Cohere Health deployed Cohere Validate, an AI-powered claims auditing system that automatically scans medical records and insurance claims to identify potential overpayments and coding errors, helping health plans catch billing inaccuracies before or after payments are made.

Cohere Validate, launched in September 2025 following Cohere's acquisition of ZignaAI, uses machine learning algorithms to analyze claims against pre-service clinical data, plan policies, provider contracts, and billing codes to flag claims most likely to result in audit findings. The platform includes specialized autonomous agents — such as the Sepsis Audit Agent, launched in November 2025 — that scan hundreds of pages of medical records without human initiation, validate diagnoses against clinical criteria, automatically assign diagnosis-related groups (DRGs), and calculate reimbursement amounts. Early adopter health plans reported the Sepsis Audit Agent matching the throughput of 2–3 full-time auditors. Traditional payment integrity has relied on manual human auditors reviewing claims after payment; Cohere's system shifts this work upstream to catch errors before payment and automates the bulk of initial document review.
