The Social Security Office has improved the determination of medical treatment rights for faster and more accessible services.
And would like to inform you of the details of changing hospitals in the case that the hospital does not participate as a social security hospital in 2025 as follows:
- Social Security Hospitals in 2024 announced that they cannot participate as Social Security Hospitals in 2025, 3 locations: CGH Sai Mai Hospital Bangkok, Thepakorn Hospital, Nakhon Pathom Province, and Bangkok Hospital Surat Thani, Surat Thani Province. The office will arrange hospitals for insured persons who choose to use the rights from these 3 hospitals. Therefore, we would like to inform employers that the arrangement of hospitals is in accordance with the regulations of the Social Security Office on the determination of rights to receive medical services according to the Social Security Act, B.E. 2533 (1990), B.E. 2560, Section 11, in the case that a hospital leaves the social security program.
Arrange a hospital within the area of responsibility of the business or the Social Security Office of Bangkok, area/province/branch (for insured persons under Section 39), effective from January 1, 2025 onwards until the insured person ceases to be insured.
- When receiving medical services at a hospital, Thai insured persons must show their national ID card or other cards issued by the government. Foreign insured persons must show their non-Thai nationality ID card or a government-issued non-registration status ID card or a social security card and passport.
- The right to receive medical services occurs only when, within 15 months before the date of receiving medical services, contributions have been paid for not less than 3 months and the insured person can use the rights throughout the insured person’s term.
- Changing hospitals
4.1 Changing annually can be done between December 16 and March 31 of the following year.
4.2 Changing during the year In case of necessity, such as moving residence, moving work place, or proof that the insured person did not choose the hospital by themselves, submit a request to change the hospital within thirty days.
4.3 The insured person can change the hospital through 4 channels as follows:
1) Submit the form for selecting a hospital for receiving medical services (SSO 9-02) at any Social Security Office nationwide.
2) Make a transaction via www.sso.go.th
3) Make a transaction via the SSo Plus+ Mobile Application
4) Make a transaction via the SSO official Line by adding the friend @ssothai
** Every time there is a change of hospital, insured persons under Section 33 who work with employers. The Social Security Office will notify the result of the hospital selection via the employer, and insured persons under Section 39 will be notified by letter or SMS.
- To check the list of social security hospitals, inquire from your employer/website of the Social Security Office www.sso.go.th or hotline 1506. The hospital you request to change must be located in the province where you currently work or reside or a province bordering the said province and have no more insured persons than the Social Security Office specifies.

- For insured persons who do not wish to change their hospital, they can use their rights to receive medical services from the hospital under their original rights until they cease to be insured. In the case of termination of status from being insured under Section 33 or Section 39, they can continue to use their rights for another 6 months from the date of termination.
