Medicare Coverage for Dementia: A Detailed Look
The Critical Difference: Skilled vs. Custodial Care
To understand how Medicare covers dementia, you must first grasp the distinction between skilled and custodial care. Medicare is primarily designed to cover medical treatments, not long-term daily assistance. While a person with dementia may need both, Medicare's coverage is strictly for the medical component.
- Skilled Care: Medically necessary services that require the skills of a registered nurse or a licensed professional therapist. This includes rehabilitation after a hospital stay or managing a specific illness. This is what Medicare will cover, but for a limited time.
- Custodial Care: Non-medical care for daily living activities, such as bathing, dressing, and eating. This is the bulk of long-term dementia care and is generally not covered by Medicare. This includes prolonged stays in nursing homes or assisted living facilities where the primary need is for personal assistance rather than medical treatment.
Medicare Part A: Hospital and Skilled Nursing Facility Coverage
Part A, or Hospital Insurance, is where Medicare's most significant, yet still limited, benefit for facility-based dementia care lies. Coverage is not for indefinite periods.
Skilled Nursing Facility (SNF) Stay: The 100-Day Limit
Medicare Part A may cover up to 100 days of skilled nursing care per benefit period, but only after a qualifying hospital stay of at least three days. This is not a guaranteed 100 days and is subject to strict conditions.
- Qualifying Hospital Stay: You must have been admitted to a hospital as an inpatient for at least three consecutive days before being transferred to the SNF.
- Medical Necessity: The SNF care must be for a condition that was treated during the hospital stay. Your doctor must certify that you need daily skilled care, such as physical therapy or IV medication management, not just custodial care.
- Cost-Sharing: For the first 20 days, Medicare pays the full cost. From day 21 to day 100, you are responsible for a daily copayment. After day 100, all costs are your responsibility for that benefit period.
Hospice Care for End-of-Life
When a doctor certifies that a person with dementia has a life expectancy of six months or less, Medicare Part A will cover hospice care. This can be provided at home, in a hospice facility, or a nursing home. Hospice coverage is comprehensive and includes services like doctor and nursing care, personal care, and counseling.
Medicare Part B: Outpatient and Diagnostic Services
Part B, or Medical Insurance, covers a range of outpatient services and is essential for diagnosing and managing dementia, but it does not pay for long-term care.
- Cognitive Assessments: Part B covers a separate visit with a doctor to perform a cognitive assessment, confirm a diagnosis, and develop a care plan.
- Outpatient Therapy: Services like physical, occupational, and speech therapy are covered if a doctor deems them medically necessary.
- Medical Equipment: Durable medical equipment (DME), such as wheelchairs, walkers, and hospital beds, is covered, typically with a 20% coinsurance after the Part B deductible is met.
- Diagnostic Tests: Part B covers diagnostic testing, including certain PET scans, which are crucial for confirming a dementia diagnosis.
Medicare Part D: Prescription Drug Coverage
Prescription drug costs are not included in Original Medicare (Parts A and B). Individuals with dementia must enroll in a separate Part D plan or a Medicare Advantage plan that includes drug coverage to help pay for medications used to manage dementia symptoms.
Coverage Comparison: Medicare vs. Medicaid
This table outlines the distinct differences in what Medicare and Medicaid cover regarding dementia care, highlighting why families need to consider other options for long-term needs.
| Feature | Medicare | Medicaid |
|---|---|---|
| Skilled Nursing Facility | Up to 100 days per benefit period (after a qualifying hospital stay) | Generally covers long-term nursing home stays for eligible individuals |
| Custodial Care | Generally not covered | Covers care in nursing facilities and sometimes at home for low-income individuals |
| Assisted Living/Memory Care | Not covered; may cover specific medical services within the facility | May cover some services, but typically not room and board |
| Home Health Aide | Covered for limited, intermittent periods if a person is certified as homebound and needs skilled care | Can provide extensive in-home personal care services for eligible individuals |
The Role of Supplemental Insurance and Other Programs
Since Medicare coverage is so limited, many families need to look elsewhere to cover the high cost of long-term dementia care. Medigap plans can help cover some of the costs that Original Medicare doesn't, such as the copay for skilled nursing facility stays. Medicaid, a state-federal program, is a primary payer for long-term care for low-income individuals.
Another option is the Program of All-Inclusive Care for the Elderly (PACE), available in some areas. PACE provides a comprehensive range of medical and social services to help people with dementia stay in their homes.

The Importance of Early Planning
Due to the progressive nature of dementia and the limitations of Medicare, early financial and legal planning is essential. Families should proactively research all options, including long-term care insurance and Medicaid eligibility, before a crisis occurs. Understanding these coverage boundaries is the first step toward securing sustainable, long-term care for a loved one with dementia.
Conclusion
Medicare's role in dementia care is crucial for medical needs, diagnostics, and short-term skilled care, but it is not a long-term care solution. The 100-day limit on skilled nursing facility stays and the exclusion of most custodial care means that families must consider alternative funding and care options. By understanding Medicare's limitations and exploring other resources like Medicaid and private insurance, caregivers can better prepare for the financial realities of dementia care.
