Montana statute and program

The Montana Medical Marijuana Program is the operating authority for Montana patient certification. The authoritative legal text is: Montana Code Annotated Title 16 Chapter 12: Marijuana Regulation and Taxation Act. The program portal is at Montana Medical Marijuana Program.

What the evidence says about cannabis and Hepatitis C

Hepatitis C is a bloodborne viral infection that causes inflammation and, untreated, progressive scarring of the liver leading to cirrhosis and hepatocellular carcinoma. Since the introduction of direct-acting antiviral (DAA) therapies in 2014, hepatitis C is now curable in over 95% of patients with an 8-to-12-week oral regimen, displacing the older interferon- and ribavirin-based treatments.

How to qualify in Montana

The Montana Medical Marijuana Program requires the following registration steps for a Hepatitis C patient (or any qualifying diagnosis):

  1. Get certified by a Montana-licensed physician. Under Mont. Code Ann. §50-46-301 et seq. (Montana Marijuana Regulation and Taxation Act, voters approved 2004 and modernized 2021), any Montana-licensed MD, DO, advanced practice registered nurse, or physician assistant authorized to prescribe controlled substances may certify a patient. Qualifying debilitating medical conditions include cancer, glaucoma, HIV/AIDS, MS, epilepsy, intractable nausea, severe chronic pain, cachexia, severe muscle spasms, PTSD, Crohn’s, central nervous system disorders, painful peripheral neuropathy, and admittance to hospice care.
  2. Apply through the Montana DPHHS portal. The patient creates an account in the Montana Department of Public Health and Human Services (DPHHS) Cannabis Control Division registry portal, uploads the physician certification, a Montana driver license or state ID, and a passport-style photograph. Caregivers (called "providers" under Montana law) register separately and pass a state background check.
  3. Pay the $5 state registration fee. The annual Montana medical marijuana registry card fee is $5 — among the lowest in the United States. Patients pay only this nominal state fee plus the physician certification fee. Caregivers pay a separate higher provider licensing fee through the Cannabis Control Division.
  4. Receive the card and purchase from a Montana dispensary. Montana medical marijuana registry cards are typically issued within 5 to 10 business days of complete application. Patients may purchase up to 5 ounces of usable cannabis per month from any of the licensed Montana medical dispensaries and may cultivate up to 4 mature plus 4 seedling plants. Adult-use retail launched January 1, 2022 under HB 701 (2021); medical patients retain the lower 4% medical tax versus the 20% adult-use rate and access to higher-potency products.

ICD-10 code

A certifying physician documenting Hepatitis C for the Montana medical cannabis program will typically record ICD-10 B18.2 or SNOMED-CT 50711007 in the patient's record. The state registry does not itself collect ICD-10 codes in most programs, but the physician's chart is the audit trail if the certification is later reviewed.

Frequently asked questions

Does Montana list Hepatitis C as a qualifying condition for medical cannabis?

No. Montana's qualifying-condition list does not currently include Hepatitis C, and the state's program does not give physicians open-ended discretion to add conditions outside the list. Patients with Hepatitis C in Montana have limited in-state pathways under the medical program as written. Options to verify and pursue include: petitioning the state regulator to add the condition (where the statute permits public petitions); consulting a physician about whether a co-occurring listed condition could support certification; or reviewing whether the state's program is undergoing legislative expansion. Montana program rules change, so verify the current list with the regulator before drawing a final conclusion.

How do I get a Montana medical marijuana card for Hepatitis C?

Because Montana does not currently list Hepatitis C as a qualifying condition, a card for Hepatitis C alone may not be obtainable in-state under the program rules as written. Step one is finding a physician licensed in Montana who is registered with Montana Medical Marijuana Program and willing to evaluate Hepatitis C cases. Step two is collecting your records (diagnosis documentation, treatment history, and the ICD-10 code your physician will use) and bringing them to the certification visit. Step three is the physician's certification through the state registry, followed by the patient registration application, state fee, and waiting period before the card is issued. Montana does not honor out-of-state cards, so the certification process has to originate inside the state. Verify the patient minimum age with the state program before applying. The authoritative source for the current process is the Montana Medical Marijuana Program site at https://dphhs.mt.gov/marijuana; the state updates fees, forms, and physician registration rules periodically.

What does the evidence say about cannabis for Hepatitis C?

For Hepatitis C, evidence is described as insufficient (no high-quality controlled data is available either for or against). The mmjnow condition page for Hepatitis C lays out the current evidence base, including the citations underlying that evidence tier — typically the National Academies of Sciences, Engineering, and Medicine consensus reports, federal agency guidance, and peer-reviewed reviews. Evidence quality is independent of state law: a state can list a condition for which evidence is limited, and a state can decline to list a condition for which evidence is strong. Patients deciding whether to pursue medical cannabis for Hepatitis C should review the underlying evidence (linked on the condition page) and discuss expected benefit, dosing, and risk with a clinician familiar with both Hepatitis C and cannabinoid pharmacology. Cannabis is not a substitute for evidence-based first-line treatments for Hepatitis C; the evidence position above describes whether trial data supports its use, not whether it should replace standard care.
