How Long Does Health Insurance Have to Process a Claim?

Health insurers generally have 30 days to process a standard claim, but the exact answer to how long health insurance has to process a claim depends on the type of plan you have, whether the care was urgent, and whether the insurer received a complete submission. Employer-sponsored plans follow federal timeframes set by the Department of Labor. Individual and marketplace plans follow state prompt-pay laws, usually 30 to 45 days. Medicare runs on its own 30-day clock. In every case, the clock only starts once the insurer has a clean, error-free claim in hand.

Deadlines for Employer-Sponsored Plans

Most job-based coverage falls under the Employee Retirement Income Security Act, which covers roughly 180 million Americans through group health plans.¹ The Department of Labor’s claims procedure rule at 29 C.F.R. § 2560.503-1 sets three different deadlines depending on what kind of decision you need.²

Urgent care claims: 72 hours. No extension is allowed.
Pre-service claims (approval needed before a procedure): 15 days, with one 15-day extension available if the plan notifies you and the delay is outside its control.
Post-service claims (bills submitted after care): 30 days, with the same one-time 15-day extension.

If the extension is needed because the insurer asked you for more information, the clock pauses from the date of that request until you respond or until 45 days pass, whichever comes first.² A straightforward post-service claim can stretch to 45 days when the insurer uses its extension, but it cannot be extended indefinitely.

What You Can Do if an ERISA Plan Misses Its Deadline

Missing the deadline gives you real leverage. Under the regulation, you are considered to have exhausted the plan’s internal review process. That lets you move directly to a lawsuit under ERISA Section 502(a) without finishing any further internal appeals.³ Ordinarily you would have to climb every rung of appeal before suing, so a blown deadline removes that barrier.

You can also request a copy of your plan document and other plan records in writing. If the plan administrator doesn’t mail them within 30 days, a court can impose a penalty of up to $110 per day for each day the administrator fails to comply.⁴⁵ A written request builds a paper trail and puts pressure on the plan to act.

Medicare’s 30-Day Rule

Medicare runs on its own schedule rather than ERISA or state prompt-pay rules. Under the Social Security Act, Medicare contractors must pay at least 95 percent of clean claims within 30 calendar days of receipt.⁶ The same 30-day standard applies to Part B claims from physicians and suppliers.⁷ Medicare Advantage plans are held to the same 30-day clean claim standard under separate regulations.

If Medicare does not pay within those 30 days, interest begins accruing automatically on the unpaid amount at the rate set by the federal Prompt Payment Act. You do not need to request it. The interest is calculated and paid along with the late payment.

State Prompt-Pay Rules for Individual and Marketplace Plans

Plans outside ERISA follow state prompt-pay laws. That category includes individual policies bought through the marketplace, fully insured small-group plans regulated at the state level, and some government employee plans. Deadlines vary by state, but the common framework requires insurers to pay or deny clean claims within 30 days for electronic submissions and 45 days for paper.

When an insurer misses a state deadline, the main enforcement tool is mandatory interest on the unpaid balance. Rates set by state prompt-pay statutes generally fall between 9 and 18 percent per year, with 12 percent the most common. Many states also let their insurance department fine carriers that show a pattern of late payments.

Because the rules differ meaningfully from state to state, check with your state’s department of insurance for your specific deadline and penalty structure. The National Association of Insurance Commissioners maintains a directory to help you find the right regulator.⁸

The Clock Only Starts on a Clean Claim

Every deadline above runs from the day the insurer receives a clean claim, meaning a submission that is complete and free of errors that would prevent a payment decision. If anything required is missing or wrong, the insurer can reject the submission or send it back. The clock resets.

A clean claim generally needs to include:

Patient identification: full name as shown on the insurance card, member ID, date of birth, and group number if applicable.
Provider identification: the treating provider’s National Provider Identifier.
Service details: date and location of service, plus diagnostic codes (ICD-10) and procedure codes (CPT).
Supporting documentation: anything else needed to show the service was medically necessary, such as prior authorization numbers or clinical notes.

The most common errors that delay processing are mismatched patient names, incorrect member ID numbers, and wrong procedure or diagnosis codes.⁹ If you are filing a claim yourself for an out-of-network provider, check every field against your insurance card before you send it.

When You Have Two Plans

If you are covered by two health plans, such as your own job-based coverage and a spouse’s, the secondary insurer usually will not process your claim until the primary insurer has paid and issued an Explanation of Benefits. The secondary insurer’s processing clock does not start until it receives that information, which can add weeks or months to the time before your claim is fully resolved.

If a coordination-of-benefits issue is holding things up, contact both insurers to confirm which one is primary and make sure the primary carrier has already processed the claim. Sending the secondary insurer a copy of the primary insurer’s Explanation of Benefits can move it along.

What to Do When the Deadline Has Passed

Check your claim status through the insurer’s member portal or app regularly in the first 30 days after care. If a claim is still pending past the applicable legal deadline, act rather than wait.

Call the insurer’s claims department first. Write down the date and time, the representative’s name, any case or reference numbers, and what you were told. Follow up by email or certified mail so there is a written record. If that doesn’t resolve it, your next step depends on the plan type:

For state-regulated plans, file a complaint with your state’s department of insurance. The agency can investigate the carrier and enforce penalties for late payments.⁸
For ERISA-governed plans, contact the Department of Labor’s Employee Benefits Security Administration, which helps participants in employer-sponsored plans and can step in when a plan administrator violates federal claims processing rules.¹⁰

If your employer-sponsored plan has missed its deadline and you have been deemed to have exhausted the internal process, you can also file suit under ERISA Section 502(a) to recover the benefits owed.³ An attorney who handles ERISA disputes can help you decide whether that step is worth it for the amount at stake.
