-owned life insurance policies is reported under the caption “Other invested assets” in our consolidated balance sheets.

We use the equity method of accounting for investments in companies in which our ownership interest may enable us to influence the operating or financial decisions of the investee company. Our proportionate share of equity in net income of these unconsolidated affiliates is reported within net investment income. The equity method investments are reported under the caption “Other invested assets” in our consolidated balance sheets.

Investment income is recorded when earned. All securities sold resulting in investment gains and losses are recorded on the trade date. Realized gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold.

We participate in securities lending programs whereby marketable securities in our investment portfolio are transferred to independent brokers or dealers in exchange for cash and securities collateral. We recognize the collateral as an asset, which is reported under the caption “Other current assets” on our consolidated balance sheets, and we record a corresponding liability for the obligation to return the collateral to the borrower, which is reported under the caption “Other current liabilities.” The securities on loan are reported in the applicable investment category on our consolidated balance sheets. Unrealized gains or losses on securities lending collateral are included in accumulated other comprehensive loss as a separate component of shareholders’ equity. The market value of loaned securities and that of the collateral pledged can fluctuate in non-synchronized fashions. To the extent the loaned securities’ value appreciates faster or depreciates slower than the value of the collateral pledged, we are exposed to the risk of the shortfall. As a primary mitigating mechanism, the loaned securities and collateral pledged are marked to market on a daily basis and the shortfall, if any, is collected accordingly. Secondarily, the collateral level is set at 102% of the value of the loaned securities, which provides a cushion before any shortfall arises. The investment of the cash collateral is subject to market risk, which is managed by limiting the investments to higher quality and shorter duration instruments.

Receivable

Receivables: Receivables are reported net of amounts for expected credit losses. The allowance for doubtful accounts is based on historical collection trends, future forecasts and our judgment regarding the ability to collect specific accounts.

Premium receivables include the uncollected amounts from employer risk-based groups, individuals and government programs for insurance services. Premium receivables are reported net of an allowance for doubtful accounts of $188 and $152 at September 30, 2023 and December 31, 2022, respectively.

Self-funded receivables include administrative fees, claims and other amounts due from fee-based customers for administrative services. Self-funded receivables are reported net of an allowance for doubtful accounts of $93 and $68 at September 30, 2023 and December 31, 2022, respectively.

Other receivables include pharmacy rebates, provider advances, claims recoveries, reinsurance receivables, proceeds due from brokers on investment trades, accrued investment income and other miscellaneous amounts due to us. These receivables are reported net of an allowance for doubtful accounts of $875 and $744 at September 30, 2023 and December 31, 2022, respectively.

Premium receivables include the uncollected amounts from insured groups, individuals and government programs. Premium receivables are reported net of an allowance for doubtful accounts of $152 and $142 at December 31, 2022 and 2021, respectively.

Self-funded receivables include administrative fees, claims and other amounts due from fee-based customers. Self-funded receivables are reported net of an allowance for doubtful accounts of $68 and $50 at December 31, 2022 and 2021, respectively.

Other receivables include pharmacy rebates, provider advances, claims recoveries, reinsurance receivables, proceeds due from brokers on investment trades, accrued investment income and other miscellaneous amounts due to us. These receivables are reported net of an allowance for doubtful accounts of $744 and $648 at December 31, 2022 and 2021, respectively.

Revenue Recognition

Revenue Recognition: For our non-risk-based contracts, we had no material contract assets, contract liabilities or deferred contract costs recorded on our consolidated balance sheet at September 30, 2023. For the three and nine months ended September 30, 2023 and 2022, revenue recognized from performance obligations related to prior periods, such as changes in transaction price, were not material. For contracts that have an original, expected duration of greater than one year, revenue expected to be recognized in future periods related to unfulfilled contractual performance obligations and contracts with variable consideration related to undelivered performance obligations is not material.

Revenue Recognition: Premiums for risk-based contracts are recognized as revenue over the period insurance coverage is provided, and, if applicable, net of amounts recognized for MLR rebates, risk adjustment, reinsurance and risk corridor under contractual premium stabilization arrangements, the ACA or other regulatory requirements. Premiums may also include performance incentives and penalties, which are recognized based on contractual terms. We estimate amounts receivable and payable under these contractual terms, and to the extent that such estimated amounts vary from the final amounts paid, the adjustments are included in earnings in the period of final settlement. Premium payments from contracted government agencies are based on eligibility lists produced by the government agencies. Premiums related to the unexpired contractual coverage periods are reflected in the accompanying consolidated balance sheets as unearned income. Premiums include revenue adjustments for retrospectively rated contracts where revenue is based on the estimated loss experience of the contract. Premium rates for certain lines of business are subject to approval by the Department of Insurance of each respective state. Additionally, delays in annual premium rate changes from contracted government agencies require that we

defer the recognition of any increases to the period in which the premium rates become final. The value of the impact can be significant in the period in which it is recognized depending on the magnitude of the premium rate increase, the membership to which it applies and the length of the delay between the effective date of the rate increase and the final contract date. Premium rate decreases are recognized in the period the change in premium rate becomes effective and the change in the rate is known, which may be prior to the period when the contract amendment affecting the rate is finalized.

Service fees include revenue from certain group contracts that provide for the group to be at risk for all, or with supplemental insurance arrangements, a portion, of their claims experience. We charge these fee-based groups an administrative fee, which is based on the number of members in a group and the group’s claim experience. In addition, service fees include amounts received for the administration of Medicare, certain other government programs, and administrative services arrangements of our Carelon (Diversified Business Group) subsidiaries, now known as Carelon. Generally, these fee-based arrangements include services which constitute a single suite of services provided and for which consideration is based upon an agreed-upon rate, regardless of the amount of services provided in a given period. As with premiums, these fee-based arrangements may include terms with retroactive rate or membership adjustments, performance incentives and penalties, each of which is a form of variable consideration within the transaction price. As such, these fee-based arrangements contain a single performance obligation that constitutes a series, and revenue is recognized over time as the services are performed. All benefit payments under these programs are excluded from benefit expense.

The determination of whether services are distinct performance obligations that should be accounted for separately or combined as one unit of accounting may require significant judgment. The estimation of variable consideration to be recognized requires significant judgment in the determination of the level of achievement of performance incentives, service level achievements subject to performance penalties, and the completion level of tasks subject to implementation fees.

Product revenue includes revenue for services performed by CarelonRx for unaffiliated pharmacy customers. Unaffiliated pharmacy customers include our fee-based groups that have contracted with CarelonRx for pharmacy services and third-party health plans. Product revenues and costs of goods sold for our affiliated health plans are eliminated in consolidation. Product revenue for pharmacy services is recognized using the gross method at the negotiated contract price when CarelonRx has concluded that it is the principal and it controls the services before prescription drugs are transferred to the customer. CarelonRx determined it is the principal due to its contractual rights to design and develop a listing of prescription drugs offered to the customer (formulary management); its control over establishing the pharmacy network available to the customer to have its prescription fulfilled (network management); and its discretion over establishing the pricing for prescription drugs. Overall, control over these activities indicate CarelonRx is primarily responsible for fulfilling the promise to provide pharmacy services. Product revenue includes ingredient costs (net of any rebates or discounts), including any co-payments made by or on behalf of the customer, and administrative fees. CarelonRx recognizes revenue when control of the prescription drugs is transferred to customers, in an amount it expects to be entitled to in exchange for the products or services provided.

For our non-risk-based contracts, we had no material contract assets, contract liabilities or deferred contract costs recorded on our consolidated balance sheet at December 31, 2022. Revenue recognized in 2022 and 2021 from performance obligations related to prior years, such as due to changes in transaction price, was not material. For contracts that have an original expected duration of greater than one year, revenue expected to be recognized in future periods related to unfulfilled contractual performance obligations and contracts with variable consideration related to undelivered performance obligations is not material.

New Accounting Pronouncements

Recently Adopted Accounting Guidance: In November 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2020-11, Financial Services—Insurance (Topic 944): Effective Date and Early Application (“ASU 2020-11”). The amendments in ASU 2020-11 change the effective date and early application of Accounting Standards Update No. 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, which was issued in November 2018. The amendments in ASU 2020-11 extended the original effective date by one year, and now the amendments are required for our interim and annual reporting periods beginning after December 15, 2022. This standard requires us to review cash flow assumptions for our long-duration insurance contracts at least annually and recognize the effect of changes in future cash flow assumptions in net income. This standard also requires us to update discount rate assumptions quarterly and recognize the effect of changes in these assumptions in other comprehensive income. The rate used to discount our reserves for future policy benefits will be based on an estimate of the yield for an upper-medium grade fixed-income instrument with a duration profile matching that of our liabilities. In addition, this standard changes the amortization method for deferred acquisition costs. We adopted these amendments on January 1, 2023, using the modified retrospective transition method for changes to the liability for future policy benefits and deferred acquisition costs as of the transition date, January 1, 2021. While the adoption did not have an overall material impact, our prior period financial statements presented in this Form 10-Q have been restated to reflect the impacts of our adoption as required by the new standard.

Recent Accounting Guidance Not Yet Adopted: In August 2023, the FASB issued Accounting Standards Update No. 2023-05, Business Combinations—Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement (“ASU 2023-05”). ASU 2023-05 clarifies existing guidance to reduce diversity in practice and is requiring a joint venture to recognize and initially measure its assets and liabilities using a new basis of accounting, at fair value, upon formation. These amendments are effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. We do not believe the adoption of ASU 2023-05 will have a material impact on our consolidated financial statements and disclosures.

There were no other new accounting pronouncements that were issued or became effective since December 31, 2022 that had, or are expected to have, a material impact on our consolidated financial position, results of operations or cash flows.

Recently Adopted Accounting Guidance: In January 2021, the FASB issued Accounting Standards Update No. 2021-01, Reference Rate Reform (Topic 848) (“ASU 2021-01”). The amendments in ASU 2021-01 provide optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of the reference rate reform. The provisions must be applied at a Topic, Subtopic, or Industry Subtopic level for all transactions other than derivatives, which may be applied at a hedging relationship level. We adopted ASU 2021-01 on January 7, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows.

In October 2020, the FASB issued Accounting Standards Update No. 2020-08, Codification Improvements to Subtopic 310-20, Receivables—Nonrefundable Fees and Other Costs (“ASU 2020-08”). The amendments in ASU 2020-08 clarify when an entity should assess whether a callable debt security is within the scope of accounting guidance, which impacts the amortization period for nonrefundable fees and other costs. ASU 2020-08 became effective for interim and annual reporting periods beginning after December 15, 2020. The amendments were applied on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. We adopted ASU 2020-08 on January 1, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows.

In August 2020, the FASB issued Accounting Standards Update No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). The amendments eliminate two of the three accounting models that require separate accounting for convertible features of debt securities, simplify the contract settlement assessment for equity classification, require the use of the if-converted method for all convertible instruments in the diluted earnings per share calculation and expand disclosure requirements. The amendments became effective for our annual and interim reporting periods beginning after December 15, 2021. We adopted ASU 2020-06 on January 1, 2022 using the modified retrospective transition method, which resulted in an increase to our reported debt outstanding of $31, a decrease to our deferred tax liabilities of $8, and a corresponding cumulative-effect reduction to our opening retained earnings of $23, eliminating the bifurcation of the embedded conversion option; these amounts were not material to our overall consolidated financial position. The adoption of ASU 2020-06 did not have an impact on our results of operations or our consolidated cash flows. Use of the if-converted method did not have an impact on our overall earnings per share calculation.

In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). The amendments in ASU 2019-12 remove certain exceptions to the general principles in Accounting Standards Codification Topic 740. The amendments also clarify and amend existing guidance to improve consistent application. The amendments became effective for our annual reporting periods beginning after December 15, 2020. The transition method (retrospective, modified retrospective, or prospective basis) related to the amendments depends on the applicable guidance, and all amendments for which there is no transition guidance specified are to be applied on a prospective basis. We adopted ASU 2019-12 on January 1, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows.

In November 2020, the FASB issued Accounting Standards Update No. 2020-11, Financial Services—Insurance (Topic 944): Effective Date and Early Application (“ASU 2020-11”). The amendments in ASU 2020-11 make changes to the effective date and early application of Accounting Standards Update No. 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts (“ASU 2018-12”), which was issued in November 2018. The amendments in ASU 2020-11 extended the original effective date by one year, with the amendments required for our interim and annual reporting periods beginning after December 15, 2022. This standard requires the Company to review cash flow assumptions for its long-duration insurance contracts at least annually and recognize the effect of changes in future cash flow assumptions in net income. This standard also requires the Company to update discount rate assumptions quarterly and recognize the effect of changes in these assumptions in other comprehensive income. The rate used to discount the Company’s reserves for future policy benefits will be based on an estimate of the yield for an upper-medium grade fixed-income instrument with a duration profile matching that of the Company’s liabilities. In addition, this standard changes the amortization method for deferred acquisition costs. The Company adopted the new standard on January 1, 2023, using the modified retrospective transition method for changes to the liability for future policy benefits and deferred

acquisition costs as of the earliest period presented, January 1, 2021. As a result of applying the long-duration standard using the modified retrospective method, adjustments of $(131), $54 and $0, respectively, were made to shareholders’ net income for the years ended December 31, 2022, 2021 and 2020, which include adjustments to benefit expense of $155, $(74) and $0, respectively. In addition, the following balance sheet adjustments were made at years ended December 31, 2022 and 2021: $(17) and $(4), respectively, to total assets; $47 and $(39), respectively, to total liabilities; $13 and $(19), respectively, to accumulated other comprehensive loss; and $(64) and $35, respectively to shareholders’ equity and total equity. The adoption did not have a material impact on our consolidated financial position, results of operations, cash flows, or related disclosures.

There were no other new accounting pronouncements that were issued or became effective during the year ended December 31, 2022 that had, or are expected to have, a material impact on our financial position, results of operations, cash flows or financial statement disclosures.
