Business Combination and Asset Acquisition [Abstract]
Acquisitions and Divestitures	Acquisitions and Divestitures On January 5, 2023, the Company completed the divestiture of HealthSmart, its third-party health plan administration business. On January 10, 2023, the Company signed and closed on a definitive agreement to divest Centurion, its prison healthcare business. During 2022, the Company recorded impairment charges related to goodwill and other current assets associated with the divestiture. During the second quarter of 2023, the Company recognized a $15 million gain on the divestiture of the Centurion business reflecting additional proceeds for contingent consideration, partially offset by net working capital adjustments. The gain is included in investment and other income in the Consolidated Statements of Operations. On January 20, 2023, the Company completed the divestiture of Magellan Specialty Health for approximately $646 million in cash and stock, including an estimated working capital adjustment, and recognized a pre-tax gain of $79 million. The stock consideration was subsequently sold in April 2023 for cash proceeds of $245 million. The Company could also receive up to an additional $150 million in cash and stock in 2024 based on certain 2023 performance metrics. The Company will recognize the appropriate amount of contingent consideration related to the additional $150 million when realized or realizable. On June 13, 2023, the Company completed the divestiture of its majority stake in Apixio. The Company recognized a pre-tax gain of $91 million, or $63 million after-tax, which is included in investment and other income in the Consolidated Statements of Operations. During the second quarter of 2023, the Company recognized an additional $13 million expense related to the divestiture of its Spanish and Central European businesses, in addition to the previously recorded impairment charge of $163 million, or $140 million after-tax. The expense is included in investment and other income in the Consolidated Statements of Operations. Circle Health Group Divestiture On August 28, 2023, the Company signed a definitive agreement to sell Circle Health Group (Circle Health), one of the U.K.'s largest independent hospital operators, which is included in the Other segment. As of September 30, 2023, the assets and liabilities of Circle Health were considered held for sale resulting in $3,744 million of assets held for sale in other current assets and $2,947 million of liabilities held for sale in accounts payable and accrued expenses in the Consolidated Balance Sheet. The majority of the held for sale assets were previously reported as other long-term assets, goodwill and property, software and equipment. The majority of the liabilities were previously reported as debt and other long-term liabilities. During the third quarter of 2023, the Company recorded an impairment charge related to goodwill associated with the pending divestiture of $251 million, or $269 million after-tax. In order to manage the foreign exchange risk on the sale price associated with the pending divestiture of Circle Health, in August 2023 the Company entered into a foreign currency swap agreement for a notional amount of $931 million, to sell £740 million. The swap agreement was formally designated and qualified as a cash flow hedge. The swap expires on March 28, 2024. The gain or loss due to changes in the fair value of the foreign currency swap is recorded in other comprehensive income until the Circle Health divestiture closes, at which time the gain or loss will be recorded in earnings to the same line in the Consolidated Statement of Operations as the gain or loss on sale. The fair value of the swap agreement as of September 30, 2023 was $27 million, which was recorded in other current assets in the Consolidated Balance Sheet.
