If you've received a Form NF-10 denial from a New York auto insurer, the claim isn't dead — it's just been moved to the next stage. Most no-fault denials are reversible, but only if you respond quickly and on the right grounds.
Step 1: Read the NF-10 carefully
The NF-10 lists the specific reason for the denial. That reason is the only ground the carrier can defend at arbitration — they can't change it later. Identify the reason exactly: 'lack of medical necessity per IME of [date]', 'failure to attend IME', 'late notice', 'services not covered', etc.
If the denial form is vague or doesn't state a clear basis, that itself is a defense — a defective denial can be invalidated.
The 4 most common denial reasons
1. Lack of medical necessity — based on an adverse IME or peer review. The most common denial. Beatable with a strong written rebuttal from the treating provider.
2. Late notice — claim not filed within 30 days, or bills not submitted within 45 days. Sometimes beatable with proof of reasonable justification.
3. Failure to attend an IME — two consecutive missed IMEs end the claim. Reschedule before the second miss if humanly possible.
4. Services not covered — the carrier argues the treatment doesn't fall under no-fault. Often a coding or documentation issue that can be fixed and re-billed.
Step 2: Build your rebuttal
For medical-necessity denials, the rebuttal is everything. It should: (a) quote specific findings from the IME or peer review, (b) point out internal contradictions or unsupported conclusions, (c) attach a written response from the treating provider addressing each criticism, and (d) cite the medical records that support continued treatment.
A rebuttal isn't optional — without one, the arbitrator only hears the carrier's side of the medical story.
Step 3: File for AAA arbitration
Submit an AR-1 request for arbitration on the Forthright platform. Include every disputed bill, every supporting record, the denial form, and your rebuttal package. There's no rigid filing deadline (no-fault claims don't have a statute of limitations in the traditional sense), but the longer you wait, the harder evidence is to assemble.
Most cases are decided on the papers within a few months. If you win, the carrier pays the bill plus statutory interest (currently 2% per month, simple) and your attorney's fees per the no-fault fee schedule.
Step 4: Don't accept the first answer
Carriers deny aggressively because most claimants give up. The ones who push back through arbitration win at rates well above 50% when the file is properly prepared. The cost of preparing a strong arbitration file is small relative to the recovery, and the carrier covers fees if you prevail.
Frequently Asked Questions
What should I do if my no-fault claim is denied in New York?

How long do I have to challenge a no-fault denial in NY?
