Clean claim: the Medicaid definition and why it matters for payment speed
Clean claim is the Medicaid term for a claim that can be decided with no extra information requested from the provider or from anyone else. The federal rule at 42 CFR 447.45 grades payment speed on clean claims only, requiring states to pay 9 in 10 practitioner claims of that kind inside 30 days of receipt. On a NEMT claim, one missing trip detail can keep it from qualifying.

What makes a claim clean
A claim is clean when the payer can reach a decision using only what you sent and what it already has on file. Nobody has to call you, request a trip log, or wait on another insurer. The federal Medicaid definition sits in 42 CFR 447.45, and it adds three details operators should know:
- Glitches in the state’s own system are excused. If the error started inside the state’s claims processing, the claim can still qualify.
- Fraud investigations and medical necessity reviews are carved out. Claims in either situation are never clean, however complete they look.
- “Claim” has a flexible meaning. It can mean a whole bill, one line on it, or every service for one rider on that bill. Each state plan picks the meaning it uses and can vary it by type of service.
Arizona’s Medicaid statute, A.R.S. 36-2904(G), uses a near-identical definition for AHCCCS, with both carve-outs.
The payment deadlines tied to clean status
The fast payment standards apply only to clean claims. Every other claim falls under a much looser limit of 12 months from receipt.
| Payer | Standard | Where it comes from |
|---|---|---|
| State Medicaid, fee-for-service | Clean practitioner claims: 90% paid by day 30 after receipt and 99% by day 90. Everything else: within 12 months | 42 CFR 447.45(d) |
| Medicaid managed care plan | The federal 30-day and 90-day targets apply through the state contract. A different schedule is allowed only by mutual agreement stated in the contract | 42 CFR 447.46 |
| NEMT broker | The broker’s provider agreement and handbook | Your contract |
Receipt is the date the agency stamps on the claim, and payment is the date of the check or transfer. The percentages grade the state as a whole, so a single claim can still take longer. Our guide on how long Medicaid takes to pay covers real payment cycles.
Why NEMT claims fail the clean test
Federal rules at 42 CFR 447.45(f) list the reviews every state runs before it pays: eligibility on the service date, the provider’s authority to furnish the service, duplicates, the rate limits in the state plan, and other coverage. If the payer cannot complete one of those reviews with what you sent, the claim is not clean. Common gaps on transportation claims:
- No valid authorization. Every New York transportation claim carries the 11-digit prior authorization number printed on the transportation roster, and trips approved under different authorizations must be split onto separate claims. See trip authorization numbers.
- Incomplete trip data. MTM Health’s Virginia and Rhode Island handbooks define a clean claim by the trip log submitted alongside it. That log must hold the trip ID, four timestamps (scheduled pickup, actual pickup, departure, arrival), and the member’s signature, and the trip must still show as completed. Anything missing means a denial.
- Wrong or missing identifiers. Texas tells Medical Transportation Program providers which taxonomy code, benefit code, and diagnosis code to put on every claim, and denies claims from individual transportation participants that leave out required details such as the provider identifier.
- Unresolved other coverage. New York makes the provider decide whether another insurer covers the service, and bill that insurer first when it does or when you are unsure. Arizona wants the primary payer’s explanation of benefits sent with the claim. See third-party liability.
When one of these slips through, the remittance explains it with claim adjustment reason codes, and the fix starts in our guide to NEMT claim denials.
Keeping trip records complete
Much of what a broker checks, such as times and signatures, is captured on the road, not in the billing office. As drivers work, HealthRide keeps a timestamped record of every pickup and drop-off, along with GPS-recorded miles and the signature collected on the driver’s phone. The trip log report turns that into a spreadsheet or PDF when a broker or payer asks for proof.
Frequently asked questions
- Must every clean claim be paid within 30 days?
- Not each one. The federal standard grades the state on its whole pile of clean practitioner claims: it has to clear 90 percent of them in 30 days and 99 percent in 90. Clean also describes whether the payer can decide the claim, not whether the decision is to pay. A clean claim for a service the rider was not covered for still denies.
- Do managed care plans and brokers use the same definition?
- Managed care plans are bound to the federal 30-day and 90-day targets through their state contracts under 42 CFR 447.46. A plan and a provider may still settle on another payment schedule, as long as the contract states it. Brokers write their own terms. MTM Health's 2026 handbooks for Virginia and Rhode Island treat a claim as clean only when the electronic trip log and member signature come with it.
- What should I do when a payer asks for more information?
- Send exactly what it asks for, quickly, and keep a dated record of what you sent. A claim that needed extra information was not clean when it arrived, so the federal 30-day and 90-day payment targets never applied to it. Complete trip records sent with the claim are what keep those requests from coming.
- How long do I have to turn a denied claim into a clean one?
- Each payer sets its own window. In Arizona fee-for-service, the first claim must arrive within 6 months of the trip, and any correction that brings it to clean claim status must be in within 12 months of the trip. Past that point, AHCCCS is not liable for payment.
