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.
517
24.4%
Experimental/Investigational
The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument.

What the reviewers wrote

Excerpts from the independent reviewers’ published findings — the actual reasoning, quoted, not summarised.

Where the denial was overturned

Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement and prospective authorization and coverage for skilled nursing facility (SNF) services, including speech therapy, physical therapy, and occupational therapy. As noted in the medical literature, admission to SNF is appropriate for patients with conditions that require observation, evaluation of treatment plans, and updating of orders by a physician as well as constantly available skilled nursing services. Patients treated in a SNF require skilled nursing services including wound management, tracheostomy care, bowel and bladder training and tube feeding, and administration of intravenous (IV) medications or medications that cannot be self-administered safely.
