Two policies at the same monthly price can leave you tens of thousands of euros apart on the day it matters. The difference is never in the brochure; it sits in six specific clauses: the annual limit, the area of cover, the deductible, the age caps, how claims are settled, and how increases are capped. Here is how to read each one, and the figure to check every time.
1. The annual limit, measured against local costs
A limit means nothing until you compare it to where you live. In a private Bangkok hospital, a serious admission or an oncology protocol runs into hundreds of thousands of baht. For reference, the Thai O-A visa demands at least 3,000,000 baht of cover, and that is an administrative floor rather than a medical estimate. A policy capped below it clears a counter, not a hospital bill.
2. Area of cover, where the exclusions matter more than the name
"Asia" is not a standard term; every insurer defines its own zones. Quotes gathered for one profile in Thailand included "Asia excluding China, Hong Kong, Japan and Korea", "Asia excluding Hong Kong, China and Singapore", and a zone excluding China, Hong Kong, Japan, Singapore and Taiwan. The excluded names are consistently the region's most expensive medical destinations, and the ones you get evacuated to. Compare exclusion lists, never zone labels.
3. The deductible, a calculation rather than a preference
The right deductible is the one whose annual premium saving exceeds what you would actually pay out. Do that subtraction before choosing. Then check one decisive detail: does the deductible apply per policy year or per claim? With two hospital admissions in one year, the second wording charges you twice.
4. Age caps, at entry and at renewal
Every policy has both, and buyers usually read only the first. Local Thai plans generally stop new applications between 60 and 70, international plans around 74. Renewal typically ends between 75 and 80. The second cap is the one that sets the date you will be left without a solution, and it lives in the policy wording rather than the brochure.
5. Direct billing or reimbursement, visible at admission
With direct billing the insurer settles with the hospital and you advance nothing. With reimbursement you pay first, sometimes several thousand euros, and wait weeks. For a consultation it changes little; for an emergency admission it changes everything. Ask for the network list in your city, not the country.
6. Annual increases, discovered at the second renewal
A low opening premium is a first year, not a price. Ask for three years of increase history on the same product, and check whether the policy caps the rise triggered by moving into a new age band. Without that cap, your budget depends entirely on the insurer's future decisions.
The order to check them in
Start with the age caps: if they exclude you, nothing else matters. Then the area, which governs access to serious treatment. Then the limit, measured against local costs. Deductible, settlement method and increases come afterwards, because they are adjustments rather than eligibility. That order stops you comparing policies you cannot buy.
Frequently asked
What limit should I aim for in Southeast Asia?
Take the cost of a serious admission at the private hospital you would actually use, and check the limit covers it several times over. A visa minimum is not a medical benchmark.
Does direct billing work everywhere?
No, it depends on the insurer's network. A policy can offer direct billing with no hospital in your city attached to it.
Can a pre-existing exclusion be negotiated?
Sometimes, with medical evidence. An age cap never can: it is an underwriting rule, not an assessment.
Local or international insurer?
Local costs less, often accepts later, and covers a narrower territory. International covers wider and follows you between countries. It depends on your plans, not on a ranking.
