What Does OA-P9 Mean?

CARC P9 applies to property and casualty claims and indicates no standard CPT or HCPCS code is available for the service provided. This differs from P7 (code not in fee schedule) — P9 specifically means no code exists in the standard medical coding system for this service. This occurs with P&C-specific services like case management or vocational rehabilitation that have no medical billing code, non-standard or experimental treatments, and services unique to the P&C context.

The resolution involves using an unlisted procedure code, providing a detailed service description, and negotiating a rate with the P&C adjuster.
