Most people moving to Thailand think about the visa, housing and taxes — and remember health insurance when the bill from a private clinic is already on the table. Healthcare here is excellent, especially in Phuket, but it is paid for and organised as if every patient holds a policy: the clinic asks for the insurance card first and names the price of the procedure afterwards. For a retiree, a digital nomad or a villa owner, the question “which insurance should I buy” is not only about comfort but about the right to stay in the country: for a number of long-stay visas a policy is a formal condition.
This article is a practical guide to health insurance for foreigners in Thailand. We cover what visas actually require (from official documents, with dates), which policy types exist, what drives the price, what insurance does not cover and how to avoid the usual traps — from hidden exclusions to a visa extension refused over an incorrectly prepared certificate. It complements our piece on healthcare in Phuket: that one covers clinics and geography, this one covers money and paperwork. We do not recommend specific insurers or name a “best policy”: the right choice depends on age, diagnoses and where you travel. This is not legal or insurance advice.

1. Why a foreigner needs a policy in Thailand
Thailand’s public healthcare system is designed for citizens and residents enrolled in national schemes. A foreigner on a visa is usually outside it and therefore pays for treatment personally, at the clinic’s price list. Private hospitals in Phuket and Bangkok offer a level of service familiar from Europe and the US, and the price of complex cases (hospital admission, surgery, intensive care, evacuation) can be out of proportion to a family’s monthly budget. We deliberately give no “average bills” here, because they depend heavily on the clinic and the diagnosis and go out of date quickly; use the price list of the specific hospital and ask for an estimate before a procedure.
Insurance does three jobs:
- Financial protection. One serious event can wipe out savings set aside for buying a home. A policy turns a rare but expensive risk into a predictable monthly payment.
- Access to clinics. Private hospitals work with direct billing: you show the card and the clinic invoices the insurer. Without a policy you pay a deposit or the whole bill yourself and then wait for reimbursement.
- A legal basis for staying. For some visas, proof of cover is a mandatory document at application and at extension.
For anyone considering a property purchase there is a fourth argument: if you plan to spend a significant part of the year in Phuket, a medical policy is a budget line just like the CAM fee and utilities. Compare it with the rest of the cost of life on the island — more in our piece on the cost of living in Thailand.
2. What visas require: O-A, LTR, DTV, tourist entry
Requirements depend on the visa type and the country of application, and Thai rules change. Below is a summary from official documents as of the publication date (14 November 2026); before applying always check your embassy’s instructions and the thaievisa.go.th portal.
| Status | Medical cover requirement | Source |
|---|---|---|
| Non-Immigrant O-A (long-stay, 1 year, applied for abroad) | A policy or foreign social insurance covering all medical expenses, at least USD 100,000 (THB 3,000,000); in force since 1 October 2021 | Guideline of Thailand’s MFA and Ministry of Public Health |
| LTR (Wealthy Pensioner, Wealthy Global Citizen and other categories) | Insurance of at least USD 50,000, or participation in Thai social security, or a USD 100,000 deposit for 12 months | ltr.boi.go.th |
| Non-O on a retirement basis (extension inside Thailand) | Not always formally mandatory, but some immigration offices ask for a policy | Immigration office practice |
| DTV | Check the current document list on thaievisa.go.th | e-Visa portal |
| Visa exemption / tourist entry | Not formally required, but strongly recommended | — |
O-A: what changed. Originally (from 31 October 2019) the O-A required a policy with cover of at least THB 40,000 outpatient and THB 400,000 inpatient. Later the Cabinet approved (15 June 2021) a new version: a Thai or foreign policy, or foreign social insurance, covering all medical expenses of at least USD 100,000 (THB 3 million) is accepted; the change applies from 1 October 2021. Both figures still circulate in articles and forums — that is not an error, just two versions of the rule. We follow the official guideline linked in the sources, but the final word always belongs to the embassy where you apply.
A foreign policy. If you buy insurance outside Thailand, under the same guideline the certificate must be certified: either by an embassy in Thailand or through the foreign ministry of your country with notarisation of the signatory. This is the step most often forgotten and the one that costs weeks.
The retirement visa. For age, bank balances and reporting see our retirement visa guide. For the LTR and its tax effects, see the articles on the LTR visa and LTR tax benefits.
3. Policy types: international, Thai, travel
The market for foreigners splits into several products, and confusion between them is the main source of unpleasant surprises.
| Type | Who it suits | Pros | Cons |
|---|---|---|---|
| International policy (IPMI) | Residents for years, families, frequent travellers | Broad cover, choice of treatment country, evacuation, direct billing at private hospitals | More expensive; needs a transparent application; a certified certificate is needed for the visa |
| Thai policy for foreigners | Those who need a local product for a visa, including the O-A | Baht billing, local support, products tied to visa requirements | Cover limited to Thailand; age limits; its own exclusions |
| Travel insurance | Short trips, visa-exempt entry | Cheap, fast | Low limits, chronic-condition exclusions, does not meet visa requirements of THB 3 million |
| Group / corporate | Employees of local companies | Low price, no application | Tied to the employer and disappears with the job |
| Foreign national insurance or social scheme | Citizens of countries where it works abroad | Familiar terms | Often not recognised by visa rules without certification |
The list of Thai insurers through which an O-A policy can be arranged is given in the official guideline (it names 16 companies and the longstay.tgia.org platform); the market regulator is the Office of Insurance Commission. We do not rate or compare these companies: the list is useful as a check that the chosen product is actually recognised by the visa rules.
A practical rule: travel insurance is for holidays, international insurance is for living. If you spend more than three or four months a year in Thailand, look at an international or Thai residents’ product rather than an extended “tourist” one.
4. What drives the price of a policy
We do not publish an “age — premium” table: insurers’ tariffs change, differ by terms and are meaningless without an application. Our internal 2026 rule of thumb is roughly USD 100–300 per month per adult (an estimate of spending, not any company’s tariff; higher for a family of two adults with children). Instead of ranges, here are the factors that move the price most.
- Age. The strongest factor. Premiums rise with age, usually in jumps at age-band boundaries, so the cost at 59 and at 60 can differ noticeably. Ask the insurer how the premium is recalculated at renewal.
- Cover limit. An annual limit of USD 100,000 and one of several million are different products. The O-A needs at least THB 3 million under the official rule; many buy more for personal safety.
- Geographic cover. A “worldwide excluding the US” policy is cheaper than “worldwide”. If you are treated only in Thailand and Asia, this option saves money.
- Deductible and co-payment. A high deductible lowers the monthly payment but turns small claims into out-of-pocket costs. Co-payment is the percentage you pay on each bill.
- Outpatient block. Doctor visits, tests and medicines are often a separate option. Without it the policy covers inpatient care only.
- Medical history. Chronic diagnoses raise the price, add exclusions or lead to refusal.
- Payment method. Annual payment is usually cheaper than monthly.
To compare offers fairly, ask each insurer for a quote on the same application with identical parameters: age, limit, deductible, geography, outpatient, waiting period.
5. What insurance covers and what it does not
Terms differ by product, but the structure of exclusions is fairly typical.
| Usually covered | Often excluded or limited |
|---|---|
| Inpatient treatment, surgery, room and intensive care | Pre-existing conditions |
| Emergency care and ambulance | Routine dental and optical |
| Diagnostics and tests as part of treatment | Pregnancy and childbirth (waiting period, separate option) |
| Prescription drugs (with an outpatient block) | Cosmetic and aesthetic procedures |
| Evacuation and repatriation (in international policies) | Extreme sports and riding a motorbike without a licence |
| Cancer and chronic conditions that arise after the policy starts | Preventive check-ups and vaccination without a separate option |
A word on motorbikes. In Phuket, injuries after motorbike accidents are a frequent reason for hospital visits. Many policies refuse to pay if the rider did not hold a valid licence of the right category; for details on licences and rentals see driving licences and car and bike rental. Insurance does not replace a helmet and a licence, and a missing licence can cost you the payout exactly when you need it.
6. Age 70+ and chronic conditions
For retirees this is the most sensitive question. The official O-A guideline directly describes the problems that arose under the first version of the rule: foreigners over 70 could not buy a Thai policy, which cost them the right to extend; a foreign certificate did not always fit the local system; and those extending the visa had to buy a policy again. So the new version introduced two mechanisms:
- the option to submit a foreign policy or social insurance with certification;
- for “risk groups” that an insurer fully or partly refused, a refusal letter plus documents showing assets, a bank deposit, insurance or other cover of at least THB 3 million in total under criteria set by the Immigration Bureau.
In practice: if you are over 70 or have a serious diagnosis, do not put insurance off. The older you get and the longer your medical history, the narrower the choice. If you are still planning the move, take out an international policy at a younger age and keep it continuous: many products preserve terms with uninterrupted renewal, while a fresh application at 68 may bring exclusions or a refusal.

7. How to choose a policy: a seven-question checklist
Before paying, put these questions to the insurer or broker and get the answers in writing.
- Is the policy recognised by your visa? For the O-A and LTR — does the amount match the official minimum and is the required certificate available.
- What are the pre-existing condition exclusions? What happens if a diagnosis is made before the policy starts but you did not know about it?
- Is there direct billing at the clinics you use? The list of hospitals in Phuket and Bangkok the insurer has contracts with.
- What is the limit per year and per event? Are there sub-limits on room, surgery, cancer care, intensive care.
- How is the price recalculated at renewal? Increases by age and by portfolio “loss ratio”.
- What about emergency evacuation? Is transport to Bangkok or another country included.
- How is a claim filed and how fast is it paid? Online portal, a hotline in a language you speak, reimbursement time.
And two tips on documents. First, keep the policy, certificate and summary on your phone and on paper — the hospital desk and the immigration office will ask for both. Second, keep your correspondence with the insurer about existing diagnoses — in a payout dispute it often decides the outcome.
8. Traps: where expats lose money and visas
- A travel policy “for the visa”. A cheap travel product often fails the minimum for the O-A or LTR. The result is a refusal by the embassy or immigration office and lost time.
- An outdated figure. An embassy or consultant quotes THB 40,000 / 400,000 although the current version of the guideline needs at least THB 3 million for the O-A. Always check the date of the document.
- An uncertified foreign certificate. Without certification (embassy in Thailand, or your country’s foreign ministry plus a notary) the document may be rejected.
- Hidden exclusions. “THB 3 million cover” does not mean everything is covered: sub-limits on rooms, cancer care and pre-existing conditions can cut the real payout several times over.
- A gap in cover. Skip renewal for a couple of months and a new application at an older age brings a higher price or exclusions.
- Treatment “through a friend”. A clinic outside the insurer’s network means paying out of pocket and waiting for reimbursement.
- A motorbike without a licence. An injury claim can be rejected without a valid licence — see our piece on driving licences in Thailand.
- Mixing up insurances. Insurance of the building, the common areas or the rental pool is not health insurance. More in section 10.
- Buying from an intermediary without checking. Ask for the contract and policy number and check the insurer in the register of the regulator, the OIC.
9. Mini case: a couple in their 60s buying a studio by the sea
An illustrative scenario (generalised, not a real transaction and without real insurer prices). A couple from Europe, both just over 60, are looking at a studio in Phuket for winter stays and applying for the retirement O-A. They plan to spend most of the year in Thailand and therefore consider an international policy with cover of at least THB 3 million to meet the O-A rule.
Step by step:
- They prepare an application with an honest list of diagnoses (one has controlled hypertension) and ask for three quotes on identical parameters: limit, deductible, “worldwide excluding the US”, outpatient block included.
- They check each product against the official O-A guideline: the minimum amount, certification of the foreign certificate, validity no shorter than the visa.
- They read the pre-existing condition exclusions and ask for written confirmation of how hypertension will be treated.
- They pick the option with a slightly higher deductible but with direct billing at the two hospitals nearest their home and evacuation included.
- They put the premium in the annual budget alongside the CAM fee and utilities, so that real yield and ownership costs are counted honestly.
The lesson: the cheapest quote is not always the winner. Three things decide it — recognition by the visa, absence of critical exclusions and direct billing where you actually get treated.
10. Insurance and Phuket property: what is linked and what is not
Buying a home gives neither a visa nor medical cover, and conversely insurance does not raise the value of a property. But two practical points connect the topics.
Distances to clinics. For owners and tenants near Layan beach, the catalogue gives a travel-time guide: from Layan Green Park to Bangkok Hospital Phuket is about 25 minutes by car, to HKT airport about 23 minutes. When choosing a district it is worth looking at the map of clinics and in-season travel times. More on districts: Layan and Bang Tao.
Ownership costs. A medical policy is part of the annual budget alongside the CAM fee (in Layan Green Park THB 75/m² per month, in Layan Verde THB 85/m² per month according to the catalogue), tax on rental income and utilities. When calculating investment yield we use a guide of ~8–10% net per year for the rental pool, but that is a target of the developer’s programme, not a guarantee, and it does not include your personal health costs. How to calculate is covered on the ROI calculator page.
Building insurance and the rental pool are not about health. Insurance of the structure and common areas is part of the management company’s costs and covers property. Taking part in the rental pool gives a share of income but does not replace the owner’s policy. If you live in your unit for part of the year (for example the 30 days of own use in the programme), a medical policy is still arranged separately.
Visa and property. Property does not give a long-stay visa; see the article on visas for property owners and the step-by-step guide how to move to Thailand. If you combine a move with a purchase, start with the visa and the policy and only then choose the property.
Conclusion and next step
In one line: in Thailand you need a policy, and for a number of visas it is mandatory — choose it for your visa, age and diagnoses, not for the lowest price.
- Check the current requirements on the date you apply: for the O-A at least THB 3 million under the official guideline, for the LTR insurance of at least USD 50,000 or another permitted option.
- Have a foreign certificate certified if you buy the policy abroad.
- Do not postpone: the older you are and the longer your medical history, the narrower the choice.
- Put the premium in your property ownership budget.
