For medical providers treating car accident patients in New York, payment delays from insurance companies can create serious cash flow problems. Fortunately, New York’s no-fault regulations impose strict timelines on insurers. Understanding the 30-day rule, no-fault NY, verification procedures, and interest penalties can help providers determine when a claim has become overdue and when it may be time to pursue legal action.

 

The 30-Day Rule in New York No-Fault Claims

Under New York’s no-fault regulations, insurance companies generally have 30 calendar days to pay or deny a claim once they receive proper proof of claim and any requested verification.

If the insurer fails to issue payment or a denial within that timeframe, the claim becomes an overdue no-fault claim . Courts frequently enforce this rule and may limit the insurer’s defenses when denials are issued late.

Importantly, insurers cannot withhold undisputed portions of a claim while investigating other parts of the claim. If part of the bill is payable, it must be paid within the 30-day window.

For billing teams and providers, the key question is not simply whether 30 days have passed, but whether the insurer has received complete proof of claim and any verification it properly requested . That determines when the 30-day clock actually begins.

 

Verification Requests and Tolling Letters

Insurance companies can pause, or “toll,” the 30-day payment deadline by requesting additional verification under the no-fault regulations.

Verification requests may include documentation, records, or examinations such as EUOs or IMEs. When properly issued, these requests temporarily stop the payment clock until the requested information is received.

Insurers must follow specific procedures when requesting verification, including:

• Requesting initial verification within 10–15 business days after receiving the claim or application
• Requesting additional verification within 15 business days after receiving prior documentation
• Sending follow-up notices if verification has not been received within 30 days
• Clearly identifying what information is still outstanding and who must provide it

For providers, these verification requests and “tolling letters” are just as important as NF-10 denials. They determine when the 30-day deadline actually begins and when a claim can legally become overdue.

If verification requests are late, defective, or overly broad, those issues may become important arguments in arbitration or litigation.

 

The 2% Per Month Interest Rule

When a claim becomes overdue, New York’s no-fault regulations impose a significant financial penalty on the insurer.

Under the regulations, overdue no-fault benefits accrue interest at 2% per month , calculated using a 30-day month. Key points about 2% per month no-fault interest include:

• The interest rate is simple interest , not compounded
• Interest begins once the claim becomes overdue
• Calculations use a 30-day month rule for determining interest periods
• Interest must be paid if the total exceeds $5

Because the interest rate is relatively high, overdue claims can quickly become much more valuable for providers.

 

Example: Calculating Overdue No-Fault Interest

Consider a simple example.

A medical provider submits a $10,000 no-fault bill , and the insurer receives complete verification on January 1 . The insurer does not request additional verification and makes no payment until July 31 .

Here is how the interest calculation works:

Timeline

• Claim becomes overdue on January 31 (30 days after receipt of proof of claim)
• Interest begins accruing on February 1

Interest calculation

• Monthly interest rate: 2% of $10,000 = $200 per month
• Overdue period: 6 months
• Total interest owed: $200 × 6 = $1,200

In this example, the insurer would owe $10,000 in benefits plus $1,200 in statutory interest .

For practices managing high volumes of no-fault claims, these calculations can significantly affect settlement discussions and litigation strategy.

 

Attorney’s Fees on Overdue No-Fault Claims

New York law also allows medical providers to recover attorney’s fees when they successfully obtain payment of overdue no-fault benefits.

Attorney’s fees are typically governed by regulations that:

• Allow recovery of reasonable attorney’s fees for obtaining overdue benefits
• Often calculate fees as a percentage of the amount recovered
• Apply specific minimum and maximum limits depending on the forum

Importantly, if a claim was not overdue at the time arbitration or litigation began, attorney’s fees may not be available. This makes the timing of the 30-day rule and verification procedures especially important when evaluating legal strategy.

 

When Delayed Claims May Require Legal Action

For medical providers and billing departments, tracking submission dates, verification responses, and insurer communications is critical. These details determine whether a claim has truly become overdue under New York’s no-fault regulations.

When insurers delay payment, issue improper verification requests, or allow the 30-day rule no-fault NY deadline to expire, arbitration or litigation may be necessary to recover the benefits owed, along with overdue no-fault claim interest and attorney’s fees.

Understanding how the timing rules and 2% per month no-fault interest calculations work can significantly help protect the financial health of a medical practice.
