CO-P6: Benefits Entitlement Adjustment

What Does CO-P6 Mean?

CO-P6 indicates the payer determined the patient is not entitled to benefits under the P&C policy, and the denied amount is a contractual write-off. The provider cannot balance-bill the patient for the CO-adjusted amount. The remedy is to verify the entitlement determination and either appeal or redirect to alternate coverage.

CARC P6 is a Property and Casualty adjustment triggered when the payer determines there is an entitlement-to-benefits issue with the claim. This code replaces the older CARC 218 and applies exclusively to P&C claims. The entitlement issue can range from expired or lapsed coverage to policy exclusions that prevent coverage for the specific service.

When P6 appears, the payer is saying the patient did not have valid benefit entitlement at the time of service under the P&C policy. This could mean the policy was not active, the patient did not meet eligibility requirements, the covered benefits for the claim type have been exhausted, or the policy contains exclusions that apply to the service rendered.

The provider's first priority is to determine the specific entitlement issue by reviewing the 835 segments referenced by the payer. If the denial is based on incorrect information (e.g., the policy was actually active at the date of service), an appeal with supporting documentation is warranted. If the entitlement issue is valid, the provider should redirect the claim to the patient's alternate coverage or bill the patient directly.

Common Causes

How to Resolve

Verify the patient's P&C benefit entitlement, appeal if the denial is based on incorrect data, or redirect billing to alternate coverage.

1. Verify policy coverage dates Confirm the P&C policy effective dates and ensure the date of service falls within the coverage period. If the policy was active, gather proof for an appeal.
2. Check benefit limits Determine whether the patient's benefits for this type of service have been exhausted under the P&C policy.
3. Appeal or redirect File an appeal with policy documentation if the entitlement denial is wrong, or redirect the claim to the patient's health insurance if the denial is valid.
4. Post the contractual adjustment If the denial stands, write off the CO-P6 amount as a contractual adjustment and close the claim.

Common RARC Pairings

The RARC code tells you exactly what triggered the CO-P6:

How to Prevent CO-P6

• Verify P&C policy status and benefit entitlement before rendering services using direct payer verification
• Check policy effective dates and benefit limits at every visit to catch lapsed or exhausted coverage early
• Implement automated eligibility verification for P&C claims that flags potential entitlement issues before submission
• Maintain current records of P&C policy details for all patients with active injury claims

General Prevention

• Verify the patient's P&C policy status and entitlement to benefits before providing services
• Check policy effective dates and benefit limits at intake to identify potential entitlement issues
• Stay current with P&C payer policies and jurisdictional regulations regarding benefit entitlement
• Implement automated eligibility verification systems that flag expired or limited P&C coverage
• Train front desk and billing staff on P&C entitlement verification procedures
