Spousal Impoverishment Rules in Montana: Protecting the At-Home Spouse

When one spouse enters a nursing home and applies for Medicaid, the other spouse should not be forced into poverty. Federal and state spousal impoverishment protections exist specifically to prevent this — but the rules are complex, and families who do not understand the math can leave tens of thousands of dollars on the table.

In Montana, the community spouse (the one who stays home) is entitled to keep a significant portion of the couple's combined assets and income. Knowing the exact thresholds and how they are calculated can mean the difference between financial stability and a devastating loss of resources.

The Community Spouse Resource Allowance (CSRA)

The CSRA determines how much of the couple's combined countable assets the community spouse can retain. For 2026, the rules work as follows:

On the date the institutionalized spouse enters the nursing home, all countable assets owned by both spouses are totaled. The community spouse can keep 50% of those combined assets, subject to:

• Maximum: $162,660
• Minimum floor: $32,532

So if a couple has $200,000 in countable assets, the community spouse keeps $100,000 (50%). If they have $400,000, the spouse keeps the $162,660 cap. If they have only $50,000, the spouse keeps the $32,532 minimum rather than the $25,000 that 50% would yield.

The remaining assets must be spent down to $2,000 for the institutionalized spouse to qualify for Medicaid. This spend-down can cover medical expenses, home repairs, prepaid burial plans, or other legitimate costs.

What Counts as a Countable Asset

Countable assets include checking and savings accounts, CDs, stocks, bonds, mutual funds, cash value life insurance (face value over $5,000), and non-exempt real property beyond the primary residence.

Exempt assets that do not enter the CSRA calculation:

• The couple's primary home (if equity is under $752,000)
• One vehicle regardless of value
• Household furnishings and personal belongings
• Prepaid irrevocable burial plans up to $5,000 per spouse
• Term life insurance policies

The snapshot date matters. DPHHS calculates the CSRA based on assets held on the date of institutional admission — not the application date. Families who restructure assets after admission lose the opportunity to maximize the community spouse's share.

Monthly Income Protections (MMMNA)

Beyond asset protections, the community spouse is also entitled to a minimum monthly income. The Minimum Monthly Maintenance Needs Allowance (MMMNA) ensures the at-home spouse receives enough to cover basic living expenses.

For July 2026 through June 2027:

• MMMNA floor: $2,705 per month
• Maximum (utility-adjusted): $4,067 per month

If the community spouse's own income (Social Security, pension, part-time work) falls below $2,705, a portion of the institutionalized spouse's income is redirected to make up the difference. This transfer happens before the patient liability calculation — meaning it reduces what the nursing home receives, not what Medicaid pays.

The utility-adjusted maximum applies when the community spouse has high housing and utility costs. The OPA eligibility specialist calculates the exact amount based on documented shelter expenses including mortgage or rent, property taxes, insurance, and utilities.

How Patient Liability Is Calculated

After the spousal income allocation, the institutionalized spouse's remaining income becomes their patient liability — the monthly amount they pay directly to the nursing facility. The calculation:

Gross monthly income

• Minus $50 personal needs allowance
• Minus private health insurance premiums (Medigap, Part B, Part D)
• Minus spousal income allocation (if applicable)
• Minus documented medical expenses not covered by insurance = Patient liability

Medicaid covers the nursing home's charges above the patient liability amount. Families should review the OPA's patient liability determination carefully — errors in this calculation are common and can cost hundreds of dollars per month.

Strategies to Maximize Spousal Protections

File for increased CSRA at a fair hearing. If the standard CSRA does not cover the community spouse's necessary assets — for example, if the home needs a new roof or the spouse relies on investment income — the community spouse can request a fair hearing to increase the resource allowance above the standard calculation.

Time the admission date strategically. Because the asset snapshot happens at institutional admission, families should ensure all legitimate assets are properly titled and documented on that date. Converting non-exempt assets into exempt ones (paying off the mortgage, buying a newer vehicle, prepaying burial plans) before admission reduces the amount that must be spent down.

Document shelter costs thoroughly. Higher documented housing expenses increase the MMMNA toward the $4,067 cap, allowing more of the institutionalized spouse's income to flow to the community spouse.

These protections are built into Montana's Medicaid framework, but they only help families who know to claim them.
