Providers generally must submit medical bills within 45 days after the services are rendered. The NF-3 form is used for reporting healthcare provider treatment and related information, while reimbursement is governed by applicable New York no-fault fee schedules, documentation requirements, and insurance regulations.

What Is New York No-Fault Billing?
New York no-fault billing is the process of submitting medical claims to the appropriate automobile insurer for eligible healthcare services resulting from a motor vehicle accident.
New York’s no-fault system is intended to provide benefits for covered accident-related medical expenses and certain other economic losses, regardless of who caused the accident, subject to the requirements of New York law and the applicable policy.
For healthcare providers, the process involves more than submitting a medical bill. Billing teams must verify insurance information, obtain relevant claim details, document treatment, complete the appropriate forms, apply the correct billing codes, and meet applicable filing deadlines.
How Does No-Fault Insurance Work in New York?
Under New York’s no-fault system, eligible injured individuals generally seek covered medical expense benefits through the applicable no-fault insurer, often the insurer of the vehicle involved in the accident.
The insurer evaluates the claim based on coverage, eligibility, medical documentation, applicable billing rules, and other requirements.
For providers, the typical workflow includes:
- Obtain the patient’s accident and insurance information.
- Confirm the applicable no-fault insurer and claim number.
- Gather the required medical and billing documentation.
- Submit the appropriate claim forms and medical bills.
- Monitor the claim for payment, requests for information, or denial notices.
Providers should verify the applicable coverage and claim requirements rather than assume that every service following an accident will be reimbursed.
Who Pays Medical Bills After a No-Fault Accident?
Generally, the applicable no-fault insurer is the first source of payment for eligible accident-related medical expenses within the coverage available under the policy and applicable law.
However, the exact payment responsibility depends on the circumstances, including coverage, eligibility, available benefits, medical necessity, and compliance with claim procedures.
Healthcare providers should establish the correct billing pathway before submitting claims. They should also review the applicable rules before transferring any unpaid balance to a patient.
For official information about New York’s no-fault system, consult the New York State Department of Financial Services (DFS).
What Types of Medical Services May Be Covered?
Depending on eligibility, coverage, and applicable requirements, no-fault medical claims may include services such as:
- Physician consultations and examinations.
- Physical therapy and rehabilitation.
- Chiropractic treatment.
- Diagnostic testing and imaging.
- Hospital and outpatient services.
- Other eligible healthcare services related to the accident.
Coverage does not automatically guarantee payment. The insurer may evaluate whether the service is related to the accident, properly documented, eligible for reimbursement, and billed according to applicable requirements.
What Is the NF-3 Form in New York No-Fault Billing?
The NF-3 form, commonly referred to as the Verification of Treatment by Attending Physician or Other Provider of Health Service, is a New York no-fault form used by healthcare providers to report treatment and related information for an injured patient.
It helps the insurer evaluate the provider’s claim and the healthcare services associated with the accident.
Providers should use the applicable official form and follow the insurer’s submission instructions.
What Information Does the NF-3 Form Require?
The NF-3 form requests information relevant to the patient’s treatment and the provider’s claim. Depending on the form version and circumstances, this may include:
- Patient identification and contact information.
- Accident-related information.
- Diagnosis and relevant medical history.
- Details about the treatment provided.
- Information about the patient’s condition and treatment plan.
- Provider identification and billing information.
- Applicable payment authorization or assignment-of-benefits information.
Ensure that the information is complete, accurate, and consistent with the medical record and supporting billing documents.
Missing or inconsistent details may lead to additional requests, processing delays, or disputes.
How to Complete and Submit an NF-3 Form
Follow these practical steps when preparing the form.
Step 1: Verify the patient’s information.
Confirm the patient’s identity, accident date, and relevant insurance information.
Step 2: Confirm the no-fault claim details.
Obtain the insurer’s name, claim number, and any other required information. Verify the appropriate submission destination.
Step 3: Document the treatment.
Ensure the diagnosis, treatment information, and other required details are supported by the medical record.
Step 4: Review provider and payment information.
Complete the applicable provider information and any relevant payment authorization or assignment-of-benefits sections according to the patient’s and provider’s actual arrangements.
Step 5: Check the completed form.
Review the form for missing fields, inconsistencies, and required signatures.
Step 6: Submit and retain documentation.
Follow the insurer’s accepted submission method and retain a copy of the completed form and evidence of submission.
The NF-3 form is not a substitute for every medical bill or supporting document that may be required. Providers must follow the insurer’s instructions for submitting the complete claim.

Use the official version and verify that the form is appropriate for the claim being submitted. Check with the insurer if additional forms or supporting documentation are required.
NF-3 vs. NF-2: What’s the Difference?
The NF-3 and NF-2 forms serve different purposes within New York’s no-fault process.
| Form | Primary purpose |
| NF-2 | Application for motor vehicle no-fault benefits, generally completed by the injured person or applicant. |
| NF-3 | Verification of treatment by an attending physician or other healthcare provider. |
The NF-2 generally relates to the injured person’s application for benefits, while the NF-3 supports the provider’s reporting of treatment.
Providers should not assume that submitting an NF-3 alone satisfies every requirement associated with the underlying no-fault claim.
Understanding the New York No-Fault 45-Day Rule
The no-fault 45-day rule is a key billing deadline for healthcare providers in New York.
Under the applicable no-fault regulations, healthcare providers generally must submit bills for health services within 45 days after the services are rendered. The relevant rules also address circumstances in which a late submission may be excused.
Timely submission is important because a late bill may be disputed or denied unless an applicable exception or justification is established.
When Does the 45-Day Billing Deadline Start?
The general deadline is measured from the date the health services were rendered.
For example, if a provider renders a service on March 1, the provider should calculate the applicable 45-day deadline from that service date and submit the bill within the required period.
For claims involving multiple dates of service, billing teams should track each applicable deadline rather than rely on a single date for the entire account.
A practical way to manage the deadline is to record:
- Date of service.
- Date the claim was prepared.
- Date the claim was submitted.
- Submission confirmation or tracking information.
- Any payer response or request for additional information.
These records can help demonstrate timely submission if a dispute arises.
What Happens If a Medical Bill Is Submitted Late?
Late submission may expose the claim to a timeliness dispute or denial. Providers should not assume that an insurer will accept a late bill automatically.
Under New York’s no-fault regulations, a late submission may be excused when the provider establishes a legally sufficient justification, as applicable. Whether the circumstances qualify depends on the facts and governing rules.
If a bill is late, the provider should:
- Identify the reason for the delay.
- Gather records supporting the explanation.
- Review the applicable regulatory requirements and insurer instructions.
- Submit the bill with the necessary explanation or documentation.
- Monitor the insurer’s determination and any available dispute options.
A justification should be factual and supported by documentation. An explanation alone does not guarantee that a late bill will be accepted.
How Is the 45-Day Billing Rule Different From the 30-Day Notice Rule?
These are separate deadlines and should not be confused.
| Requirement | General deadline | Purpose |
| Written notice of claim | Generally within 30 days after the accident, subject to applicable exceptions | Notifies the insurer of the claim. |
| Healthcare provider’s medical bill | Generally within 45 days after services are rendered | Submits the provider’s bill for reimbursement. |
The 30-day notice requirement and the 45-day medical-bill deadline apply to different parts of the no-fault process.
Meeting one deadline does not automatically satisfy the other. Providers should verify that the underlying claim has been reported appropriately and that each bill is submitted within the applicable period.
For official guidance, consult the New York DFS no-fault FAQs.
How Does the NY No-Fault Fee Schedule Work?
The NY no-fault fee schedule establishes applicable reimbursement limits for many healthcare services associated with eligible motor vehicle accident claims.
New York Insurance Law § 5108 and the applicable regulations govern charges for covered health services. New York has adopted Workers’ Compensation fee schedules for many services, with modifications and separate rules for certain other services.
The applicable reimbursement method depends on the type of service, provider, date of service, and governing fee schedule.
Which Fee Schedules Apply to No-Fault Medical Billing?
Different services may be subject to different reimbursement rules.
Examples include:
- Professional healthcare services governed by applicable Workers’ Compensation fee schedules.
- Physical therapy, occupational therapy, chiropractic, and other services governed by their applicable schedules and rules.
- Inpatient hospital services subject to applicable hospital reimbursement methodologies.
- Certain services without a specific adopted schedule, for which other regulatory provisions may apply.
Providers should identify the correct schedule for the service being billed instead of assuming that a single rate applies to every no-fault claim.
The New York DFS Regulation 83 and No-Fault Fee Schedule FAQs provide official information about applicable schedules and reimbursement requirements.
How Are Reimbursement Amounts Determined?
Reimbursement may depend on several factors:
- Service performed: The actual procedure or healthcare service provided.
- Provider type: The provider’s license and applicable billing category.
- Applicable fee schedule: The schedule and rules governing the service.
- Date of service: The rules and schedule provisions applicable on that date.
- Claim documentation: Whether the submitted information supports the billed service.
- Other applicable requirements: Coverage, eligibility, and regulatory provisions affecting reimbursement.
Billing teams should validate procedure codes and charges against the applicable fee schedule before submitting claims.
What Happens When a Provider Bills Above the Permitted Fee?
A billed charge that exceeds the applicable permitted amount may be reduced or disputed by the insurer.
Providers should review the fee schedule, relevant coding rules, and any explanation provided by the insurer to determine whether the adjustment is correct.
If the provider believes the insurer applied the wrong schedule or calculated reimbursement incorrectly, the provider should gather supporting documentation and follow the applicable dispute procedures.
Exceptions may exist for certain circumstances under the governing regulations, but providers should not assume that billing above the scheduled amount will result in additional reimbursement.
What Should Providers Do About Underpayments?
When a payment appears lower than expected, compare the remittance advice with the original claim and applicable fee schedule.
Review:
- The billed procedure and units.
- The provider’s applicable fee schedule.
- The insurer’s calculation and adjustment codes.
- Any reductions or documentation-related explanations.
- Whether the payment reflects the correct service and date.
If the payment appears incorrect, contact the insurer or follow the appropriate dispute process. Keep a record of the amount in dispute, supporting calculations, submission dates, and payer responses.
How to Bill No-Fault Insurance in New York: Step-by-Step
A consistent workflow helps healthcare providers manage no-fault claims while reducing avoidable errors and administrative delays.
Step 1: Verify Accident and Insurance Information
Collect the patient’s relevant details, accident date, insurer information, and no-fault claim number.
Confirm that the claim is associated with the correct insurer and that the provider has the information required to submit the bill.
Step 2: Obtain Required Claim Information and Documentation
Identify which forms, records, and supporting details the insurer requires.
Depending on the claim, this may include the NF-3, medical records, accident information, and other documentation needed to evaluate the service.
Confirm that the information is complete before proceeding.
Step 3: Document Treatment and Select Appropriate Codes
Ensure the medical record supports the services provided, diagnoses, and billed procedures.
Assign the appropriate codes according to the documentation and applicable coding rules. Avoid selecting codes solely to obtain a particular reimbursement amount.
Step 4: Complete the NF-3 Form and Prepare the Medical Bill
Complete the NF-3 where applicable and prepare the medical bill according to the insurer’s instructions.
Verify the patient information, claim number, provider details, dates of service, procedure codes, charges, and required supporting documents.
Step 5: Submit the Claim Within the Applicable Deadline
Submit the bill within the generally applicable 45-day period after the services are rendered.
Use the insurer’s accepted submission channel and retain evidence of when the claim was sent.
Step 6: Track the Claim and Follow Up
Monitor the claim for receipt, processing, payment, requests for information, or denial.
If the insurer requests additional documentation, respond promptly and retain records of the response.
If a claim is denied or underpaid, investigate the reason and determine whether correction, additional documentation, or a formal dispute is appropriate.
Common NY No-Fault Billing Errors and How to Avoid Them
Even when a provider delivers appropriate care, billing mistakes can create unnecessary delays or disputes.
Missing or Incomplete NF-3 Information
Incomplete forms may lead to requests for clarification or processing delays.
How to avoid it: Use a standardized checklist to verify required fields, signatures, claim details, and supporting documentation before submission.
Late Medical Bill Submission
Missing the applicable 45-day deadline can create a timeliness dispute.
How to avoid it: Maintain a centralized deadline tracker, assign responsibility for claim submission, and prioritize bills approaching their deadlines.
Incorrect Coding or Fee Schedule Application
Using the wrong code, units, or reimbursement schedule can result in adjustments or underpayment.
How to avoid it: Validate procedure codes and charges against the applicable fee schedule and review unusual adjustments.
Missing Documentation or Unanswered Requests
A claim may remain unresolved when the insurer requests additional information and the provider does not respond promptly.
How to avoid it: Monitor payer correspondence, document each request, and assign follow-up deadlines.
Untracked Denials and Underpayments
Denied or underpaid claims may remain unresolved when they are not assigned to a staff member for follow-up.
How to avoid it: Categorize denial reasons, track outstanding balances, and establish a process for investigating and escalating unresolved claims.
How to Manage No-Fault Denials and Unpaid Claims
A denial or underpayment should be reviewed systematically rather than treated as an automatic write-off.
Review the Insurer’s Explanation
Identify the stated reason for the adjustment or denial and compare it with the original claim.
Determine whether the issue involves eligibility, documentation, coding, timeliness, fee schedule application, or another requirement.
Correct Billing Errors or Provide Requested Information
If the claim contains an error, make the appropriate correction and follow the insurer’s resubmission process.
If documentation is missing, provide the required information according to the payer’s instructions.
Retain the original claim, corrected submission, and supporting evidence.
Review Disputed Payments and Appeal Options
If the provider believes the claim was submitted correctly but the insurer’s decision is inconsistent with the applicable requirements, investigate the available dispute options.
Depending on the issue, the next step may involve a written dispute, reconsideration, arbitration, or another procedure available under New York’s no-fault framework.
Follow the applicable deadlines and requirements. Not every denial is resolved through the same process.
Track Aging Accounts Receivable
Maintain visibility into unpaid claims and unresolved adjustments.
Prioritize accounts according to deadlines, balance, reason for delay, and available resolution options. Regular follow-up helps prevent valid claims from remaining unresolved simply because no further action was taken.
