Does your health insurance qualify for a Thailand O-A visa?
Probably not, if you bought it at home. The requirement is not just an amount — it is an amount, a scope, and an insurer Thailand recognises. Most rejections come from the third one.
The Non-Immigrant O-A visa — the one usually called the retirement visa, applied for from outside Thailand — will not be issued without proof of health insurance. That part is well known. What catches people is that a policy can meet the money figure exactly and still be refused.
There are three separate tests, and a policy has to pass all three.
The three tests
1. The amount
Current embassy guidance sets the minimum at ฿3,000,000 per policy year, roughly US$100,000 at present rates.
If you are reading older guides you will see a very different pair of numbers: ฿400,000 for inpatient treatment and ฿40,000 for outpatient. Those were the earlier thresholds. They were raised, and a great deal of advice online was never updated. If a page quotes the ฿400,000 figure without a date on it, treat everything else on that page with the same suspicion.
2. The scope
The cover must include both inpatient and outpatient treatment. This is where a lot of otherwise generous policies fail. Plenty of international plans are built around hospitalisation — they will pay for a serious admission but treat a clinic visit as an optional extra. For the O-A that is not enough, however high the headline limit is.
The policy also has to be valid for the whole period of stay, not merely on the day you apply. A twelve-month visa needs twelve months of cover.
3. The insurer
This is the test that catches most people, and it has nothing to do with your policy's quality.
Thailand generally requires the policy to come from an insurer approved by the Office of Insurance Commission (OIC) — the Thai regulator. Your existing plan at home may be excellent, may cover far more than ฿3,000,000, and may still be refused because the company issuing it is not on that list.
Requirements are applied by the embassy or consulate you apply through, and posts differ in how strictly they read them. Confirm the current wording with the specific post handling your application before you pay a premium. A policy bought on the strength of a web page — including this one — is a policy you may not be able to use.
So what actually works
In practice applicants take one of two routes.
Buy from a Thai OIC-approved insurer. The safest path, because the third test is satisfied by definition. Thai expat plans are sold specifically against these requirements, and the paperwork they issue is the paperwork immigration expects to see. Pacific Cross is one of the insurers frequently named in this context; brokers such as Pacific Prime compare several of them.
Use a foreign policy plus certification. Some applicants succeed with an overseas insurer who will issue confirmation in the format Thailand asks for. This is more work, more variable by post, and more likely to end in a second purchase. If you go this way, get written confirmation from the embassy before paying.
What about nomad insurance?
Products aimed at digital nomads — SafetyWing being the best known — come up constantly in this conversation, and it is worth being blunt about them.
They are not built to satisfy the O-A requirement. They are foreign insurers, not OIC-approved Thai ones, so they fail the third test regardless of what they cover. If your plan is an O-A visa, a nomad policy is not the answer.
Where they genuinely fit is a different situation: shorter stays, travel across several countries, or visa routes that do not carry the O-A's insurance condition. If that is closer to your case, they are inexpensive and quick to arrange. If it is not, buying one to satisfy an O-A is money spent twice.

The short version
| Test | Requirement | Where people fail |
|---|---|---|
| Amount | ฿3,000,000 per policy year | Following outdated ฿400,000 guidance |
| Scope | Inpatient and outpatient | Hospital-only international plans |
| Insurer | OIC-approved | Good policy, unrecognised company |
| Duration | Whole period of stay | Cover that expires mid-visa |
Check the insurer question first. It is the one that cannot be fixed by upgrading a plan, and the one that sends people back to the start.
