Medicaid does not stop at a specific age for most adults, but coverage rules change at 19, 26, and 65

Medicaid has no single cutoff age. Instead, your coverage depends on which Medicaid program you are in and what state you live in. A child on Medicaid may stay covered through age 18 or 19 depending on your state's rules. A young adult may lose coverage at 26 if they were on a parent's health plan. An adult on Medicaid for disability or income keeps it past 65, though Medicare becomes primary at that age. The age that matters most is the one that applies to your specific situation.

The confusion exists because Medicaid is not one program — it is a joint federal and state system, and each state sets its own income limits, age rules, and coverage categories. A 30-year-old in one state may have Medicaid; the same person in another state may not. Understanding which rule applies to you requires knowing which Medicaid category you are in right now.

Key Takeaways

  • Medicaid for children typically ends at age 18 or 19, depending on your state, and you may need to reapply as an adult.
  • Young adults covered under a parent's health plan may lose Medicaid at age 26, the same age limit that applies to private insurance.
  • Adults on Medicaid for disability keep coverage past 65, but Medicare becomes the primary payer once you turn 65.
  • Your state's specific rules determine when coverage ends, so contacting your state Medicaid office is the only way to know your exact cutoff date.
  • If your Medicaid ends, you may be able to switch to a different program or reapply under a different category rather than losing coverage entirely.

Medicaid for children: coverage ends at 18 or 19

If you have a child on Medicaid, coverage typically continues through the month they turn 18 or 19, depending on your state. Most states cover children through age 18. Some states, including New York, California, and Illinois, extend coverage to age 19. A few states cover through age 20 or 21 under specific circumstances, usually related to foster care or adoption.

When a child turns 18 or 19, Medicaid does not automatically switch them to adult coverage. Instead, you must reapply as an adult. The income and resource limits for adult Medicaid are often stricter than for children, so a young person who may have access to as a child may not may have access to as an adult in the same state. You will need to contact your state Medicaid office to start a new process before the child's current coverage ends.

Some states have continuous enrollment rules that prevent coverage from ending due to administrative delays, but these do not extend the age limit itself — they only protect you if paperwork is slow. Plan to reapply at least 30 days before your child's coverage ends.

Young adults on a parent's plan: coverage ends at 26

If you are a young adult covered under a parent's Medicaid plan, you may lose coverage at age 26. This age limit applies in most states and mirrors the rule for private health insurance. However, the rule is not automatic — it depends on whether your state treats you as a dependent or as an individual.

Some states allow parents to claim adult children as dependents on their Medicaid for as long as the parent remains covered. Other states require you to be removed at 26 or when you reach a certain income level, whichever comes first. A few states have no age limit for dependents and instead use income to determine coverage.

Before you turn 26, contact your state Medicaid office to learn whether you will lose coverage and what your options are. You may be able to explore as an independent adult, enroll in a parent's private insurance plan if available, or switch to a different program. Do not wait until after your 26th birthday to ask — coverage often ends on the first of the month after you turn 26, and reapplying takes time.

Adults on Medicaid for disability: coverage continues past 65

If you are on Medicaid because of a disability, your coverage does not end at 65. Medicaid for disabled adults continues as long as you remain disabled and meet your state's income and resource limits. Your disability status is reviewed periodically — usually every one to three years — but age alone does not end your coverage.

At age 65, you become may be able to access for Medicare, and Medicare becomes your primary insurance. This means Medicare pays first, and Medicaid covers costs that Medicare does not pay. You do not lose Medicaid; instead, the two programs work together. This is called "dual may be able to access" status. You will need to enroll in Medicare Part A and Part B when you turn 65, even though you already have Medicaid.

Some people on Medicaid for disability worry that turning 65 will end their coverage. It will not. What changes is the order in which the programs pay. If you are already receiving Social Security Disability Insurance (SSDI), you will be automatically enrolled in Medicare at 65. If you are on Medicaid for disability but not SSDI, you will need to enroll in Medicare yourself.

Adults on Medicaid for income: coverage ends if income rises

If you are on Medicaid as a working-age adult based on income, your coverage does not end at a specific age. Instead, it ends if your income exceeds your state's limit. In states that expanded Medicaid under the Affordable Care Act, the income limit is usually 138 percent of the federal poverty level, which is roughly $1,900 per month for a single person in 2024. In states that did not expand, the limit may be much lower — sometimes as low as $800 per month.

Your income is reviewed when you reapply, which happens once a year or when you report a change. If you earn more money and your income exceeds the limit, your coverage will end. Some states have a grace period that allows you to keep coverage for a few months after you exceed the limit, but this varies by state.

If your income rises and you lose Medicaid, you may be able to enroll in a Marketplace health plan or your employer's plan if one is available. You may also be able to reapply later if your income drops again.

What happens when your Medicaid ends

When your Medicaid coverage ends, you have a grace period — usually 30 days — to find other coverage. During this time, Medicaid will still pay for emergency services. After the grace period ends, you are uninsured unless you switch to another program.

Your options depend on why your coverage ended. If you aged out of a child or dependent category, you may be able to explore as an independent adult. If your income rose, you may be able to enroll in a Marketplace plan or your employer's insurance. If you turned 65, you must enroll in Medicare. If you lost coverage due to a change in your state's rules, you may be able to appeal or reapply under a different category.

Contact your state Medicaid office before your coverage ends to learn what options are available to you. Many people assume they will be uninsured, but other programs may cover you. Your state Medicaid office can tell you which programs you may be able to join and how the process works.

How to find your state's specific age rules

Because Medicaid rules vary by state, the only way to know when your coverage will end is to contact your state Medicaid office directly. You can find your state office through the Centers for Medicare and Medicaid Services (CMS) website, which lists contact information for every state program. You can also call 211, a free referral service, and ask for your state Medicaid office.

When you contact your state office, have your Medicaid number ready and ask specifically: "At what age does my coverage end?" and "What do I need to do before that date?" Be prepared to explain which Medicaid category you are in — whether you are a child, a dependent on a parent's plan, disabled, or covered based on income. The office staff can tell you your exact cutoff date and what happens next.

You can also check your Medicaid card or your most recent may be able to access notice, which may state your coverage end date. If the date is not clear, call the number on the back of your card and ask directly.
