For many medical providers in New York, receiving a denial for a no-fault claim can be frustrating and confusing, especially after providing necessary care to patients injured in motor vehicle accidents. These denials often arrive as an NF-10 and may leave providers wondering what went wrong.

 

In reality, insurance companies often rely on a small group of predictable defenses when denying claims. Understanding the most common New York no-fault denial reasons can help providers determine whether a billing correction is needed or whether it may be time to pursue arbitration, litigation, or a medical provider no-fault lawsuit.

 

Failure to Attend an EUO

One common reason claims are denied is failure to attend an Examination Under Oath (EUO) . An EUO allows the insurance company to question a provider or injured party as part of its verification process under New York’s no-fault regulations.

If a provider or patient fails to appear for a properly scheduled EUO, insurers may argue that a required condition of coverage was not satisfied. Courts have recognized that compliance with a properly requested EUO can be treated as a condition precedent to coverage , which may allow the carrier to deny the claim.

 

However, insurers must strictly follow verification procedures when scheduling EUOs. In many disputes, the key question is whether the carrier properly complied with those rules. For example, insurers typically must demonstrate:

• The EUO request was sent within the required verification timelines
• A proper follow-up notice was issued if the first request went unanswered
• The EUO scheduling letters were properly mailed
• The provider or injured party failed to appear for the scheduled examination

If any of these steps were not followed, the denial may be open to challenge.

 

Failure to Appear for an IME

Insurance companies also schedule Independent Medical Examinations (IMEs) to evaluate whether ongoing treatment is medically necessary.

If the injured person repeatedly fails to attend scheduled IMEs, insurers may deny future no-fault benefits based on that noncompliance. This often results in claim denials for treatment rendered after the missed IME appointment.

As with EUOs, insurers must demonstrate that IME notices were properly mailed and scheduled with adequate advance notice. Disputes over these procedural issues frequently arise in arbitration and litigation.

 

Late Billing and the 45-Day Rule

Another frequent reason for denial involves billing deadlines. Under New York’s no-fault regulations, providers generally must submit claims within 45 days of the date services were rendered , absent a reasonable justification for delay.

If a claim is submitted late and no valid explanation is provided, the insurer may deny payment entirely. NF-10 forms commonly cite “untimely billing” as the basis for the denial.

Maintaining organized billing systems and documentation showing when claims were mailed or submitted can be critical when responding to these disputes.

 

Lack of Medical Necessity

Insurers often deny claims based on lack of medical necessity , typically relying on peer review reports or IME reports prepared by physicians retained by the insurance company.

These reports may conclude that continued treatment was unnecessary or unrelated to the accident. When this occurs, the dispute often becomes a question of medical evidence.

Providers may need to present treatment records, physician affidavits, or expert testimony supporting the necessity of the services provided. Because these cases frequently involve competing medical opinions, they are commonly resolved through no-fault arbitration or court proceedings.

 

Fee Schedule Reductions

New York’s no-fault system limits reimbursement based on established medical fee schedules. Insurance carriers often review claims and reduce payments by asserting that charges exceed the allowable schedule.

Disputes may arise over billing practices such as:

• Charges exceeding the applicable no-fault fee schedule
• Incorrect CPT or procedure coding
• “Unbundling” services that should be billed together
• Improper billing methodologies

Careful coding practices and detailed supporting documentation can help providers challenge improper reductions or demonstrate that services were billed correctly under the applicable fee schedule.

 

Mallela and Corporate Practice Defenses

Another defense insurers sometimes raise stems from the Court of Appeals decision in State Farm v. Mallela . Under this doctrine, insurers may deny payment if a medical practice is fraudulently incorporated or effectively owned or controlled by an unlicensed individual.

During these investigations, insurers may request documents such as:

• Corporate formation records
• Ownership agreements
• Management or leasing contracts
• Professional licensing documentation

Because these allegations can affect a provider’s eligibility to bill no-fault benefits at all, they are serious matters that often require legal guidance to address.

 

Policy Exhaustion

Some claims are denied because the injured party’s personal injury protection (PIP) policy limits have been exhausted . In New York, no-fault benefits are typically capped, often at $50,000 per person unless higher coverage limits were selected.

Once those limits are properly exhausted, insurers generally have no further obligation to pay additional no-fault benefits.

However, disputes sometimes arise over whether the policy was truly exhausted when the claim became payable. Reviewing payment histories and claim ledgers may reveal errors in how benefits were allocated or applied.

 

When Repeated Denials Signal a Larger Problem

Occasional claim denials can occur during routine no-fault billing. But when the same issues appear repeatedly, such as EUO or IME nonappearance claims, late billing allegations, fee schedule reductions, or corporate practice investigations, it may signal a broader dispute with the insurer.

In these situations, working with a no-fault collections attorney in NY or a no-fault litigation attorney in NY may be necessary to recover unpaid claims and protect your practice’s revenue.

If your practice keeps asking, “Why was my NF-10 denied?” , it may be time to move beyond billing follow-ups and evaluate your legal options.

If your practice is seeing repeated denials, you may need litigation, not more billing follow-ups.
