Description of Business	Description of Business R1 RCM Inc. (the "Company") is a leading provider of technology-enabled revenue cycle management ("RCM") services to healthcare providers, including health systems and hospitals, physicians groups, and municipal and private emergency medical service ("EMS") providers. The Company helps healthcare providers generate sustainable improvements in their operating margins and cash flows while also enhancing patient, physician and staff satisfaction for its customers. The Company achieves these results for its customers by managing healthcare providers’ revenue cycle operations, which encompass processes including patient registration, insurance and benefit verification, medical treatment documentation and coding, bill preparation and collections from patients and payers. The Company does so by deploying a unique operating model that leverages its extensive healthcare site experience, innovative technology and process excellence. The Company assists its RCM customers in managing their revenue cycle operating costs while simultaneously increasing the portion of the maximum potential services revenue they receive. Together, these benefits can generate significant and sustainable improvements in operating margins and cash flows for the Company's customers. The Company's primary service offering consists of end-to-end RCM services for health systems, hospitals, physician groups, and EMS providers, which the Company deploys through an operating partner relationship or a co-managed relationship. Under an operating partner relationship, the Company provides comprehensive revenue cycle infrastructure to providers, including all revenue cycle personnel, technology solutions and process workflow. Under a co-managed relationship, the Company leverages its customers’ existing RCM staff and processes, and supplement them with the Company's infused management, subject matter specialists, proprietary technology solutions and other resources. Under the operating partner model, the Company records higher revenue and expenses due to the fact that almost all of the revenue cycle personnel are employees of the Company and more third-party vendor contracts are controlled by the Company. Under the co-managed model, the majority of the revenue cycle personnel and more third-party vendor contracts remain with the customer and those costs are netted against the Company's co-managed revenue. For the years ended December 31, 2019, 2018, and 2017, substantially all of the Company's net operating and incentive fees from end-to-end RCM services were generated under the operating partner model. The Company also offers modular services, allowing customers to engage the Company for only specific components of its end-to-end RCM service offering, such as physician advisory services ("PAS"), practice management ("PM"), revenue integrity services ("RIS"), patient experience, coding management, and business office. The Company's PAS offering assists healthcare organizations in complying with payer requirements regarding whether to classify a hospital visit as an in-patient or an out-patient observation case for billing purposes. The Company's PM services offer administrative and operational support to allow healthcare providers to focus on delivering high quality patient care and outsource non-core functions to the Company. The Company's RIS offering includes charge capture, charge description master ("CDM") maintenance and pricing services that help providers ensure they are capturing the maximum net compliant revenue for services delivered. The Company's patient experience offering helps patients manage their data in one easy-to-use environment, enabling eligibility validation and insurance plan attribution, demographic accuracy, meeting authorization and referral requirements, medical necessity validation, and patient out-of-pocket cost estimation. The Company's coding management offering drives performance, quality, and consistent results via business intelligence and analysis, human capital management, an accountability framework, and a quality management program. The Company's business office service can help providers with the entire billing function or to specifically recoup revenue that may otherwise be lost by focusing skilled resources in lower priority areas with significant revenue potential. Once implemented, the Company's technology solutions, processes and services are deeply embedded in its customers’ day-to-day revenue cycle operations. The Company believes its service offerings are adaptable to meet an evolving healthcare regulatory environment, technology standards and market trends.
