Rather than forcing health systems into monolithic rip-and-replace implementations, Phare OS offers a modular path supported by outcome-based pricing, allowing hospitals to deploy targeted automation where financial leakage is most acute and expand across the revenue cycle over time. Four modules are commercially available immediately—Phare Auth, Phare Audit, Phare UM, and Phare Denials—while Phare CDI and Phare Recovery are currently operating in early access ahead of broad commercial availability in 2027.

All six workflow engines draw upon a single underlying intelligence foundation. A unified Data Platform reconciles clinical and financial records, feeding Phare Intelligence, a clinical reasoning engine that evaluates documentation against payer medical necessity criteria. Powering these determinations is Payer Atlas, an intelligence layer informed by more than 1.25 billion annual payer transactions and real-time monitoring of over 115,000 commercial and government payer policies.

Within this connected environment, each module executes specialized tasks while feeding data back into the core system. Following the closing of R1’s acquisition of Humata Health, Phare Auth automates prior authorizations at the point of order entry, while Phare UM manages concurrent utilization reviews and Phare CDI ensures clinical documentation integrity before discharge. Immediately prior to billing, Phare Audit scrubs claims for coding accuracy. On the back end, the newly launched Phare Denials automates technical and clinical appeal creation by pulling the original authorization and medical necessity logic directly into the appeal packet, while Phare Recovery identifies post-payment underpayments. Crucially, payer adjudication outcomes captured by Phare Denials feed directly upstream into pre-bill modules, preventing recurring denial patterns before future claims leave the clearinghouse.
