Who has to pay after a code 30 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 30: what it means — and how to fight it

Denial code 30 (shown on your EOB as CO-30 or PR-30) means: “Payment adjusted because the patient has not met the required eligibility, spend down, waiting, or residency requirements.” In plain English: The plan says you have not met a condition yet — a waiting period, a Medicaid spend-down amount, or a residency rule.

What they're really saying

“Payment adjusted because the patient has not met the required eligibility, spend down, waiting, or residency requirements.”

The plan says you have not met a condition yet — a waiting period, a Medicaid spend-down amount, or a residency rule.

Your odds

Worth fighting — many of these get fixed.

Winnable when the requirement was actually met and simply was not recorded.

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.

How to appeal a code 30 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 plan to name the exact requirement they say you did not meet. Ask the plan in writing which specific requirement was not met and what document proves it. For Medicaid spend-down, submit receipts and bills that count toward the amount. For a waiting period, submit prior creditable-coverage documentation if your plan counts it. For residency, a lease, utility bill, or state ID usually settles it.
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.
