Hospital Bill Dispute in Thailand
What to do when facing unexpectedly high hospital bills in Thailand.
Last reviewed: 2026-06-01 · by Anglo Siam Law Editorial Team · How we research this topic
TL;DR
Hospital bill disputes commonly involve disagreement over fees charged versus services rendered, insurance pre-authorisation gaps, and bill items not previously disclosed. Recourse runs through the hospital's billing review, the Medical Council of Thailand for professional issues, the Consumer Protection Board for excessive charges, and civil court action for refund or damages.

Key Statutes
| Statute | Reference | Note |
|---|---|---|
| Consumer Protection Act | B.E. 2522 (1979) | Consumer Protection Board jurisdiction |
| Medical Facility Act | B.E. 2541 (1998) | Hospital and clinic licensing; complaint mechanism |
| Civil and Commercial Code | B.E. 2466 (1923), §420 | Civil claim for wrongful charges |
Common Mistakes to Avoid
- Paying the disputed amount under pressure to be discharged — recovery is harder after payment.
- Not requesting an itemised bill — line-by-line review is the foundation of any dispute.
- Skipping the insurance pre-authorisation step at admission — most disputes are insurance-coordination disputes.
- Treating verbal cost quotes as binding without written confirmation.
Embassy Assistance
What Your Embassy Can Do
Your embassy can assist with communication and provide referrals. In extreme cases they may provide emergency loans (must be repaid).
Frequently Asked Questions
Can I refuse to pay the bill?
Hospitals can pursue collection. Better practice: pay the undisputed portion, escrow the disputed portion, and proceed with formal complaint.
Who regulates hospital pricing?
There is no uniform price-cap regulator. The Ministry of Public Health publishes guidelines; Consumer Protection Board addresses excessive consumer pricing complaints.
Will my embassy help?
Embassies can refer to lawyers and assist with home-country insurance liaison. They do not negotiate bills directly.
Can I get my passport back if I cannot pay?
Hospitals legally cannot retain passports as security for bills. If this occurs, it is an immediate complaint to the Tourist Police and Consumer Protection Board.
Expected Timeline
Insurance claim: within 30 days. Dispute resolution: 1-3 months.
