What Does PR-P16 Mean?

CARC P16 indicates the provider is not authorized, registered, or certified to treat workers' compensation patients in the applicable jurisdiction. Many states require providers to register specifically with the WC system, obtain a WC provider certification, or meet specific qualifications before they can treat injured workers and bill the WC carrier.

This denial occurs when the provider has not registered in the state's WC system, the required WC provider certification was not obtained, the provider is practicing outside their authorized jurisdiction, the WC authorization lapsed or expired, or the provider's specialty is not authorized for the specific WC treatment type in the jurisdiction.

Unlike general credentialing issues (CARC B7), P16 is specific to WC provider authorization requirements, which are separate from standard insurance credentialing.

How to Resolve

Verify WC authorization status, appeal with certification if authorized, or obtain authorization and rebill.

  1. Check WC authorization status Verify your WC provider authorization or certification status in the applicable jurisdiction.
  2. Appeal if authorized If you are authorized, appeal with your WC certification number, effective dates, and proof of authorization.
  3. Obtain authorization if not certified If not currently authorized, apply for WC provider certification in the jurisdiction.
  4. Request retroactive authorization If you applied for authorization but it was not effective on the date of service, request retroactive coverage.
  5. Rebill after resolution Once the authorization issue is resolved, resubmit the claim.
  6. Refer if cannot obtain authorization If you cannot obtain WC authorization in the jurisdiction, refer the patient to an authorized WC provider.
Do Not Appeal This Code

Provider Not Authorized for WC Treatment in This Jurisdiction grouped under PR places the financial responsibility on the patient. The specific reason depends on the context of this adjustment — review any accompanying RARC codes for detail. Because this represents a placement of responsibility rather than a coverage denial, an appeal isn't the right action; verify the placement is correct before billing the patient.
