Care Funding

If One Parent Needs Medicaid, What Happens to the Other?

My mom was single when all of this landed on us. She and my father divorced when I was young, and by the time her diagnosis came she'd been living alone for decades. So when I finally sat down with an elder-law attorney, the answer about her money took roughly two minutes. It's hers, it pays for her care, and it pays until it's gone.

Since then I've talked with plenty of families where both parents are still living and one of them has dementia. Their version of this is harder than mine was. It's also more protective, which nobody believes the first time they hear it.

What happens to the parent still at home when the other goes on Medicaid?

Not what most families are bracing for. Medicaid treats a married couple very differently from a single applicant, and there is an entire body of federal rules built to keep the parent at home from being emptied out.

They're called the spousal impoverishment rules. The vocabulary is worth learning, because every caseworker you meet will use it and none of them will stop to define it. The parent who needs the care is the institutionalized spouse. The parent staying in the house is the community spouse. Those two people are assessed by different standards at nearly every step.

The fear families arrive with is that one parent's care will swallow both parents' lives. That was the outcome before these protections existed, which is why they were written. Your parents' situation may still be hard. It isn't supposed to be that.

Will the parent at home lose the house?

Generally not while they are living in it. The home is typically an exempt asset for as long as the community spouse lives there, and there is usually no requirement to sell it to qualify the other parent for care.

Two things get missed here. The first is that exempt doesn't mean untouchable forever. Once both parents are gone, the state can seek reimbursement from the estate, and the house is usually the largest thing left in it. That's a separate program on its own timeline, and I've written about what Medicaid can recover after death separately.

The second is that the exemption isn't automatic or unlimited. There's an equity ceiling, states apply it differently, and the protection can hinge on whether the community spouse actually lives there rather than just appearing on the deed. Ask instead of assuming.

Does the parent at home have to spend down everything too?

No. The community spouse keeps a share of the couple's countable assets, and it's a real share rather than a token one.

Here's the part that blindsides people. For assets, Medicaid counts the couple together. It does not care whose name is on the account. Your mother's own savings, opened decades before your father got sick and funded entirely out of her paycheck, gets counted right alongside his.

What she keeps is a resource allowance: a portion of the couple's combined countable assets, sitting between a floor and a ceiling set federally and adjusted every year. States have latitude in how they run that math. It's why two families in two states get different answers to what sounds like the same question.

Retirement accounts deserve their own conversation, since states treat them inconsistently. Don't assume an IRA or a 401(k) sits outside the count.

What happens to their income?

Income is counted the opposite way from assets. Assets go into one shared pot regardless of ownership. Income generally follows whose name is printed on the check.

So the parent at home keeps their own Social Security and pension. The parent receiving care generally turns most of their monthly income over toward the cost of it, keeping a small personal allowance.

Then there's the piece almost nobody walks in knowing. If the community spouse's own income falls below a minimum the state sets, part of the institutionalized spouse's income can be redirected to them instead of going to the facility. It's called a monthly maintenance needs allowance, and it exists for the parent who stayed home and never had the larger paycheck.

Ask about it by name. It isn't always offered, and it doesn't happen unless somebody asks for it.

What should we actually do first?

Stop moving money, then get the dates and the paperwork right, then hire the right lawyer. In that order.

The date matters more than families expect. Eligibility math generally runs off a snapshot of the couple's assets as of when care began, not as of when you file the application. That makes finding and documenting every account an urgent job rather than an eventual one, and it's harder than it sounds when two people have been quietly accumulating accounts for a whole marriage.

Then hire an elder-law attorney licensed where your parents live. Not a general practitioner, and not a seminar. This is a state-by-state specialty, and the gap between specific advice and generic advice gets measured in years of somebody's savings. And if your parent's capacity is already slipping with no signed authority in place, that's a separate emergency worth handling first. I've written about what to do when there's no power of attorney. Sequencing all of it, in the order that works, is most of what the full guide is.

Frequently asked questions

Will my mom have to sell the house if my dad goes on Medicaid?

Generally not while she's living in it. The home is typically exempt for as long as the community spouse lives there, and there's usually no requirement to sell it to qualify the other spouse. Two limits are worth knowing: there's an equity ceiling that states apply differently, and exempt during her lifetime doesn't mean protected afterward, since estate recovery is a separate program that runs once both parents are gone.

Does it matter whose name the money is in?

For assets, no. Medicaid counts a married couple's countable assets together regardless of which name is on the account, so a separate account belonging to the parent staying home gets counted alongside everything else. Income works the opposite way and generally follows whose name is on the check, which is why the parent at home keeps their own Social Security and pension.

Can we move the money to the kids before applying?

This is the move that backfires most often. Medicaid looks back over a period of years at gifts and below-market transfers, and a disqualifying transfer creates a penalty period when the state won't pay, no matter how sick your parent is. The community spouse protections already set aside a share for the parent at home. Talk to an elder-law attorney in their state before moving a dollar.

This isn't legal, tax, or financial advice — it's a plain-language account of how this plays out in real families, written from managing my own mom's finances since her diagnosis. Medicaid is run state by state, and the community spouse resource allowance, the income allowances, the home equity limit, and the look-back rules all vary by state and are adjusted over time. Nothing here is a figure you should act on. Confirm current requirements with your parents' state Medicaid agency, and talk to an elder-law attorney licensed where your parents live before transferring any asset or filing anything.
