Does your practice know how many days it has to bill after treating an auto accident patient? No-fault insurance filing deadlines change by state, and they apply at several points in the claim. For example, New York generally requires provider bills within 45 days of each date of service, while Florida requires initial care within 14 days of the accident for PIP benefits. Miss a window, and a medically necessary service can go unpaid.
Quick answer: No-fault insurance filing deadlines are state-set time limits for initial treatment, the patient’s notice or application, provider bill submission, and the insurer’s response. They differ from state to state and often run per date of service. So confirm each state’s current rule, capture the accident date and policy state at intake, and bill well before the deadline.
About a dozen states use some form of no-fault coverage, and each sets its own timeline. Insurers routinely deny late bills, and those denials are hard to reverse. This guide explains how the timeline works, which deadlines vary most, and the steps a physician billing team can take to prevent late-filing denials.
What Are No-Fault Insurance Filing Deadlines?
No-fault insurance, often called personal injury protection (PIP), lets an injured person claim medical costs and some lost wages from their own auto insurer, no matter who caused the crash. States commonly listed as no-fault include Florida, Hawaii, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Pennsylvania and Utah. However, a few of them let drivers choose between no-fault and traditional coverage.
Because these claims skip a fault investigation, states set deadlines at several points instead:
- Initial medical treatment or evaluation
- The patient’s notice of claim or application
- Provider bill submission
- The insurer’s payment, denial or request for more information
How the No-Fault Claim Timeline Works
Knowing the order of events helps your team get ahead of each deadline instead of reacting to it. The exact number of days depends on the state and the policy. In fact, several of these steps carry their own no-fault insurance filing deadlines.
For example, in New York the patient generally must give written notice within 30 days of the accident, and providers must submit bills within 45 days of each service. The insurer then generally has 30 days from receiving proof of claim to pay or deny. Other states use different numbers, so never apply one state’s limits to another.
State-Specific No-Fault Filing Deadlines
These deadlines are set state by state. As a result, a practice that treats patients from several states needs separate tracking for each one.
Why One Standard Does Not Work
A workflow built around one state’s rules will miss deadlines in another. For instance, Florida’s 14-day initial treatment rule has no match in New York, where the key provider limit is 45 days from each date of service.
Building State-Specific Tracking
Your system should flag the right deadline based on the policy and the governing state’s law, not just where your office sits. This matters most near state borders, where patients often carry out-of-state policies. In short, tracking no-fault insurance filing deadlines state by state is the only safe approach.
No-Fault Insurance Filing Deadlines in Four States
The table summarizes general rules in four large no-fault states. Still, statutes, regulations and policy terms change, so confirm current requirements before you rely on any number. Your state insurance regulator, such as the New York Department of Financial Services, publishes the official rules.
| State | Initial treatment window | Provider bill deadline | Patient notice or application |
|---|---|---|---|
| Florida | 14 days from the accident for PIP benefits | Set by statute; confirm the current limit | Prompt notice under the policy terms |
| New York | No fixed statutory window | 45 days from each date of service | 30 days from the accident (NF-2) |
| Michigan | No fixed statutory window | Check the policy and current law | Written notice within 1 year of the accident |
| Pennsylvania | No fixed statutory window | Check the policy and current law | Check the policy and current law |
Provider No-Fault Filing Deadlines
Provider deadlines are different from patient deadlines. In fact, mixing the two up is a common cause of missed filings.
Provider Bill Submission Windows
In New York, providers must generally submit bills within 45 days of the date of service. That limit replaced a longer 180-day window to speed up claims. If an insurer denies a bill as late, it must tell the provider that the delay can be excused with a reasonable justification. Even so, that exception is narrow, so treat 45 days as a hard limit. Among all no-fault insurance filing deadlines, this is the one your billing team controls most directly.
Per-Visit vs. Per-Accident Tracking
In New York and many other systems, the provider deadline runs from each date of service, not from the accident. So a patient in ongoing therapy creates a new deadline with every visit. As a treatment plan stretches over weeks or months, manual tracking becomes more and more error-prone.
Why No-Fault Filing Deadlines Are Strict
No-fault systems were designed to pay medical bills quickly without a long fault fight. Tight deadlines keep that system moving. That is also why insurers enforce them firmly, even when a patient struggled with paperwork during recovery.
Good-Cause Exceptions
Some states allow limited exceptions for good cause, such as a documented inability to file because of the injury itself. However, these exceptions are narrow and need specific proof. They should never replace timely filing.
How to Avoid Denials for Late No-Fault Claims
Most denials tied to no-fault insurance filing deadlines are preventable. The fix starts before treatment does.
- Flag deadlines at intake. First, capture the accident date, the insurer, the claim number and the policy state at the first visit, then set the deadlines in your system.
- Get the assignment of benefits signed. Next, collect the patient’s signed assignment so you can bill the insurer directly.
- Bill before the deadline, not on it. Then submit with a buffer of several days, so a rejection or transmission error still leaves time to resubmit.
- Keep proof of submission. Also save clearinghouse reports, certified mail receipts or portal confirmations for every bill.
- Track the insurer’s clock too. Finally, follow up when an insurer misses its own response limit, since overdue claims may carry interest in some states.

Other Auto Accident Billing Deadlines
Coordinating With Health Insurance Deadlines
When no-fault benefits run out or are denied, claims often move to the patient’s health plan. That plan has its own timely filing limit, which starts its own clock. So track both at once, and send the no-fault denial or exhaustion letter with the health claim.
Documenting the Deadline Trail
Keep a clear record of every deadline met, including submission dates and proof of receipt. This record protects you if a payer later disputes timeliness. It also becomes essential evidence if a late denial goes to appeal or arbitration. After all, proof of timely submission is your best defense when no-fault insurance filing deadlines are disputed. A claims processing team can keep that trail complete for every visit.
Bottom Line on No-Fault Insurance Filing Deadlines
No-fault insurance filing deadlines are strict, state-specific and rarely aligned with each other. A rule that works in one state can cause a denial in another. Insurers enforce these limits no matter how strong the medical case is. Therefore, the practices that avoid late denials build deadline tracking into intake, not into a billing clean-up weeks later.
Frequently Asked Questions
Does the filing deadline clock start on the accident date or the treatment date?
It depends on the state and the specific deadline. Some, like Florida’s 14-day treatment rule, run from the accident date. Others, like New York’s 45-day billing deadline, run from each date of service.
What happens if a no-fault claim is filed late?
The insurer will usually deny it, and these denials are hard to overturn, even when a patient couldn’t manage paperwork during recovery. Some states allow narrow good-cause exceptions, but these need specific proof.
Are no-fault filing deadlines the same in every state?
No. Deadlines vary by state, covering different requirements for initial treatment, patient application, and provider bill submission. A practice treating patients across state lines needs separate tracking for each one.
Does a long-term treatment plan reset the filing deadline?
No. In many states, including New York, the provider billing deadline applies per date of service, not per accident. Each visit in a long treatment plan creates its own separate deadline.
What’s the best way to prevent missed no-fault filing deadlines?
Capture the accident date, applicable state, and correct deadline at intake. Build in a submission buffer before the actual deadline. This stops last-minute issues, like transmission failures or mail delays, from causing a missed filing.
