The question of Medicare benefits for Alzheimer’s patients is often top of mind when a loved one is diagnosed with Alzheimer’s. This article will help clarify how and when Medicare will cover medical care related to Alzheimer’s disease.
As explained by the Alzheimer’s Association, most people with Alzheimer’s progress through three stages of the disease: mild Alzheimer’s dementia (early-stage), moderate Alzheimer’s dementia (middle-stage), and severe Alzheimer’s dementia (late-stage).1
The medical and custodial care needs vary by person and from one stage of the disease to another. But these needs may include tests and procedures necessary for diagnosis, medications, care planning, mental health care, custodial long-term care, and hospice care. Other than custodial long-term care, all of these services may be covered by Medicare, as detailed below.
Medicare does spend a significant amount of money on care for beneficiaries with Alzheimer’s disease. According to the Alzheimer’s Association, Medicare pays an annual average of $21,973 for patients with Alzheimer’s or other dementia, versus $7,918 for patients without Alzheimer’s or other dementia. Unfortunately, annual out-of-pocket costs are also significantly higher for those with Alzheimer’s or other dementia: An average of $10,289 versus $2,529 for those without Alzheimer’s or other dementia.2
Roughly half of all Medicare beneficiaries are covered by Original Medicare and half have Medicare Advantage.3
For those with Original Medicare:
For those with Medicare Advantage:
Under the Medicare Part A benefit, people with Alzheimer’s are more likely to be hospitalized and more likely to receive care in a skilled nursing facility than those who don’t have the disease. (The care is often needed for conditions other than Alzheimer’s. Most people with Alzheimer’s also have at least one other medical condition.)10
Alzheimer’s is a fatal condition,11 and patients can access the Medicare Part A hospice benefit once a medical professional certifies that the patient’s life expectancy is six months or less.12
Numerous services related to Alzheimer’s disease are covered under Medicare Part B. These include:
Depending on the circumstances, Medicare Part A will pay for up to 35 hours of in-home care per week. To receive this coverage, the patient must be “homebound” and need part-time skilled nursing care.21
If full-time care is needed, the patient isn’t eligible for home health care. And home health aide care (assistance with activities of daily living) is only covered if the patient is receiving skilled care at the same time. (Skilled care can include physical, occupational, or speech therapy, or skilled nursing care.)22
If and when an Alzheimer’s patient transitions to hospice care, the hospice coverage will be provided under Medicare Part A, with very little in out-of-pocket costs. In most cases, hospice care is provided in a patient’s home.12
Some Medicare Advantage plans offer supplemental benefits for enrollees with certain chronic medical conditions. These can include assistance with some activities of daily living.23 But the specifics vary by plan and that type of supplemental benefit is much less frequently available than supplemental benefits such as dental and vision coverage.24
Yes, Medicare will generally cover FDA-approved medications for Alzheimer’s. Medicare Part D will cover self-administered medications, while Medicare Part B will cover medications administered as an infusion in a medical office.25
The Food and Drug Administration (FDA) has approved a variety of medications that slow the progression of Alzheimer’s or treat its symptoms. Different medications are used depending on the patient’s stage of Alzheimer’s.26
Some medications prescribed to Alzheimer’s patients, such as brexiprazole,27 donepezil, rivastigmine, galantamine, and memantine,28 are covered under Medicare Part D.29 (Note that each Medicare Part D plan sets its own formulary – covered drug list – so the specific drugs covered will vary from one plan to another.29)
Anti-amyloid monoclonal antibody treatments (Leqembi and Aduhelm) are administered as an infusion and are covered under Medicare Part B.30 (Note that coverage under Medicare Part B means that the beneficiary must pay 20% of the cost, after paying the Part B deductible, and there is no cap on out-of-pocket costs under Original Medicare. But Medigap plans will pay some or all of that 20% coinsurance charge.) In 2023, CMS clarified that Medicare Part B would cover infusion drugs approved by the FDA to slow the progression of Alzheimer’s under the following conditions:16
In general, a Medicare beneficiary with Alzheimer’s disease will have coverage for medications necessary to slow the progression of their disease or treat its symptoms. But since each Medicare Part D plan sets its own formulary, patients and their caregivers should evaluate their coverage each year during the Medicare annual election period. This is an opportunity to switch to a different plan if there’s an option that will provide better coverage of specific medications recommended by the patient’s doctor.
Medicare does not cover custodial long-term care in any setting, including a nursing home.31 Medicare will cover up to 100 days in a skilled nursing facility following an inpatient hospital stay, in situations where a patient needs skilled nursing care – meaning more than just assistance with activities of daily living.32
According to the Alzheimer’s Association, about a third of older adults with Alzheimer’s or other types of dementia live in nursing homes, as opposed to only about 2% of those without any form of dementia.33 And nursing home care tends to be the largest expense for people with Alzheimer’s and other dementias.34
Medicaid does cover custodial long-term care for those with limited income and financial assets. Nationwide, Medicaid is the primary payer of long-term care services.35 Millions of Medicare beneficiaries are dually eligible for both Medicare and Medicaid.36 This allows them to have coverage for their medical needs as well as their custodial long-term care needs, by utilizing the benefits of each program.
