Expat health insurance in Thailand: what your policy won't cover

Most local Thai health policies are renewed at the insurer’s discretion, and most of them stop somewhere between 75 and 80.

That sentence is the whole article. You can buy at 55, pay for twenty years, never claim, and be declined at 76 entirely within the terms you signed — at which point you are uninsurable, because you now have twenty years of medical history and nobody will take you.

This article used to open on a different problem, and that problem has largely gone away. For years the argument was that Thai immigration only required 400,000 baht of inpatient cover, against a cardiac operation at Bumrungrad costing 800,000 to 1,500,000 — a mandated minimum that would not survive one bad afternoon. On 1 September 2022 the O-A requirement was raised to USD 100,000, about 3 million baht, and the gap it described mostly closed.

The renewability problem did not close. It is not in any comparison table, no regulator has fixed it, and it takes twenty years to show up.

Why this matters

Thailand’s private hospitals are genuinely excellent and priced accordingly. A major operation at Bumrungrad or Bangkok Hospital can exceed a million baht. There is no NHS here, no Medicare, and your home country’s national scheme almost certainly stops at the border. A national health card is not an insurance policy and does not satisfy the visa requirement — though note that since 2022 a policy from an overseas insurer does, so this is a rule about state schemes rather than about foreign cover generally.

So the insurance decision is not a compliance exercise. It is the thing standing between you and a bill that could take your house.

Most people treat it as a compliance exercise anyway, because the visa asks for a number and the number is achievable cheaply.

What it actually costs

Less than this article used to claim, and here is why.

Earlier versions of this page carried a table of annual premiums by cover level and a set of monthly figures attached to named insurers. Those numbers have been withdrawn. They were not sourced to any policy schedule or quote exercise, they carried no stated age, deductible, cover level or territory, and a premium quoted without those four things is not a price — it is a shape.

Health insurance in Thailand is underwritten individually. What you pay turns on your age, your medical history, the deductible you accept, whether outpatient is included, and whether the policy covers Thailand, the region or the world. Two applicants of the same age can be quoted figures that differ by a multiple.

What is safe to say, because it is structural rather than numerical: inpatient-only cover is the cheapest tier and leaves most of what actually happens to you uncovered; adding outpatient roughly doubles it; worldwide cover including the United States is the most expensive band in the market by a distance; and premiums rise steeply and permanently with age, so a quote at 55 tells you very little about your cost at 75.

If you want a number, get three quotes for your own age and history. This site has not run that exercise, and until it does it is not going to print a figure that looks like one.

The three exclusions that matter

Everyone reads the benefit limits. Almost nobody reads these.

1. Renewability — the one that ends careers

This is the most important sentence in this article: most local Thai policies are renewed at the insurer’s discretion, annually.

Typical local plans stop accepting new applicants somewhere between 60 and 70. They stop renewing existing customers somewhere between 75 and 80.

Follow that through. You buy a sensible local policy at 55. You pay premiums for twenty years without a serious claim. At 76 your insurer declines to renew — entirely within the terms you signed.

You are now 76, uninsured, and shopping for cover with two decades of accumulated medical history. Every new insurer will either decline you or exclude everything you might realistically claim for. You have spent twenty years buying protection that expired precisely when the risk arrived.

Guaranteed renewable policies are different: the insurer cannot decline renewal on grounds of age or claims history. The decision to continue stays with you.

Two examples, taken from the insurers’ own published terms rather than from a broker’s comparison page:

• Pacific Cross states “policy renewability to age 99 years”, and that all its plans are registered and approved by the Office of the Insurance Commission, which matters for Thai visa acceptance. Its Premier Plus plan is stated to meet the 3-million-baht requirement.
• Cigna Global applies no upper age limit to its international plans, renewal is guaranteed annually, and it states that renewal premiums are not affected by previous claims.

And here is a live demonstration of why you must ask in writing. Pacific Cross’s own site gives its maximum entry age twice, and differently — the plan specification says “Entry Age up to 75 years” while the FAQ on the same site says “a new entry age up to 80”. One of those is wrong, or one of them is a case-by-case discretion described as a rule. If an insurer’s own website contradicts itself on the single number that decides whether it will take you, a comparison table repeating either figure is worth nothing.

Those two features (a high or absent age cap, and guaranteed renewal) are worth more than any benefit limit on any brochure. They are also the two things comparison tables almost never show.

If you read nothing else here: ask every insurer, in writing, at what age they stop renewing. If the answer is a number under 90, you are buying a temporary product for a permanent problem.

And before this reads as a foreigner-protection guide: Thais face versions of the same thing. We have universal coverage, which foreigners don’t, and private cover here runs on comparable renewal logic. The difference is that a Thai family denied renewal at 76 falls back on the state system. You don’t have that floor. Which is precisely why the question matters more to you than it does to me.

2. Pre-existing conditions

Local insurers typically exclude pre-existing conditions outright rather than loading the premium for them. International plans more often apply waiting periods of 12 to 24 months, and some, Cigna among them, will cover outpatient treatment and medication for conditions like hypertension, type-2 diabetes and arthritis.

The practical consequence is brutal and simple: the best time to buy is before you need it, and every year you delay narrows what you can ever get covered. A diagnosis at 58 doesn’t just cost you that condition; it permanently limits which insurers will take you at all.

3. What “outpatient” means, and doesn’t

Inpatient-only policies are cheap because most of what actually happens to you is outpatient. Consultations, scans, physiotherapy, the dermatologist, the six appointments before anyone admits you to anything.

An inpatient-only plan means you pay for all of that. For many people that’s a reasonable trade — self-insure the small stuff, insure the catastrophe. But it should be a decision, not a surprise, and it is very often a surprise.

Also check: dental, maternity, and mental health are excluded from most standard plans as a matter of course, and psychiatric cover in particular is thin across the whole market.

The visa minimum is not a coverage recommendation

O-A applicants must hold insurance covering at least USD 100,000 — about 3 million baht.

This article previously gave the figure as 40,000 baht outpatient and 400,000 baht inpatient. That was the requirement introduced in 2019 and it was superseded on 1 September 2022. It is still printed on a great many comparison pages, including, until this correction, ours.

The correction changes the argument, so here is the argument again. Set 3 million baht against a cardiac operation at 800,000 to 1,500,000 baht and the minimum is no longer derisory — it is roughly two to four times one serious procedure, where the old floor was a quarter to a half of one.

What has not changed is what the number is for. It was set to stop foreigners defaulting on Thai hospital bills, not to decide how much cover you need. Those are different objectives and only one of them is yours. A single bad year — a long admission, a chronic condition, repeat surgery — will pass 3 million, and the figure is a licensing threshold rather than a recommendation.

And the requirement attaches to the O-A specifically. A Non-O extended annually inside Thailand carries no insurance requirement in law, which means a large number of retirees in Thailand hold no qualifying cover at all and have never been asked for any.

Common misconceptions

“I’ll just pay cash, Thai healthcare is cheap.” Thai public healthcare is inexpensive. Thai private healthcare, which is where you will actually go, is priced for medical tourism. A million-baht bill is unremarkable.

“My travel insurance covers me.” Travel policies cover trips, typically capped at 30 to 90 days, and are void once Thailand is your residence. They are also explicitly not accepted for O-A visa purposes.

“My European health card works.” It does not — a state scheme is not an insurance policy with a certificate. A policy from a foreign insurer is a different matter and has been accepted since 2022.

“I’m healthy, I’ll sort it later.” Later is when you are uninsurable. This is the one people regret most.

“Cheaper local cover is the sensible choice.” It often is — for the next fifteen years. Ask what happens in year twenty-one.

What’s changing

Medical inflation in Thai private hospitals continues to outrun general inflation, which means premium rises will keep outpacing your other costs. Budget for real-terms increases every year, not flat renewals.

The regulator, the OIC, has been tightening standards for expat-facing products, which is broadly good news — OIC approval is a meaningful signal and worth checking for.

And immigration requirements have moved before, in one direction. The mandate arrived in 2019 at 40,000 baht outpatient and 400,000 inpatient, and was raised to USD 100,000 on 1 September 2022 — a roughly sevenfold increase in three years. Anyone building a twenty-year plan on today’s threshold should assume it moves again.

Final thoughts

The insurance market here sells on premium and benefit limits because those are the numbers that fit in a comparison table. The two variables that will actually determine whether you are covered when it matters (the age at which your insurer can walk away, and what they’ve quietly excluded from your history) don’t fit in a table, so they don’t appear in one.

Ask three questions of any policy, in writing:

1. At what age do you stop renewing?
2. Is renewal guaranteed regardless of my claims history?
3. Exactly which of my conditions are excluded, and permanently or for a waiting period?

Any broker who can’t answer all three in a straight sentence is not worth using. Any who can is worth quite a lot — this is a market where the product is complicated enough that good advice pays for itself, and bad advice takes twenty years to reveal itself.

The cheapest policy in Thailand is the one that covers you at 78. It is almost never the cheapest policy today.
