Background: Rezdiffra (resmetirom) is indicated for treatment of non-cirrhotic metabolic dysfunction-associated steatohepatitis (MASH, formerly NASH) with moderate to advanced liver fibrosis consistent with F2–F3 stages. The policy aligns coverage with specialty prescribing, objective fibrosis confirmation, management of metabolic comorbidities, alcohol consumption limits, and GLP-1 trial/therapy requirements.
Specialty alignment and prescriber requirements: Medication must be prescribed by, or in consultation with, a gastroenterologist or hepatologist, and prior authorization requires documentation of age ≥18 and specialist involvement.
Objective fibrosis confirmation: Baseline confirmation of F2–F3 within the past 6 months is required by ONE of the following: non-invasive liver disease assessment (for example ultrasound-based elastography or magnetic resonance elastography [MRE]) or historical liver biopsy.
Metabolic comorbidity management: Prescriber must document the member has at least three metabolic risk factors managed according to standard of care: central obesity; hypertriglyceridemia; reduced HDL cholesterol; hypertension; and elevated fasting plasma glucose (diabetes or pre-diabetes).
Alcohol limits: Prescriber must document alcohol consumption within allowable thresholds: female < 20 grams/day and male < 30 grams/day. One standard drink is defined as approximately 14 grams of pure alcohol (12 oz beer, 5 oz wine, 1.5 oz distilled spirits).
GLP-1 trial/therapy requirement: If GLP-1 naïve, provide documentation of inadequate response, intolerance, or contraindication to a 6-month trial of Wegovy (semaglutide) for MASH/NASH. If currently on a GLP-1 (e.g., Ozempic, Rybelsus, Trulicity), the member must remain on therapy for 6 months at an FDA‑approved maintenance dose before starting Rezdiffra and submit updated labs/imaging after that period.
Definitions: One standard drink ≈ 14 grams pure alcohol (12 oz beer, 5 oz wine, 1.5 oz distilled spirits). MASH is metabolic dysfunction-associated steatohepatitis (formerly NASH).
