Medicaid Continuous Eligibility for Children: 12-Month Rule

Since January 1, 2024, every state must give children under 19 a full 12 months of continuous Medicaid or CHIP coverage, even if the family's income goes up partway through the year. This protection, called continuous eligibility, keeps a child who has been found eligible enrolled for the entire 12-month period, so a raise, a new job, or a seasonal bump in earnings won't cut coverage off mid-year. It's a federal requirement now, not a state option, and it works the same way in every state.1

What Medicaid Continuous Eligibility for Children Actually Means

Continuous eligibility is a rule about timing. When a state finds a child under 19 eligible for Medicaid or CHIP, that child keeps the coverage for a fixed 12-month stretch that starts on the date of the eligibility decision. During those 12 months, the coverage does not turn off because the household's circumstances changed. A parent picking up more hours, a second earner returning to work, or a one-time increase in income does not, by itself, end the child's coverage before the period is over.

This became a nationwide requirement through Section 5112 of the Consolidated Appropriations Act, 2023, which amended the Social Security Act at 42 U.S.C. 1396a(e)(12) and the parallel CHIP provision. The statute says a state plan "shall provide that an individual who is under the age of 19" and found eligible "shall remain eligible" until one of a short list of end points is reached. It is implemented for Medicaid at 42 CFR 435.926 and took effect January 1, 2024.1

The word that matters is "mandatory." For years, states could offer 12-month continuous eligibility to children, and many did, but it was optional and the length varied. The Consolidated Appropriations Act converted that option into a federal floor: every state now has to provide the full 12 months for children under 19 in both Medicaid and CHIP.1

What Can End Coverage Before the 12 Months Are Up

The statute is specific about what closes the 12-month window. A child stays enrolled until the earliest of three things happens:

• The 12-month period ends. This is the normal case: coverage runs its full year and the child comes up for the annual renewal.
• The child turns 19. Continuous eligibility for children applies to individuals under age 19, so reaching 19 ends the protected period.
• The child stops being a resident of the state. Coverage is tied to residency, so a move out of the state ends eligibility in that state.

That list is what the law names, and a rising income is not on it. Under 42 U.S.C. 1396a(e)(12), a child who was found eligible "shall remain eligible" until the earlier of the end of the 12-month period, turning 19, or ceasing to be a state resident. An income increase during the year does not appear among those end points, which is the entire point of continuous eligibility: it holds the child's coverage steady across ordinary mid-year changes.1

Why You Should Still Report Income and Address Changes

Continuous eligibility protects your child's coverage during the 12 months. It does not mean you should stop telling your state agency about changes, and two of the three end points above are the reason.

Residency is one of them. Under 42 U.S.C. 1396a(e)(12), a child ceasing to be a resident of the state is one of the events that ends the protected period, so if your family moves to another state, the child's eligibility ends in the old state and you'll need to apply in the new one.1 A current address on file is also what keeps renewal notices reaching you instead of going to an old mailbox. Reporting a move promptly is how you avoid a gap when the family relocates.

Income is the other reason, but on a delay. A higher income won't end coverage mid-year, yet it is exactly what the state re-checks at the annual renewal. Knowing where your household income stands before renewal time lets you see it coming if the child is heading toward a different coverage category, rather than being surprised by the redetermination notice. If you're unsure whether a change matters, your state Medicaid agency can tell you what it needs and when.

How Continuous Eligibility Works With Your Children's Medicaid Renewal

The 12-month clock and the annual renewal are two halves of the same cycle. Continuous eligibility carries the child through the 12 months; the renewal is what happens at the end of them.

When the period closes, the state redetermines eligibility based on the household's current situation. One of three things follows. If the family still qualifies at the same level, coverage continues and a fresh 12-month period begins on the date of that new determination. If income has risen past the Medicaid line but is still within the range for CHIP, the child may move from Medicaid to CHIP, where the same 12-month continuous eligibility requirement for children under 19 applies.1 If income is now above both limits, the child may no longer qualify, and the renewal is where that determination is made, not somewhere in the middle of the year.

Because the renewal is the decision point, it's worth responding to every renewal request on time and confirming your income and household details are current. For the step-by-step process and where each state takes applications and renewals, see our guide on how to apply for Medicaid by state. The income thresholds that decide which category a child lands in are laid out in Medicaid income limits by state.

Does This Apply in Every State?

Yes. This is a federal mandate, not a state-by-state option, so the 12 months of continuous eligibility for children under 19 apply in all 50 states and the District of Columbia, in both Medicaid and CHIP, as of January 1, 2024. CMS confirmed the requirement in a letter to state health officials, stating that states must provide 12 months of continuous coverage for children under age 19.1

What still varies by state is the surrounding machinery: which agency runs the program, where you apply, and the income limits that decide whether a child qualifies for Medicaid or for CHIP in the first place. The 12-month protection itself is uniform. To find your state's agency, income figures, and process, start with Medicaid by state.
