Health Insurance for a Thai Visa: Your Policy Has to Meet the Visa Rules, Not Just Exist

Which visas require insurance

Minimum limits and document formats are set by the Ministry of Foreign Affairs, the Immigration Bureau and the BOI, and they change. Limits for some visa types and filing channels have been revised in recent years. We therefore never rely on figures from old articles; we check the agency notices and the website of the specific embassy you will use on the day we prepare your file.

What we check in your policy

• Outpatient and inpatient limits — stated separately or combined — against what the visa requires
• Whether the policy period covers the full stay requested; a policy ending before the visa is a common reason for requests for further documents
• Whether the policy covers treatment in Thailand; some home-country policies exclude it
• Pre-existing condition exclusions — they do not block the visa, but they matter enormously when you claim
• Whether the insurer will issue the certificate in the format the embassy or agency accepts; some require a specific form
• That the name and passport number on the policy match the passport used to apply

Home-country policy or a Thai policy?

Both can work. If your international policy covers Thailand and the insurer will complete the required certificate, many clients already have what they need and should not buy twice.

The difficulty is that some overseas insurers refuse to fill in Thai forms, or state limits in another currency without separating outpatient from inpatient cover, so the officer cannot verify them. In that situation a separate letter from the insurer, or a policy from a Thai insurer that issues these certificates routinely, is usually the simpler path.

For older applicants, many insurers cap the age for new policyholders and premiums rise with age. Plan before you approach an insurer's age limit rather than waiting until your visa is about to expire.

Travel insurance for Thai citizens going abroad

In the other direction, Thai nationals applying for a Schengen visa need travel medical insurance of at least EUR 30,000 covering treatment and repatriation in every Schengen state for the whole trip. Other countries may not require it but recommend it. We check that the countries, dates and limits match what the embassy asks for; dates that do not match the flight booking are a frequent cause of follow-up requests.

LTR: when you would rather not buy another policy

The LTR visa differs from the O-A in that the BOI rules allow alternatives to a private health policy — for example, showing social security or state medical benefits from your home country that cover treatment in Thailand, or holding a deposit of the announced amount. Each option has its own conditions, and the BOI decides on the documents actually submitted.

In practice, applicants employed by multinationals often already hold an international group policy through their employer. That works if the certificate clearly names the applicant and states the limits, the period and a territory that includes Thailand. We draft the list of details your HR team needs to request from the insurer, so the paperwork arrives complete in one round.

The catch is that group cover ends when employment ends. An LTR holder who changes jobs or retires during the visa term must arrange new cover without a gap and notify the BOI as required.

Spouses and dependent children

Dependants of O-A, O-X or LTR holders usually need their own cover under the dependant visa rules. Being listed on one family policy is acceptable if the certificate shows each person's limits separately. Some insurers issue certificates only for the main policyholder, so ask for individual certificates from the outset.

Children at international schools often also need the school's own accident or health cover. That is a separate requirement from the visa; we check whether existing cover overlaps or leaves gaps.

Before you buy: questions to ask the insurer

None of these answers affect the visa decision, but they directly affect years of life in Thailand. Clients who choose the cheapest policy simply to pass the visa check often discover its limits at the moment they actually need treatment.

• Are hospitals in the province where you will live on the direct-billing network, or will you pay first and claim later?
• How long are the waiting periods for specific conditions after cover starts?
• Up to what age can the policy be renewed, and can the insurer decline renewal after large claims?
• Is there a deductible or co-payment?
• How many days does it take to issue a certificate in the embassy's or BOI's format?

Mistakes that force a re-application

• Buying a policy with a high overall limit that does not split outpatient and inpatient cover as required
• A policy that ends before the requested stay ends
• Relying on an employer's group card when the certificate does not name the applicant
• Submitting only a foreign-language schedule without the required certificate
• Forgetting to renew before the extension date, even though continuous stay requires continuous cover

How we work

1. 1. Identify the visa and channel

   Tell us which visa and where you will file — an embassy abroad or in Thailand. We pull the current insurance rules for that channel.

2. 2. Review your existing policy

   Send the schedule and any certificate; we confirm in writing whether it passes or what is missing.

3. 3. Coordinate with the insurer

   If the certificate needs correcting or a new policy is needed, we liaise with a licensed insurer or broker. You decide and contract with the insurer directly.

4. 4. Add it to the visa file

   We check names, dates and limits against the application and include the documents in the submission.

5. 5. Renewal reminder

   We record the policy expiry alongside your extension date so renewal happens in time.
