Alzheimer’s and Medicare
An Alzheimer’s diagnosis can feel overwhelming, especially when you’re trying to understand what Medicare will actually cover. The good news is that Medicare does help with many parts of care—but not everything.
This guide explains what Alzheimer’s is, what to watch for, and how Medicare may help with diagnosis, treatment, and support.
What Is Alzheimer’s?
Alzheimer’s is a progressive brain disease that affects memory, thinking, and behavior over time. It’s the most common cause of dementia.
What this means for you
Symptoms often start slowly and worsen over time
Daily tasks may become harder

Common Questions
Common Symptoms and Warning Signs
Early symptoms can be subtle and easy to overlook.
Memory loss that disrupts daily life
Trouble planning or solving problems
Difficulty completing familiar tasks
Confusion with time or place
Changes in mood or personality
What to watch for
Ongoing or worsening symptoms—not occasional forgetfulness—should be evaluated by a doctor.
Why Alzheimer’s Matters
Alzheimer’s affects not just the person diagnosed, but also family and caregivers.
Millions of Americans are living with Alzheimer’s
Care often extends for years
Costs can be significant—especially long-term care
What this means for you
Understanding coverage early helps reduce stress and avoid financial surprises later.
Causes and Risk Factors
The exact cause isn’t fully understood, but several factors increase risk:
Age (strongest risk factor)
Family history
Genetics
Lifestyle and cardiovascular health
People often don’t realize
Some medical conditions—like vitamin deficiencies or thyroid issues—can mimic Alzheimer’s symptoms and may be reversible.
Prevention and Screening
Annual Wellness Visit (AWV)
Medicare covers a free yearly wellness visit that includes a basic cognitive screen.
Cognitive Assessment & Care Plan
If concerns arise, Medicare Part B may cover a more detailed evaluation (CPT 99483).
Why this matters
Early detection allows for:
Better planning
Safer living arrangements
Access to treatments and support
If you’re at higher risk, ask your clinician what yourtop three prevention priorities are. A short list is easier to follow.

How Alzheimer’s Is Diagnosed
Diagnosis involves several steps, often covered by Medicare when medically necessary:
Cognitive testing
Specialist evaluations
Bloodwork
Brain imaging (MRI, CT, PET)
Amyloid PET scans (in certain situations)
What this means for you
There is no single test—diagnosis is a process guided by your doctor.
How Medicare May Cover Diagnosis
Most diagnostic services fall under Medicare Part B:
Doctor visits and specialists
Lab tests and imaging
Cognitive assessment services
You typically pay:
A deductible
About 20% coinsurance
Treatment Options
Alzheimer’s treatment focuses on:
Managing symptoms
Maintaining independence
Supporting quality of life
Common approaches
Therapy (physical, occupational, speech)
Mental health support
Care planning
Home safety adjustments
Alzheimer’s treatment focuses on managing symptoms, maintaining function, and supporting quality of life.

How Medicare May Cover Treatment
Part A (Hospital)
Skilled Nursing Facility (after 3-day inpatient stay)
Hospice care
Part B (Medical Services)
Therapy services
Mental health care
Durable medical equipment
Home health (if skilled care is required)
What this means for you
Coverage is tied to medical necessity—your doctor must approve services.
Recovery and Support
Recovery looks different for Alzheimer’s. Support is ongoing rather than short-term.
Medicare may cover:
Home health services (limited, skilled care only)
Therapy to maintain function
Care coordination programs like GUIDE
Important note
Custodial care (help with bathing, dressing, eating) is not covered unless paired with skilled care.
Medications
Symptom Management (Part D)
Medicare Part D may cover medications such as:
Cholinesterase inhibitors
Memantine
Certain mental health medications
How Medicare May Cover Medications
Covered through Part D plans
Costs vary by plan (deductibles, copays, coinsurance)
Disease-Modifying Treatments (Part B)
Newer treatments target amyloid plaques in the brain.
Examples:
Leqembi (lecanemab)
Kisunla (donanemab)
Coverage requirements
Early-stage Alzheimer’s
Confirmed amyloid plaques
Participation in a Medicare registry
Administered via infusion
What this means for you
These treatments may slow progression—but do not cure Alzheimer’s.
After meeting these criteria, Medicare Part B covers the infusion and monitoring services — you pay 20% coinsurance after your deductible.
What Medicare May Not Fully Cover / Costs to Watch
Medicare does not typically cover:
Long-term custodial care
Memory care facility housing
Assisted living room and board
24-hour home care without skilled services
What to watch for
These costs are often the largest—and require separate planning.
Medicare Advantage Considerations
Medicare Advantage plans must cover everything Original Medicare covers—but may have:
Network restrictions
Prior authorization requirements
Different cost structures
What this means for you
Check your plan details carefully—coverage and costs can vary.
