Can I appeal a CO-7 or PR-7 denial?

Yes. Appealing is free and it is your legal right. For this code the odds are high: These reverse quickly once records are corrected. Fewer than 1 in 100 denials are ever appealed — insurers count on silence.

Who has to pay after a code 7 denial?

Usually the provider's problem — not yours. The letters in front of the number matter: CO (contractual obligation) usually means an in-network provider must absorb it, while PR (patient responsibility) means the plan says you owe it.

How long do I have to appeal?

It depends on your coverage: 180 days for most employer and marketplace plans, 120 days for Original Medicare, about 90 days for Medicaid (varies by state), and only 65 days for Medicare Advantage. Set your deadline clock before you do anything else.

Denial code 7: what it means — and how to fight it

Denial code 7 (shown on your EOB as CO-7 or PR-7) means: “The procedure/revenue code is inconsistent with the patient's gender.” In plain English: The billed procedure doesn't match the sex listed in their records. Often a records error — and sometimes a denial that wrongly ignores your actual medical needs.

Decode. You just did — this page is step one.

Urgent? If this is care you still need, call and request an expedited appeal — they must decide within 72 hours.
