Who has to pay after a code 140 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 140: what it means — and how to fight it

Denial code 140 (shown on your EOB as CO-140 or PR-140) means: “Patient/Insured health identification number and name do not match.” In plain English: Your name and member ID don't match their records — a typo, not a denial of your care. Fixing the info usually clears it.

What they're really saying

“Patient/Insured health identification number and name do not match.”

Your name and member ID don't match their records — a typo, not a denial of your care. Fixing the info usually clears it.

Your odds

Strong — this type of denial has real weaknesses.

Correcting the ID or name resolves nearly all of these.

Fewer than 1 in 100 denied claims are ever appealed. When people do appeal, roughly 4 in 10 win the first round — and independent external review overturns 40–50% of what reaches it.
