Travel insurance vs local health cover: what actually changes when you move
Almost everyone arrives in Thailand on a travel policy, and a good number are still on one three years later. It works until it doesn’t — and the point at which it stops working is rarely convenient.
What travel insurance is actually designed for
Travel cover exists to stabilise you and, if necessary, fly you home. It is priced on the assumption you will be somewhere for weeks, not decades, and that anything long-running becomes your home system’s problem once you are back.
That is a perfectly good product for its purpose. The difficulty is that nothing about it announces when it has stopped fitting your life, and the annual renewal makes it feel like continuous cover when it is really twelve separate short contracts.
Where it stops matching your life
- Ongoing treatment for a condition diagnosed while you live here
- Anything that becomes "pre-existing" at the next renewal — including something first found under that same policy
- Routine and preventive care, which most travel policies exclude outright
- Age limits, which quietly end some policies entirely at 65 or 70
- Maximum trip length clauses, which some policies apply even to residents
The renewal trap, in detail
This is the part that catches most people, so it is worth being precise. Suppose your travel policy covers treatment for a heart problem discovered in March. It pays, and the system works exactly as advertised.
At renewal in January, that condition is now part of your medical history. The new policy year is a new contract, and it will very likely exclude anything related to it. You are now uninsured for the one condition you know you have — and, because you now have that history, a fresh application elsewhere will treat it the same way.
A local policy is not immune to underwriting either. The difference is that it is written as continuing cover for a resident, so a condition arising after the policy starts is a claim during the contract, not a new exclusion at the next renewal.
The direct billing difference
The other practical gap shows up at the admissions desk. Thai hospitals have direct billing arrangements with local insurers: you present a card and the hospital settles with the insurer.
With a foreign travel policy you generally pay in full and claim back afterwards. For an inpatient stay that can mean putting a very large sum on a credit card, in a foreign country, at the worst possible moment — assuming your card limit covers it at all.
When to switch
The practical trigger is intent. Once you expect to be in Thailand for another couple of years, a local policy is usually both better matched to how you will actually use it and, over time, cheaper.
The more important trigger is health. Underwriting looks at your condition on the day you apply, so switching while you are well gives you materially better terms than switching after something turns up. Every year of delay is another year in which something might be found.
If you are over 50, treat this as urgent rather than administrative. Age limits and accumulating history both work against waiting, and they compound.
What to do before you cancel anything
- Get the local policy issued and in force first — never leave a gap between the two
- Check the waiting periods on the new policy, and keep the old one running until they have passed if you can afford the overlap
- Confirm which hospitals near you the new insurer bills directly
- Declare your full medical history, including anything the travel policy has already paid for
A reasonable middle path
Switching is not all-or-nothing. Plenty of expats hold a local policy for living here and keep a cheap annual multi-trip travel policy for holidays elsewhere, which is a sensible combination rather than a duplication.
If you would like someone to read your current policy with you and say plainly whether it still fits, our advisors will do that at no cost — including telling you if you are better off leaving things as they are.
