No—Original Medicare does not cover 24-hour dementia care in a person's home, including continuous supervision or caregiving. Families should verify whether the proposed care qualifies as intermittent skilled home health and whether all coverage requirements are met. "24-hour dementia home care" usually means round-the-clock supervision, personal assistance, or both. Medicare's home-health coverage page expressly excludes 24-hour-a-day care at home.

Which dementia services are not covered?
Original Medicare generally does not cover long-term custodial care. Custodial care means ongoing help with daily activities such as bathing, dressing, toileting, eating, and transportation. This exclusion applies even when dementia makes that assistance essential for safety.
A need for companionship, meal preparation, or continuous supervision does not become a covered home-health benefit simply because the person has dementia. Medicare's long-term-care coverage page explains that Medicare generally does not pay for this ongoing care at home or in the community. Families may therefore face a major coverage gap when personal care—not medical treatment—is the primary need.
When can Medicare cover home health?
A dementia diagnosis alone does not establish eligibility. The person must need part-time or intermittent skilled nursing or qualifying therapy and must be homebound. Homebound does not necessarily mean unable to leave the house. It means leaving is medically discouraged or requires considerable effort and help.
A clinician must complete the required face-to-face assessment, order the care, and certify eligibility. The home-health agency providing the services must also be Medicare-certified. When those conditions are met, Medicare may cover medically necessary intermittent skilled nursing, therapy, medical social services, supplies, and limited home-health aide care. Aide services qualify only while the person also receives skilled nursing or qualifying therapy.
How many home-care hours can Medicare provide?
Even approved home health is not a substitute for around-the-clock dementia care. Combined skilled-nursing and home-health-aide services generally must remain below eight hours per day and 28 hours per week. Case-specific increases may permit up to 35 weekly hours.
However, CMS's Medicare Benefit Policy Manual makes clear that this remains intermittent care, not 24-hour coverage. For example, a person might qualify for scheduled nursing, therapy, and related aide visits while recovering or managing a medical need. Medicare would not cover the remaining hours merely because that person cannot safely stay alone.
What should families verify before care starts?
Ask the clinician and agency to identify exactly which services they expect Medicare to cover. Do not rely on a general statement that "home care" is covered.
Verify these points: The beneficiary generally owes nothing for covered home-health services. For covered durable medical equipment, the usual responsibility is 20% of the Medicare-approved amount after the Part B deductible.

Protecting appeal rights and finding other funding
Before likely noncovered services begin, request the agency's written cost explanation and Advance Beneficiary Notice. If coverage is disputed, ask the agency to submit a Medicare claim; this preserves the right to receive a coverage decision and appeal, as described in Medicare's beneficiary-protections guidance.
For ongoing supervision or personal assistance, separately investigate state Medicaid eligibility and any private long-term-care insurance. If the person has Medicare Advantage, review that plan's current materials rather than assuming its benefits match Original Medicare. Keep the clinician's certification, agency care plan, cost notices, and submitted claim together so the family can identify uncovered hours and challenge a denial if necessary.
