What Denialbase does
Health insurers deny 14% of in-network claims on average — and most are never appealed because the workflow is slow, paper-heavy, and requires specialized expertise. Denialbase automates the 80% of each appeal that is mechanical:Detect
Upload an EOB, 835, or denial letter. Our LLM pipeline identifies the denial reason, CARC/RARC codes, deadline, and the patient/claim context.
Strategize
The Strategy Advisor recommends an appeal path (peer-to-peer, formal written appeal, IRO) based on the denial type, plan rules, and state/federal regulations.
