Medical Treatment Visas for Thailand: What Each Route Allows
The 30-day visa-free rule, the 60-day MT tourist visa and the 90-day Non-O visa compared, with embassy-listed documents and fees and what to check before you book.
If you are flying to Bangkok, Phuket or Chiang Mai for a hospital check-up or a procedure, the length of your treatment decides which visa you need. A quick scan or consultation fits the visa-free stay. A longer course of treatment or recovery may not.
This guide sets out the three routes, using the Thai embassy pages that publish the requirements. Rules differ by embassy and nationality and they change, so treat it as a map, not legal advice.
Visa-free entry: now 30 days
Thailand’s special 60-day visa exemption ended on 15 September 2026. The Phuket Express reported that Interior Ministry notices in the Royal Gazette replaced it with a 30-day exemption. It covers 60 countries and territories, including the EU states, the UK, the US, Canada, Japan, Singapore, Malaysia and India.
A one-time 30-day extension inside Thailand remains available, subject to immigration approval, according to the same report. The exemption covers tourism only. Nationals of other countries need a visa, which they can apply for through Thailand’s e-Visa system.
For a short stay, this is the simplest route. For anything planned around a procedure plus recovery, 30 days can pass quickly, and an extension is at an officer’s discretion.
The MT tourist visa: up to 60 days
The Royal Thai Embassy in Pretoria describes a tourist visa in the MT (medical treatment) category for stays of 60 days or less. It is single-entry and must be used within three months of issue. The embassy lists a fee of ZAR 600.
Its document list includes:
- a letter from the Thai hospital or medical facility stating the medical purpose and treatment duration;
- travel tickets, with the stay not exceeding 60 days;
- proof of accommodation for the whole stay;
- three months of bank statements showing at least ZAR 11,000 per person.
Embassies set their own details. The Thai embassy page for Poland, hosted on the foreign ministry site, asks for a letter from a registered Thai hospital showing your name and appointment date. It lists a fee of 180 PLN and says an immigration officer grants the stay on arrival. Extensions go to the Immigration Bureau in Bangkok and are discretionary.
The Non-O visa: up to 90 days
For treatment longer than 60 days, the Royal Thai Embassy in Washington points to a Non-Immigrant O (medical treatment) visa. It is valid for 90 days, single entry, with a listed fee of US$80.
Applicants apply online at thaievisa.go.th at least 30 working days before travel. The embassy asks for:
- three months of bank statements with a month-end balance of at least US$4,000;
- an appointment letter from the hospital showing your name, date and purpose, signed by an authorised person.
Extensions of stay are requested from Thailand’s Immigration Bureau after arrival, the embassy says. Under-20s need extra family documents, and anything not in Thai or English needs a notarised translation.
What travellers should check
- Which embassy you apply to. Money thresholds, fees and processing times differ, as the South African and US pages show.
- Who accompanies you. The Pretoria page says each family member must meet the financial threshold. Companions travelling on their own visa-free entry are a separate question to confirm.
- The hospital letter. Ask the international patient department for a letter with your name, treatment and expected duration before you apply. Our guide to how hospital accreditation works explains what to look for in a provider.
- Insurance. Treatment abroad is often excluded from travel policies. Our piece on health insurance for long-stay residents covers the basics.
- Recovery time. Ask your surgeon how long you should stay before flying home, then set the visa length around that, not the other way round.
Know before you go
- Where: apply at a Royal Thai Embassy or consulate, or online at thaievisa.go.th
- Price: ZAR 600 (MT, Pretoria), 180 PLN (MT, Poland), US$80 (Non-O, Washington), as listed on the embassy pages in October 2026
- Good for: treatment plans from a few days to about three months
- Check first: your nationality’s status, your embassy’s current document list and the hospital letter
Any procedure, medication or treatment plan is a decision to make with a qualified doctor, who can also tell you how long to stay.
