Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements reflect the Company's financial position as of March 31, 2020, the results of operations of the Company for the three months ended March 31, 2020 and 2019, and the cash flows of the Company for the three months ended March 31, 2020 and 2019. These financial statements include the accounts of R1 RCM Inc. and its wholly-owned subsidiaries. All material intercompany amounts have been eliminated in consolidation. These financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial reporting and as required by the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). Accordingly, certain information and footnote disclosures required for complete financial statements are not included herein. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of the interim financial information, have been included. Operating results for the three months ended March 31, 2020 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2020. When preparing financial statements in conformity with GAAP, the Company must make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures at the date of the financial statements. Actual results could differ from those estimates.
Recently Issued Accounting Standards and Disclosures	Recently Issued Accounting Standards and DisclosuresIn June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model which requires the use of forward-looking information to calculate credit loss estimates. The change will result in earlier recognition of credit losses. The Company adopted ASU 2016-13 effective January 1, 2020 utilizing a modified retrospective transition method. Adoption of the new standard resulted in the recording of additional allowance for credit losses of $1.1 million and a corresponding impact to retained earnings and deferred tax assets. The adoption also required changes to the Company's process of estimating expected credit losses on trade receivables and customer contract assets.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Credit Losses Accounts receivable is comprised of unpaid balances pertaining to modular services and end-to-end RCM customers, net receivable balances for end-to-end RCM customers after considering cost reimbursements owed to such customers, including related accrued balances, and amounts due from physician RCM and PM customers. On January 1, 2020 (the "adoption date"), the Company replaced its previous incurred loss impairment model for estimating credit losses on accounts receivables with an expected loss model prepared in accordance with ASC 326. While the incurred loss impairment model had the Company recognize credit losses when it was probable that a loss had been incurred, ASC 326 requires the Company to estimate future expected credit losses on such instruments before an impairment may occur. On the adoption date the Company recorded an initial increase of $1.1 million to the Company's allowance for credit losses, with an offset recorded as an opening adjustment to accumulated deficit and deferred tax assets. The Company evaluates its accounts receivable for expected credit losses quarterly. The Company maintains an estimated allowance for credit losses to reduce its accounts receivable to the amount that it believes will be collected. This allowance is based on the Company’s historical experience, its assessment of each customer’s ability to pay, the length of time a balance has been outstanding, input from key Company resources assigned to each customer, the status of any ongoing operations with each applicable customer, and environmental factors such as significant shifts in the healthcare environment which the Company believes may have impacted or will impact its customers’ financial health and ability to pay.
Revenue Recognition	Revenue RecognitionThe Company follows the guidance under Topic 606, Revenue from Contracts with Customers (“Topic 606”). Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a service to a customer, which is typically over the contact term. Estimates of variable consideration are included in revenue to the extent that it is probable that a significant reversal of cumulative revenue will not occur once the uncertainty is resolved.
