Where the denial was overturned

Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for Mavyret 100 mg-40 mg, three tablets daily for eight weeks. 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, regardless of fibrosis, should be treated except those with limited life expectancy due to non-liver-related comorbid conditions. This applies to all patients, regardless of fibrosis. The guidelines recommend that non-cirrhotic treatment-naïve genotype 1a patients should be treated with Mavyret three tablets daily for eight weeks. These recommendations are based on multiple randomized clinical trials, and the medication is U.S.
