Health insurance for Thai visa applications
On this page
Thai immigration rules require health insurance for some long-stay visas, and the requirement has become stricter over time. A policy that satisfies the visa rules is not always the policy that best protects you, so it helps to understand both.
Which visas ask for it
The Non-Immigrant O-A (long stay) visa, for people aged 50 and over applying from abroad, requires health insurance covering the whole stay, with coverage of at least 3,000,000 baht. Thai insurers that participate in the scheme can issue a certificate in the form Immigration expects. Some foreign policies are accepted if they meet the coverage and include the required certificate, but acceptance depends on the embassy.
Extensions of stay based on an O-A visa also require insurance to remain in force. The Long-Term Resident visa has its own insurance requirement, which can alternatively be met by evidence of social security coverage or deposits in some categories. Other visas, including retirement extensions under a Non-O visa, do not currently have the same requirement, but rules change and some embassies ask for cover anyway.
The insurer's certificate
For visa purposes, the insurer usually issues a certificate stating the insured person, the period, and the inpatient and outpatient coverage amounts. Check the name matches your passport exactly and the period covers the whole visa or extension.
What to check in the policy
The cheapest policy that meets the visa rule may leave gaps. Visa rules focus on inpatient cover, while outpatient visits, which happen more often, may not be included. Many policies exclude pre-existing conditions, either permanently or for a waiting period, so declare your medical history honestly on the application. A claim can be refused later if you did not.
Age matters. Some insurers stop accepting new customers above a certain age or raise premiums sharply with each renewal, so the renewal terms deserve as much attention as the first year's price. Look at the hospital network too. Direct billing with hospitals near you saves paying first and claiming afterwards.
A deductible lowers the premium but means you pay the first part of each claim. Medical evacuation and repatriation are usually add-ons for local policies.
Local or international policy
Thai policies are usually cheaper, and the insurer can issue the visa certificate directly. International expatriate policies cost more, often cover treatment outside Thailand and may have higher annual limits.
Several Thai life and health insurers sell individual health plans to foreign residents. Compare at least two quotes on the same terms, and ask each insurer to confirm in writing that its certificate meets the requirement for your visa type.
If you are employed
Employees of Thai companies are usually covered by the social security system, which gives access to treatment at a registered hospital. Many people combine this with private cover. See insurance basics in Thailand.
