Thailand's Social Security Office has released its updated list of participating hospitals for August 2026, detailing which facilities have reached their patient quotas and which are still accepting new registrations.
According to the Thai-language business news outlet Thansettakij, the August update provides a current snapshot of hospital capacity nationwide under the social security scheme.
For expats legally employed in Thailand, this system is a standard part of your payroll. A monthly deduction goes into the Social Security Fund, which entitles you to free medical consultations and treatments at your designated hospital.
What this means for you

While the standard window to change your registered hospital is typically between January and March each year, mid-year changes are permitted if you move to a new residence or change employers. If you fall into this category, this August update directly affects your healthcare options.
Here is what you should do if you need to select or change a hospital this month:
- Verify availability: Not all private or public hospitals have open slots. Popular private hospitals in expat-heavy areas of Bangkok often fill their quotas quickly.
- Consult your HR department: Your company's human resources team will have access to the full, updated August list and can process the registration on your behalf.
- Check alternative locations: If your preferred hospital is marked as full in the latest update, you will need to select a backup facility within your residential or workplace province.
If you are not moving or changing jobs, no action is required. Your current hospital registration remains valid. For specific facility availability, you can also contact your HR representative or the Social Security Office hotline at 1506.
