PR-B12: Services Not Documented in Patient Medical Records

What Does PR-B12 Mean?

When paired with Group Code PR, the payer determined the service was not provided based on the records, assigning patient responsibility. Appeal with complete medical records to remove patient liability if the service was documented.

CARC B12 indicates the payer reviewed the medical records and could not find documentation supporting the services billed on the claim. This denial typically results from a medical records review, post-payment audit, or a documentation request where the records submitted did not contain evidence of the billed services.

The issue may be that records were not submitted when the payer requested them, the submitted records are incomplete and lack sufficient detail, the coding does not match what the medical record describes, or a post-payment audit found the documentation does not support the services originally billed and paid.

This is a documentation issue, not a coverage determination. The payer is not saying the service was not covered — it is saying the medical record does not prove the service was provided. The appeal path involves submitting the complete medical record with comprehensive clinical documentation.

How to Resolve
