Complete Insurance Guide
Health insurance requirements in Thailand depend entirely on which visa you hold. For some visas it is a legal requirement with no exceptions. For others it is strongly recommended but not legally required. This guide tells you exactly where you stand.

Health insurance has been mandatory for all Non-Immigrant O-A and O-X retirement visa applicants since October 2019. Without valid insurance documentation your visa application will be refused and your annual extension will be denied.
This mandatory insurance requirement applies specifically to the Non-Immigrant O-A and O-X visas, both obtained from a Thai embassy or consulate abroad. It does not apply to the standard Non-Immigrant O visa, commonly used for retirement or marriage extensions processed inside Thailand. If you hold or plan to apply for a Non-Immigrant O rather than an O-A, insurance is not a legal requirement for your extension, though it remains strongly recommended given the same medical cost exposure. Many retirees choose the Non-O route specifically to avoid the insurance requirement, particularly those with pre-existing conditions or age-related coverage difficulties.
For the O-A, the original 2019 rule set a legal minimum of 40,000 THB outpatient and 400,000 THB inpatient per year. Since October 2021 that standard has been raised to a combined 100,000 USD or 3,000,000 THB annual coverage including COVID-19, and this is now what most Thai embassies require. The O-X keeps the original, lower minimum: 400,000 THB inpatient and 40,000 THB outpatient. Always confirm the current figure with your specific embassy before purchasing a policy.
Your policy must be issued by a Thai OIC (Office of Insurance Commission)-approved insurer or an international insurer with the correct certificate format. For foreign insurers you must obtain the Foreign Insurance Certificate form from the TGIA (Thai General Insurance Association) longstay portal at longstay.tgia.org and have it signed and stamped by your insurer. A digital copy or standard policy document alone is not sufficient. The insurance must remain valid for the full duration of your permitted stay.
Insurance premiums increase significantly with age. Age 50–60: typically 25,000 to 80,000 THB per year. Age 65+: typically 60,000 to 150,000+ THB per year. Pre-existing conditions are a major variable, some insurers exclude them entirely, others cover with waiting periods. Understand the pre-existing condition terms before purchasing.
How to Choose the Right Health Insurance in Thailand
Thai OIC (Office of Insurance Commission)-approved insurers are regulated locally, tend to be cheaper, and often include direct billing with major Thai hospitals, but generally offer more limited coverage outside Thailand. International insurers offer broader global coverage and higher claim limits, usually at higher premiums. Some visa categories accept either type, others require a specific one. See the visa-by-visa breakdown above for which applies to your situation.
Inpatient (IPD) coverage pays for hospitalisation and surgery. Outpatient (OPD) coverage pays for consultations, diagnostics and other treatment that doesn't require an overnight stay. Some visa categories require both, others only check inpatient coverage or leave the split up to you. Many expats choose inpatient-only policies to manage costs, since a serious hospitalisation is the larger financial risk. See the visa-by-visa breakdown above for which coverage type your specific visa requires.
A critical variable. Some insurers exclude them entirely. Others cover with waiting periods of 1 to 2 years. A small number of premium insurers cover with full disclosure and a premium loading. If you have significant pre-existing conditions, get specialist advice before purchasing.
Look for a policy with guaranteed renewal regardless of claims history. Some cheaper policies can be cancelled or significantly repriced after a major claim. For long-stay expats, renewal stability is as important as the initial premium.
With direct billing the hospital bills the insurer directly, you pay little or nothing on admission. Without it you pay upfront and claim reimbursement. In a medical emergency the difference is significant. Check whether your insurer has direct billing with hospitals in your city.
Medical costs in Thailand's private hospitals have been increasing 14 to 15% per year. A procedure costing 300,000 THB today may cost 575,000 THB in five years. Factor this into your coverage level decision, the minimum coverage that satisfies compliance today may be insufficient for genuine protection in three years.
Find the Right Health Insurance
for Your Visa and Situation
The right health insurance depends on your visa type, your age, your health profile and your budget. A policy that qualifies for the retirement visa O-A may not be the right fit for a DTV holder. A policy that works at 55 may need reviewing at 65.
