Who has to pay after a code 96 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 96: what it means — and how to fight it

Denial code 96 (shown on your EOB as CO-96 or PR-96) means: “Non-covered charge(s).” In plain English: A catch-all "we don't cover this." Vague denials are weak denials — make them point to the exact plan language.
