Nursing home care stays mandatory because federal Medicaid law lists nursing facility services for adults age 21 and older as a required benefit. Home care for dementia may not because home and community-based services, or HCBS, are optional waiver programs that states can limit and cap. HCBS covers help at home or in the community, such as personal care, homemaker help, and supervision. For dementia families, that legal split decides whether coverage is guaranteed or depends on a state slot.

Why does Medicaid treat the two settings differently?
Federal law divides Medicaid benefits into mandatory and optional groups. According to MACPAC, nursing facility services for adults are mandatory, so every state program must cover medically necessary nursing-home care under federal Medicaid benefit rules. HCBS under Section 1915(c) waivers sits on the optional side.
States may target specific groups, define covered services, and set enrollment caps. That choice is not about medical value. It reflects how Congress wrote the benefit categories.
What changes when home care has a cap?
Nursing-home Medicaid works as an entitlement with no enrollment cap or waitlist. HCBS waiver programs may keep waiting lists once funded slots fill, according to KFF survey data on Medicaid home-care waiting lists from 2016 to 2025. In 2024, about 710,000 people were on HCBS waiver waitlists in 40 states.
The average wait was around 40 months. For dementia, a long wait matters because needs are daily and progressive. A family may qualify on paper but still wait years for an open home-care slot.
Does Medicare pay for ongoing dementia home care?
Original Medicare does not cover custodial-only care, meaning help with bathing, dressing, eating, and similar daily activities at home or in a nursing home, according to Medicare.gov guidance on what Original Medicare excludes in nursing homes. Medicare home-health coverage is narrower.
It is limited to part-time skilled nursing or therapy for homebound patients and expressly excludes 24-hour home care, meals, homemaker services, and personal care alone. Dementia often requires years of supervision and daily-activity help rather than short-term skilled care. Families therefore generally need state Medicaid HCBS, veterans benefits, or private pay for ongoing home support.
What can families do now?
Start with the state Medicaid agency, not assumptions from another state. Ask whether dementia is covered under an HCBS waiver, what services are included, whether enrollment is capped, and how the waitlist works.
Also plan for coverage gaps. Short-term Medicare home health, veterans programs, local aging agencies, adult day programs, and paid caregivers may bridge part of the need. Recheck eligibility after a hospital stay, fall, move, or change in supervision needs.
- Get the waiver name, eligibility rules, and application path in writing
- Ask about income, asset, medical-need, and home-safety reviews
- Ask current wait times and interim services while waiting
- Keep copies of diagnoses, functional assessments, and submitted forms
