Medicare covers the core medical care most people with Parkinson’s disease rely on, including neurologist visits, physical and occupational therapy, hospitalizations, durable medical equipment such as walkers and wheelchairs, and most Parkinson’s medications through Part D drug plans. Part B typically pays 80 percent of approved outpatient costs after the annual deductible, leaving a 20 percent coinsurance that adds up over years of ongoing therapy and specialist visits. The biggest gap in Original Medicare, according to Medicare.gov, is long-term custodial care — daily help with bathing, dressing, and meals — which Medicare generally does not pay for regardless of diagnosis. Deep brain stimulation surgery falls under Part A for the hospital stay and Part B for programming visits. Most people qualify for Medicare at 65, but people receiving Social Security Disability Insurance for 24 months qualify earlier. Medigap supplemental plans and Medicaid can help fill gaps that Original Medicare leaves. This guide walks through each Part, what it covers for Parkinson’s, and where the common gaps are.

Who is eligible

Most people qualify for Medicare at age 65.
Younger people qualify after receiving Social Security Disability Insurance (SSDI) for 24 months. See Does Parkinson’s Qualify for Social Security Disability?
People with certain conditions (end-stage renal disease, ALS) qualify earlier.

The four parts of Medicare

Part A — Hospital insurance

Covers inpatient hospital care, skilled nursing facility care (short-term, after a qualifying hospital stay), home health care, and hospice. Most people pay no premium because they paid Medicare taxes during their working years.

For Parkinson’s: Hospitalizations for falls, infections (pneumonia, UTI), DBS surgery, and other inpatient care fall under Part A. Skilled nursing facility coverage after a 3-day hospital stay can be important after a fall or surgery.

Part B — Medical insurance

Covers outpatient services — doctor visits, neurology, lab tests, imaging, durable medical equipment, and outpatient therapy. There is a monthly premium and an annual deductible. After the deductible, Medicare typically pays 80% of approved amounts; you pay 20%.

For Parkinson’s, Part B is the workhorse. It covers:

Neurology visits, including movement-disorder specialists.
Primary care.
Physical therapy, occupational therapy, and speech-language therapy when medically necessary.
Mental health visits, including therapy.
DaTscan and other imaging, when ordered.
Durable medical equipment: walkers, canes, hospital beds, wheelchairs, raised toilet seats, commodes (when medically necessary).
Outpatient DBS programming visits.

Outpatient therapy was previously subject to annual caps but is now subject to a “threshold” above which extra documentation is required. Medically necessary therapy can continue.

Part C — Medicare Advantage

Medicare Advantage plans are private plans that bundle Parts A and B, often with Part D drug coverage and extras (sometimes including dental, vision, or hearing). They use a network of providers and may require referrals. Coverage rules and out-of-pocket costs differ from Original Medicare.

For Parkinson’s: If you choose Medicare Advantage, confirm that your neurologist, therapists, and preferred hospitals are in network, and that the drug formulary covers your Parkinson’s medications.

Part D — Prescription drug coverage

Part D plans are private plans that cover prescription drugs. They have premiums, deductibles, copays, and formulary tiers. Plans can be standalone (paired with Original Medicare) or built into a Medicare Advantage plan.

For Parkinson’s: Most Parkinson’s medications — carbidopa-levodopa, dopamine agonists, COMT inhibitors, MAO-B inhibitors, amantadine — are covered by Part D plans, but cost-sharing varies. Some brand-name and newer medications (such as inhaled levodopa, certain extended-release options, pimavanserin) may sit in higher tiers with higher copays. Compare plans every year during open enrollment.

What Medicare generally does not cover

Long-term custodial care (help with bathing, dressing, meals) — even in a nursing facility. This is the biggest gap.
Most adult day care.
Most home modifications like grab bars, ramps, or stair lifts.
Most non-emergency transportation.
Routine dental, vision, and hearing in Original Medicare. Some Medicare Advantage plans include limited coverage.
Out-of-country care (with rare exceptions).
Many fitness, alternative therapy, and complementary care services.

These gaps are why Medicaid, long-term care insurance, Veterans Affairs benefits, and supplemental insurance (Medigap) often matter for people with Parkinson’s as needs increase.

Medigap (Medicare Supplement Insurance)

Medigap plans are private policies that cover some of the out-of-pocket costs Original Medicare doesn’t — deductibles, coinsurance, and copays. They do not cover prescription drugs (that’s Part D’s job). Medigap is most easily purchased during your initial enrollment period; later enrollment can involve medical underwriting and higher costs.

For people with Parkinson’s who expect ongoing care, Medigap can substantially reduce the 20% coinsurance that adds up across years of therapy, imaging, and specialist visits.

Medicaid and dual eligibility

People with limited income and resources may qualify for Medicaid in addition to Medicare. Medicaid covers many services Medicare doesn’t — most importantly, long-term custodial care in nursing facilities and many home- and community-based services. Eligibility rules vary by state. Local elder-law attorneys and benefits counselors can help.

What Medicare covers for caregivers

Most caregiver-specific services (respite care, paid family caregivers) are not covered by Medicare. Some Medicaid programs do pay family caregivers; some Medicare Advantage plans have begun adding limited caregiver benefits. Check your state and plan.

Choosing or changing plans

Initial Enrollment Period: the seven-month window around your 65th birthday or 25th month of SSDI.
Annual Open Enrollment for Parts C and D: generally October 15 through December 7. New plan starts January 1.
General Enrollment Period for Part B: January through March, with coverage starting later in the year.
Medicare Advantage Open Enrollment: January 1 through March 31, for one-time changes from a Medicare Advantage plan.
Special Enrollment Periods are available for specific life events.

The Medicare Plan Finder at Medicare.gov is the most reliable tool for comparing Part D and Medicare Advantage plans. Plug in your actual medications and pharmacy to compare yearly costs accurately.

Practical tips

Compare Part D plans every year. Formularies change, and the lowest-cost plan often changes too.
Verify your team is in network if you’re considering Medicare Advantage.
Use a State Health Insurance Assistance Program (SHIP) counselor — free, unbiased help in every state.
Keep records of bills, explanations of benefits, and appeals.
Appeal denials. Many denials are reversed on appeal, particularly for therapy and durable medical equipment.
Plan for long-term care through Medicaid, long-term care insurance, family resources, or veterans’ benefits when relevant.

When to talk to a benefits counselor or attorney

You’re approaching Medicare eligibility and trying to choose between Original Medicare and Medicare Advantage.
You’ve been denied therapy, durable medical equipment, or hospitalization coverage.
You’re considering long-term care planning.
You may qualify for Medicaid in addition to Medicare.
You have employer or retiree health coverage that interacts with Medicare.

SHIP counselors are free and trained for these questions; elder-law attorneys handle more complex planning.

Frequently asked questions

Does Medicare cover physical therapy for Parkinson’s?

Yes, when medically necessary. There is no longer a hard cap, but documentation above a yearly threshold is required. LSVT BIG, PWR! Moves, and general Parkinson-specific physical therapy can usually be billed under Part B.

Will Medicare pay for a walker or wheelchair?

Yes, when prescribed and medically necessary, through Part B durable medical equipment benefits. There are coverage rules for upgrades and choice of supplier.

Does Medicare cover deep brain stimulation?

Yes, for approved indications when criteria are met. The hospital portion is Part A; programming visits are Part B.

Are Parkinson’s medications expensive under Medicare?

Cost varies. Generic carbidopa-levodopa is typically inexpensive. Some brand-name and newer medications can be costly. Comparing Part D plans against your specific medication list every year usually finds savings.

Does Medicare pay for a home health aide?

For intermittent skilled care (such as wound care or therapy), yes. For ongoing daily personal-care help (bathing, dressing), generally no. Medicaid and other programs are the usual route for that level of help.
