What the insurer actually argued

Denials fall into different categories, and they don’t succeed equally — so the reason on your letter changes how you should answer it.

Medical Necessity
The plan said the care wasn’t medically necessary. The most common fight, and the most winnable.

10%
Experimental/Investigational
The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument.

Where the denial was overturned

A 53-year-old male enrollee requested authorization and coverage of external counterpulsation therapy. The Health Plan denied the request indicating that the requested therapy is experimental for treatment of the enrollee’s congestive heart failure.Three physician reviewers performed an experimental/investigational Independent Medical Review. Two of the three physician reviewers concluded that the requested therapy is likely to be more beneficial for treatment of the enrollee's medical condition than any available standard therapy. One of the three physician reviewers concluded that the requested therapy is not likely to be more beneficial for treatment of the enrollee's medical condition than any available standard therapy.

A 58-year-old female enrollee requested the wearable cardioverter defibrillator for medical treatment of her congestive heart failure. Findings: The physician reviewer found that given this patient’s presentation with severe cardiomyopathy and recurrent episodes of sustained ventricular tachycardia, it was reasonable to place the wearable cardioverter defibrillator while awaiting the recovery of the heart function. The efficacy of the wearable cardioverter defibrillator has been tested for induced ventricular tachyarrhythmias as well as for spontaneous events in clinical trials and post-market study. Consistent with these findings, the wearable cardioverter defibrillator was medically necessary for treatment of this patient’s medical condition.

Where the denial was upheld

Worth reading too — these show what an appeal has to overcome.
Physician 1: The patient is a 54-year-old male who has requested authorization and coverage for a home defibrillator kit. Review of the submitted medical documentation indicates the patient has a history of dilated cardiomyopathy. His most recent echocardiogram demonstrated left ventricular enlargement, moderate to severe, with global hypokinesis and an estimated ejection fraction of 20-25%. The patient’s physician has recommended the patient undergo implantation of an automatic internal cardioverter defibrillator (AICD). The patient wishes to receive a home defibrillator kit. The Health Plan has denied this request indicating that the requested device is considered investigational for treatment of the patient’s condition. The Health Plan’s denial should be upheld. The provided documentation indicates the patient has not had a recent cardiology evaluation.
Experimental/Investigational · 2005 · IMR EI05-4223
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for the Zoll LifeVest (K0606). The Health Plan has denied this request indicating that the equipment at issue was not medically necessary for treatment of the enrollee who has a history of congestive heart failure. Findings: Current medical literature does not support the equipment at issue in this clinical setting. At this time, prophylactic wearable external defibrillator would be indicated only if accepted criteria for an implantable defibrillator were met and an implantable defibrillator could not be placed, needed to be significantly delayed or require explantation. Based on the records provided, the patient had a newly recognized cardiomyopathy with an ejection fraction of 20-25% that subsequently improved on repeat echocardiograms.

These are California outcomes — every state runs an equivalent external review, but the rates here are California’s. Excerpts are quoted verbatim from the public record and describe this condition generally, not any individual case.

How to use this in your appeal

These outcomes come from California’s external review program — an independent physician panel whose decision binds the insurer. Every state has an equivalent, and internal appeals succeed even more often. If your care for chf was denied, the published record says the denial is worth fighting.
