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, filed by TGIA itself under renewals before 1 September 2022.
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. 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. ⚑ marks the points that vary by embassy or immigration office — the variance itself is the most stable fact on this page.
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 and O-X carry hard requirements; the LTR has its own USD 50,000 rule with a deposit alternative; ⚑ the in-country Non-O retirement route is widely reported to carry none — confirm that with your immigration office before relying on it.
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. 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 vary by post — and so, notoriously, do document preferences. Get your embassy's list in writing.
Your first year · keep it in force
TGIA states the insurance certificate is strictly required to be presented to immigration, and your permitted stay tracks your cover. A lapse mid-year surfaces at extension, which is the worst possible moment. Diarise renewal at least sixty days ahead so medical questions cannot open a gap.
Before extension · the old figures are gone
Since 1 September 2022 the old 40,000/400,000-baht renewal standard no longer applies; renewals sit under the 3,000,000-baht regime per TGIA. ⚑ Enforcement at individual immigration offices is reported to vary — ask your office in writing what it will accept before your policy renews, not after.
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 access turns on your status rather than your address, and most foreign residents without Thai employment fall outside the scheme. 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 standard since 1 Sep 2022 | the 40k/400k figures are historical — pre-September 2022 only |
| O-X (5+5 year) | Insurance mandated | ⚑ current O-X amounts not yet primary-verified |
| Non-O retirement (in-country) | ⚑ No insurance mandate reported | confirm with your office; the 800,000-baht funds rule applies instead |
| 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 |

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.
The existing O-A holder facing extension
You entered under the old 40k/400k regime; that standard formally ended for renewals on 1 September 2022, and offices apply the change 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. Confirm with the embassy which rule applies to the accompanying spouse before buying two policies.
An independent benchmark
Cheap to live in. Not cheap to insure.

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
Every source worth reading on this says the same thing: thresholds and document requirements vary between Thai embassies, and the one that matters is the one handling your file. We have watched people prepare against a number they read on a forum and meet a different one at the counter. Check 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 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 HansThailand 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. Those figures are the pre-2022 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. If a broker quotes you a 40k/400k policy for a new application, it will not meet the embassy requirement — and much of the internet still leads with the old numbers.
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 is widely reported to carry no insurance mandate — which means the honest answer to "does Thailand require insurance" is: 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 rules vary by embassy, and the only one whose answer counts is the one processing your application. Get their requirement in writing first. This 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?
Access depends on your status rather than your address, and most foreign residents without Thai employment fall outside the public scheme. In practice that means private hospitals, which are genuinely good and are 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.
