Key takeaways

  • Medicare covers medications, therapies, and other services for treating Parkinson’s disease and its symptoms, though beneficiaries should expect some out-of-pocket costs.
  • Different parts of Medicare cover specific aspects of treatment. Part A covers hospital procedures like Duopa pump fitting and deep brain stimulation, while Part B covers outpatient care including occupational, physical, and speech therapy.
  • Medicare Part D covers prescription medications based on the plan’s formulary and tier system, while Medigap can help manage out-of-pocket costs of Original Medicare.

Parkinson’s disease can come with a wide range of motor and nonmotor symptoms. The symptoms of this condition can be different for different people.

Since it’s a progressive disease, symptoms can change over time. Medicare covers a range of different treatments, medications, and services that you may need to manage Parkinson’s disease throughout your life.

Part A is hospital insurance. The procedure to fit a Duopa pump or begin deep brain stimulation typically occurs in a hospital, so Part A will cover the care you receive during an inpatient stay.

Part A may also cover limited home healthcare services, nursing facility stays, and inpatient rehabilitation services after your procedure.

Here are the basic costs for Part A in 2025:

  • $285 to $518 monthly premium, if you have one
  • $1,676 deductible for each benefit period (a person could have multiple benefit periods in a single calendar year)
  • 20% of all Medicare-approved costs during your stay
  • $0 coinsurance for days 1 to 60 of treatment after you pay your deductible
  • $419 coinsurance per day for days 61 to 90 of treatment
  • $838 coinsurance per day for days 91 to 150 of treatment while using your 60 lifetime reserve days
  • 100% of the treatment costs for days 151+

A Medigap plan can help cover the out-of-pocket costs of Original Medicare, including the Part A coinsurance.

Part B is medical insurance. It covers outpatient care, including doctor visits to monitor or adjust your durable medical equipment (DME) and medically necessary equipment upgrades or replacements.

Part B also covers a variety of therapies related to Parkinson’s disease, including:

Here are the basic costs for Part B in 2025:

  • $185 monthly premium, if you have one
  • $257 deductible
  • 20% of all Medicare-approved costs during your treatment
  • any copayment or coinsurance fees

Part C, or Medicare Advantage, bundles hospital and medical insurance with prescription drug coverage (Part D).

Costs vary depending on the plan and provider you choose. Each plan has a different premium, deductible, copayment, and coinsurance amount.

Staying within your plan’s “network” of healthcare professionals, pharmacies, and other providers ensures you receive the maximum coverage at the lowest out-of-pocket cost.

Once you pay your plan’s out-of-pocket maximum, your plan will cover 100% of all Medicare-approved costs. Specifics vary by plan, but in 2025, the maximum out-of-pocket cost for covered services under a Part C plan is $9,350.

The amount of coverage each plan provides depends on its formulary and tier system. A formulary is a list of medications the plan covers. Those medications are then divided into groups or tiers, typically based on cost.

Ask your doctors what medications you’ll need, then talk with your plan provider about your coverage to get an estimate of your copay or coinsurance costs.

Medigap, or Medicare supplement insurance, can help you manage out-of-pocket costs associated with parts A and B. This includes premiums, deductibles, copays, and coinsurance costs.

You can only enroll in Medigap if you have an Original Medicare plan. You can’t enroll in Medigap if you have a Part C plan.

Medicare covers medically necessary treatments for Parkinson’s disease, including hospital stays, different types of therapy, and medications.

Your out-of-pocket costs can vary depending on the type of coverage and parts of Medicare you’re enrolled in. Before you start treatment, talk with your plan provider to confirm how much coverage you’ll receive.
