Health insurance for moving to Thailand — what the O-A and LTR visas require
There is no single Thai insurance requirement. There are several, they differ sharply, and which one applies to you was decided the moment you chose a route — usually for reasons that had nothing to do with insurance.

What Thailand requires
Three routes, three different answers.
The same country, the same hospitals, and an insurance obligation that ranges from a specified baht minimum to nothing at all depending on the stamp in your passport.
The O-A retirement route
Health insurance is mandatory, and the current floor is higher than most guides say: cover of at least USD 100,000 — 3,000,000 baht — including Covid-19 treatment, for the whole stay (verified 2026-08-01 against TGIA and the Thai embassy instructions). The famous 40,000/400,000-baht figures are the old rule here, filed by TGIA itself under renewals before 1 September 2022 — and the uplift that replaced them applies to the O-A alone.
The LTR route
The Long Term Resident visa asks for USD 50,000 of cover, or current Thai social security benefits, or a USD 100,000 bank balance maintained for twelve months — the BOI's own list, verified 2026-08-01. Dependants need USD 50,000 of cover or a USD 25,000 deposit each. One requirement, three ways to satisfy it.
Everything else
Several other routes into Thailand attach no insurance condition at all, and the in-country Non-O retirement extension is the one that matters: the Immigration Bureau's own criteria confine the insurance requirement to O-A holders — "only for an alien, who has been granted Non-Immigrant O-A Visa" — and ask everyone else for money instead. That is not permission to arrive uncovered. It is the same trap Mexico sets, where an absent requirement gets read as an absent risk.
Which is why "does Thailand require health insurance" has no useful answer. The question that has one is: which route are you taking, and which embassy is handling it.
The application, dated
The rule attaches to the route, and the route has dates.
Five moments where the Thai insurance question is actually decided. Two of them turn on things no Thai government page publishes — processing times, and how evenly an office applies a change — and the page says which those are.
Three to four months out · choose the visa, inherit the rule
Decide which visa you are actually applying for, because the insurance mandate attaches to the route, not the country. The O-A asks for USD 100,000; the O-X asks for 40,000 baht outpatient and 400,000 inpatient from a Thai insurer; the LTR has its own USD 50,000 rule with a deposit alternative; the in-country Non-O retirement route asks for nothing at all — the Immigration Bureau criteria confine the insurance requirement to O-A holders in terms.
Two months out · arrange compliant cover
For the O-A: at least USD 100,000 (3,000,000 baht) including Covid-19 treatment, for the entire stay. Thai and overseas insurers are both accepted — approved Thai insurers are listed at longstay.tgia.org, and a foreign policy needs the official certificate signed and stamped by the insurer. For the O-X the policy must be Thai, and every applicant needs their own certificate. Start early: underwriting at retirement age takes longer than the visa does.
At application · the embassy checks the floor
Submit the policy or certificate with your O-A application. The embassy checks the sum insured and that cover runs the whole stay; travel insurance is not accepted in place of health insurance. Processing times are not published anywhere and vary by post — and so, in our experience, do document preferences. Get your embassy's list in writing.
If an insurer says no · the route the criteria leave open
Immigration Bureau criteria 2.22(6.3) allow an applicant refused cover, wholly or in part, to substitute money: a 3,000,000-baht deposit held at least two months, or a deposit plus other insurance totalling 3,000,000 baht, supported by a certified letter of denial from the insurer. Worth knowing before a decline letter reads as the end of the plan.
Before extension · the old figures are gone
The old 40,000/400,000-baht renewal standard no longer applies to the O-A. The two primary sources disagree on the date — TGIA files it under renewals before 1 September 2022, while the Ministry of Public Health guideline puts the extension changeover at 1 October 2022 — but either way extensions now sit under the 3,000,000-baht regime. Offices are reported to apply the change unevenly; that variance is not something any Thai government page documents, so ask your office in writing what it will accept before your policy renews.
Where you will actually be treated
Plan for the private system.
Thailand’s private hospitals are the reason a great many people are comfortable moving there. They are genuinely good, they are used to international patients, and they are priced accordingly.
Public hospitals exist and are heavily used, but the axis is employment, not residence. The Ministry of Labour brings foreigners working legally into social security on equal terms with Thai workers; the Universal Coverage Scheme is built for Thai nationals. Residents who do not work here sit outside both, so assume you are planning for private care, because you are.
That has a consequence for how you read the visa minimums. A threshold designed so the country is not left with an unpaid bill is not a considered view of what a serious admission costs at the hospital you would actually choose.
The useful exercise is small and nobody does it: price the cover you would want if something went badly wrong, then check whether it also happens to clear your visa threshold. Almost always it does, and you have stopped optimising for the wrong number.
| Route | Insurance rule | The note that matters |
|---|---|---|
| Non-Immigrant O-A (embassy) | USD 100,000 / 3M THB, incl. Covid-19 | whole stay; Thai or foreign insurer; certificate for foreign policies |
| O-A renewals | 3M THB regime since 2022 | the 40k/400k figures are historical here — TGIA says 1 Sep 2022, the MPH guideline 1 Oct 2022 |
| O-X (5+5 year) | 40,000 THB outpatient / 400,000 inpatient | per policy year, Thai insurer, whole stay; every applicant needs their own certificate |
| Non-O retirement (in-country) | No insurance mandate | the criteria confine insurance to O-A holders; 800,000 THB on deposit or 65,000 THB monthly income instead |
| If an insurer declines you | THB 3,000,000 deposit substitute | held two months, with a certified letter of denial — criteria 2.22(6.3) |
| LTR (all four categories) | USD 50,000 cover | or Thai social security, or USD 100,000 held twelve months |
| LTR dependants | USD 50,000 cover each | or a USD 25,000 deposit per dependant |
Verified against TGIA, the Department of Consular Affairs, the Immigration Bureau criteria, the embassy instructions and the BOI — 2026-08-01, extended 2026-08-16. Every row now rests on a primary text.
Who this page is for
Four situations, four different checks.
The 62-year-old applying for an O-A from Europe
Your policy must cover the full year at USD 100,000 including Covid-19, and premiums at 62 with any history are substantial. Before paying the visa fee, get the insurer's written confirmation that it will issue the stamped Foreign Insurance Certificate — and if an insurer declines you outright or excludes a condition, the criteria let you substitute a 3,000,000-baht deposit held two months, with a certified letter of denial. A decline is not the end of the application.
The existing O-A holder facing extension
You entered under the old 40k/400k regime; that standard has ended for renewals — TGIA dates the change 1 September 2022, the Ministry of Public Health guideline 1 October 2022 — and offices are reported to apply it unevenly. Ask your immigration office in writing which figure it requires before you renew the policy.
The remote worker weighing the LTR
The USD 100,000 deposit can replace insurance, but the BOI applies the twelve-month rule strictly. Pull thirteen months of statements and verify the balance never dipped below the line before you apply.
The couple where only one spouse qualifies
TGIA notes an ineligible spouse is considered for a category O visa instead, with the marriage certificate as evidence — a different insurance position. On the O-X the position is the opposite: spouse and children each need their own Thai policy and their own certificate. Confirm with the embassy which rule applies before buying two policies.
An independent benchmark
Cheap to live in. Not cheap to insure.

- $13,047At 50American national, born 1975
Dearer than Thailand on this measure: Brazil and Mexico. Cheaper: United Arab Emirates and Greece.
Thailand ranks ninth of the fifty — a comparable international plan prices higher here than in Switzerland, Spain, France, Germany or Italy. That reads as an error until you notice what the premium is actually buying: the Bangkok and Phuket hospitals an international policy sends you to serve a medical-tourism market at international prices, and a foreign resident uses almost nothing else. The cost of living and the cost of private care are two different numbers here, and only one of them is low.
One thing the index is not, and its authors say so twice: it does not compare the seven insurers against one another. Where two of them price the same country differently, that reflects different benefits, cover areas and networks — not one being better value. And none of these figures is a quote. They are averages for three people who do not exist, and what you would actually pay turns on your age, your health, your family and where you want to be treated.

All fifty countries, and what the ranking hidesIn Thailand specifically
Three ways this goes wrong, and all three are avoidable.
Choosing the visa first and the cover afterwards
Almost everyone picks a route for reasons that have nothing to do with insurance — age, income, how long they intend to stay — and then discovers what it obliges them to hold. Run it the other way round for ten minutes. Two of these routes ask very different things of you, and the cheaper visa is not always the cheaper year.
Assuming the rule is the same at every embassy
Thresholds and document preferences are applied differently from one Thai embassy to the next, and the one that matters is the one handling your file. No Thai government page documents that variance — this is practitioner knowledge rather than published rule, which is precisely why it catches people. We have watched applicants prepare against a number they read on a forum and meet a different one at the counter. Ask the embassy you are actually applying to, in writing, before you buy anything.
Buying the minimum and calling it cover
The O-A figures are an immigration threshold, not a clinical one. They exist so Thailand is not left with an unpaid bill, and they are not a considered view of what a serious episode in a Bangkok private hospital costs. A policy can clear the rule exactly and still leave you exposed to the events you would most want insured.

How a review works
What a first review actually looks like.
Arranging international cover for the first time, or checking what you already hold — the process is the same, in this order.
The demand intake
Right after you book, we email you a short intake form. Where you are, where you're going, who's coming with you, anything you already hold. It takes a few minutes, and it means the 45 minutes start prepared — with your situation, not with paperwork.
We study your situation
Not products first. Your life first. We look at the country you're moving to and what it legally requires, the country after that if there is one, who depends on you, and where the real exposure sits. We don't quote anything at this stage.
The consultation
45 minutes, by video, in English. Every question you bring gets an answer. We compare the international insurers on how each of them behaves in your situation — underwriting, renewal, exclusions, and what happens on the day a claim is filed. If there is already a policy in force, we go through it clause by clause. Nothing is pitched at the end of it.
Your Private Client Report
One working day later, your Private Client Report arrives — around twelve pages setting out what we found, what we weighed it against, what each option costs, and why we would choose one over the others. What to arrange, what to keep, and where you are paying for something that isn't doing any work. Sometimes the report says: keep what you have. It is yours either way.
45 minutes. By video, wherever you are. Free. Nothing has to change afterwards.
The Cleveland Clinic charges $1,690 for a written second opinion. Ours comes with the review, and there is no fee for it.
The team
The people who'll actually review your situation.
Specialists by topic, not a rota. You'll know who you're speaking to before you book, and you'll speak to the same person again next year.

Book with ChantalThailand questions
What people actually ask us about Thailand.
Is 40,000 THB outpatient / 400,000 THB inpatient still enough for the O-A visa?
No, not for the O-A. Those figures are the pre-2022 O-A standard, and TGIA’s official guideline now lists them only under renewals before 1 September 2022. First-year O-A applicants need cover of at least USD 100,000 (3,000,000 baht) including Covid-19 treatment. The same numbers are still live elsewhere, which is where most of the confusion comes from: 40,000 baht outpatient and 400,000 baht inpatient per policy year remains the current O-X requirement, confirmed against the Department of Consular Affairs and TGIA’s O-X guideline (2026-08-16). If an adviser quotes you a 40k/400k policy for a new O-A application, it will not meet the embassy requirement.
How much insurance does the O-X visa require?
40,000 baht of outpatient cover and 400,000 baht of inpatient cover per policy year — the Department of Consular Affairs O-X page (last updated 30 November 2022) and TGIA’s O-X guideline both state it, verified 2026-08-16. Two conditions travel with it: the policy must come from a Thai insurer and stay in force throughout, and every applicant — spouse and children included — needs a certificate of their own. The USD 100,000 uplift people quote at you belongs to the O-A and does not reach this route.
Why do the old 40,000/400,000 figures still turn up everywhere?
Because the industry’s own reference site still publishes them, mostly without saying when they applied. On 2026-08-16 the pair appeared on three of TGIA’s four guideline pages: the O-A page, correctly labelled "Renewal (before Sep,1 2022)" but carrying no current renewal figure at all, so readers leave with the old numbers; the O-X page, where the figures are genuinely current; and the Special Tourist Visa page, a Covid-era scheme no longer operating, with no historical labelling at all. One page is right, one is honest but incomplete, and one is simply stale.
Can I use a foreign insurer for the Thai O-A visa?
Yes. The embassy instructions accept insurance issued by a Thai or foreign insurance company, provided the sum insured meets the USD 100,000 / 3,000,000 baht floor and the policy covers your whole stay. A foreign policy must be documented on the official Foreign Insurance Certificate, completed, signed and stamped by the insurer. Thai policies must come from the participating insurers listed at longstay.tgia.org.
Does the LTR visa let me skip health insurance?
You can substitute money for insurance. The BOI accepts health insurance of at least USD 50,000, or current Thai social security benefits, or a bank balance of at least USD 100,000 maintained for twelve months. Pull thirteen months of statements before applying — the balance must never have dipped below the threshold — and remember each dependant needs their own USD 50,000 cover or USD 25,000 deposit.
Do I need health insurance for a Thai retirement visa?
For the O-A route, yes — mandatory, with a sum insured of at least USD 100,000 (3,000,000 baht) including Covid-19 treatment, covering your whole stay. That is the current rule per TGIA and the embassy instructions, verified 2026-08-01. The in-country Non-O route carries no insurance mandate at all, and that is a matter of text rather than report: the Immigration Bureau criteria confine the requirement to an alien who has been granted a Non-Immigrant O-A visa, and ask everyone else for funds instead. So the honest answer to "does Thailand require insurance" is that it depends entirely on which visa you are holding.
How much cover does the LTR visa require?
USD 50,000 of health cover — or current Thai social security benefits, or a bank balance of at least USD 100,000 maintained for no fewer than twelve months. That is the BOI’s own list, verified 2026-08-01. Each dependant needs USD 50,000 of cover or a USD 25,000 deposit. The deposit route is checked strictly across the full twelve months.
Will the same policy satisfy every Thai embassy?
Do not assume so. Thresholds and document preferences are applied differently from post to post, and the only answer that counts is the one from the embassy processing your application. No Thai government page documents that variance, so take it as our experience rather than a published rule — and get the requirement in writing first. It is the single most common reason we see a Thailand application stall, and it costs nothing to avoid.
Can I use Thailand's public hospitals?
The axis is employment, not residence. The Ministry of Labour states that foreigners working legally in Thailand have equal rights with Thai people and are brought into social security; the Universal Coverage Scheme is built for Thai nationals. Residents who do not work here sit outside both — no single Thai page states that negative in terms, which is why we say it plainly rather than cite it. In practice it means private hospitals, which are genuinely good and priced accordingly. Plan for the private system, because that is the one you will be using.
What happens to my cover if I leave Thailand?
A Thai domestic policy generally ends at the border, and a policy bought purely to clear a visa threshold is usually a Thai domestic policy. If Thailand is a chapter rather than the destination — or if you spend months a year elsewhere — that changes which policy is right on day one, not at renewal.
How much does international health insurance cost in Thailand?
Comparable international private medical insurance in Thailand costs about $9,854 a year on average, which ranks Thailand 9th of the 50 countries in the SIP Health Cost Index 2025 (data as at August 2025). That is an average across 7 international insurers and three standard profiles — a 24-year-old, a 35-year-old and a 50-year-old — so it describes what the country costs rather than what you would pay. Mexico prices higher and United Arab Emirates lower. Your own premium depends on your age, your health history, whether you are insuring a family, your deductible, and whether you need cover in the United States.
Sources & verification
Where these facts come from.
The headline correction on this page — USD 100,000, not 40,000/400,000 baht — comes from TGIA's own guideline, which files the old figures under renewals before September 2022. An earlier version of this page carried the old numbers; they are now corrected. The scoping matters as much as the number: the uplift applies to the O-A alone, so 40,000 outpatient and 400,000 inpatient remain the current O-X requirement. Part of why the retired figures circulate is that TGIA still publishes them on three of its four guideline pages — correctly on the O-X page, correctly labelled but without a current replacement on the O-A page, and unlabelled on a Covid-era scheme that no longer operates.
