O-A Visa Insurance: The 3,000,000 THB Requirement Explained (+ O Route)

O-A Visa Insurance: The 3,000,000 THB Requirement Explained (+ O Route)

The Non-Immigrant O-A visa requires health insurance with a minimum ฿3,000,000 (USD 100,000) total coverage limit, covering both outpatient and inpatient treatment, from an OIC-approved insurer (Thai or foreign). The older "฿40,000 outpatient / ฿400,000 inpatient" split you still see quoted online is outdated framing — immigration and the Thai General Insurance Association (TGIA) now check against the single ฿3M total figure. If you'd rather skip this mandate entirely, the in-country Non-O retirement route doesn't carry it, which is exactly why so many retirees over 60 use it instead.

Baht figures below are quoted first, with USD in parentheses at the site's standing anchor of ฿33/USD (rates move; this is a July 2026 snapshot).

Quick answer

• O-A insurance minimum: ฿3,000,000 (~$90,900) total coverage, outpatient + inpatient combined, from an OIC-approved insurer
• Old framing (still circulating, no longer what's checked): ฿40,000 outpatient / ฿400,000 inpatient
• Who needs it: applicants for the O-A visa, issued at a Thai embassy/consulate abroad before arrival
• Who can skip it: Non-O retirement route, converted or extended in-country — no insurance mandate on that path
• Realistic annual premium: roughly ฿22,900–56,100+ depending on age, before you hit the over-70 availability cliff
• Financial proof (both routes): ฿800,000 deposit, or ฿65,000/month income, or a combination — separate from the insurance requirement

What the 3,000,000 THB rule actually says

The Ministry of Public Health's requirement, administered through TGIA's longstay.tgia.org portal, is that anyone applying for or renewing an O-A visa carries a health insurance policy — Thai or overseas — with coverage of no less than ฿3,000,000 or the equivalent in USD (currently pegged near $100,000) for outpatient and inpatient treatment combined. You need a signed insurance certificate in the TGIA format to submit with your application, and Covid-19 treatment must be included in the policy.

This replaced an earlier two-tier structure that some agents, blogs and even a few insurers still describe: ฿40,000 for outpatient claims and ฿400,000 for inpatient claims. That framing isn't wrong historically, but it isn't what gets checked at the embassy counter now. If an insurer quotes you a plan built around the old split, ask directly whether it also satisfies the current ฿3,000,000 total-limit standard before you buy it — don't assume the two are interchangeable.

Who is actually OIC-approved

"OIC-approved" means the Office of Insurance Commission has cleared the insurer to sell products that satisfy the O-A requirement, and TGIA publishes the current list of participating companies at longstay.tgia.org. Names that regularly show up with dedicated O-A/long-stay products include AXA Thailand (its "EasyCare Visa" plan is built specifically for O-A and O-X applicants, sold with age eligibility up to 80 and renewable to 99), Pacific Cross, Muang Thai Insurance, and a handful of others. Foreign insurers can also qualify if they complete the TGIA overseas-insurer certificate — useful if you'd rather keep an existing international policy than buy a new Thai one, but confirm your insurer will actually fill out that form before you count on it.

Don't shop by headline price alone. Compare what a policy actually pays for chronic conditions, dialysis, cancer treatment and repatriation, not just whether it clears the ฿3M line. See our full rundown on Thai insurers versus international insurers for how the trade-offs shake out.

Premium reality: what this actually costs by age

Advertised "starting from" prices are close to meaningless for this requirement — a young, healthy applicant might see a headline rate under ฿2,000, but the O-A applicant pool skews 50+, and premiums for policies that genuinely carry ฿3M in coverage climb fast with age. Domestic Thai plans in the relevant entry tiers looked like this in mid-2026:

The step-ups cluster hard around age 60, 65 and 70, and most Thai domestic insurers stop accepting new enrollees somewhere between 65 and 70. Wait until 68 to buy your first ฿3M policy and you may find every domestic option closed, pushing you toward international insurers charging $300–950+ a month instead. Buy in your late 50s or early 60s and you usually lock in cover you can renew for life even as the price climbs.

The Non-O route: how retirees avoid this entirely

Here's the part that changes most people's decision. The O-A visa is issued at a Thai embassy or consulate before you travel, and the ฿3,000,000 insurance mandate is baked into that application. The Non-O retirement route — entering on a tourist visa or visa exemption and converting to Non-Immigrant O status at an immigration office inside Thailand, then extending annually — does not carry the same insurance requirement. Both routes still need the same financial proof (฿800,000 deposit or ฿65,000/month income, minimum age 50; see our breakdown of the retirement visa money requirements for the seasoning rules that actually get applications rejected).

That single difference is why the Non-O conversion has become the preferred path for a large share of retirees, especially anyone over 60 staring down the premium curve above. It sidesteps a real, rising annual cost, not a paperwork formality. The trade-off: Non-O is an in-country process, and the conversion mechanics themselves are a process question covered on our sister visa-process site rather than here. If you're weighing O-A against Non-O purely on the money, the insurance line is very often the deciding factor.

For long-term planning beyond either retirement route, the LTR visa financial requirements page covers a separate insurance floor (USD 50,000, or a USD 100,000 deposit alternative) that applies to a different visa category entirely — don't mix the two up when budgeting.

Frequently Asked Questions

Does the O-A visa really require 3,000,000 THB in insurance, or is it 40,000/400,000?

It's the ฿3,000,000 (USD 100,000) total coverage limit as of 2026. The ฿40,000 outpatient / ฿400,000 inpatient split is an older framing that still circulates on blogs and some agent sites, but it isn't the figure immigration and TGIA check against now. If a policy is pitched to you using only the old numbers, confirm in writing that it also clears the current ฿3M total-limit standard.

Can I use my existing international health insurance for the O-A visa instead of buying a Thai policy?

Sometimes, if your insurer will complete the TGIA overseas-insurer certificate confirming ฿3,000,000-equivalent coverage. Not every international insurer does this paperwork, so confirm with your provider before assuming your current policy qualifies.

Does the Non-O retirement visa need health insurance too?

No, not as a visa condition. The Non-O route, converted or extended inside Thailand, does not carry the ฿3,000,000 insurance mandate that applies to O-A. Many retirees choose Non-O specifically to avoid this cost, particularly once they're past 60 and premiums are climbing.

What happens if I can't get insured once I'm over 70?

Most Thai domestic insurers stop accepting new O-A applicants somewhere between 65 and 70, so late entrants are often pushed to international insurers charging roughly $300–950+ a month for comparable cover. Buying a compliant policy in your late 50s or early 60s and keeping it renewed avoids this cliff, since most insurers renew existing policyholders for life even as the price rises.

Is the ฿3,000,000 insurance requirement separate from the ฿800,000 financial proof?

Yes, completely separate. The ฿800,000 deposit (or ฿65,000/month income) is proof you can support yourself financially and applies to both O-A and Non-O. The ฿3,000,000 insurance limit is an additional, insurance-specific requirement that only attaches to the O-A route.

The bottom line

The number to remember is ฿3,000,000 total coverage, not the old 40k/400k split, and it only applies if you go the embassy-issued O-A route. If premiums are the thing keeping you up at night — and past age 60 they should be — look hard at whether the in-country Non-O conversion fits your situation, because it removes this specific cost without touching the ฿800,000 financial requirement at all. Whichever route you pick, buy insurance early relative to the 65–70 enrollment cliff, because the option to buy compliant cover at a reasonable price narrows every year you wait.
