Prompt Pay Laws: When Does the Health Insurance Claim Payment Clock Start?

There is no single U.S. prompt pay deadline that applies to every health insurance claim. How quickly a payer must act depends on which program or law governs the claim: Medicare, Medicare Advantage and Medicaid each have federal rules, state laws regulate insured commercial products, self-funded employer plans largely fall outside state insurance law, and provider contracts add their own terms. The submission method, the definition of a "clean claim" and whether the payer needs more information can all change the answer.

That makes "the clean claim clock" useful shorthand but a dangerous universal rule. The right question is: which law or contract governs this claim, what event starts its payment period, and what can lawfully interrupt or change that period? This article explains the main rules and how to build that answer. It is general information, not legal advice; significant disputes warrant review by counsel or contracting staff.

Prompt pay laws govern timing after submission

Prompt pay rules exist so that covered claims do not sit unresolved once the payer has what it needs to decide them. Depending on the rule, the payer may have to pay, deny, pay the undisputed portion, or request additional information within a set period, and many rules attach interest or penalties to late payment.

Two details matter as much as the number of days. The first is what starts the clock, which is usually the payer's receipt of the claim, not the date the provider created or sent it. Medicare's claims manual, for example, defines the receipt date as the date the contractor receives the claim and starts the count on the following day. The second is what qualifies, since most rules apply only to "clean" claims, and the definition differs. Prompt pay analysis therefore starts with jurisdiction and plan type, not arithmetic.

The federal rules

Traditional Medicare

For Medicare fee-for-service, the Social Security Act requires that at least 95 percent of clean claims be paid within 30 calendar days of receipt. It defines a clean claim as one with no defect or impropriety, including any lack of required substantiating documentation, or particular circumstance requiring special treatment that prevents timely payment. Interest is owed on clean claims not paid within that window.

Medicare also has a payment floor that works in the other direction: contractors may not pay a claim too early. Electronic claims can be paid no earlier than the 14th day after receipt and paper claims no earlier than the 29th day. For a provider tracking cash flow, that floor is as predictable as the 30-day ceiling.

Medicare Advantage

Medicare Advantage plans follow 42 CFR 422.520. A plan must pay 95 percent of clean claims within 30 days of receipt when the claims come from non-contracted providers (or from enrollees of private fee-for-service plans), must pay interest on clean claims not paid within 30 days, and must pay or deny all other claims from non-contracted providers within 60 calendar days. For contracted providers, the regulation requires a prompt payment provision in the provider contract, with terms agreed by both sides. A contracted provider's payment clock is therefore set by its MA contract, not by the 30-day federal standard.

Medicaid and Medicaid managed care

State Medicaid agencies follow 42 CFR 447.45, which requires them to pay 90 percent of clean claims from practitioners within 30 days of receipt and 99 percent within 90 days. Medicaid's definition is different from Medicare's: a clean claim is one that can be processed without obtaining additional information from the provider or a third party, and it excludes claims from providers under investigation for fraud or abuse and claims under review for medical necessity. Under 42 CFR 447.46, Medicaid managed care contracts must require plans to meet the same 90 percent and 99 percent standards, unless a plan and its providers agree to an alternative payment schedule in their contract.

State prompt pay laws: two examples

State laws regulate insurers and HMOs operating in the state, and they differ in timeframes, triggers, scope and penalties. Two examples show the range.

New York

New York Insurance Law section 3224-a requires insurers and HMOs to pay claims within 30 days of receipt if submitted electronically, and within 45 days if submitted by other means such as paper or fax. The exceptions are where the obligation to pay is not reasonably clear, or where there is a reasonable basis, supported by specific information, to believe the claim was submitted fraudulently. The statute applies to claims from any health care provider.

When the obligation is not reasonably clear, for example because of a good-faith dispute over eligibility, another payer's liability, the amount of the claim or the covered benefits, the insurer must pay any undisputed portion and, within 30 calendar days of receiving the claim, send a written notice. The notice must say whether the claim is denied or partially approved, state the specific reasons for any amount it is not obligated to pay, request any additional information it needs, and identify the specific plan or product. Once the requested information arrives, the 30- or 45-day standard applies again, and if the insurer then decides payment is due, it must pay within 15 days of that determination. Late payment carries interest at the greater of 12 percent per year or the state's corporate tax rate, computed from the date payment was required (no interest is owed if it would be under $2).

New York's rules also show that "clean claim" is not a universal legal term. A 2002 opinion from the state Insurance Department's Office of General Counsel concluded that there is no New York statutory definition of a clean claim and that the term is not used anywhere in the Insurance Law. The state's own consumer guidance still uses "clean claims" informally, but the statute frames the duty around whether the obligation to pay is reasonably clear.

Texas

Texas sets similar timeframes with a narrower scope and much heavier penalties. Under Insurance Code sections 1301.103 (preferred provider plans) and 843.338 (HMOs), an insurer or HMO must determine whether a clean claim from a preferred, participating or contracted provider is payable, and then pay it, pay the undisputed portion with a written explanation, or explain in writing why it will not pay, by the 30th day after receiving an electronic claim or the 45th day after receiving a paper claim. Unlike New York's statute, which covers claims from any health care provider, these sections apply to preferred, participating or contracted providers.

Late payment under section 1301.137 triggers penalties on top of the contracted rate. The penalty is the lesser of 50 percent of the difference between billed charges and the contracted rate, or $100,000. It rises to the lesser of 100 percent of that difference or $200,000 if payment comes 46 to 90 days late, and adds 18 percent annual interest beyond that. Similar tiers apply to underpayments.

These two states are illustrations, not a survey. A reliable state-by-state table would need to specify, for each state, the regulated products, the claim types, the submission methods, the trigger, the deadline, the exceptions and the statutory source, and it would need to be researched from the statutes themselves rather than from secondary summaries.

State laws do not reach every plan

This is one of the most important limits. ERISA, the federal law governing employer benefit plans, preempts state laws that relate to those plans. Its "savings clause" preserves state laws that regulate insurance, but its "deemer clause" provides that an employer benefit plan itself is not deemed an insurance company for purposes of state insurance law. In practice, a fully insured product is generally subject to state prompt pay law, while a self-funded employer plan generally is not, even when the same carrier administers both.

Self-funded plans are not unregulated, but the federal rule that applies to them is different in kind. The Department of Labor's claims procedure regulation requires a plan to notify the claimant of an adverse benefit determination on a post-service claim within 30 days of receipt, with one possible 15-day extension. That is a deadline for notifying the member of a denial, not a deadline for paying a provider, and it carries no interest. For provider operations, the logo on the card is not enough: the funding type determines which framework, if any, sets a payment clock.

Contracts matter alongside statutes

Provider agreements contain claims-payment terms, filing rules, dispute requirements and definitions that interact with applicable law, and in Medicare Advantage the contract is the governing rule for contracted providers. When investigating a late claim, keep both the statutory rule and the relevant contract language. The question is not whether the claim has aged past an internal AR threshold, but whether the payer has missed an enforceable obligation that applies to that account.

Prompt pay is different from timely filing

These two clocks point in opposite directions. Timely filing governs how long the provider has to submit a claim. Prompt pay governs how quickly the payer must act once it has received a qualifying claim. New York's statute contains both: alongside the 30- and 45-day payment rules, it requires providers to submit claims within 120 days of the date of service (90 days for Medicaid managed care plans) unless the parties agree to a period more favorable to the provider.

Confusing the two produces bad work queues. A claim can be filed on time by the provider and still paid late by the payer, or filed late by the provider even though the payer processes it promptly. Our guide to timely filing deadlines covers the provider-side clock.

Build the clock from documented events

A useful prompt pay case record contains the service date, the original submission date, the payer's receipt date, the submission method and receipt evidence, the payer, product and funding type, any requests for additional information and the provider's response dates, the adjudication date, the payment date, and the governing rule or contract term. Receipt evidence can be an EDI acceptance record, a clearinghouse acknowledgment, a payer portal confirmation, a certified-mail or fax confirmation, or another receipt the payer recognizes. The stronger the receipt evidence, the less room there is to dispute when the clock started.

Those fields let the organization calculate elapsed time from facts rather than from claim age, and they make escalation more defensible. Instead of telling a payer "this claim is old," the provider can cite the receipt date, the applicable rule, any intervening information requests and the time elapsed. That depends on clean claims in the first place; see our guide to improving your clean claim rate.

Prompt pay rules work best as exception logic

For most claims, normal electronic adjudication happens without anyone calculating a legal deadline. The value of prompt pay logic is in identifying exceptions: claims that have passed the expected period without a documented reason. Combined with claim status follow-up and payer response history, it lets a work queue separate ordinary aging from claims that appear to have crossed a statutory or contractual threshold.

The qualifier is that the rules must be modeled accurately. A single national "30-day clean claim" trigger would flag self-funded plans, contracted Medicare Advantage claims and claims with legitimate information requests as violations when they are not.

There is no one clean claim clock

For revenue cycle teams, prompt pay is less about memorizing a number than following the right sequence: identify the plan and its funding type, identify the governing rule or contract, establish when the payer received the claim, account for valid information requests and other exceptions, and only then calculate the deadline. That takes longer to explain than "payers have 30 days," but it is far more useful when real money depends on the answer.

FAQ

How long do insurance companies have to pay a claim?

It depends on the program and the law. Traditional Medicare must pay 95 percent of clean claims within 30 days, Medicare Advantage plans must pay 95 percent of clean claims from non-contracted providers within 30 days, and state Medicaid programs must pay 90 percent of clean practitioner claims within 30 days. State laws for insured commercial plans vary; New York and Texas, for example, use 30 days for electronic claims and 45 days for paper. Self-funded employer plans are generally not subject to state prompt pay laws.

What is a clean claim?

There is no single definition. Medicare defines it as a claim with no defect, impropriety or special circumstance that prevents timely payment. Medicaid defines it as a claim that can be processed without additional information from the provider or a third party. Some states, such as New York, do not define the term in statute at all.

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

Generally not. ERISA preempts state laws as applied to self-funded employer plans. Those plans must still give members timely notice of claim denials under Department of Labor rules, but that is not a provider payment deadline.

Is interest owed on late claims?

Often, but the rate and conditions vary. Medicare and Medicare Advantage pay interest on late clean claims. New York requires interest at the greater of 12 percent or the corporate tax rate, and Texas imposes tiered penalties plus 18 percent interest on very late claims.
