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.

66.7%
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

Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement for electromyography (EMG). The records indicate that the patient presents with a history of Ehlers-Danlos syndrome, migraine headache, and cervical dystonia. A record review showed that the patient complains of neck pain radiating to the left arm with numbness and tingling in the left more than the right arm. The patient indicated that she was injured by a dog, and started having weakness, numbness, and tingling sensation in the left arm thereafter. The provider noted that the patient’s presentation was consistent with sciatica and tarsal tunnel syndrome of both lower extremities.

Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for placement of a port catheter for central venous access. A significant proportion of patients with postural orthostatic tachycardia syndrome (POTS) require non-oral nutrition and/or hydration, especially those presenting with nausea and vomiting, as is the case with this patient. Patients with POTS may also have several gastrointestinal symptoms, especially those with connective tissue diseases such as Ehlers-Danlos syndrome (EDS), which this patient has also been diagnosed with. Parenteral nutrition and hydration may be indicated in patients with POTS when there is nausea and vomiting. Parenteral nutrition is appropriate in patients with malnutrition who are unable to maintain nutritional status despite enteral means, or who are not able to be fed orally or enterally for various reasons.

Where the denial was upheld

Worth reading too — these show what an appeal has to overcome.
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for IVIG therapy.The submitted clinical documentation does not support that IVIG therapy is medically necessary for the patient. There are no visit notes demonstrating how diagnoses of mast cell activation syndrome (MCAS), Ehlers-Danlos syndrome or postural hypotension syndrome (POTS) were made. All of the patient’s submitted mast cell studies were normal and the records fail to demonstrate evidence of mast cell activation syndrome.
Medical Necessity · 2019 · IMR MN19-31282
Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for (1) hydrocodone 10 mg, four times a day, or (2) hydrocodone 10 mg, three times a day. Findings: The physician reviewer found that when to initiate or continue opioids for chronic pain, Dowell and colleagues report, “Nonpharmacologic therapy and nonopioid pharmacologic therapy are preferred for chronic pain. Clinicians should consider opioid therapy only if expected benefits for both pain and function are anticipated to outweigh risks to the patient.
