You are moving
A marketplace plan does not travel with you. Moving is a qualifying event precisely because the plans available to you change with your address.
Marketplace plans are sold by county, through networks built around local hospitals and local doctors. Cross a state line and often just a county line, and your plan is either unavailable or covers nothing near where you now live.
This is why a permanent move is a qualifying life event: not as an administrative courtesy, but because the product you bought genuinely does not exist at your new address.
The window, and its one condition
A permanent move to an area where different plans are available opens a 60-day Special Enrollment Period.
The condition people miss: you must have had qualifying coverage for at least one of the 60 days before the move. Move while uninsured and the move alone does not let you enroll — you would wait for Open Enrollment. There are limited exceptions, including moving from somewhere you were not eligible for coverage.
Moving for medical treatment, or a stay somewhere temporarily, does not qualify. The move has to be permanent.
What actually changes
Three things, and the third is the one nobody expects:
- Which insurers will sell to you. Among the counties on this site the number ranges from 1 to 13. Moving between two such places is moving between two different markets.
- The price. Your rating area changes, so the same person at the same age pays a different amount.
- Your subsidy. The credit is pegged to the benchmark plan in your area. Move somewhere with cheaper benchmark plans and your credit falls too — which can mean a similar net cost despite lower sticker prices. Move somewhere expensive and the credit rises to meet it.
Look up both counties before you go: the one you are leaving and the one you are going to.
Timing it properly
- Before the move: you can report it up to 60 days in advance and pick a plan that starts the day the old one ends.
- Update your address with the marketplace as the trigger. This is what opens the window; it is not automatic.
- Do not cancel the old plan until the new one is confirmed active. Cancelling first creates exactly the gap the 60 days exist to prevent.
- Have proof ready — a lease, mortgage document or utility bill at the new address, plus evidence of the coverage you held before.
If you are moving within a state
Still worth checking. Rating areas are built from counties, so a move across a county line can change both your price and which plans are sold to you, even with the same insurer and the same state exchange. Whether it opens an enrollment window depends on whether different plans are actually available in the new county.
Moving mid-treatment
If you are being treated for something, check the new county's networks for a comparable specialist before you choose a plan rather than after. Network adequacy varies enormously between counties, and a plan that looks equivalent on paper may have nobody near you who does what you need.
