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.
1,350
81.8%
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 and prospective authorization and coverage for residential treatment center (RTC) services (ASAM 3.5). Per the American Society of Addiction Medicine (ASAM) criteria, this patient meets Level 3.5 criteria for RTC services provided. ASAM criteria focus on six dimensions to determine the appropriate level of care, which includes: (1) intoxication and withdrawal potential; (2) biomedical conditions; (3) emotional, behavioral, and cognitive conditions; (4) readiness to change; (5) relapse, continued use, or continued problem potential; and (6) recovery environment. For dimension 1, the patient had no signs or symptoms of withdrawal after detoxification was completed.

Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for Mavyret for treatment of the enrollee’s chronic hepatitis C virus (HCV), genotype 1a. Findings: The physician reviewer found that according to the most recent joint guidelines issued by the American Association for the Study of Liver Diseases (AASLD) and the Infectious Diseases Society of America (IDSA), all patients with chronic hepatitis C should be treated except those with limited life expectancy due to non-liver-related conditions. The guidelines recommend that all patients should be treated, regardless of fibrosis stage. As ultrasound elastography showed a lack of cirrhosis, thus this patient should be treated as a non-cirrhotic patient. The guidelines recommend that non-cirrhotic treatment naive genotype 1a patients should be treated with Mavyret.

Where the denial was upheld

Worth reading too — these show what an appeal has to overcome.
A 48-year-old male enrollee has requested for an additional 12 weeks of Pegasys and ribavirin for treatment of his hepatitis C virus. Findings: The physician reviewer found that the current approved treatment for hepatitis C is pegylated interferon (Pegasys) plus ribavirin for a total of 48 weeks in genotype-1 patients. Some studies have suggested that a longer treatment period may be warranted in those patients who have a late documented viral clearance while on therapy. Currently, a 12-week time point is used to determine the presence of an early viral response (EVR); however, many studies indicate that a 4-week point may also be useful in predicting a response to 48 weeks of therapy.

The patient is a 57-year-old man with hepatitis C genotype 1 and cirrhosis. He has failed treatment with interferon and ribavirin due to side effects including bone marrow and psychiatric effects. He has a long list of complicating diagnoses including hypertension and cholelithiasis. The patient’s provider has recommended the patient begin treatment with ribavirin monotherapy. The Health Plan has denied authorization and coverage for the requested therapy on the basis it is not medically necessary for treatment of the patient’s medical condition.The issue of treatment failure and the benefit of ongoing therapy with interferon or ribavirin as a method to suppress inflammation has been addressed in the published guidelines of the American Association for the Study of Liver Disease.

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 hepatitis was denied, the published record says the denial is worth fighting.
