PR-P3: Workers' Compensation Case Settled — Patient Responsibility
The patient owes this amount per the WC settlement. Collect from the patient or their WCMSA fund.
What Does PR-P3 Mean?
PR-P3 assigns the full financial responsibility to the patient based on the terms of the workers' compensation settlement. The WC carrier is no longer liable, and the settlement agreement specifies that the patient must pay for ongoing treatment. If a WCMSA was established, the funds in that arrangement should be used first. The provider is expected to collect from the patient or WCMSA directly.
CARC P3 appears when a workers' compensation case has reached a settlement and the patient has assumed responsibility for future medical costs related to the work injury. This code is exclusively for workers' compensation claims and is always paired with Group Code PR, because the settled WC case shifts the financial obligation directly to the patient.
The most common scenario behind P3 involves a Workers' Compensation Medicare Set-Aside Arrangement (WCMSA). When a WC case settles, a portion of the settlement may be allocated to cover future injury-related medical expenses. The patient must exhaust those WCMSA funds on qualifying medical services before Medicare or other payers step in. If the WCMSA funds are available, the provider should coordinate billing through the WCMSA administrator rather than billing the patient directly out of pocket.
P3 can catch providers off guard if they are unaware the patient's WC case has been settled. The carrier may have been paying claims for months or years before the settlement, and the transition from carrier-paid to patient-paid can happen abruptly. Providers who treat WC patients long-term should establish workflows to check WC case status at every visit. Once a P3 appears, the provider needs to understand the settlement terms — particularly whether a WCMSA exists, how much remains in the fund, and what services are covered — before determining the correct billing path.
Common Causes
| Cause | Frequency |
|---|---|
| Workers' compensation case settled with Medicare Set-Aside The WC case has been settled and a Medicare Set-Aside Arrangement (WCMSA) was established to cover future medical treatment related to the work injury. The patient must pay from WCMSA funds before Medicare covers these services | Most Common |
| WC settlement with patient responsibility clause The workers' compensation settlement agreement specifies that the patient assumes financial responsibility for ongoing treatment costs related to the injury | Most Common |
| WCMSA funds exhausted or misapplied The patient's Medicare Set-Aside funds have been depleted or the service falls outside the scope of the WCMSA, but the patient remains responsible per the settlement terms | Common |
| Provider unaware of settlement status The provider was not informed that the WC case was settled and continued billing the WC carrier instead of the patient or WCMSA administrator | Common |
How to Resolve
Review the settlement documentation, determine whether WCMSA funds are available, and collect the patient's share.
- Review settlement terms Obtain and review the WC settlement agreement to understand exactly what the patient is responsible for and whether WCMSA funds should cover the charges.
- Coordinate with WCMSA if applicable Contact the WCMSA administrator to submit the claim for payment from the set-aside fund. Provide medical records showing the service relates to the original WC injury.
- Transfer balance to patient If no WCMSA exists or funds are exhausted, post the charges to the patient's ledger and issue a statement with the settlement reference.
- Offer payment arrangements Contact the patient to explain their obligation under the settlement. For larger balances, offer structured payment plans to support collection.
This adjustment is correct per the patient's benefit plan. The amount is the patient's financial responsibility.
Common RARC Pairings
The RARC code tells you exactly what triggered the PR-P3:
| RARC | Description |
|---|---|
| N381 | Alert: Consult your contractual agreement for restrictions, billing, and payment information related to these charges. |
| N591 | Alert: This adjustment is based on the terms of the workers' compensation settlement. Review settlement documents for patient responsibility details. |
How to Prevent PR-P3
- Check the status of WC cases at every patient visit to catch settlements before claims are submitted to a closed case
- Collect alternate insurance information and WCMSA details at intake for all WC patients
- Flag settled WC cases in the practice management system to prevent claims from being submitted to the WC carrier after settlement
- Communicate estimated costs to patients whose WC cases have settled before rendering non-emergency services
General Prevention
- Ask patients about the status of their workers' compensation case at every visit and document any settlement changes
- Establish workflows to flag settled WC cases in the practice management system so front desk staff can redirect billing appropriately
- Verify workers' compensation coverage and case status before each service to catch settled cases early
- Maintain a record of WCMSA details for WC patients, including fund administrator contact information and remaining balance
- Clearly communicate financial responsibility to patients whose WC cases have been settled, including estimated costs before treatment
- Train billing staff on WCMSA billing rules and the proper sequence of payer responsibility after WC settlement
