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.
Reason givenDecisionsOverturned
Medical Necessity
The plan said the care wasn’t medically necessary. The most common fight, and the most winnable.
36
25%
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

Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for (1) surgery to remove excessive skin from bilateral arms and (2) surgery to remove excessive skin from bilateral thighs. Findings: The physician reviewer found that The submitted documentation supports the medical necessity of a portion of the requested services. According to the American Society of Plastic Surgeons, when surgery to remove extensive skin redundancy and fat folds is performed solely to enhance a patient’s appearance in the absence of any signs or symptoms of functional abnormalities, the procedure should be considered cosmetic in nature.

Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for endoscopic revision of gastrojejunal anastomosis (CPT code 43999) and anesthesia (CPT code 00731). Thompson and colleagues studied the safety and efficacy of transoral outlet reduction for the treatment of weight regain in Roux-en-Y gastric bypass patients. Weight loss or stabilization was achieved in 96% of patients six months after outlet reduction. Researchers noted, “When implemented as part of a multidisciplinary intervention, transoral outlet reduction using endolumenal suturing is safe, reproducible, and effective approach to manage weight recidivism after Roux-en-Y gastric bypass surgery.” In this case, the patient has coronary artery disease requiring intervention at a young age.
