Does Medicare Cover Multiple Sclerosis Treatment in 2026?
Yes — does Medicare cover multiple sclerosis treatment in 2026 — comprehensively across all treatment categories. Medicare Part B covers physician and neurologist visits, MRI imaging, and most importantly the IV infusion disease-modifying therapies that are increasingly the standard of care for MS. Medicare Part D covers oral disease-modifying therapies and symptomatic medications. Medicare Part B also covers physical therapy, occupational therapy, and speech therapy which are essential components of MS rehabilitation.
Multiple sclerosis treatment has been transformed over the past two decades with the development of highly effective disease-modifying therapies (DMTs) that slow disease progression and reduce relapses. Medicare covers the full range of these DMTs — from older injectable medications through modern high-efficacy oral and infusion therapies. Understanding does Medicare cover multiple sclerosis treatment across all these options helps MS patients access the most appropriate therapy for their disease without financial barriers.
Does Medicare Cover MS Disease-Modifying Therapies?
Does Medicare cover MS disease-modifying therapies in 2026? Yes — and the coverage pathway depends on whether the DMT is administered by infusion (Part B) or taken as an oral medication or self-injection (Part D).
IV Infusion MS DMTs — Part B
The highest-efficacy MS disease-modifying therapies are administered by IV infusion in clinical settings — covered under Medicare Part B at 80% after the $257 annual Part B deductible:
Ocrelizumab (Ocrevus) — one of the most important and most used high-efficacy MS DMTs. Ocrevus is FDA-approved for both relapsing MS and primary progressive MS — the only approved therapy for PPMS. Administered as IV infusions every 6 months. Medicare Part B covers Ocrevus at 80% after the deductible.
Medicare-approved amount per Ocrevus infusion — approximately $20,000 to $25,000. Your 20% coinsurance without supplement — approximately $4,000 to $5,000 per infusion. Two infusions per year — your annual coinsurance without supplement — approximately $8,000 to $10,000.
With Medigap Plan G — Ocrevus costs $0 after the $257 annual Part B deductible — saving $8,000 to $10,000 per year. This is one of the most significant Plan G financial benefits for any Medicare condition.
Natalizumab (Tysabri) — high-efficacy IV infusion given monthly — covered Part B at 80%. Medicare-approved approximately $7,000 to $9,000 per infusion monthly. Your 20% — approximately $1,400 to $1,800 per infusion — $16,800 to $21,600 annually without supplement. With Medigap Plan G — $0 after annual deductible — saving $16,800 to $21,600 per year.
Alemtuzumab (Lemtrada) — high-efficacy IV infusion given in annual courses — covered Part B.
Mitoxantrone — IV infusion used for aggressive MS — covered Part B.
Self-Injectable MS DMTs — Part D
Older injectable MS medications self-administered at home — covered under Medicare Part D:
- Interferon beta-1a (Avonex, Rebif) — covered Part D — $35 monthly insulin-class cap does NOT apply — subject to formulary tier and $2,000 annual maximum
- Interferon beta-1b (Betaseron, Extavia) — covered Part D
- Glatiramer acetate (Copaxone, Glatopa generic) — covered Part D — generic available reduces cost significantly
- Peginterferon beta-1a (Plegridy) — covered Part D
Self-Injectable High-Efficacy DMT — Part D
Ofatumumab (Kesimpta) — a subcutaneous self-injection B-cell depleting therapy — covered Part D. Unlike Ocrevus which requires IV infusion Kesimpta can be self-injected monthly at home — covered under Part D subject to $2,000 annual maximum.
Does Medicare Cover Oral MS Medications?
Does Medicare cover oral MS disease-modifying therapies in 2026? Yes — Medicare Part D covers all FDA-approved oral MS medications — and anticonvulsants are a protected drug class which means MS-related oral medications that fall into protected categories must be covered.
Oral MS DMTs — Part D
- Dimethyl fumarate (Tecfidera, Vumerity) — covered Part D
- Diroximel fumarate (Vumerity) — covered Part D
- Monomethyl fumarate (Bafiertam) — covered Part D

- Siponimod (Mayzent) — covered Part D — for secondary progressive MS
- Ozanimod (Zeposia) — covered Part D
- Ponesimod (Ponvory) — covered Part D
- Teriflunomide (Aubagio) — covered Part D

MS MRI Coverage
Brain MRI — covered for MS diagnosis and monitoring disease activity and new lesions. Spinal cord MRI — covered for evaluating MS lesions affecting the spine. MRI with gadolinium contrast — covered for detecting active inflammation.
Most MS patients require annual or more frequent MRI monitoring. The recurring cost of MRI monitoring makes Medigap Plan G particularly valuable for MS patients — eliminating the 20% coinsurance on each MRI study throughout the year.

Does Medicare cover home health care for homebound MS patients in 2026? Yes — Medicare covers home physical therapy, occupational therapy, speech therapy, skilled nursing, and social work at 100% for homebound MS patients.
