New York No-Fault Medical Bills: Submission, Verification, and Payment Deadlines
A provider operations guide to New York no-fault medical-bill submission, assignments, verification requests, payment or denial timing, and evidence preservation.
Key Takeaways
- A provider operations guide to New York no-fault medical-bill submission, assignments, verification requests, payment or denial timing, and evidence preservation.
- For formal statutory assistance or dispute reviews, refer to the cited resources below.
New York's no-fault billing process is a chain, not a single deadline. A provider can submit a bill within 45 days and still lose time because an assignment is defective, the claim reached the wrong address, a verification request was not routed, or the billing system treated the insurer's 30-day clock as running while relevant verification remained outstanding.
This guide is written for provider and revenue-cycle operations. It summarizes the mandatory personal injury protection endorsement, 11 NYCRR Part 65 claim procedures, and Insurance Law § 5106. It does not resolve whether a particular patient is an eligible injured person, whether a service is medically necessary, or whether a specific denial is enforceable.
The provider timeline at a glance
| Event | General rule | Operational evidence |
|---|---|---|
| Health service rendered | Written proof of claim generally due within 45 days | Service date, bill form, treatment record, transmission proof |
| Insurer receives completed prescribed verification form | Additional verification generally requested within 15 business days | Receipt date, request date, request contents, delivery evidence |
| Insurer receives all relevant requested verification | Payment or denial generally due within 30 calendar days | Completion date, remittance or denial, undisputed payment |
| Verification remains outstanding | Applicant generally has 120 calendar days from the initial request to supply controlled information or written reasonable justification | Initial request, response packet, explanation, follow-up record |
| Valid payment becomes overdue | Insurance Law § 5106 provides 2% monthly interest and may allow a reasonable attorney's fee subject to regulation | Ledger, interest calculation, dispute record |
1. Start with the correct payer and claim identity
Before billing, confirm the insurer, policy or claim number, accident date, injured person's identifying information, and claims-processing address. A claim sent to an incorrect insurer or non-claims address can create a timing dispute. Section 65-3.5 provides a limited receipt rule when a claim reaches the wrong office of the correct insurer, but that rule should not substitute for address validation.
- Preserve the accident report, insurer identification, and claim-assignment communication.
- Record the proper claims-processing address and any approved electronic submission route.
- Link each bill to its date of service, provider, injured person, and accident—not merely an account balance.
- Retain the exact file transmitted and delivery or clearinghouse acceptance evidence.
- Escalate uncertain payer identity early rather than letting the 45-day proof period run.
2. Submit written proof within the 45-day service-date window
The mandatory New York personal injury protection endorsement in 11 NYCRR 65-1.1 requires written proof of a health-service expense as soon as reasonably practicable and, generally, no later than 45 days after the service is rendered. The proof must include full particulars concerning the injuries and treatment received and contemplated. The regulation permits an exception when written proof gives clear and reasonable justification for late submission, but a provider should not treat the exception as routine filing relief.
A rolling-service case creates multiple deadlines. The 45-day period is tied to the date services are rendered, so a treatment series should not be held for one end-of-episode bill if doing so places earlier dates outside the window. Calculate and store a due date for each billable service or claim grouping.
3. Use a valid direct-payment document
Under 11 NYCRR 65-3.11, a provider seeking direct payment generally needs a properly executed authorization to pay benefits or a permitted assignment. The regulation identifies the NF-3, NF-4, NF-5, and prescribed NF-AOB routes and limits changes to the prescribed assignment language. A clinical record or patient financial-responsibility form does not automatically perform the same function.
| Document control | Review question |
|---|---|
| Form selection | Is the provider using the form appropriate to the service and provider type? |
| Execution | Are the required patient and provider fields, signatures, and dates complete? |
| Language integrity | If using NF-AOB or an equivalent, was the assignment language left substantively unchanged? |
| Claim linkage | Can the executed document be tied to this patient, accident, insurer, and billed service? |
| Original request | Can the team produce the original if the insurer makes a compliant written request? |
4. Treat verification as a managed sub-workflow
Section 65-3.5 generally gives the insurer 15 business days after receipt of completed prescribed verification forms to request additional verification needed to establish proof of claim. The request does not have to use a prescribed form. Medical examinations must generally be scheduled within 30 calendar days after receipt of the prescribed verification forms, and examinations under oath or medical examinations must be reasonably convenient under the regulation.
For information within the applicant's control or possession, subdivision 65-3.5(o) generally requires submission within 120 calendar days from the initial request, or written proof providing reasonable justification for noncompliance. The insurer's request must advise of the possible consequence. The provision excludes prescribed NF forms, medical-examination requests, and examination-under-oath requests, so those items should not be collapsed into one generic 120-day queue.
- Date-stamp the initial verification request and preserve the envelope, portal event, fax, or electronic notice.
- Separate requests for records, NF forms, an examination under oath, and a medical examination.
- Assign each item to an owner and calculate the applicable response date.
- Send a complete, indexed response with delivery proof; identify anything not within the provider's possession or control.
- Record when all relevant requested verification was received because that event may start the insurer's 30-day decision period.
5. Calculate the 30-day payment or denial period from completed proof
Insurance Law § 5106 states that first-party benefits become overdue if not paid within 30 days after the claimant supplies proof of the fact and amount of loss. Regulation 65-3.8 expresses the operational rule as 30 calendar days after the insurer receives proof of claim, including all relevant verification requested under section 65-3.5. The insurer must generally pay or deny the claim in whole or in part within that period.
An additional verification request can delay completion of proof; it should not erase the original claim history. Preserve the original bill receipt, the timeliness of the insurer's verification request, every response, and the date proof became complete. If only part of a claim is disputed, section 65-3.8 requires payment of undisputed elements without prejudice.
When a valid claim is overdue, § 5106 provides interest at two percent per month and a reasonable attorney's fee for services needed to secure payment, subject to regulatory limitations. Those remedies are legal consequences, not automatic posting instructions. A claim-level review should confirm proof completion, denial timing, coverage defenses, and any tolling or procedural issue before calculating recovery.
6. Build the evidence packet before a dispute
- Executed authorization or assignment and any insurer request for the original.
- NF-3, NF-4, NF-5, bill, coding detail, and contemporaneous treatment records as applicable.
- Transmission and receipt proof for the initial claim and every verification response.
- All verification, examination, and examination-under-oath notices with response records.
- Explanation of benefits, payment, partial payment, or NF-10 denial.
- A date ledger showing service, submission, receipt, request, response, proof completion, payment, and denial events.
- Written late-submission justification and supporting evidence when applicable.
