How to appeal an Eligibility / Coverage Not in Effect denial
An eligibility denial means the payer says the patient wasn't covered on the date of service, coverage had ended, hadn't started, or the member couldn't be matched to the plan.
Common code: CARC 27 (after coverage terminated) / 26 / 31 (patient not identified as insured)Why payers issue it
- An old or wrong plan was on file at check-in
- Eligibility changed retroactively after the visit
- The member ID or date of birth didn't match the payer's records
- The patient had different primary coverage that day
What overturns it
- Verify eligibility for the exact date of service and pull the corrected plan details
- Show retroactive reinstatement or the true effective dates
- Correct the member ID or demographics to match payer records
- Rebill the correct payer when coverage actually sat elsewhere
Worth appealing? Eligibility denials are usually a data or timing problem, not a real coverage gap, verifying the plan for the actual date of service turns many of them into paid claims.
