The short answer
A permanent move to a new state usually gives you a special enrollment period of 60 days to sign up for new coverage, outside open enrollment. Most health plans don't fully follow you across state lines, so plan the switch before you go:
- Marketplace plan: report the move, enroll in the new state (up to 60 days before or after), and line up the start and end dates.
- Employer plan: tell HR before you move; check the network in your new ZIP code.
- Medicaid: it doesn't transfer. Apply in the new state as soon as you arrive.
- Between jobs: compare COBRA with a Marketplace plan. COBRA keeps your old plan but is expensive and may not have a network where you're going.
Health insurance is the moving job people forget until they need a prescription refilled in a new city. It's also the one where a mistake (cancelling too early, missing the 60-day deadline) can leave you uninsured for months. If you're moving to close the distance, there's often a second complication: one of you is changing jobs, or you're about to get married, or a partner is arriving from abroad. This guide covers all of that. It's US-focused; rules and dates are as of 2026, so confirm details on HealthCare.gov or your state's exchange.
Why moving affects your health insurance
- Plans are sold by state and area. Marketplace plans are approved state by state, often for specific counties.
- Networks are local. Even big national insurers run different networks in different states. Your new doctors may be out of network.
- Medicaid is run by each state, with different eligibility rules.
- Prices change with your ZIP code. The same coverage can cost very different amounts in different places.
Emergencies are a partial exception: plans are generally required to cover emergency care at out-of-network emergency rooms, and the federal No Surprises Act limits surprise bills in many emergency situations. Routine and ongoing care is where moving bites.
How the special enrollment period for moving works
Outside the annual open enrollment window, you can only buy or change Marketplace coverage after a "qualifying life event." A permanent move to a new state (or a new ZIP code or county with different plans) is one of them.
| Rule | What it means in practice |
|---|---|
| 60-day window | You can usually enroll from 60 days before the move to 60 days after it. |
| Prior coverage | You generally need to have had qualifying health coverage for at least one day in the 60 days before the move. Exceptions include moving from another country or a US territory. |
| Proof | You may be asked for proof of the move (lease, utility bill, mortgage) and of prior coverage. |
| Start date | If you enroll before the move, coverage can start the first of the month after you move. If you enroll after, it usually starts the first of the month after you pick a plan. |
| Miss it | You'll generally have to wait for open enrollment, unless another qualifying event (like marriage or losing job-based coverage) comes along. |
If you have a Marketplace (ACA) plan
- Shop early. Up to 60 days before the move, preview plans for your new ZIP code on HealthCare.gov or your new state's exchange. About 20 states run their own exchange (California, New York and Massachusetts among them), so the right website depends on the state.
- Report the move and apply in the new state. Select a plan, aiming for it to start the month you arrive.
- End the old plan effective the day before the new one starts. Don't cancel first.
- Update your income estimate. If you or your partner changed jobs, your premium tax credit will change. Getting it wrong means repaying or missing money at tax time.
- Check the new plan's network for the doctors and pharmacy you'll actually use, and the formulary for your prescriptions.
Financial help (premium tax credits, and cost-sharing reductions on Silver plans for lower incomes) depends on income, household size and where you live. The rules have shifted several times in recent years as temporary enhancements were added and expired, so use the official calculator rather than an old article's numbers.
If you have insurance through work
Keeping the same job (remote, or transferring)
- Tell HR before the move and give them the new address.
- Ask whether your plan has a network in the new state. National carriers often do; regional HMOs often don't.
- Ask whether the move lets you switch to a different plan mid-year. A change of residence that affects your plan options often allows it, within a short window set by the plan, frequently 30 days.
Changing jobs as part of the move
- Ask your current employer exactly when coverage ends (often the last day of employment or the end of that month).
- Ask your new employer when coverage starts. Some start on day one; others make you wait a month or more.
- Bridge any gap with COBRA or a Marketplace plan. Losing job-based coverage is its own qualifying event, also with a 60-day window.
If you're the partner moving without a job lined up, our job search guide and career considerations cover the timing.
COBRA vs. a Marketplace plan between jobs
COBRA lets you keep your former employer's plan, typically for up to 18 months. You pay the full premium (the employer's share and yours) plus up to a 2% admin fee, which is often a shock.
COBRA works when
- you're mid-treatment and need the same doctors
- you've already met this year's deductible
- you only need a month or two until new job coverage starts
- the plan has a national network that covers your new state
A Marketplace plan is usually better when
- you qualify for premium tax credits
- the COBRA plan has no network where you're moving
- you need cover for many months
- your deductible would reset anyway
One useful quirk: you generally have 60 days to elect COBRA, and coverage is retroactive to the day your old coverage ended. That means you can sometimes wait, see if you need care, and elect only if you do. Read your COBRA notice carefully before relying on that; the premium for the whole period still has to be paid.
If you're on Medicaid or CHIP
- Medicaid does not transfer between states. Close the old case and apply in the new state as soon as you have an address there.
- Most states have expanded Medicaid to adults with incomes up to 138% of the federal poverty level, but not all. Moving from an expansion state to a non-expansion state (or the reverse) can change your eligibility entirely.
- If you don't qualify in the new state, you'll be able to use the special enrollment period for a Marketplace plan instead.
- Stock up on prescriptions before the old coverage ends.
If you're on Medicare
Original Medicare (Parts A and B) works nationwide. Medicare Advantage and Part D drug plans are regional: if you move out of your plan's service area, you get a special enrollment period to switch. Update your address with Social Security, which handles Medicare enrollment records.
Special situations for couples
Under 26 on a parent's plan
You can stay on a parent's plan until 26 wherever you live, but the network may not cover your new state except for emergencies. Check before relying on it.
Getting married
Marriage is a qualifying life event with its own 60-day window. Many couples who close the distance marry within the year; compare one family plan through the better employer against two individual plans. Our guide to combining finances covers the wider money conversation.
A partner arriving from abroad
Someone moving to the US from another country usually qualifies for the moving special enrollment period without needing prior coverage. Many people with lawful immigration status, including fiancé(e)s on a K-1 and new green card holders, can buy Marketplace coverage, but subsidy eligibility for some immigrant categories has been narrowed by 2025 federal legislation with changes phasing in. Check HealthCare.gov's coverage for immigrants page and get help from a free local assister if the status is unusual. See also our K-1 visa guide.
Pregnancy or ongoing treatment
Get records and a referral from your current doctors before you leave, and choose a plan by checking the specific specialists and hospital you'll need. Pregnancy can also make you eligible for Medicaid in many states at incomes above the usual limits. Our guide to pregnancy in a long-distance relationship has more.
How to compare plans in your new state
| Term | What it is | Why it matters after a move |
|---|---|---|
| Premium | Monthly cost | Varies a lot by ZIP code and age |
| Deductible | What you pay before the plan pays most costs | Usually resets when you switch plans mid-year |
| Out-of-pocket maximum | The most you'll pay in a year for covered in-network care | Your real worst case |
| Network | Doctors and hospitals covered | Check your new doctors, not your old ones |
| Formulary | Covered prescriptions | Search your exact medications |
Metal tiers on the Marketplace trade premium against costs when you use care: Bronze (cheapest monthly, highest costs when used), Silver (middle; the only tier with extra cost-sharing reductions if your income qualifies), Gold and Platinum (higher premiums, lower costs at the doctor). If you use a lot of care, a higher tier often costs less over the year.
A no-gap timeline
- 6–8 weeks before: call your insurer and HR; ask what happens at the new address. Preview plans in the new ZIP code.
- 4 weeks before: book last appointments, refill prescriptions (ask for a 90-day supply), request medical and vaccination records.
- Up to 60 days before: enroll in the new state's plan if you're on the Marketplace, with a start date of the month you move.
- Moving week: keep insurance cards and a medication list in your carry-on.
- First 2 weeks after: confirm the new plan is active; cancel the old one effective the day before; find a primary care doctor and pharmacy in network.
- By day 60: the latest point to enroll using the moving special enrollment period.
Mistakes that leave people uninsured
- Cancelling the old plan before the new one is confirmed.
- Missing the 60-day deadline and having to wait for open enrollment.
- Assuming an employer plan covers the new state without checking the network.
- Forgetting to cancel and paying two premiums.
- Leaving income estimates unchanged after a job change, then owing money at tax time.
- Buying a short-term plan without reading it. These aren't ACA-compliant, can exclude pre-existing conditions, and are restricted or banned in some states.
Where to get free help
- HealthCare.gov or your state exchange: plan comparison and applications. Marketplace call center: 1-800-318-2596.
- Navigators and certified assisters: free, unbiased enrollment help; find one through localhelp.healthcare.gov.
- Brokers: also free to you (paid by insurers), useful for comparing, but they may only show some plans.
- Your state's Medicaid agency for eligibility in the new state.
Have Social Security numbers (or immigration document numbers), income information, current insurance details and proof of the move ready. Then move on to the rest of your change-of-address checklist and your new driver's license.
Frequently asked questions
Does my health insurance work if I move to another state?
Sometimes, but usually not fully. Marketplace and Medicaid plans are state-specific, so you need a new one. Many employer plans are regional too. Most plans still cover true emergencies anywhere in the US, but routine care, specialists and prescriptions may be out of network. Call your insurer, give them the new ZIP code, and ask exactly what will and won't be covered.
Can I keep my Marketplace plan if I move states?
No. Marketplace plans are sold state by state, so you report the move, end the old plan, and enroll in a plan in the new state using the moving special enrollment period. You can usually do this up to 60 days before or after the move. Time it so the new plan starts when the old one ends.
Does getting married let me change health insurance?
Yes. Marriage is a qualifying life event, so you generally have 60 days from the wedding to add a spouse to an employer plan or enroll in or change a Marketplace plan. That's useful for couples who close the distance and marry in the same year: it can make sense to time the switch to one family plan around the wedding date.
Can I put my unmarried partner on my health insurance?
Only if your plan offers domestic partner coverage, which some employers do and many don't. It usually requires proof such as a shared address or a domestic partner registration, and the value of the partner's coverage may count as taxable income. Ask HR. Marketplace plans don't let you add an unmarried partner to your household.
