Does Medicare Cover Dementia Treatment in 2026?
Yes — does Medicare cover dementia treatment in 2026 — across multiple care dimensions. Medicare Part B covers physician and neurologist visits for dementia evaluation and management, comprehensive cognitive assessments, diagnostic testing including brain imaging and laboratory workup, and occupational therapy for daily function. Medicare Part D covers dementia medications including cholinesterase inhibitors and memantine. Medicare Part A covers inpatient hospitalization when dementia patients develop acute medical complications. Medicare also covers home health services for homebound dementia patients at 100% when skilled care needs are present.
Dementia is a progressive neurodegenerative condition — meaning care needs increase over time as cognitive function declines. Understanding does Medicare cover dementia across the full progression of the disease helps families plan for the comprehensive and evolving care needs of loved ones with dementia.
Does Medicare Cover Dementia Cognitive Assessment?
Does Medicare cover cognitive assessment and dementia screening in 2026? Yes — and Medicare has an important free annual cognitive assessment benefit.
Annual Wellness Visit — Free Cognitive Assessment

- Cognitive impairment detection using standardized tools
- Memory and cognitive function screening
- Mood assessment — depression screening
- Review of functional ability and safety
The Annual Wellness Visit is covered at $0 for all Medicare beneficiaries — no deductible and no coinsurance. This free annual cognitive screening is one of the most important and most underutilized Medicare benefits for dementia detection.
Comprehensive Cognitive Assessment — Covered

Does Medicare Cover Leqembi and New Alzheimer Treatments?
Does Medicare cover Leqembi (lecanemab) and new anti-amyloid Alzheimer treatments in 2026? Yes — and this represents one of the most important recent expansions of Medicare Alzheimer’s disease coverage.
Lecanemab (Leqembi) — Covered Part B
Lecanemab — the first FDA-approved anti-amyloid immunotherapy shown to slow cognitive decline in early Alzheimer’s disease — is covered under Medicare Part B with specific requirements:
Coverage requirements:
- Diagnosis of early symptomatic Alzheimer’s disease — mild cognitive impairment or mild dementia stage
- Confirmation of amyloid pathology — amyloid PET or CSF biomarkers
- Appropriate clinical criteria met
Lecanemab is administered as IV infusions every two weeks — covered as a physician-administered drug under Part B at 80% after the $257 annual Part B deductible.
Lecanemab cost — Medicare-approved approximately $26,500 per year. Your 20% coinsurance without supplement — approximately $5,300 per year. With Medigap Plan G — Leqembi costs $0 after the $257 annual deductible — saving approximately $5,300 per year.
Donanemab (Kisunla) — Covered Part B
Donanemab — another anti-amyloid antibody FDA-approved for early Alzheimer’s disease — also covered under Medicare Part B with similar requirements.
Monitoring for Anti-Amyloid Therapy — Covered

Does Medicare Cover Memory Care Facilities?
Does Medicare cover memory care facilities for dementia patients in 2026? This is one of the most important and most misunderstood dementia coverage questions — and the answer requires clear explanation.
Original Medicare Does NOT Cover Custodial Memory Care
Original Medicare does not cover room and board in memory care facilities — assisted living memory care units or standalone memory care communities. This is because memory care facility residence is considered custodial care — help with activities of daily living — rather than skilled nursing care.
Medicare does not cover:
- Monthly room and board at memory care facilities
- Assisted living with memory care
- Adult day programs for dementia
When Medicare DOES Cover Nursing Facility Care for Dementia
Medicare Part A does cover skilled nursing facility (SNF) care for dementia patients when:
- The patient has been hospitalized for at least 3 days for an acute medical condition
- The SNF stay is for skilled nursing or therapy related to the hospital condition
- The patient requires skilled care — not purely custodial care
This distinction is critical — Medicare covers skilled care in SNFs after qualifying hospital stays but not ongoing custodial memory care.
Medicaid — The Primary Payer for Long-Term Dementia Care
Medicaid — not Medicare — is the primary payer for long-term memory care facility placement for patients who have spent down their assets to Medicaid eligibility. Medicare beneficiaries planning for dementia care should understand the Medicare-Medicaid interface for long-term care.
Does Medicare Cover Home Health for Dementia Patients?
Does Medicare cover home health care for homebound dementia patients in 2026? Yes — and this is one of the most valuable Medicare benefits for dementia patients.
Home Health Coverage for Dementia
Medicare covers home health services at 100% — no deductible and no coinsurance — for homebound dementia patients when:
- The patient is homebound — leaving home requires considerable effort
- A physician certifies the need for skilled care
- Skilled nursing or therapy services are needed
What Home Health Covers for Dementia Patients
Skilled nursing — medication management, wound care, health monitoring Physical therapy — mobility maintenance and fall prevention Occupational therapy — ADL training, home safety, adaptive strategies Speech therapy — swallowing and communication Social work — family support and community resource connection Home health aide — personal care when skilled services are provided simultaneously
With 100% Medicare coverage home health services for dementia patients cost $0.
Does Medicare Cover Respite Care for Dementia Caregivers?
Does Medicare cover respite care for dementia caregivers in 2026? Medicare covers limited respite care under specific circumstances.
Hospice Respite Care — Covered
When a dementia patient is enrolled in Medicare hospice Medicare covers up to 5 consecutive days of inpatient respite care — allowing the primary caregiver temporary relief. Covered at $0 under hospice benefit.
Hospice Benefit for Advanced Dementia
Advanced dementia — particularly when life expectancy is six months or less — qualifies for the Medicare hospice benefit. Medicare hospice covers:
- Palliative care and comfort measures
- Medications related to dementia symptoms
- Home health aide services
- Social work and counseling
- Chaplaincy and bereavement support
- Respite care for caregivers
The hospice benefit for advanced dementia is often underutilized — many dementia patients who would benefit from hospice comfort care are never enrolled.
Does Medicare Cover Occupational Therapy for Dementia?
Does Medicare cover occupational therapy for dementia patients in 2026? Yes — Medicare Part B covers OT for dementia at 80% after the annual deductible.
OT for dementia addresses:
- Activities of daily living maintenance — dressing bathing eating
- Home safety evaluation — fall hazard identification
- Caregiver training — safe assistance techniques

Does Medicare cover memory care facilities?
Original Medicare does NOT cover custodial memory care facility room and board. Medicare covers skilled nursing facility care after a qualifying hospital stay when skilled care is needed. Long-term memory care facility costs are primarily covered by Medicaid after asset spend-down or by private long-term care insurance.

Summary — Does Medicare Cover Dementia 2026
Does Medicare cover dementia treatment in 2026? Yes — Medicare provides comprehensive dementia coverage from free annual cognitive screening through diagnostic workup, medication management, new anti-amyloid therapies like Leqembi, home health at 100%, and hospice for advanced disease. The critical coverage gap is long-term memory care facility costs — which Medicare does not cover and which require Medicaid planning.
For dementia patients receiving Leqembi Medigap Plan G eliminates the $5,300 annual coinsurance. For all dementia patients Plan G eliminates the 20% coinsurance on neurologist visits, MRI imaging, and occupational therapy throughout the course of this chronic progressive disease.
