2025 Medicare Coverage for Multiple Sclerosis: Costs and Benefits Explained
Discover comprehensive details on what Medicare covers for Multiple Sclerosis (MS) treatments in 2025, including medications, therapies, equipment, and costs to help you manage your condition effectively.
Medicare provides extensive support for individuals diagnosed with multiple sclerosis (MS), covering a variety of treatments through its different parts. However, it’s important to note that experimental therapies are not included in Medicare coverage.
If you or a family member is living with MS and qualifies for Medicare, many essential treatment expenses are covered to ease the financial burden.
Medicare’s coverage includes:
- FDA-approved medications
- Physical and occupational therapy sessions
- Hospital inpatient care
- Doctor consultations
- Necessary surgeries
- Durable medical equipment (DME)
Your specific coverage and out-of-pocket costs depend on your Medicare plan type and the medical necessity of services related to your MS treatment.
Understanding Medicare Parts and Their MS Coverage
Medicare is divided into parts, each offering different coverage that plays a vital role in managing MS effectively.
Part A: Hospital Insurance
Part A covers inpatient hospital stays, skilled nursing facility care, and some home health care. If you are admitted to a hospital for MS-related treatment, Part A will cover therapies and medications administered during your stay.
Part B: Medical Insurance
Part B complements Part A and covers outpatient services such as doctor visits, physical, occupational, and speech therapies, counseling, medical equipment for home use, lab tests, MRIs, and medications administered in a clinical setting.
Part C: Medicare Advantage Plans
Part C plans are offered by private insurers and replace Original Medicare (Parts A and B). These plans cover all services included in Original Medicare and often provide additional benefits like prescription drug coverage. Most require using network providers to maximize benefits.
Part D: Prescription Drug Coverage
Part D supplements Original Medicare by covering prescription medications, including those needed for MS symptom management and disease progression. Each Part D plan has a formulary listing covered drugs, which can influence your medication costs.
Medigap: Medicare Supplement Insurance
Medigap policies help cover out-of-pocket expenses such as deductibles, copayments, and coinsurance that Original Medicare doesn’t fully cover. However, they do not cover services excluded by Medicare.
Covered MS Medications, Services, and Treatments
Medications
FDA-approved MS medications fall into three categories:
- Slowing disease progression: Includes interferon beta-1a (Avonex, Rebif, Plegridy), interferon beta-1b (Betaseron, Extavia), glatiramer acetate (Copaxone), fingolimod (Gilenya), and ocrelizumab (Ocrevus). These can be administered as pills, injections, or infusions.
- Treating relapses: High-dose corticosteroids like methylprednisolone (Solu-Medrol), prednisone (Deltasone), and ACTH (H.P. Acthar Gel) to manage severe flare-ups.
- Symptom management: Medications tailored to address specific symptoms such as bladder and bowel control issues, depression, pain, fatigue, sexual dysfunction, dizziness, and tremors.
Coverage depends on where medications are received: inpatient treatments fall under Part A, doctor’s office-administered drugs under Part B, and home medications require Part D or a Medicare Advantage plan.
Therapies and Services
Medicare covers medically necessary therapies based on your MS symptoms, including:
- Physical therapy to improve strength, balance, and reduce pain.
- Occupational therapy to assist with daily living activities affected by MS.
- Speech therapy for communication and swallowing difficulties.
- Mental health counseling to address depression and other emotional challenges.
These services are typically covered under Part B, except when received during inpatient care, which is covered by Part A. Medicare Advantage plans also cover these therapies.
Durable Medical Equipment (DME)
Part B covers medically necessary DME used at home, such as canes, walkers, wheelchairs, mobility scooters, raised toilet seats, portable toilets, and pressure-relieving cushions or mattresses.

Expected Costs for MS Treatment Under Medicare
Part A Costs
Most beneficiaries receive Part A premium-free but must pay a deductible of $1,676 in 2025 before coverage begins. Afterward, the first 60 days of inpatient care are fully covered; coinsurance applies from day 61 onward, with increasing daily costs and a lifetime reserve of 60 days.
Part B Costs
Part B requires a monthly premium, standard $185 in 2025, with possible income-related adjustments. There is a $257 deductible, after which you pay 20% coinsurance for most services.
Part C Costs
Costs vary by Medicare Advantage plan and include premiums, deductibles, copays, and coinsurance. Plan availability and pricing differ by location.
Part D Costs
Part D premiums and deductibles vary; the maximum deductible in 2025 is $590. Once out-of-pocket spending reaches $2,000, catastrophic coverage kicks in, eliminating further drug costs for the year.
Medigap Costs
Medigap plans require monthly premiums, generally higher than Parts C or D, but can significantly reduce out-of-pocket expenses by covering coinsurance and deductibles.
Final Thoughts
Multiple sclerosis requires ongoing management involving medications, therapies, and medical equipment. Medicare offers a broad range of coverage options tailored to these needs. Understanding each part’s role helps you optimize your benefits and manage costs effectively in 2025.
Whether through Original Medicare or Medicare Advantage, you can access essential treatments and support to improve your quality of life while managing MS.
