You can opt out of Medicaid whenever you want. No federal rule locks you in, and every state honors a voluntary disenrollment request from the beneficiary. The harder question is whether you should, because dropping coverage without a plan is one of the more expensive mistakes people make in health insurance, especially if you’re also on Medicare, have received long-term care, or don’t yet have another plan lined up.
How to Cancel Your Coverage
Medicaid is run state by state, so you’ll cancel through your state Medicaid agency, not the federal government. CMS maintains a directory of every state’s contact information if you’re not sure where to start.1Centers for Medicare & Medicaid Services. Contact Us Most states let you cancel by calling the consumer hotline, submitting a request through the state’s online benefits portal, or mailing a written cancellation. Some use a specific voluntary termination form.
Have your Medicaid ID and personal identification handy when you contact them. Ask for written confirmation of the request and the exact date your coverage ends. Coverage almost never stops the same day you call; most states process the termination at the end of the current month or the following month, so you may stay covered for a few more weeks. Keep every confirmation number, email, and letter. If a billing dispute later turns on whether you were covered on a specific date, that paper trail is what settles it.
Line Up Replacement Coverage First
Once Medicaid ends, you owe the full price of any care you receive. A single ER visit can run into the thousands, and routine prescriptions get expensive fast. Have new coverage in place before your Medicaid end date.
Special Enrollment Period on the Marketplace
Losing Medicaid triggers a Special Enrollment Period on the ACA Marketplace so you can buy a plan outside open enrollment. For Medicaid and CHIP loss, that window runs 90 days after your coverage ends, longer than the standard 60 days for most other qualifying events.2HealthCare.gov. Getting Health Coverage Outside Open Enrollment Ninety days passes quickly, though, and dragging your feet can leave you uninsured.
The Subsidy Trap
Here’s the catch that blindsides people. If your income is still low enough to qualify for Medicaid, you generally cannot receive premium tax credits on a Marketplace plan, even after voluntarily disenrolling. The IRS ties premium tax credit eligibility to whether you’re eligible for government coverage like Medicaid, not whether you’re actually enrolled.3Internal Revenue Service. Eligibility for the Premium Tax Credit Leave Medicaid by choice while your finances haven’t changed, and you may end up paying full price for a Marketplace plan. For most people, voluntary disenrollment only pencils out when income has actually risen above Medicaid limits or when employer-sponsored coverage is waiting.
If You Also Have Medicare
For dual-eligible beneficiaries, dropping Medicaid sets off a chain of consequences that reach well past losing a single insurance card.
Your Part B Premium Assistance Ends
Many dual-eligible individuals have their Medicare Part B premium paid by the state through a Medicare Savings Program, including the Qualified Medicare Beneficiary, Specified Low-Income Medicare Beneficiary, and Qualifying Individual programs.4Medicare.gov. Medicare Savings Programs Federal regulations on state buy-in agreements terminate that premium assistance when you lose eligibility for the buy-in group, and you become personally liable for the Part B premium starting the first month you’re no longer covered.5eCFR. 42 CFR Part 407 Subpart C – State Buy-In Agreements The standard Part B premium in 2025 is $185 per month. That’s money you weren’t paying before.
Extra Help for Prescriptions
Medicaid enrollment automatically qualifies you for the Low-Income Subsidy, known as Extra Help, which cuts Medicare Part D prescription costs substantially. Lose Medicaid, and that automatic Extra Help ends.6Centers for Medicare & Medicaid Services. Introduction to the Loss of Deemed Low Income Subsidy (Extra Help) Status Notice You can apply separately for Extra Help through Social Security and may still qualify on income and resources, but it’s a fresh application, and until it’s approved your drug costs can jump.
Estate Recovery Follows You Out
Federal law requires every state to seek repayment from the estates of people who were 55 or older when they received certain Medicaid-funded services, particularly nursing facility care, home and community-based services, and related hospital and prescription drug costs.7Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries States may also recover the cost of all other Medicaid services provided to individuals 55 and older.8Medicaid.gov. Estate Recovery
Voluntarily leaving Medicaid does not erase the tab for services already received. If you received $150,000 in nursing home care through Medicaid and then opted out, your estate still owes that amount at your death. For anyone 55 or older considering disenrollment to shield assets, the math only works forward. Opting out stops new recoverable costs from piling up. It doesn’t undo the ones already on the books.
A Word on Children
Since January 1, 2024, federal law requires states to give children under 19 in Medicaid or CHIP 12 months of continuous eligibility, so a child’s coverage normally can’t be cut mid-year over income changes.9Medicaid.gov. Continuous Eligibility CMS guidance does list a voluntary termination by the child’s representative as a valid exception.10Medicaid.gov. SHO 23-004 Continuous Eligibility A parent or guardian can still request disenrollment for a child, but replacing free comprehensive pediatric coverage with a Marketplace plan that carries premiums, deductibles, and copays is rarely a good trade unless the child is picking up coverage through a parent’s employer plan.
Coming Back Later
If your situation changes, you can reapply. There’s no cap on the number of times you can apply.11Centers for Medicare & Medicaid Services. Renew Your Medicaid or CHIP Coverage You’ll submit a new application through your state Medicaid agency or through HealthCare.gov, and the state will evaluate you on current income, household size, and any categorical criteria like disability or pregnancy.12Medicaid.gov. Eligibility Policy
Federal rules give states 45 days to process most Medicaid applications and 90 days for disability-based applications.13Medicaid.gov. Eligibility and Enrollment Processing for Medicaid, CHIP, and BHP Many applications move faster, but missing documents or complicated cases can push the timeline out. You have no Medicaid coverage during that wait.
There is one cushion. Medicaid can cover medical expenses you incurred in the three months before you applied, as long as you would have been eligible during those months. Retroactive coverage is a federal requirement, meant to protect people who delay applying during a medical crisis.13Medicaid.gov. Eligibility and Enrollment Processing for Medicaid, CHIP, and BHP Opt out and reapply within a few months, and this can retroactively pick up bills from after your disenrollment, provided you were financially eligible during that stretch.
When Opting Out Makes Sense
Leaving Medicaid is a clean call when you’ve gained employer-sponsored coverage, when your income has risen above eligibility limits, or when you’re moving to another state and will enroll there. You’re not really giving anything up, because you have better coverage or would lose eligibility soon anyway.
Opting out is riskier if you’ll be uninsured afterward, if your income is still within Medicaid range and you won’t qualify for Marketplace subsidies, or if you’re a dual-eligible beneficiary who would lose Part B premium assistance and Extra Help. Add estate recovery for anyone 55 or older, and the exposure grows. Your freedom to leave Medicaid is absolute. So is the bill for being uninsured in the American healthcare system.
