Thailand medical treatment visas

Official orientation for Thailand medical-treatment e-Visa routes and the distinction between short treatment and longer treatment stays.

Last reviewed: 2026-07-14

What this page covers

The e-Visa portal lists medical treatment both within tourist routes for shorter treatment and as a separate medical-treatment category. The appropriate choice depends on the real treatment plan, expected period and the responsible mission’s current checklist.

Official classification

  • MT for medical treatment of less than 60 days where shown by the applying mission
  • Non-Immigrant O for medical treatment of longer than 60 days where shown by the applying mission
  • A qualifying accompanying family member may need a separate appropriate route

Prepare the application carefully

  • Use the official Thai e-Visa portal to select the live visa category for the passport/travel-document country and current application location.
  • Applicants must be outside Thailand when applying through the e-Visa process. Do not start from an assumption that a visa is available solely because a category appears in a general list.
  • Create the e-Visa account, complete the form accurately, upload the documents requested for that exact route, pay the applicable fee and keep the approval confirmation sent by email.
  • Passport and photograph
  • Hospital, clinic or medical-provider letter describing the treatment and expected period
  • Appointment, treatment-plan, financial or accommodation evidence where requested
  • Relationship evidence for an accompanying dependant where the mission requires it

Visa, entry and stay are separate decisions

Treatment duration, admission and any extension are assessed separately. If the treatment plan changes, obtain current guidance from Immigration and the medical provider before relying on a prior permission.

Activity boundary

This is an informational guide, not medical or legal advice. Do not use a medical-treatment route for unrelated work, study or long-term residence.

Known developments and changes to watch

No category-specific rule change was found in the official sources reviewed for this page on 14 July 2026. Thailand’s Visa Policy Review Committee met on 30 June 2026 and was asked to develop future proposals, but that meeting did not itself create a new visa rule. Only an official notice with an effective date changes the applicable requirements.
