What Happens If You Get Sick in Thailand? | Social Security, Private Insurance, and Choosing a Hospital

A practical guide for expats, accompanying families, retirees, and students living in Thailand: how the social security system works, who needs private insurance, visa-specific insurance requirements, and a realistic look at hospital costs.

This is Part 6 of the Thai Life and Law series. In Part 5, we covered driving licences and traffic rules. This time, we look at healthcare and insurance in Thailand. The convenience of walking into any clinic with a national health insurance card — as you would in Japan — does not exist here. Illness and injury can strike without warning. Without preparation, you may face an unexpectedly large bill.


1. How Should Foreigners Approach Healthcare in Thailand?

Thailand has three public healthcare systems for its residents:

SystemWho It CoversAvailable to Foreigners?
UCS (Universal Coverage Scheme / “30 Baht” scheme)Thai nationalsNot available to foreigners
Social SecurityEmployees in private companiesYes, including foreign nationals
Civil Service Medical Benefit SchemeGovernment employees and their familiesNot available to foreigners

In practice, foreigners can access Social Security (if employed) or private health insurance.


2. Social Security — Most Expats Are Already Enrolled

How Enrolment Works

Under the Social Security Act B.E. 2533 (1990), all employees working for private companies in Thailand — including foreign nationals — are required to enrol in Social Security. Employers handle registration, meaning many expats are enrolled without having actively signed up themselves.

Contribution Rates (2026 onwards)

PartyRateMonthly Maximum
Employee5% of salary875 THB (based on a 17,500 THB wage ceiling)
Employer5% of salarySame

From January 2026, Phase 1 of a phased increase has begun. The wage ceiling will rise to 20,000 THB from 2029 and 23,000 THB from 2032.

Medical Benefits

When enrolling, you select one designated hospital (contracted hospital). Medical consultations, hospitalisation, and medication at that hospital are covered at no cost to you.

Key limitations:

  • Treatment at non-designated hospitals is self-funded (except in emergencies)
  • Emergency treatment at other hospitals is covered for up to 72 hours (subject to limits)
  • The designated hospital can be changed once per year (mid-December to end of March)

Other Social Security Benefits

BenefitDetails
Maternity (delivery)15,000 THB per birth + up to 1,500 THB for prenatal visits
Postnatal allowance7,500 THB/month for 3 months
Child allowance800 THB/month until the child turns 6
Unemployment50% of salary (resignation) / 75% (redundancy), up to 6 months
Old-age pensionBased on contributions over 15+ years

The Most Important Limitation — Dependants Are Not Covered

Social Security medical benefits cover the insured employee only.

Accompanying spouses and children receive no medical coverage under Social Security. If you have family in Thailand and assume they are covered through your Social Security, they are not. A hospital visit will be entirely out of pocket.

In practice, many expats are enrolled in Social Security but rarely use it — because designated hospitals are often public facilities with long waiting times and limited English, and most expats prefer to use private hospitals through separate private insurance.

Voluntary Continuation After Leaving Employment (Section 39)

If you leave your job, you can switch to Section 39 (voluntary continuation) within 6 months of departure to maintain medical coverage. The monthly contribution is modest. For current rates, check the SSO (Social Security Office) official website.


3. Accompanying Families and Retirees Need Private Insurance

Who Needs Private Insurance?

  • Accompanying spouses and children (not covered by Social Security medical benefits)
  • Retirement visa (O-A / O-X) holders (insurance is a condition of the visa)
  • LTR visa holders (insurance is a condition of the visa)
  • Students (ED visa) (not legally required, but practically essential)
  • Self-employed / freelance workers

Insurance Requirements by Visa Type

VisaInsurance Required?Requirement
Non-Immigrant O-A (Retirement)YesMinimum 400,000 THB inpatient / 40,000 THB outpatient. Must be from a TGIA-approved Thai insurer
Non-Immigrant O-X (10-year retirement)YesSame as above
LTR visaYesMinimum 400,000 THB inpatient / 40,000 THB outpatient
Non-Immigrant B (employment)No legal requirementAuto-enrolled in Social Security through employer
Non-Immigrant ED (student)No legal requirementStrongly recommended
Tourist visaNo requirement

Note on O-A visa insurance: You may encounter references to “USD 100,000 coverage” — but the official requirement set by Thai Immigration and TGIA is 400,000 THB inpatient / 40,000 THB outpatient, and the policy must be obtained from a TGIA-approved Thai insurance company. A foreign policy alone may not be accepted. Always verify current requirements with Thai Immigration or your nearest Thai Embassy before applying or renewing.

International Insurance vs. Thai Local Insurance

TypeKey FeaturesBest Suited For
International Health InsuranceWorldwide coverage, including Japan. Cashless treatment at private hospitalsExpats who travel frequently or return to Japan regularly
Thai Local InsuranceCoverage within Thailand only. More affordable. Often in ThaiLong-term residents, retirees
Travel InsuranceFor short stays only. Not suitable for long-term residenceShort trips, tourism

4. Public vs. Private Hospitals — Costs and Reality

Cost Comparison

ItemPublic HospitalPrivate Hospital (Bangkok)
Outpatient consultationA few hundred THB1,500–3,000 THB
Hospitalisation (per night)Significantly lower20,000–40,000+ THB
Surgery (e.g. appendectomy)Much lower100,000–300,000+ THB
Waiting time1–4+ hoursRelatively short
English-language serviceLimitedGenerally available

Without insurance, a hospitalisation or surgery at a major private hospital in Bangkok can easily result in a bill of several hundred thousand baht or more. Bangkok’s leading private hospitals — Bumrungrad, Samitivej, BNH — offer world-class facilities and care, but at commensurate prices.

Which Should You Choose?

If enrolled in Social Security, you can receive free treatment at your designated hospital (often public). In practice, most Japanese expats use private hospitals through private insurance, given the language convenience, shorter waiting times, and comfort.

If you use a private hospital, always bring your insurance card or cashless treatment certificate. Without coverage, serious illness can create a significant financial burden.


5. In an Emergency — Who Do You Call?

SituationContact
Life-threatening emergency1669 (national emergency number)
Foreigners / tourists1155 (Tourist Police)
Private hospital ambulanceEach hospital’s direct line (paid service)

A note on ambulances in Thailand: Many ambulance services in Thailand are run by volunteer organisations and may take time to arrive. In a serious emergency, going directly to the nearest hospital ER or taking a taxi may be more practical.

Always carry: Your insurance card (or insurance company ID) and your passport.


6. Does Your Company’s Insurance Cover Your Family?

Many expats at Japanese companies are covered under corporate overseas insurance or expat insurance policies. This creates a situation of dual coverage alongside Social Security.

Always check the following:

  • Whether accompanying spouses and children are included in the policy
  • Whether coverage extends to time spent back in Japan
  • Whether cashless treatment at Thai private hospitals is available
  • Whether there will be a gap in coverage upon resignation or return to Japan

A common misconception is: “The company has insurance, so we’re all covered.” In reality, it is not uncommon for accompanying spouses to be excluded from the corporate policy without the employee realising it.


7. Summary — Three Key Points

PointDetails
① Social Security does not cover your familySpouses and children must be covered by separate private insurance
② Some visas require insurance as a condition of entryO-A, O-X, and LTR visas require insurance from a TGIA-approved Thai insurer
③ Without insurance, private hospital bills can reach hundreds of thousands of bahtThink of health insurance not as optional, but as essential infrastructure for life in Thailand

Healthcare standards in Thailand, particularly at Bangkok’s private hospitals, are genuinely world-class. So are the costs. Insurance should not be something you think about after you need it — it should be in place before you arrive, or within the first days of settling in.
