A Medicaid spend down is an eligibility pathway that lets you qualify for Medicaid when your income sits above your state’s limit, by subtracting the medical bills you’ve incurred from the amount you’re over. It works like a health insurance deductible: once your medical expenses in a given period equal the gap between your income and the state’s threshold, Medicaid turns on and covers the rest of that period. Thirty-six states and the District of Columbia offer some form of this program, and the rules vary meaningfully from one state to the next.
How the Calculation Works
Every state with a spend down sets a Medically Needy Income Limit (MNIL). That’s the income ceiling you have to get under. Subtract the MNIL from your countable monthly income and the difference is your monthly spend down amount.1Medicaid.gov. Implementation Guide: Medicaid State Plan Eligibility Handling of Excess Income (Spenddown)
States run the program on defined budget periods of one, three, or six months. Whatever your monthly excess is, you multiply it by the number of months in the period to get the total you need to cover with medical bills.2eCFR. 42 CFR 435.831 – Income Eligibility
An example. Say your countable income is $1,500 a month and your state’s MNIL for a single person is $1,200. Your excess is $300. In a state with a three-month budget period, you need to show $900 in medical expenses ($300 × 3) before Medicaid activates for the remainder of the period.
MNILs are not uniform. Each state sets its own, adjusts it for household size, and in some cases varies it by region. Across states, the figure for a single individual runs from roughly $475 to nearly $1,800 per month.
What Counts as Income
Countable income isn’t necessarily your gross income. Federal rules allow certain deductions before the spend down math starts. Social Security, pensions, and wages are generally counted, but some income is excluded or reduced, and earned income often gets a partial disregard. The specifics depend on whether your state uses SSI counting rules or its own methodology.3Social Security Administration. POMS SI 01715.010 – Medicaid and the Supplemental Security Income Program
Which Bills Count Toward the Spend Down
Federal rules require states to accept a broad range of medical costs. Health insurance premiums (including Medicare premiums) and out-of-pocket prescription costs are the two categories that eat up the largest share of most people’s spend down each period.2eCFR. 42 CFR 435.831 – Income Eligibility
Beyond premiums and medications, qualifying expenses include:
- Doctor and hospital charges: copays, deductibles, and bills from any licensed provider
- Dental and vision care, including exams, eyeglasses, and dentures
- Medical equipment and supplies such as wheelchairs, hearing aids, and bandages
- Nursing home costs, home health aides, and adult day services
- Transportation to medical appointments, in some states
States must also count expenses for health services recognized under state law even when those services are not covered by Medicaid itself.2eCFR. 42 CFR 435.831 – Income Eligibility
Old and Unpaid Bills Still Work
You do not have to have paid a medical bill for it to count. You only need to have incurred it, meaning you are legally on the hook for it. An outstanding hospital bill from months ago is just as usable as a receipt from last week.1Medicaid.gov. Implementation Guide: Medicaid State Plan Eligibility Handling of Excess Income (Spenddown)
How far back you can reach depends on the state. Eight states operating under the 209(b) option place no age limit on a medical bill, as long as you still owe it and haven’t already applied it to a prior spend down period. Other states may set an age limit, but they must accept bills incurred in at least the three months before your application.1Medicaid.gov. Implementation Guide: Medicaid State Plan Eligibility Handling of Excess Income (Spenddown)
This is one of the most valuable pieces of the process. If you’ve been carrying medical debt you couldn’t afford to pay, those unpaid balances may be what pushes you into eligibility. Confirm with your state agency that the provider hasn’t written the bill off or forgiven it, because once you’re no longer liable, the expense can’t be counted.
When Coverage Starts, and How Long It Lasts
Once the agency verifies your submitted expenses meet or exceed your spend down amount, coverage activates from the date you met the spend down through the end of the current budget period. Medicaid does not pay back the bills you used to get there. Those stay yours. Treat them as the deductible you cleared to unlock coverage.
There is one meaningful exception. If a single bill pushes you across the spend down line, Medicaid may cover the portion of that bill above the threshold. A $1,000 hospital bill in a period where your spend down is $600 could leave Medicaid picking up the remaining $400.
Coverage isn’t permanent. When the budget period ends, a new one begins and you have to meet the spend down again. The cycle continues as long as your income stays above the MNIL, so people who rely on this pathway learn to track expenses tightly and submit them fast. Any delay means a stretch of the next period where you’re paying full freight.
Retroactive Months
Federal rules let states include up to three months before your application in the first budget period, as long as you received covered services during those months. Expenses from that window can count toward your spend down, and coverage can reach back to pay for services provided during it. Not every state applies this the same way, so ask specifically about retroactive coverage when you apply.2eCFR. 42 CFR 435.831 – Income Eligibility
Submitting the Paperwork
Documentation needs to show who received the care, what the service was, when it was provided, who provided it, and the amount owed. Itemized hospital statements, pharmacy receipts, and insurance premium notices all work. Send copies and keep your originals. Most states accept documents by mail or in person; some now offer online portals. Call your state’s Medicaid office to confirm the intake method they want, because a misfiled document can delay coverage by weeks.
What If Your State Doesn’t Offer One
Not every state has a spend down. Roughly half do not. These “income-cap” states set a hard ceiling, and if your income exceeds it, the spend down pathway doesn’t exist for you. In 2026, that cap is typically 300% of the SSI federal benefit rate, or $2,982 per month.4Social Security Administration. SSI Federal Payment Amounts for 2026
The workaround is a Qualified Income Trust, commonly called a Miller Trust. You set up an irrevocable trust, deposit enough of your monthly income into it that what remains falls below the cap, and Medicaid stops counting the deposited amount for eligibility purposes. The trust must name the state as remainder beneficiary, meaning any funds left when you die go to reimburse Medicaid.
Miller Trusts require careful setup. The document has to meet specific legal requirements, deposits must happen every month, and the trust can only hold income, not assets. Most people use an elder law attorney, with setup costs generally running from a few hundred to a couple thousand dollars.
The Asset Test Is Separate
Income is only half the financial picture. Medicaid also looks at countable assets, and in most states the limit for an individual who is aged, blind, or disabled is $2,000. If your assets exceed that, you’ll need to reduce them before you qualify, which is a different process from the income spend down described above.
Many assets don’t count. The biggest exclusions are your primary home (as long as you, your spouse, or a dependent relative lives there or you intend to return), one vehicle, household goods and personal belongings, designated burial funds (often up to $1,500 under SSI-related rules, though some states allow more), and life insurance policies with a combined face value of $1,500 or less. Bank accounts, stocks, bonds, second properties, and additional vehicles generally count. Married couples where both spouses apply usually face a combined limit of $3,000, though this varies by state.
Two things not to do. First, don’t confuse spending down assets with the income spend down. Spending down assets means using them for legitimate expenses of your own before you apply. Second, don’t give assets away. Medicaid reviews transfers made during the 60 months before your application, and gifts or below-market sales during that window can trigger a penalty period during which the program won’t pay for long-term care.5Office of the Law Revision Counsel. 42 U.S. Code 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets
If you’re married and one spouse needs long-term care while the other stays at home, separate spousal impoverishment rules protect part of the couple’s income and assets for the at-home spouse. Those rules sit alongside the spend down process and use their own 2026 figures.6Centers for Medicare & Medicaid Services. 2026 SSI and Spousal Impoverishment Standards
Running the Cycle Well
The spend down rewards organization. Keep a running log of every medical expense as you incur it: date, provider, amount, and whether it’s paid. When the total hits your spend down amount, submit right away. The sooner you clear it, the more of the budget period Medicaid covers.
Front-load expenses when you can. Schedule appointments, refill prescriptions, and handle elective procedures early in the period. People who wait until the last few weeks to accumulate bills often end up with only a sliver of coverage, or miss the window.
If you meet your spend down every period, ask your caseworker whether the state allows recurring expenses like Medicare premiums to be automatically applied at the start of each cycle. Some do, which cuts paperwork and shortens the gap before coverage begins.
Keep copies of everything. Agencies lose paperwork, and if your bills go missing mid-review, you’ll be resubmitting. A folder organized by budget period, physical or digital, saves real trouble when a decision gets delayed.
