Two separate questions get mixed together constantly: "what insurance does my visa require?" and "what insurance should I actually have?" The answers are different, and confusing them can cost a retiree a great deal in premiums over the years.

Question 1 — what the visa requires
| Visa | Insurance requirement |
|---|---|
| Non-O + extensions | None in the published criteria; the 2019 police order on insurance applies to O-A holders |
| O-A | ฿3,000,000 / USD 100,000 total sum insured per policy year, all medical expenses including COVID-19; Thai insurer on the TGIA list or foreign insurer with the Foreign Insurance Certificate; every extension re-checks it — the O-A insurance rule in detail |
| O-X | Mandatory: at least ฿40,000 outpatient and ฿400,000 inpatient |
| LTR | USD 50,000 coverage or USD 100,000 bank deposit held 12 months or Thai social security |
This is why the Non-O or the LTR often suits retirees better: they leave the insurance decision with you, based on your health and wealth — not with a rule written for everyone.
Question 2 — what you should actually have
Realistic premium expectations for comprehensive inpatient cover around ฿3M (2026 market, healthy applicant, typical deductibles):
| Age | Approximate annual premium | The catch |
|---|---|---|
| 60 | ฿50,000–90,000 | Pre-existing conditions excluded |
| 70 | ฿100,000–250,000 | Many insurers no longer accept new applicants |
| 80 | ฿200,000–400,000+ (renewals only) | Renewal not guaranteed after claims with some insurers |
- Buy before 65 if you want lifetime cover. The market largely closes to new applicants at 70–75. Look for policies with guaranteed lifetime renewability — that clause is worth more than a cheap premium.
- High-deductible strategy: a ฿100,000-deductible inpatient policy can halve the premium; you self-insure the small stuff. This is the most popular structure among our financially comfortable clients.
- Self-insurance (Non-O only): legal, and rational above roughly ฿3M of liquid Thai assets — but write the plan down and tell your family where the money is. Pair it with a Thai will and, ideally, a living will.
- O-A renewal risk: if your insurer declines to renew, you need another qualifying policy or the route for people refused cover (the insurer's letter of denial plus evidence worth not less than 3 million baht in total, under Immigration Bureau criteria — the O-A insurance rule). Without one of these, the O-A extension cannot proceed. Moving to a Non-O is possible — how the switch works.
