How to Find a Doctor Who Can Prescribe Rezdiffra (Resmetirom) Near You [2026 Guide]

Rezdiffra (resmetirom) treats a specific, serious liver condition: noncirrhotic MASH (metabolic dysfunction-associated steatohepatitis) with moderate to advanced liver fibrosis (Stage F2 or F3). Getting a prescription requires a physician who is familiar with MASH diagnosis, liver biopsy interpretation, and the specialty pharmacy system. That means your journey to Rezdiffra starts with finding the right doctor.

This guide helps you understand which specialists prescribe Rezdiffra, how to get a referral, and what to expect from the diagnostic workup.

Who Prescribes Rezdiffra?

Rezdiffra is not a controlled substance and can technically be prescribed by any licensed physician. However, in practice, it is prescribed almost exclusively by specialists who diagnose and manage liver disease, because the drug's indication requires a liver biopsy confirming MASH with F2-F3 fibrosis — a clinical finding that most primary care doctors are not routinely obtaining.

Here are the types of providers who most commonly prescribe Rezdiffra:

Hepatologists: The primary prescribers. Hepatologists specialize in liver disease and are most likely to have established MASH protocols, perform or coordinate liver biopsies, and be familiar with Rezdiffra's prescribing workflow.

Gastroenterologists: Many gastroenterologists manage MASH patients, particularly in areas where hepatology subspecialists are not readily available. Uptake of Rezdiffra prescribing has been growing in GI practices since 2024.

Endocrinologists: Increasingly involved in MASH care, given the condition's strong association with type 2 diabetes, obesity, and metabolic syndrome. Some endocrinologists with liver disease expertise prescribe Rezdiffra.

Primary Care Physicians (PCPs) with hepatology expertise: PCPs who have appropriately worked up patients (with biopsy confirmation) and are comfortable with the specialty pharmacy system. Less common, but occurs in settings with integrated care models.

Nurse Practitioners and Physician Assistants: Advanced practice providers in hepatology or GI practices may prescribe Rezdiffra in states where their scope of practice permits.

How Do I Know If I Need Rezdiffra?

Rezdiffra is specifically indicated for adults with noncirrhotic MASH and Stage F2 or F3 liver fibrosis. To confirm this diagnosis, you will typically need:

Liver biopsy: The gold standard for confirming MASH and fibrosis staging. Required by most insurers for prior authorization.

Noninvasive tests: FIB-4 score, liver stiffness measurement (elastography), and MRI-PDFF can support clinical decision-making and biopsy staging but typically cannot replace biopsy for insurance approval.

Metabolic risk factor assessment: MASH is closely associated with obesity, type 2 diabetes, high blood pressure, and elevated cholesterol. More than 80% of MASH patients are overweight or obese.

How to Find a Hepatologist or Gastroenterologist Near You

Here are the most practical tools for finding a liver specialist in your area:

Ask your PCP for a referral: If your primary care doctor has noted elevated liver enzymes, fatty liver on imaging, or MASH risk factors, ask for a referral to a hepatologist or gastroenterologist. Your PCP likely has a preferred specialist in your network.

AASLD Find a Doctor tool: The American Association for the Study of Liver Diseases (aasld.org) provides a provider directory for finding liver specialists near you.

Your insurance's provider directory: Search for "hepatologist" or "gastroenterologist" in your plan's online provider directory to find in-network specialists.

Academic medical centers and MASH clinics: Large academic centers (such as UCSF, Mayo Clinic, Johns Hopkins, and many others) have dedicated liver disease programs with MASH expertise. If you live near a major medical center, this is often the fastest path to a biopsy and Rezdiffra prescription.

Is Telehealth an Option for Getting Rezdiffra?

Telehealth is growing in hepatology, particularly for follow-up visits and medication management. However, because Rezdiffra requires a liver biopsy for diagnosis and insurance approval, an in-person visit is typically needed at the outset to perform or coordinate the biopsy. After diagnosis is established, some hepatologists may continue management via telehealth for established patients on Rezdiffra.

Some telehealth platforms that connect patients with gastroenterologists or hepatologists may be able to start the workup process and facilitate referrals to in-person biopsy centers if you live in a rural area or cannot easily access a specialist.

What to Expect at Your First Appointment

When you see a hepatologist or gastroenterologist for MASH evaluation, bring the following:

Any prior liver imaging reports (ultrasound, CT, MRI)

Recent blood work (ALT, AST, complete metabolic panel, lipid panel, HbA1c if diabetic)

List of all current medications (especially statins — important for Rezdiffra drug interactions)

Information about your diet, exercise habits, and alcohol use
