Your Home Country Health System When You Move to Thailand
Reviewed by Greg Berryman, 7 September 2026
None of the five countries this site covers pays for treatment you receive in Thailand. What changes is your standing in the system back home, and the rules differ by country.

Does your home country's health system cover you in Thailand?
No, in all five cases.
Swipe across to see all columns.
| Country | Entitlement once you leave | Getting it back | Watch out for |
|---|---|---|---|
| Australia | Medicare can continue up to five years, for treatment received in Australia only | Full re-enrolment once past five years | Problems can start earlier, tied to card expiry or mail reaching an Australian address |
| New Zealand | Unaffected. Time overseas does not change a citizen's eligibility | Nothing to re-qualify for | Eligibility only helps you while you are physically in New Zealand |
| United Kingdom | Free NHS entitlement ends when you move permanently. No grace period | Returns once you are ordinarily resident again. A visit does not count | You are expected to tell your GP practice so you come off the register |
| United States | Eligibility continues. Medicare simply does not work overseas | Nothing to restore, but dropping Part B risks a permanent late enrolment penalty | Part B costs $202.90 a month in 2026 for cover you cannot use here |
| Canada | Province by province. Ontario needs 153 days present a year, at risk past 212 days away | A further wait once you are back before coverage reactivates | Rules and numbers differ by province. Confirm with your own health ministry |
Does Australian Medicare cover you in Thailand?
Medicare access can continue for up to five years after you leave, according to Services Australia and Smartraveller. That's only for treatment received back in Australia. Medicare has never paid for anything you receive overseas.
Past five years living abroad, Medicare eligibility ends. You'd need to fully re-enrol if you ever moved back. Some people report practical problems earlier than that too, tied to their Medicare card's expiry date or whether mail still reaches an Australian address on file. Treat it as use it or lose it.
Australia's Reciprocal Health Care Agreements cover a short list of countries. Thailand isn't one of them.
Does New Zealand health cover follow you to Thailand?
Genuinely different from Australia, and worth knowing if you're comparing the two. Per Health New Zealand, time spent overseas doesn't affect a citizen's eligibility for publicly funded healthcare. You don't get quietly cut off after a few years the way an Australian does.
The catch: none of it is portable to Thailand. Eligibility means you can use the public system if you're actually in New Zealand. It doesn't pay for anything here. You still need private health insurance for day to day life in Thailand either way.
If you ever do go back for treatment, you shouldn't face the same re-qualification hurdle an Australian would after a long absence.
Does the UK's NHS cover you in Thailand?
The NHS runs on residence, not citizenship. There's no multi-year grace period. Move abroad permanently and free NHS entitlement ends from that point, not five years from now. You're expected to tell your GP practice so you're taken off the register.
Entitlement comes back if you return to the UK to live permanently and re-establish yourself as "ordinarily resident." A short visit home doesn't restore it.
This sits alongside the frozen State Pension, covered on the UK tax and State Pension page. Two separate issues that tend to catch the same people at the same time.
Does US Medicare cover you in Thailand?
Medicare does not work overseas. Three narrow exceptions exist and none apply to Thailand. Your eligibility continues. What you have to keep deciding is whether to keep paying for something you cannot use while you are here.
Part A is usually free and worth keeping regardless. Part B carries a real monthly premium, $202.90 in 2026, for coverage you can't use while you're in Thailand.
Dropping Part B to skip that premium risks a permanent late enrollment penalty if you ever re-enrol after moving back. That penalty follows you for life.
Most long-term expats either keep paying Part B as insurance against changing their mind later, or drop it deliberately knowing they're unlikely to return. Worth a conversation with a Medicare-specific advisor before deciding either way.
Does Canadian provincial health cover follow you to Thailand?
Runs province by province, not nationally, so the exact rule depends on where you're from. Ontario's OHIP is the most illustrative example:
- You generally need to be physically present in the province at least 153 days a year
- You can be away up to 212 days before coverage is at risk
- Go past that without prior approval and OHIP can lapse
- There's a further wait once you're back before it reactivates
Some provinces have also scaled back what little they used to reimburse for care received outside Canada. Confirm the current rules with your own provincial health ministry directly rather than assuming it behaves like Ontario's, the numbers and the fine print differ by province.
What else changes when you move to Thailand
Banking access and voting rights also change for some of these countries once you are classed as living abroad long-term. Worth looking into if either matters to you. Not something this page covers yet.
What to sort before you leave
None of it is a reason not to move.
Most of it doesn't need sorting before you leave. A lot of it is a phone call or an email away once you are here, settled, and sure you want to stay:
- Updating your address with your bank
- Telling your GP practice you have moved, if you are in the UK
- Checking where you stand with your own country's health system
There is no rush on any of it, and some are easy to do and slow to reverse. Coming off an NHS register and dropping Medicare Part B are both in that category. If there is any chance you will go back, leave them until you know.
The real exception is an International Driving Permit, which only your home country can issue. That one genuinely has to happen before you go.
