Why Medicare doesn't pay for marijuana
- Part D covers only FDA-approved drugs. Under federal rules (42 CFR 423.100), a Part D drug must be approved by the FDA and dispensed by prescription. Marijuana bought at a dispensary isn't an FDA-approved drug. Changes in how federal law schedules marijuana don't change that.
- Part B pays for medical services from Medicare providers, not for a state registry card or dispensary products.
- Medigap and Medicare Advantage follow Medicare's coverage, so they don't pay for marijuana either.
Oregon's medical marijuana program
The Oregon Medical Marijuana Program (OMMP) is run by the Oregon Health Authority; since September 1, 2026, it is part of OHA's Medical Cannabis and Psilocybin Section. It issues registry identification cards to patients with a debilitating medical condition defined in Oregon law (ORS 475C.777), such as cancer, glaucoma, severe pain, severe nausea, seizures or PTSD, documented by an attending provider. The program is a state registry, not health insurance, and its fees and dispensary costs are yours to pay. Questions about the card go to OMMP at 971-673-1234.
FDA-approved cannabinoid drugs
| Drug | How Medicare may cover it |
|---|---|
| Dronabinol (Marinol, Syndros) | Part D, if on your plan's formulary |
| Nabilone (Cesamet) | Part D, if on your plan's formulary |
| Cannabidiol (Epidiolex) | Part D, if on your plan's formulary |
Plans may use prior authorization or other rules. In 2026, your yearly out-of-pocket cost for covered Part D drugs is capped at $2,100, and Extra Help can lower costs if your income is limited. Check a plan's formulary for your drugs at PlanMatch.
The CMS hemp product incentive
Since April 1, 2026, CMS has let participants in two Innovation Center models (ACO REACH and the Enhancing Oncology Model) offer eligible hemp-derived products to some patients, with a third model to follow in 2027. A participating physician must provide the product directly. CMS says it is not a Medicare coverage change, Medicare doesn't pay for the products, and patients shouldn't be asked to file a Medicare claim.

Frequently asked questions
Does Medicare cover FDA-approved cannabinoid drugs?
They can be covered like other prescription drugs. Dronabinol, nabilone and the cannabidiol drug Epidiolex are FDA-approved; whether your Part D plan covers one, and with what rules, depends on its formulary.
Did Medicare start covering CBD in 2026?
Not as a Medicare benefit. CMS lets some organizations in certain test models give eligible patients hemp-derived products through a participating physician, and says this is not a Medicare coverage change. You can't buy CBD and bill Medicare.
Can my doctor sign my Oregon medical marijuana paperwork?
Oregon lets attending providers such as MDs, DOs, physician associates, nurse practitioners and naturopathic physicians document a qualifying condition. Medicare doesn't pay for the card, and providers may charge you for the paperwork.
