What Does CO-P6 Mean?

When paired with Group Code CO, the P&C entitlement denial is contractual. The provider cannot bill the P&C carrier further if entitlement is confirmed as ended.

CARC P6 applies to property and casualty claims and indicates the payer adjusted or denied the claim based on the patient's entitlement to benefits under the P&C policy. The payer determined the patient is not entitled to P&C benefits for this claim due to policy exclusions, expired coverage, reached benefit limits, or other entitlement restrictions.

This code addresses the fundamental question of whether the patient qualifies for benefits under the P&C policy — separate from whether the treatment itself is covered. If the patient's entitlement has expired, the policy excludes the circumstance, or coverage limits have been reached, the claim cannot be processed under P&C.

Common Causes

Cause Frequency
Patient not entitled to P&C benefits The P&C payer determined the patient is not entitled to benefits for this claim based on the policy terms or coverage determination Most Common
Policy coverage exclusion The P&C policy excludes coverage for the specific type of injury, treatment, or circumstance Common
Benefits entitlement period expired The patient's entitlement to P&C benefits for this claim has expired per the policy terms Common
Coverage limits reached The patient has reached the maximum benefits entitlement under the P&C policy Occasional

How to Resolve

  1. Verify entitlement Check the P&C policy for coverage status.
  2. Appeal if incorrect Submit policy documentation showing active entitlement.
  3. Redirect if confirmed Bill the patient's health insurance.
Appeal Guide

Appeal with the P&C policy documentation showing the patient's entitlement to benefits. Include the policy number, coverage terms, and evidence supporting the patient's eligibility for the claimed benefits.
