Prompt pay laws by state: insurer payment deadlines

A prompt pay law sets the number of days a health insurer has to pay or deny a clean claim before interest or penalties start. The days run from about 15 to 60 depending on the state, and many differ between electronic and paper claims. The table below compares the states we have verified.

Quick answer
Typical deadline30 to 45 days for a clean claim
Fastest in the table15 days (New Hampshire, electronic; North Dakota, business days)
Interest10 to 18 percent a year in most states
Self-funded plansGenerally outside state prompt pay law
ComplaintsState insurance department

In short: prompt pay is state law, so the deadline, the interest rate and the penalty depend on the state that regulates the plan. Most states give 30 to 45 days to pay a clean claim and charge interest of 10 to 18 percent a year. State laws generally do not reach self-funded employer plans, Medicare or Medicaid.

What is a prompt pay law?

A prompt pay law is a state statute or rule that makes a health insurer pay, deny or contest a clean claim within a set number of days. If the insurer is late, it owes interest and sometimes a penalty. The state insurance department enforces it.

A payer's timely filing limit for you is a separate clock; see timely filing limits by payer.

Medicaid is separate. Under 42 CFR 447.45(d), a state Medicaid agency must pay 90 percent of clean claims from practitioners within 30 days of receipt and 99 percent within 90 days. Those are targets for the agency's claims overall, not a deadline on one claim.

How many days does an insurer have to pay a clean claim in my state?

The table gives the deadline and interest for commercial insurers as each statute or regulation states them, with a link to the text. A state marked "See the state page" does not have a figure we can state from its text, so use the state page. Confirm the current text before you send a demand.

What counts as a clean claim under state law?

Most statutes define a clean claim as one with no defect or impropriety, including missing required documentation. The clock starts when the insurer receives a clean claim, so a defective claim may not start it.

  • Alaska: no defect or impropriety, including missing substantiating documentation (AS 21.36.495)
  • Delaware: a CMS-1500, UB form or X12N 837 claim (Regulation 1310)
  • South Carolina: the claim must be received within 120 business days of service to be clean (S.C. Code 38-59-210)

The clearinghouse acceptance report proves the receipt date, the evidence in a late-payment dispute.

Do prompt pay laws apply to self-funded plans?

Usually not, according to the state regulators that speak to it. The Illinois Department of Insurance says the prompt pay law does not apply to self-insured plans, Medicare or Medicaid. The Missouri Department of Commerce and Insurance says the same of self-insured employers and health and welfare benefit plans. South Carolina's Department of Insurance says state patient protections do not apply when an employer self-insures.

Ohio's statute excludes Medicare Advantage, Medicaid, TRICARE and self-insured employer plans to the extent federal law preempts the state. Check the plan type before you cite a state statute, and ask for the plan document if it is self-funded.

Can I collect interest on a late-paid claim?

Yes, where the statute provides for it, and in several states the insurer must add it without a demand. California requires the plan to add it automatically, with a fee of the greater of $15 or 10 percent of the interest if it does not. Maryland, the District of Columbia and Hawaii also require it to be added without a separate claim.

Small amounts can fall out: Alaska skips interest of $1 or less, Idaho under $4, and Montana pays only when interest exceeds $5.

Example

Illustrative numbers. An insurer in Nebraska receives an electronic clean claim for $3,000 on Mon, Feb 2, 2026. Thirty calendar days later is Wed, Mar 4, 2026. It pays on Tue, Mar 24, 2026, 20 days late.

Rate12 percent per year (Neb. Rev. Stat. 44-8005)
Interest owed, simple, prorated by day$3,000 x 12% x 20 / 365 = $19.73
NoteThe statute sets no day-count method, so confirm the payer's before disputing a small difference

Where do I file a prompt pay complaint?

With the insurance department of the state that regulates the plan. The NAIC's State Insurance Departments page lets you find your state's department and file a complaint. South Carolina, for example, uses doi.sc.gov/complaint.

Send the claim copy, receipt report, remittance advice and payment date. If late payments hurt cash flow, our denial management and accounts receivable teams can help.

01What is a prompt pay law?

It is a state law requiring a health insurer to pay or deny a clean claim within a fixed number of days, with interest or penalties if it is late. The state insurance department enforces it. Each state sets its own days, interest rate and exceptions.

02How many days does an insurer have to pay a clean claim in my state?

Most states allow 30 to 45 days, and many give a shorter period for electronic claims. Some differ: New Hampshire allows 15 days for electronic claims, Virginia 40 days and North Dakota 15 business days. Check your state's row in the table.

03Do prompt pay laws apply to self-funded plans?

Generally not. Illinois, Missouri and South Carolina regulators say their rules do not reach self-insured employer plans, and Ohio excludes them to the extent federal law preempts. Check the plan type, and ask for the plan document if the plan is self-funded.

04Can I collect interest on a late-paid claim?

Yes, where the state statute provides interest, such as 12 percent a year in Nebraska or 18 percent in North Carolina. Some states require the insurer to add it automatically, and some skip small amounts, for example $1 or less in Alaska or under $4 in Idaho.

05What counts as a clean claim under state law?

Generally a claim with no defect or impropriety, including missing required documentation. Definitions differ. Delaware ties it to a CMS-1500, UB form or X12N 837, and South Carolina requires receipt within 120 business days of service. Keep the clearinghouse receipt as proof.

06Where do I file a prompt pay complaint?

File it with the state insurance department that regulates the plan, which you can find through the NAIC State Insurance Departments page. Include the claim, proof of the receipt date, the remittance advice, the payment date and earlier correspondence with the payer.
