Transitional Medical Assistance vs Medicaid: Eligibility and Duration

Transitional Medical Assistance and Medicaid are the same coverage delivered under different rules. Regular Medicaid is ongoing health coverage for people who meet low-income and categorical requirements, and it lasts as long as you keep qualifying. Transitional Medical Assistance, usually called TMA, is a temporary extension of that coverage — up to 12 months — for parents and caretaker relatives who lose Medicaid specifically because their earnings or work hours went up.¹ If you’re trying to figure out which one applies to you, the deciding factors are why your income changed and which Medicaid group you were enrolled under.

The Core Difference

Medicaid is a joint federal-state program covering children, pregnant women, seniors, people with disabilities, and, in many states, low-income adults.² You apply for it directly through your state, and coverage continues indefinitely as long as your income stays below the state’s threshold and you remain in a qualifying category.

TMA is narrower in every way. It exists to solve one specific problem: a parent on Medicaid takes a job or a raise, income jumps just past the eligibility cutoff, and coverage disappears at the moment the family is trying to stabilize. TMA prevents that cliff by continuing Medicaid coverage for up to 12 months.¹ You don’t apply for it. When your state Medicaid agency determines you’ve lost parent/caretaker eligibility because of earnings, TMA kicks in automatically.

Who TMA Is Actually For

Not every family that loses Medicaid qualifies for TMA. Federal law, in Section 1925 of the Social Security Act, sets three conditions, and all three have to be met:³

Your family was enrolled in Medicaid under the parent or caretaker relative eligibility group for at least three of the six months before you became ineligible.
The reason you lost Medicaid was increased earned income or increased work hours. Losing coverage for other reasons — moving to a new state, missing a renewal, a change in household composition — does not trigger TMA.
You were covered specifically as a parent or caretaker relative. Coverage under pregnancy-related Medicaid or the ACA adult expansion group doesn’t count for TMA purposes.⁴

When you do qualify, TMA covers the whole family that was on the Medicaid case, not just the working parent whose income rose.

One boundary worth flagging: in states that expanded Medicaid under the ACA, a parent whose earnings push them out of the parent/caretaker group may still qualify for regular Medicaid under the adult expansion, since that group covers adults up to 138 percent of the federal poverty level.² In non-expansion states, the parent/caretaker income cutoff can be extremely low, and TMA is often the only thing keeping a working parent covered.

How Long TMA Lasts

TMA runs a maximum of 12 months, but states structure those months in one of two ways.⁴

Two Six-Month Periods

Most states divide TMA into an initial six months and an additional six months. The first six months come with no extra strings. The second six months tighten the rules:

Your family’s average gross monthly earnings, minus necessary childcare costs for employment, cannot exceed 185 percent of the federal poverty level. For a family of four in 2026, that comes out to roughly $61,050 per year.³⁵
You have to submit quarterly reports on gross earnings and childcare expenses. Missing a report can end your coverage.
States may charge premiums during this second period.¹

Single Twelve-Month Period

Some states use a single 12-month TMA period instead. Under that option, the income cap, quarterly reporting, and premium rules for the second half do not apply. You get 12 straight months.¹ Your state Medicaid office can tell you which approach it uses.

Do Benefits Change on TMA

For at least the first six months of TMA, or the full 12 in a single-period state, your benefits are the same as regular Medicaid.³ The coverage does not shrink.

In states using the two-period structure, months seven through twelve are where things can change. States have the option to scale back certain non-acute care services during that stretch, or to offer alternative coverage such as a managed care plan or an employer-sponsored plan.⁴ Many states keep the full benefit package throughout. Ask your state agency what applies where you live.

On cost: regular Medicaid generally has no premiums for the parent/caretaker group, while TMA can carry premiums during the second six-month period in two-period states.

Your Children May Still Qualify Separately

A point that catches many parents off guard is that children’s Medicaid eligibility is separate from a parent’s and uses much higher income thresholds. Most states cover children under Medicaid at incomes up to at least 133 percent of the poverty line, and the Children’s Health Insurance Program (CHIP) extends coverage to 200 percent of FPL or higher.⁶ Even when a parent’s income rises past both regular Medicaid and TMA, children in the household often stay covered through Medicaid or CHIP. When your own coverage changes, make sure the state agency evaluates your children’s eligibility as its own question.⁷

What Happens When TMA Ends

The 12-month clock doesn’t pause or restart. Once TMA expires, you need coverage lined up, and the enrollment windows are strict.

Losing Medicaid or TMA triggers a special enrollment period on the Health Insurance Marketplace. You can apply as early as 60 days before coverage ends or up to 90 days after. Premium tax credits may substantially reduce monthly costs depending on your income.⁸
If you or a family member has access to a health plan through work, losing Medicaid or TMA opens a 60-day special enrollment window to sign up outside the employer’s regular open enrollment.⁹

Miss those windows and you’ll likely be waiting until the next Marketplace open enrollment, which runs from November through mid-January. Note the end date of your TMA coverage and start looking at options at least a month before it arrives.
