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

To get a Thai retirement visa you need health insurance covering 400,000 baht of inpatient treatment.

Cardiac surgery at Bumrungrad costs between 800,000 and 1,500,000 baht.

That gap — between the cover the government requires and the cover an actual illness requires — is the single most expensive misunderstanding in expat life here. Thousands of people are walking around with a policy that satisfies immigration and would not survive contact with one bad afternoon.

And it isn’t even the worst problem with the way most people buy insurance in Thailand. That one 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 — European national health cards are explicitly not accepted for Thai visa purposes.

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

Broad 2026 ranges, before age loading:

In monthly terms the market runs from under $100 to well over $900. Roughly: Pacific Cross around $80–200 a month for Thailand-focused cover, IMG Global $100–250 for international flexibility, Cigna or AXA $150–400 for premium worldwide.

Those numbers are for a healthy applicant in middle age. They are not what you will pay at seventy.

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. Cigna Global’s plans are guaranteed renewable and it accepts applications with no upper age cap. Pacific Cross accepts new applicants to 75 and renews to 99, and is OIC-approved — which matters for Thai visa acceptance.

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

Since 2019, O-A retirement visa applicants must hold insurance covering at least 40,000 baht outpatient and 400,000 baht inpatient.

Set that against a cardiac operation at 800,000 to 1,500,000 baht.

The mandated minimum covers somewhere between a quarter and a half of one serious procedure. It was designed to stop foreigners defaulting on hospital bills, not to protect foreigners. Those are different objectives and only one of them is yours.

Treat 400,000 baht as a form to be filled in, not a level of protection. If your policy’s inpatient limit has a number that starts with 4 and ends in six figures, you are underinsured for the country you live in.

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, and Thai immigration says so in writing.

“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. The insurance mandate arrived in 2019 and the minimum figures have been revised since. Anyone building a twenty-year plan on today’s 400,000 baht threshold should assume it changes.

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.
