Thailand health insurance, compared visa by visa.
Each Thai visa asks for different insurance evidence. Here is what the O-A, O-X and LTR routes ask for, how a Thai and an international policy compare, and what to check before you buy.
In brief
What health insurance does a Thailand O-A visa need?
It depends on the visa. The three routes ask for different evidence:
- O-A, first application: at least USD 100,000 or THB 3,000,000, including Covid-19 treatment, and the insurer’s certificate.
- O-X: THB 400,000 inpatient and THB 40,000 outpatient per policy year, from a Thai insurer, with a certificate for each applicant.
- LTR: USD 50,000 of health cover, Thai social-security benefits, or USD 100,000 held for twelve months. For an extension, ask the office handling your file.
Health insurance for foreigners in Thailand: the four options.
Compare the public arrangement available through your employment, a Thai private policy and international medical insurance. Keep a short trip’s emergency cover separate from a long-term healthcare plan.
| Cover type | When to consider it | Before you choose |
|---|---|---|
| Employment-linked public arrangements | You work in Thailand and qualify under the applicable social-security or health arrangement. | Confirm enrolment, dependants and designated facilities with the employer and responsible scheme. Access to a public hospital is different from insured treatment there. |
| Thai private health insurance | Your treatment needs are mainly in Thailand, or your route calls for a Thai policy. | Check the exact plan, insurer eligibility for your route, hospital network, direct billing, joining and renewal terms, and any overseas benefits. |
| International health insurance | You want a defined area of treatment abroad or expect future moves. | Confirm residence eligibility, medical history, hospital access, evacuation and relocation terms. A high limit alone does not establish acceptable visa documentation. |
| Travel or emergency cover | You need cover for a defined trip and meet that product’s residence and duration rules. | Check routine care, chronic conditions, renewals and long-stay exclusions. Do not assume a travel certificate substitutes for required resident health insurance. |
A useful shortlist starts with your circumstances. We confirm insurer availability for your residence before proposing cover. Compare exact products, accepted medical terms and treatment geography; an insurer’s name or a starting premium is not enough.
We review your route, current policy, preferred hospitals and countries of treatment, then explain suitable cover types and the insurer or authority confirmations needed before purchase.
O-A, O-X and LTR: what each visa requires.
These are route-specific insurance requirements, not a complete visa eligibility checklist. Initial applications and extensions need separate verification.
O-A: the first-year application
TGIA and the Royal Thai Embassy in Vienna state a minimum of USD 100,000 or THB 3,000,000, including Covid-19 treatment. The embassy requires cover for the entire stay and specific insurance documentation. Check the post handling your application before buying.
O-X: a different requirement
TGIA’s O-X guideline specifies THB 400,000 inpatient and THB 40,000 outpatient cover per policy year from a Thai insurer. Each applicant, including a spouse or child, needs a certificate. The O-A figure must not be substituted for this route’s instructions.
LTR: insurance or a qualifying alternative
The BOI lists USD 50,000 health cover, current Thai social-security benefits, or a qualifying USD 100,000 bank balance held for at least twelve months. Dependants have separate evidence requirements. Meeting this condition alone does not establish eligibility for an LTR visa.
Use the current instructions from the body handling your file. A qualifying limit or deposit does not establish how a future hospital bill will be paid.
From application to renewal: what to check when.
Do the policy and visa checks together, then review continuity before a renewal or move.
| When | What it involves |
|---|---|
| Before comparingidentify the route and stage | Write down the precise visa category and whether this is an initial application or an extension. Obtain the current checklist from the relevant embassy, immigration office or BOI; do not treat a general retirement-visa summary as your instructions. |
| Before purchasecheck the policy and evidence | Ask about the required limit, covered period, insurer eligibility and certificate. Then compare underwriting, exclusions and renewal terms. If a condition is excluded, establish its effect on both healthcare needs and the application before paying. |
| Before travelprepare for treatment | Confirm which hospitals can arrange direct billing, what needs prior authorisation and whether a deposit could be required. Save the insurer’s assistance contact and check evacuation destination and approval conditions. |
| Before renewalpreserve accepted cover | Review the new premium, benefits, visa evidence and any proposed change of insurer together. A new quote may involve new medical assessment. Confirm replacement cover before cancelling a policy that already accepts your history. |
| Before another movecheck permission to continue | Tell the insurer your intended residence and treatment countries. Ask which benefits, prices or underwriting terms change. Temporary travel and a permanent move can trigger different provisions. |
Thailand visa insurance requirements, route by route.
Start with any health or social-security arrangement attached to your employment. Confirm the covered people and facilities. Public-hospital access and entitlement to funded treatment are different questions; a person without scheme cover may need to pay.
For private insurance, name the hospitals you would want to use. Ask the insurer about direct billing, preauthorisation, deposits, exclusions and evacuation. Meeting a visa minimum does not answer those questions.
The table separates the primary sources by route. It is a starting point for an application check, not a promise that any named insurer or policy will be accepted.
| Route | Insurance evidence | Scope and source |
|---|---|---|
| O-A first-year application | USD 100,000 or THB 3,000,000 | Including Covid-19; whole-stay and certificate requirements. TGIA and Royal Thai Embassy Vienna. Official guidance |
| O-X | THB 400,000 inpatient + THB 40,000 outpatient | Per policy year; Thai policy and individual certificates. TGIA O-X guidance. Official guidance |
| LTR principal applicant | USD 50,000 health cover, or qualifying alternative | Thai social-security benefits or USD 100,000 bank balance held at least twelve months. BOI conditions apply. Official guidance |
| LTR dependant | USD 50,000 health cover, or qualifying alternative | Thai social-security benefits or USD 25,000 per dependant held at least twelve months under BOI rules. Official guidance |
| Extensions and other categories | Check the exact current route | The initial-application figures above are not a universal extension or retirement-visa checklist. Official guidance |
Confirm the current checklist with the embassy, immigration office or BOI responsible for your application. The O-A USD/THB figures are the stated alternative thresholds, not a currency conversion for pricing a policy.
Four situations, four different checks.
A new O-A applicant
Check the required medical limit and certificate, then compare accepted conditions, renewal age and chosen hospitals. Obtain insurer confirmation about the form before buying; a high limit is only one part of the decision.
A resident considering a switch
Read the renewal offer alongside your existing exclusions and accepted conditions. A cheaper proposal may restart medical assessment. Keep the immigration checklist separate from the insurer comparison.
A remote worker considering LTR
Confirm the whole LTR eligibility route with BOI, including the acceptable insurance or alternative evidence. Then decide whether your healthcare plan is suitable regardless of how you meet the visa condition.
A couple or family
Check each person’s visa and healthcare position. O-X requires individual certificates; LTR dependants have their own evidence rules. Assess children’s care, maternity where relevant and home-country visits under the actual policy.
Cheap to live in. Not cheap to insure.
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.
Dearer than Thailand on this measure: Brazil and Mexico. Cheaper: United Arab Emirates and Greece.

Three ways this goes wrong, and all three are avoidable.
Comparing numbers without the visa category
THB 40,000/400,000 is the published O-X requirement and appears historically on TGIA’s O-A page. Read the route and application stage with the number. Initial applications, extensions and different visa categories need their own checks.
Assuming the insurer will issue the certificate
An international policy can have a large medical limit but still need a specific form signed by the insurer. Obtain confirmation that the required evidence can be issued for your application before committing to a policy.
Buying a threshold instead of a treatment plan
A visa minimum does not tell you whether a condition is covered, whether your chosen hospital can bill directly, or what happens after evacuation. Compare those terms separately, including any deposit or preauthorisation you may need.
Any of these sound like your situation? See 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. We work through the questions that matter in your situation: underwriting, renewal, exclusions and treatment geography. If you already hold cover, we read its wording and personal endorsements. We identify what is clear and what still needs the insurer's written confirmation.
Your Private Client Report
One working day later, your Private Client Report arrives — around twelve pages setting out what we found, the alternatives considered, available cost information, and the reasons for our recommendation. Any missing documents or insurer answers are identified as open questions. 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 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 health insurance: your questions.
Is THB 40,000 outpatient and THB 400,000 inpatient enough for a new O-A application?
TGIA’s first-year O-A guidance and the Royal Thai Embassy in Vienna instead state USD 100,000 or THB 3,000,000, including Covid-19 treatment. TGIA labels the smaller O-A amounts as historical renewal figures. Check the current instructions of the post handling your file, including the required policy dates and certificate.
How much health insurance does the O-X visa require?
TGIA’s O-X guideline states at least THB 400,000 inpatient and THB 40,000 outpatient cover per policy year. It requires a Thai policy throughout the permitted stay and an insurance certificate for each applicant, including spouse and children. These are O-X instructions, not the first-year O-A rule.
Can I use international health insurance for an O-A visa?
The Royal Thai Embassy in Vienna accepts Thai or foreign insurance meeting its stated requirements and asks for the prescribed Foreign Insurance Certificate completed, signed and stamped by the insurer. This is evidence for that application process, not a promise that every international product or certificate will be accepted by every post.
How much health insurance does the LTR visa require?
The BOI lists health cover of at least USD 50,000, current Thai social-security benefits, or at least USD 100,000 in an account in the applicant’s name maintained for no less than twelve months. For a dependant, it lists USD 50,000 cover, Thai social-security benefits or a qualifying USD 25,000 deposit per dependant held for the same period. Other visa eligibility conditions still apply.
Does a deposit alternative provide health cover?
No. Satisfying a visa condition with eligible funds does not create an insurance policy. Separately decide how treatment would be paid for and how much risk you can retain. Confirm the applicable route and evidence with the authority before relying on a deposit alternative.
What should an existing O-A holder check before extension?
Request the current insurance and document checklist from the immigration office handling the extension. TGIA’s public page labels its smaller renewal amounts as applying before September 2022; that historical paragraph is not a complete current extension checklist. Review policy renewal and visa evidence together.
Does every Thai retirement route require the same insurance?
No. O-A and O-X have different published insurance rules. Other visa applications and in-country extensions must be checked under their own current instructions. Do not infer a requirement, exemption or deposit alternative from another category.
Can foreigners use public hospitals in Thailand?
Check both access to a hospital and who pays for treatment. Employment can provide access to a social-security or health arrangement, subject to its conditions and facilities. Residence alone does not confirm enrolment. Someone without scheme benefits may still use a public hospital as a paying patient; private insurance is a separate choice about benefits and access.
What happens to my policy if I leave Thailand?
Check the exact contract’s treatment territory, travel benefits and rules for a change of residence. A Thai policy may include some overseas benefits, while an international policy can still restrict relocation. Ask the insurer to confirm the next country and continuity before moving or replacing accepted cover.
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.
