Health Insurance for Your Thai Visa: Requirements by Visa Type (2026)

If you are planning a long stay in Thailand — whether for retirement, work, or another long-stay visa — health insurance is not optional. For several visa categories, a valid health insurance policy is a formal requirement, and submitting an application without one will result in a rejection. This guide explains which visa types are affected, what minimum coverage is needed, and how to choose a policy that satisfies Thai immigration requirements.

Which Thai visa types require health insurance?

Not every visa applicant needs to show proof of health insurance, but the requirement is significant for those pursuing long-stay status. The main categories where health insurance is mandatory are:

• Non-Immigrant O-A (retirement) visa: the most widely known case, and the most strictly enforced.
• Non-Immigrant O-X (extended retirement) visa: applies the same insurance requirement as the O-A, and in some instances a higher standard is applied at embassies abroad.
• Long-Term Resident (LTR) visa: qualifying applicants under the Wealthy Pensioner and Work-from-Thailand subcategories must maintain suitable health coverage as a condition of the visa.

Holders of standard Non-B (business and work permit), Non-ED (education), or tourist visa / visa-exemption entries are not currently required by immigration to hold health insurance, though the practical wisdom of having comprehensive cover in Thailand is beyond dispute. A separate government proposal to extend a health insurance requirement to tourists and short-term visitors is under Cabinet review as of 2026 but has not been enacted into law.

Minimum coverage for the Non-OA retirement visa

The Non-OA health insurance requirement was introduced in 2019 and has been enforced consistently since. Applicants must present a health insurance certificate or policy document showing minimum coverage of:

• Outpatient (OPD) treatment: at least 40,000 THB per policy year
• Inpatient (IPD) / hospitalisation: at least 400,000 THB per policy year

These are the figures stipulated for insurance purchased through Thai insurers on the official long-stay portal maintained by the Thai General Insurance Association (TGIA). When applying at a Thai embassy abroad, some embassies apply a higher threshold — often stated in USD (commonly referenced as USD 40,000 outpatient and USD 100,000 inpatient, or a combined total that equates to a higher THB figure). Requirements can vary by embassy, so it is essential to confirm the exact standard with the Thai embassy or consulate handling your application.

The policy must be valid for the full duration of the visa period being applied for or extended. A policy that expires mid-term will not satisfy the requirement.

Approved insurers and foreign policies

Thailand accepts health insurance from two sources:

• Thai-licensed insurers: companies registered with the Office of Insurance Commission (OIC) in Thailand and participating in the TGIA long-stay verification portal. Policies from these insurers can be confirmed online by immigration officers.
• Foreign (overseas) insurers: policies issued outside Thailand are accepted provided the coverage meets or exceeds the minimum thresholds. Applicants must supply an official document from the insurer — often an English-language certificate — confirming the coverage amounts.

If you hold an international health insurance policy from a UK, European, or other overseas provider, it may qualify provided it covers treatment in Thailand and meets the coverage minima. International policies from major providers are routinely accepted, but verifying the document format expected by your specific Thai embassy in advance avoids delays.

What a compliant policy should include

When reviewing any health insurance policy for Thai visa purposes, check the following:

• Coverage territory: the policy must explicitly cover medical treatment in Thailand.
• Minimum benefit levels: OPD at least 40,000 THB and IPD at least 400,000 THB (or higher if your embassy requires it).
• Policy duration: coverage must run continuously throughout the visa period. Annual policies that renew within a multi-year extension need to be renewed and documented each year.
• No exclusions that hollow out the core benefit: some policies exclude pre-existing conditions or limit emergency hospitalisation. While blanket pre-existing exclusions are common in travel-style policies, the total IPD benefit available for new events should still meet the threshold.
• Issuing insurer documentation: the certificate must clearly state the insurer’s name, your name, the covered period, and the benefit limits — in a format immigration officers can read.

Premium costs for Non-OA-compliant cover vary considerably with age and the insurer. Thai domestic insurers tend to price lower than international providers but may require medical underwriting. Fees vary — contact us for a current assessment of suitable options.

The tourist insurance proposal: not yet in force

In 2026, Thailand’s Ministry of Public Health announced that it is considering a proposal to make health insurance mandatory for all foreign visitors, including short-term tourists. The rationale is to reduce unpaid medical bills — estimated at tens of millions of THB per year — incurred by foreign nationals without any form of cover.

As of August 2026, this proposal has not been approved by Cabinet, and no entry requirement for tourist health insurance has been enacted. Tourists arriving under visa exemption or a tourist visa are not required to show proof of health insurance at the point of entry. If and when that changes, it will be announced through official channels and widely reported. Gateway Siam will publish a dedicated update.
