What Does PR-P4 Mean?

CARC P4 indicates the workers' compensation carrier adjudicated the claim as non-compensable, meaning the injury or illness does not qualify for WC benefits under applicable state law. This is different from P2 (not work-related) — P4 specifically means the WC carrier reviewed and determined the claim does not meet the criteria for compensability under the state's WC statute.

Reasons for non-compensability include the employer disputing the claim, the treatment not being causally related to the accepted work injury, the WC benefits not being available for this type of treatment under state law, or the claim failing to meet procedural requirements for compensability.

The appeal path is through the state workers' compensation dispute resolution process, not through the standard insurance appeal process. If the claim is legitimately non-compensable, redirect it to the patient's health insurance.

How to Resolve

Appeal through the WC dispute process if the claim should be compensable, or redirect to health insurance.

  1. Review the non-compensability determination Understand why the WC carrier determined the claim is non-compensable.
  2. Gather supporting documentation Compile the incident report, First Report of Injury, physician causation opinion, and relevant medical records.
  3. Appeal through state WC process File a formal dispute through the state WC dispute resolution process with evidence supporting compensability.
  4. Redirect to health insurance if non-compensable If the claim is genuinely non-compensable, redirect to the patient's health insurance plan.
  5. Update billing records Update the patient's insurance and WC claim information to reflect the determination.
Do Not Appeal This Code

Workers' Compensation Claim Non-Compensable 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.
