IME Cut Off Not Rebutted: Generic Therapist Affidavit Cannot Defeat the Insurer's IME Findings

Key Takeaways

• An “IME cut off” is an insurer’s denial of all no-fault benefits after its examining doctor concludes the injuries have resolved and further treatment is not medically necessary.
• In Rummel G. Mendoza, D.C., P.C. v Chubb Indem. Ins. Co., the insurer’s timely denial based on an orthopedist’s IME report and follow-up report made out a prima facie defense.
• The treating physical therapist’s affidavit failed because it did not meaningfully address the IME doctor’s contrary findings, including normal cervical and lumbar range of motion results.
• A rebuttal must engage the IME’s specific clinical findings point by point; a generic recitation that treatment was necessary will not raise a triable issue.
• The same “meaningfully address” standard governs peer review (medical necessity) defenses across New York no-fault litigation.

The High Bar for Rebutting an IME Cut Off

In no-fault insurance litigation, healthcare providers must overcome insurance companies’ Independent Medical Examination (IME) reports when challenging treatment denials. This case demonstrates the high burden providers face when an IME concludes that a patient’s injuries have resolved and no further treatment is medically necessary.

When an insurer relies on an IME to deny coverage, the examining doctor’s findings carry significant weight in court proceedings. The provider challenging the denial must present compelling medical evidence that directly addresses and rebuts the IME physician’s specific conclusions. Generic affidavits or statements that fail to engage with the IME’s detailed findings typically prove insufficient to create a genuine dispute for trial.

This principle applies broadly across New York No-Fault Insurance Law cases, where medical necessity reversals require substantial medical evidence to succeed.

The Decision

Rummel G. Mendoza, D.C., P.C. v Chubb Indem. Ins. Co., 2015 NY Slip Op 50900(U)(App. Term 1st Dept. 2015):

” establish that it timely denied the claims based on the independent medical examination (IME) report and follow-up report of its examining orthopedic doctor, which set forth a factual basis and medical rationale for her stated conclusion that the assignor’s injuries were resolved and that there was no need for further physical therapy treatment. In opposition, plaintiff failed to raise a triable issue. The affidavit of plaintiff’s treating physical therapist failed to meaningfully address the contrary findings made by defendant’s examining doctor, including the normal results of the range of motion testing of the assignor’s cervical and lumbar spine”

The Legal Framework: How an IME Cut Off Works

Under New York’s no-fault regulation (11 NYCRR 65), an insurer may require an eligible injured person to attend an independent medical examination. When the IME physician concludes that the injuries have resolved, the carrier may deny all benefits for treatment rendered after the cut-off date on lack of medical necessity grounds — the classic “IME cut off.”

On summary judgment, the insurer’s burden is to show a timely denial supported by an IME report that sets forth a factual basis and medical rationale for the conclusion that further treatment is not medically necessary. Once that showing is made, the burden shifts to the provider, who must come forward with medical evidence rebutting the examiner’s conclusions.

The shorthand courts use — the rebuttal must “meaningfully address” the IME findings — has real teeth. An affidavit that merely restates the treatment rendered, recites the patient’s subjective complaints, or asserts in conclusory fashion that therapy remained necessary does not engage the examiner’s objective findings. In Mendoza, the therapist never confronted the normal range of motion testing of the cervical and lumbar spine, and that omission was fatal. The standard mirrors what courts demand of providers opposing peer review denials: rebut the reviewer’s stated rationale, not a strawman.

Why This Matters for Providers and Carriers

For medical providers, the lesson is that the rebuttal affidavit is not a form document. The treating provider — ideally one with personal knowledge of the patient’s course of treatment — must obtain the IME report, quote or describe its specific findings, and explain with objective clinical support why those findings are wrong or incomplete. Positive objective findings on dates after the IME (quantified range of motion deficits, positive orthopedic tests) are the currency that buys a trial.

For no-fault carriers, Mendoza confirms that a well-drafted IME report is a durable defense. The report should document the objective testing performed, the results, and a stated medical rationale connecting those results to the conclusion that further treatment lacks necessity. A follow-up report addressing later-submitted records, as the examining orthopedist provided here, further insulates the denial.

For claims professionals, timeliness remains the threshold issue: the strongest IME report accomplishes nothing if the denial is not issued within the regulatory timeframe. The cut-off defense is a medical necessity defense, and it must be preserved by a timely denial of claim.

Practice Pointers

• Always obtain and read the actual IME report before drafting opposition; courts notice when the affidavit never mentions the examiner’s findings.
• Match objective testing to objective testing. If the IME reports normal cervical and lumbar range of motion, the rebuttal should set out contrary measurements, when they were taken, and with what instrument or method.
• The affiant matters. An affidavit from the treating therapist or physician who actually examined the patient after the IME date carries more weight than one from a records reviewer.
• Providers litigating a string of post-IME bills should remember that each claim still requires proof of the prima facie case, and carriers should confirm the denial chain for every date of service after the cut-off.

Frequently Asked Questions

What is an IME cut off in a New York no-fault case?

It is the insurer’s termination of no-fault benefits based on an independent medical examination concluding that the patient’s injuries have resolved and that further treatment is not medically necessary. Bills for treatment after the cut-off date are denied on medical necessity grounds.

How does a medical provider rebut an IME cut off?

With medical evidence that meaningfully addresses the IME doctor’s specific findings — for example, post-IME objective testing showing continued deficits — and explains why continued treatment was medically necessary. Conclusory affidavits that ignore the examiner’s findings will not defeat summary judgment.

Does the insurer automatically win if it has an IME report?

No. The carrier must first show a timely denial and an IME report containing a factual basis and medical rationale for its conclusion. Only then does the burden shift to the provider to raise a triable issue with a meaningful rebuttal.
