What Is Medicaid Spousal Impoverishment Protection?

When one spouse applies for long-term-care Medicaid and the other stays at home, federal law protects the at-home spouse from being left without enough to live on — through a resource allowance (the CSRA) and, when the at-home spouse's own income is low, a monthly income allowance (the MMMNA) that can draw on the applying spouse's income, including income that's flowing through a Miller Trust in states that require one. The exact dollar figures are set annually and vary by state; this page explains the mechanism, not a specific number.

Why this exists

Before 1988, a couple could be required to spend down nearly everything — including the at-home spouse's own resources and income — before the spouse needing care could qualify for Medicaid. The Medicare Catastrophic Coverage Act of 1988 (42 U.S.C. § 1396r-5) changed that with two protections for the community spouse — the spouse who isn't applying for long-term-care Medicaid — so that one spouse needing care doesn't financially wipe out the other.

The Community Spouse Resource Allowance (CSRA)

The CSRA lets the community spouse keep a share of the couple's combined countable resources, on top of the applying spouse's own resource limit, without it counting against the applicant's eligibility. Federal law sets a minimum and maximum CSRA that update every year; each state picks where within that range it falls, and some calculate a couple-specific "spousal share" based on what the couple owned at the start of care rather than a flat figure. This is one of the first numbers an elder-law attorney or the state Medicaid agency will confirm when a married couple starts the application process.

The Minimum Monthly Maintenance Needs Allowance (MMMNA)

The MMMNA works on the income side. If the community spouse's own monthly income falls below the MMMNA floor, some of the applying spouse's income can be diverted to bring the community spouse up to that floor — before whatever remains goes toward the cost of the applying spouse's care. Like the CSRA, the federal government sets a range and each state sets its own current figure and formula within it.

How this connects to a Miller Trust

In states where the applying spouse's income has to be diverted into a Miller Trust (Qualified Income Trust) to qualify, the MMMNA protection doesn't disappear — many states' trust rules still make room for a spousal allowance in the monthly distribution order, before the rest goes to the cost of care. Exactly how that works — and the current dollar figures for both the CSRA and the MMMNA — is set by each state, not a single national rule, which is why this page explains the mechanism rather than a number. Each state guide on this site cites the current figures and the specific distribution order that state's own Medicaid agency requires.

What if both spouses need care?

Everything above assumes one spouse is applying for long-term-care Medicaid while the other stays home. If both spouses need care, the calculation changes — each may need their own eligibility path, potentially including their own Miller Trust if the state requires one, and the spousal allowances above generally don't apply the same way. That fact pattern is worth raising directly with an elder-law attorney rather than assuming either way.

Frequently asked questions

What is Medicaid spousal impoverishment protection?

It's a set of federal protections — from the Medicare Catastrophic Coverage Act of 1988 (42 U.S.C. § 1396r-5) — for the spouse who stays at home (the "community spouse") when their husband or wife applies for long-term-care Medicaid. Without it, a couple's combined income and resources could be counted against the applying spouse's eligibility to the point that the at-home spouse is left without enough to live on. The law fixes this with a resource allowance and, when needed, a monthly income allowance.

What is the Community Spouse Resource Allowance (CSRA)?

The CSRA is the amount of a couple's combined countable resources the community spouse gets to keep, on top of the applying spouse's own $2,000 individual limit, without it counting against the applicant's eligibility. Federal law sets a minimum and maximum CSRA that update annually; each state picks where within that range it falls, and some use a "spousal share" calculation based on the couple's actual resources at the start of care. The current figure for a specific state is one of the things an elder-law attorney or that state's Medicaid agency confirms as part of the application.

What is the Minimum Monthly Maintenance Needs Allowance (MMMNA)?

The MMMNA is a floor on the community spouse's own monthly income. If the at-home spouse's own income falls below that floor, some of the applying spouse's income can be diverted to the community spouse to close the gap, before whatever remains goes toward the cost of care. Like the CSRA, the federal government sets a range and each state's exact current figure — and the formula used to calculate it — varies.

Can a Miller Trust help fund the community spouse's allowance?

In many income-cap states, yes, at least in part — when the applying spouse's income has to be diverted into a Miller Trust (Qualified Income Trust) to qualify, the trust's monthly distribution order can still make room for the community spouse's allowance before the remainder goes to the cost of care. Whether and how that works is set by each state's own trust rules, not a national formula, so it's not something this page states as a blanket fact — it's exactly the kind of detail a state-specific Miller Trust guide is built to get right.

Does spousal impoverishment protection apply if both spouses need care?

The protections described here specifically assume one spouse is applying for long-term-care Medicaid while the other remains at home. If both spouses need long-term care, the situation is different — each may need their own eligibility path (potentially their own Miller Trust, if their state uses one), and the spousal allowances above generally don't apply the same way. That's a fact pattern worth raising directly with an elder-law attorney rather than assuming either way.
