Can I appeal a CO-60 or PR-60 denial?

Yes. Appealing is free and it is your legal right. For this code the odds are medium: Usually resolved by the provider rebilling correctly. Fewer than 1 in 100 denials are ever appealed — insurers count on silence.

Who has to pay after a code 60 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 60: what it means — and how to fight it

Denial code 60 (shown on your EOB as CO-60 or PR-60) means: “Charges for outpatient services are not covered when performed within a period of time prior to or after inpatient services.” In plain English: Outpatient care near a hospital stay got bundled into the inpatient bill. This is a billing rule between the hospital and the plan, not usually a bill you owe.

How to appeal a code 60 denial

Decode. You just did — this page is step one.
Set your clock. 180 days for most employer and marketplace plans, 120 for Original Medicare, ~90 for Medicaid, only 65 for Medicare Advantage.
Urgent? If this is care you still need, call and request an expedited appeal — they must decide within 72 hours.
Ask the hospital billing office if this falls under the 3-day payment window. Ask the hospital to confirm whether the service should have been bundled into the inpatient stay (the 3-day / 72-hour payment window). If bundled, you should not be separately billed.
Send it certified. Letter plus evidence, keep copies of everything.
Escalate. Denied again? Independent external review — a doctor who doesn't work for your insurer decides.
