R1 RCM has added a utilization management tool to its Phare Operating System that flags medical necessity denial risks while patients are still in the hospital. The capability, called Phare UM, layers payer-specific intelligence onto a clinical AI engine to surface vulnerable cases in real time - shifting denial prevention work from after the fact to the front end of the revenue cycle.
The tool continuously evaluates clinical evidence alongside payer-specific risk patterns, documentation gaps, and denial vulnerability, according to the company's announcement. It prioritizes cases for review before discharge rather than leaving denial problems to be discovered during back-end claims management.
How Phare UM connects clinical and payer data
Utilization management has traditionally focused on clinical appropriateness and documentation, while payer behavior is managed downstream through denials and appeals. R1's update merges these functions into a single workflow. AI agents handle both clinical judgment and denial risk assessment, generating recommendations based on the company's proprietary data.
The approach tackles what R1 sees as a handoff problem: one team identifies a utilization issue, but a separate team handles the resulting denial. Phare UM lets the same workflow assess whether patients meet payer criteria for payment and what a specific payer is likely to do with the case. "By surfacing the right clinical and payer insights at the right time, Phare UM helps clinicians spend less time gathering information and more time making complex statusing decisions," said Dr. Jennifer Weinberg, VP of physician advisory solutions at R1.
Built on R1's pre-bill architecture
Phare UM is not a standalone product. It sits inside Phare OS, which R1 describes as a revenue operating system connecting clinical records and financial data on a single platform. The system stems from R1's acquisition of Phare Health in October 2025, which brought generative AI capabilities for clinical documentation improvement and complex inpatient coding.
The tool draws on R1's clinical AI engine and a proprietary intelligence layer called Payer Atlas. This network tracks and decodes changing payer behaviors and rules. CEO Joe Flanagan said the tool brings the company's vision to life by pinpointing denial risk sooner and closing documentation gaps before payers spot them. The automated workflow also reviews all patient cases from discharge, surfacing high-need cases to UM teams instead of relying on admission-order queues.
Moving toward an autonomous revenue cycle
Revenue cycle management has long been a top use case for healthcare automation, but the overall process has remained human-led. R1's update points toward a model where technology takes the lead - continuously detecting risk and recommending or initiating next actions, with humans stepping in when their expertise is needed.
Other vendors are making similar moves. Waystar has built the autonomous revenue cycle into its product strategy, describing an agentic network that uses clinical, financial, and administrative data to determine and execute actions within workflows. The goal is shifting from task automation to giving technology enough context to identify problems, decide what should happen next, and carry out some of that work without a person managing every step.
Still, the technology has yet to prove it can close the loop between predicting a denial and preventing one. Providers will need to see whether more intelligence actually reduces denied claims.
Why this matters for management
Phare UM represents a structural change in how denial prevention is staffed and sequenced. By integrating payer intelligence directly into utilization management workflows, the tool reduces the coordination burden between clinical and financial teams. For revenue cycle leaders, the immediate question is whether front-end risk detection can measurably lower denial rates - and whether the technology justifies reallocating staff from back-end appeals work to pre-bill intervention. The autonomous direction also raises a longer-term planning issue: as AI takes on more decision-making in the revenue cycle, the role of human managers will shift toward exception handling and oversight of automated workflows.
