Cohere Health Vendor Deep Dive: The Complete RCM Prior Auth Platform Review (2026)
Cohere Health built its platform on a simple but correct bet: prior authorization is not an administrative problem — it's a clinical decision-making problem being solved with fax machines and phone calls. Six years and $200 million later, they're processing 12 million auth requests a year for 600,000 providers, auto-approving 90% of them with AI. The question for RCM leaders isn't whether the platform works. It's whether the tradeoffs fit your operation.

What Cohere Health Actually Does
Cohere Health sits at the intersection of health plan utilization management and provider prior authorization workflows. That's a meaningful distinction from most PA vendors, which are pure provider-side tools that help practices submit auths faster. Cohere's platform is deployed on the payer side — health plans use Cohere to transform how they manage utilization review, then surface the benefit to providers through streamlined submission and real-time clinical decision support.
