Can I appeal a CO-149 or PR-149 denial?

Yes. Appealing is free and it is your legal right. For this code the odds are medium: Miscounts and unlawful dollar caps both get reversed. Fewer than 1 in 100 denials are ever appealed — insurers count on silence.

Who has to pay after a code 149 denial?

Who owes depends on the details. 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 149: what it means — and how to fight it

Denial code 149 (shown on your EOB as CO-149 or PR-149) means: “Lifetime benefit maximum has been reached for this service/benefit category.” In plain English: A lifetime cap on this specific benefit. Dollar caps on essential health benefits are illegal; visit/occurrence caps may stand but the count is often wrong.
