How do Medicaid waivers pay for care at home?

What a 1915(c) waiver is

Medicaid was never designed around staying home. Its long-term care spending was built on facilities, and the rules that govern it assume institutional care. In 1983 Congress added section 1915(c) to the Social Security Act, which gave states the option to receive a waiver of those institutional-care rules so that services could be delivered at home or in the community instead.

The word waiver is doing real work there. A state that operates one is not exempt from Medicaid; it is exempt from specific provisions that would otherwise shape how the benefit is delivered. Medicaid.gov describes the model as letting states tailor services to meet the needs of a particular target group, under an individualised and person-centred plan of care.

The scale of it is not marginal. Medicaid.gov reports that in 2021, 86.2% of the people using long-term services and supports received them through home and community based services rather than in an institution. Home care is no longer the exception being carved out; it is where most of the money goes.

Who the waivers are meant to cover

This is where expectations need to be set before an application is filed. A waiver programme is pointed at a defined group rather than at everyone who is eligible for Medicaid. One programme covers older adults, another covers people with intellectual or developmental disabilities, another covers a specific diagnosis. A family can be fully eligible for Medicaid and still find that the programme designed for their situation is the one with the waiting list.

Medicaid.gov also requires each waiver to demonstrate that providing services under it will not cost more than providing the same services in an institution, alongside protections for health and welfare and adequate provider standards. Cost neutrality is not a formality. It is the reason a state can run a waiver, watch the demand, and choose to cap how many people it enrols in any year rather than open the programme without limit.

The practical version: asking “does my state have a home care waiver” is the wrong first question. The useful one is which of the state's waiver programmes your situation falls under, whether that programme is currently accepting applicants, and what its functional assessment looks for.

The two federal routes: waiver and state plan

Medicaid.gov sets out two ways a state can build home and community based services into its programme. The first is the 1915(c) waiver described above. The second is the 1915(i) state plan option, which became a formal Medicaid state plan option in 2005 and lets a state write HCBS services into its state plan rather than running them through a separate, capped waiver.

The difference matters to an applicant because the two routes can have different enrolment rules. A waiver may be capped and may have a waiting list. A service delivered under the state plan route can be an entitlement for anyone who meets the state's criteria, with no separate queue. Several states use both routes at once, and which one funds the specific service a household needs is a question for the state agency rather than something a national guide can answer.

How to start an application

Everything runs through the state. Medicaid.gov is direct about the division of labour: each state Medicaid and CHIP agency has full responsibility for administering its programmes, including determining eligibility and enrolment. The federal government approves waiver programmes and the Centers for Medicare & Medicaid Services works with states on quality, but it does not process an individual application.

In sequence, an application tends to have two halves that are assessed separately. The financial half looks at income and assets against the state's Medicaid limits, which is the same set of rules that govern nursing home coverage. The countable assets guide and the look-back period guide cover that ground in detail, and the nursing home coverage rules explain why the same programme appears on both sides of the home-versus-facility question.

The functional half is the part families underrate. A clinician or assessor reviews the person's ability to manage daily activities, and it is that assessment, not the diagnosis or the family's account of how hard things have become, that decides whether the programme's threshold is met. Asking the state agency what the assessment measures, and whether it is done at home or by phone, is worth doing before anything is signed.

What a waiver does and does not pay for

A waiver typically funds a defined package rather than an open-ended care budget. The services on the list vary from state to state, and the number of hours approved is set in the person-centred plan. That means a household that needs round-the-clock help should not expect a waiver to fund it, and should plan the private portion of the bill at the same time as applying.

To size the private portion, the in-home care cost page breaks down the hourly and weekly rates, and the survey this site uses puts in-home care at 44 hours a week at $6,673 a month nationally. The care cost calculator lets a household enter its own hours and mix of settings, and the cost of care hub compares the five main settings so the waiver hours can be set against the whole plan.

One caution on timing. Waitlists move slowly, and a fall that forces the decision will not wait for one. Families usually do best when they start the financial and functional paperwork while the person is still at home and stable, rather than after a hospital discharge has turned the question urgent. The rules summarised here come from Medicaid.gov and are current as published; the specifics that decide your case come from the state agency.

Where these rules come from

Every figure and rule on this page was read from Medicaid.gov on the day it was published. The Home & Community Based Services page supplied the 86.2% share of long-term services and supports users receiving HCBS in 2021. The Home & Community Based Services Authorities page supplied the 1983 addition of section 1915(c) to the Social Security Act, the 2005 state plan option, and the statement that forty-seven states and DC operate at least one 1915(c) waiver. The 1915(c) page supplied the statement that nearly all states and DC offer services through HCBS waivers, the figure of about 257 active HCBS waiver programmes, the requirement that a waiver cost no more than institutional care, the health and welfare and provider standards, the person-centred plan of care, and the targeting of programmes to a particular group. The Medicaid.gov beneficiary resources wording supplied the statement that state agencies decide eligibility and enrolment. Care costs are the 2025 national medians published by the cost survey named above. This is not legal or benefits advice for an individual case.
