Medicaid and long-term care: what adult children get wrong

One of the most consequential mix-ups in caregiving is assuming Medicare will pay for a parent’s long-term nursing home stay. It generally won’t. Medicaid is the program that actually covers most long-term nursing home care in the United States — and understanding how it works, well before it’s needed, changes what families are able to do.

Medicare vs. Medicaid: the distinction that matters most

Medicare is health insurance, primarily for people 65 and older, and — as covered in Long-term care: what Medicare covers (and what it doesn’t) — its nursing home coverage is limited to short-term, skilled-care stays after a hospitalization, not ongoing custodial care.

Medicaid is a joint federal-state program providing health coverage to people with limited income and assets, and it is the primary payer for long-term nursing home care in the U.S. once someone qualifies. The Medicaid.gov overview of long-term services and supports explains what’s covered, which varies somewhat by state.

Why qualifying isn’t automatic

Medicaid is means-tested, which means a parent generally has to have limited income and countable assets to qualify. Specific limits vary by state and change periodically — a state’s Medicaid agency or an elder law attorney can confirm current figures — but the general principle is that a parent with significant savings, investments, or a second property typically needs to spend down those assets before qualifying, unless they fall under specific exemptions (a primary home up to a certain equity value, one vehicle, and personal belongings are commonly excluded, though exact rules vary by state).

The look-back period — why timing matters years in advance

States generally review a Medicaid applicant’s financial transactions going back several years (a “look-back period”) to check for assets given away or transferred for less than fair value shortly before applying. Transfers within that window can trigger a penalty period during which Medicaid won’t pay for care, even after the applicant otherwise qualifies. The Medicaid Planning Assistance overview of spend-down rules explains how this generally works and the kinds of spending that are typically treated differently than outright gifts (such as home modifications, paying off existing debt, or medical equipment).

This is the single biggest reason Medicaid long-term care planning benefits from starting years before care is actually needed, rather than being addressed during a crisis — by the time nursing home care is urgently needed, many of the planning options that would have been available years earlier are no longer on the table.

What happens if a parent is “over income” but still can’t afford care

Many states have mechanisms for people whose income exceeds the standard Medicaid limit but still can’t reasonably afford long-term care out of pocket — such as a “Miller Trust” (also called a Qualified Income Trust) that allows excess income to be redirected so it doesn’t count against eligibility. The National Council on Aging’s guidance on this scenario covers how this generally works — it’s a meaningful option many families don’t know exists.

What this means for a family planning ahead

The earlier a family understands a parent’s Medicaid eligibility picture, the more options exist — which assets to spend down and how, whether long-term care insurance makes sense, and how a spouse who isn’t entering care can be financially protected (most states have specific rules protecting a portion of a married couple’s assets and income for the spouse remaining at home). None of this is a decision to make alone or without guidance.

Where to get personalized guidance

Medicaid long-term care planning is genuinely complex and varies meaningfully by state — this is one of the clearest cases where consulting an elder law attorney isn’t optional caution, it’s the only way to actually understand a specific family’s options. The National Academy of Elder Law Attorneys directory at naela.org is a starting point for finding one.
