CO-P15 Denial Code: WC medical treatment guideline adjustment

Adjusted under the state's WC medical treatment guidelines (e.g., ODG, state-specific MTGs) — treatment outside guidelines pays differently or not at all.

Why CO-P15 happens

  • Treatment beyond guideline frequency/duration without variance approval

How to fix a CO-P15 denial

  1. 1

    Request a variance/pre-authorization under the state MTG process; appeal with guideline citations
