How Long Do Insurers Have to Pay a Claim? Prompt-Pay Laws Explained

"The check is in the mail" isn't a payment strategy — for payers, it's sometimes a business model. Slow payment earns interest on your money. Prompt-pay laws exist to make that expensive: miss the deadline, owe interest. Here's how the timelines work and how to use them.

What prompt-pay laws require

Nearly every state has a prompt-pay (or "clean claims") statute. The common shape:

A deadline — commonly 30 days for clean electronic claims and 45 days for paper, though exact timeframes vary by state. A "clean claim" generally means one with no defect or missing information that would prevent timely payment.
Interest penalties — if the payer misses the deadline, it owes interest on the late payment, often at a statutory rate.
A definition of clean claim — and this is where disputes live. Payers sometimes argue a claim wasn't "clean" to dodge the deadline; your clean claim rate discipline is your evidence that it was.

Deadlines, rates, and remedies differ state by state — check your state's department of insurance for the specific statute rather than relying on a national summary.

Medicare's 30-day standard

Medicare plays by federal rules: contractors must pay 95% of clean claims within 30 days. In practice, clean electronic Medicare claims are often paid much faster — which makes Medicare a useful benchmark. If your commercial payers average 45+ days while Medicare pays in 14, that's a payer performance conversation backed by data, not frustration.

The ERISA exception

One important carve-out: self-funded employer health plans governed by ERISA are generally exempt from state prompt-pay laws, because federal law preempts state insurance regulation for these plans. A large share of commercial covered lives sit in self-funded plans — so before citing a state statute, confirm whether the plan is fully insured (state law applies) or self-funded (it generally doesn't). Your contract terms still govern either way.

What to do when payment is late

Document the timeline. Submission date, 277CA receipt date, and today's date. Interest accrues from facts, not feelings.
Cite the statute in writing. A written inquiry referencing the specific state prompt-pay provision and requesting the statutory interest gets a different response than a phone call asking "where's my payment?"
Escalate to the DOI. State departments of insurance take prompt-pay complaints — and payers know which providers file them.
Track it as a KPI. Average days-to-pay by payer belongs on your denial management dashboard next to denial rate. Payers that are systematically slow get systematically managed: tighter follow-up cadences, documented complaints, and contract renegotiation leverage.

Slow pay vs denial: a claim that's pending past the prompt-pay deadline is a payment-timing problem, not a denial — don't write it off. And don't confuse it with a contractual adjustment: late-payment interest the payer owes you is revenue, not a rounding error. Claim it.

Frequently asked questions

How long do insurance companies have to pay a claim?

Most states have prompt-pay laws requiring payment of clean claims within about 30–45 days, with interest penalties for late payment. Exact deadlines and rates vary by state — check your state's department of insurance.

What is a clean claim under prompt-pay laws?

Generally, a claim with no defect or missing information that would prevent timely payment. Whether a claim was 'clean' is the most common dispute point, which is why clean-claim discipline matters.

How fast does Medicare pay claims?

Medicare contractors must pay 95% of clean claims within 30 days. Clean electronic Medicare claims are often paid faster, making Medicare a useful payment-speed benchmark.

Do prompt-pay laws apply to self-funded employer plans?

Generally no. Self-funded plans governed by ERISA are typically exempt from state prompt-pay laws under federal preemption. Confirm whether a plan is fully insured or self-funded before citing a state statute.

What can I do about consistently late payments?

Document submission and receipt dates, cite the specific state statute in writing and request statutory interest, file complaints with the state department of insurance, and track days-to-pay by payer as a KPI for contract leverage.
