Every state Medicaid program puts a clock on your claims. Submit inside the window and a clean claim gets paid; submit a day late and the trip is written off, no matter how well you documented it. This is one of the few billing rules with almost no forgiveness.
This reference lays out the fee-for-service timely filing limits NEMT operators most often ask about, then explains why broker and managed-care deadlines usually matter more than the state number. Every figure below is a starting point — as commonly published, always confirm your current state manual and broker or plan contract. This is operational guidance, not legal advice.
What is timely filing in NEMT billing?
Timely filing is the maximum time you have to submit a claim after the date of service. The clock starts on the day the trip was completed and runs until the payer's deadline — after that, the claim is denied for timeliness alone, regardless of whether the ride was covered and correctly documented.
For NEMT that window is set by whoever pays the claim. A state Medicaid agency paying fee-for-service uses one rule; a broker or managed-care plan paying under contract sets its own, usually shorter. Missing the deadline is a self-inflicted denial, which is why it belongs at the top of every billing checklist. The habits that prevent it are the same ones covered in our NEMT billing guide.
How long do I have to file an NEMT claim in my state?
The table below shows fee-for-service timely filing windows for states NEMT operators ask about most. These are the state Medicaid rules — where the note says confirm your broker or plan, treat the contract deadline as the one that governs your claim. All figures are as commonly published; verify the current number before you rely on it.
| State | Timely filing window | Claims system / note |
|---|---|---|
| New York | 90 days (standard) | eMedNY; some materials cite up to 6 months, confirm the current Transportation Manual |
| Texas | 95 days from date of service | TMHP; new providers get 95 days from NPI issuance and within 365 days of service |
| Illinois | 180 days | HFS; override process exists |
| Pennsylvania | 180 days (general Medical Assistance) | PROMISe; a shorter MATP-specific figure is unconfirmed, confirm with your county program |
| Georgia | About 180 days (general) | GAMMIS; a 9-month NEMT figure is unconfirmed, confirm the Verida contract |
| California | 12 months (fee-for-service) | Medi-Cal; broker/plan windows are shorter |
| Florida | 12 months (fee-for-service) | FMMIS; plans may set tighter windows |
| New Jersey | 12 months (general) | NJMMIS; Modivcare's brokered window is shorter, confirm your contract |
| Michigan | 12 months (general) | CHAMPS |
| Ohio | About 365 days FFS; managed care roughly 6 months | OMES/Gainwell; plan-specific |
| North Carolina | 365 days from first date of service | NCTracks |
| Virginia | 6-month broker figure is unconfirmed | Confirm with DMAS / your plan's broker |
Read the pattern, not just the row: several states publish a generous fee-for-service window, but the plan or broker that actually pays you can cut it in half. When two numbers apply, the shorter one is your real deadline.

Most NEMT trips today are paid through a broker or a managed-care plan, not straight fee-for-service. Those payers operate under a contract, and the contract almost always sets a filing window tighter than the state's fee-for-service rule — 30, 60, or 90 days is common where the state allows a year.
That means the state number in the table can be a trap. If California allows 12 months but your managed-care plan's contract says 90 days, 90 days is your deadline, and a claim filed in month four is dead. Always file to the tighter of the two windows, and read the contract rather than assuming the state rule protects you.
This is also why a generic biller can quietly cost you trips. Knowing which broker pays which rider, and what each contract's window is, is core to a specialized NEMT Medicaid billing service and to end-to-end revenue cycle management.
How do you never miss a timely-filing deadline?
The reliable defense is speed, not tracking spreadsheets that count down to a cliff. Build the habit of submitting every clean claim within 24 to 48 hours of trip completion, and the deadline stops being a risk because you are never anywhere near it.
Four practices make that dependable:
- Submit within 24 to 48 hours. The sooner a claim is in, the sooner it pays and the sooner any error surfaces while it can still be corrected and resubmitted in time.
- Track date-of-service to claim-submitted. Measure the gap for every trip. If claims routinely sit for days before submission, that lag is where late denials come from.
- Watch AR aging weekly. A weekly look at accounts receivable aging catches claims drifting toward a deadline before they cross it.
- Keep proof of timely submission. Save the clearinghouse acceptance report or portal confirmation for every claim. If you ever need a timely-filing override, that proof is the only thing that makes a resubmission possible.
Fast submission does more than beat the clock. Claims filed within a day or two tend to be more complete and generate fewer denials, because the trip details are still fresh. Well-run NEMT billing operations treat submitting clean claims within 24 to 48 hours and holding clean-claim rates above 95% as operating targets — a discipline that compounds, not a guarantee. Operators who want that consistency without staffing for it can price a dedicated team on our pricing page or contact us directly.
Frequently asked questions
What happens if I miss the NEMT timely filing deadline?
The claim is denied and, in most cases, there is no payment for that trip — you absorb the full cost of a ride you already provided. Some states allow a timely-filing override when you can prove the delay was outside your control, but overrides are the exception. Treat the deadline as firm and file long before it.
Which state has the shortest NEMT filing window?
Among fee-for-service Medicaid programs, Texas at 95 days from the date of service is one of the tightest, and New York's eMedNY publishes a 90-day standard. Deadlines change and broker or managed-care windows are often shorter still, so always confirm your current state manual and contract.
Do brokers have their own filing deadlines?
Yes. When a broker or managed-care plan pays the claim, the contract sets the deadline, and it is usually shorter than the state fee-for-service rule. File to whichever window is tighter, and confirm the exact number in your current broker or plan contract.
How fast should I submit NEMT claims?
Submit within 24 to 48 hours of trip completion. Fast submission keeps you far inside every filing window, surfaces errors while they can still be fixed, and shortens the time from date of service to collected cash.
Can a denied late claim be resubmitted?
Only if the payer allows a timely-filing override, and only when you can show proof of the original timely submission — a clearinghouse acceptance report or portal confirmation. Keep that documentation for every claim, because without it a late denial is usually final. The same avoidable errors show up in our roundup of common NEMT billing mistakes.
