Who R1 RCM is best for
R1 RCM began as Accretive Health in 2003, renamed itself in 2017 and was taken private in November 2024 by TowerBrook Capital Partners and Clayton, Dubilier & Rice. It works with hospitals, health systems and physician groups, either running the revenue cycle end to end or providing specific services and technology. R1 says it partners with about 1,000 providers, including 95 of the top 100 US health systems.
Best for
- Health systems and hospitals considering full revenue cycle outsourcing
- Large physician groups that want coding, billing and denials work handled by an outside team
- Systems with complex inpatient coding and DRG audit needs
Not ideal for
- Small independent practices (1 to 20 providers)
- Buyers that want self-serve, published-price software
- Practices that want to keep all billing work in-house on their own EHR

R1 RCM pricing
R1 does not publish pricing; engagements are quoted per organization. Cost depends on scope (which functions R1 takes over), volume, payer mix, staff transition and technology licensing. Outsourced revenue cycle contracts are commonly structured as a percentage of collections, a fixed fee or a mix with performance terms. Ask for technology and services fees to be split out.
Key features
R1's technology runs on the Phare Operating System (Phare OS), built in R37, its AI lab. Named products include:
- Phare Access: insurance verification, prior authorization, patient intake and eligibility
- Phare Claim: autonomous inpatient coding
- Phare Flow: AI agents that follow claims from status checks through denial appeals
- AR Recovery and Denial Management solutions (announced April 2026)
- Prior Authorization and Insurance Discovery solutions
Services cover patient access, mid-cycle coding and clinical documentation integrity, and business office billing, collections, denials and AR follow-up. In August 2026 R1 announced a deal to acquire Humata Health, a prior authorization technology company.
HIPAA, security and integrations
Because R1 handles protected health information for providers, HIPAA requires a business associate agreement with each client; R1 does not publish its BAA terms. The public materials reviewed for this page do not list certifications such as SOC 2 or HITRUST, so request current attestations during procurement. R1 says Phare OS is integrated with all major EHR systems and banks and connects to more than 1,000 payers.
