A lot of people moving around Asia get confused when they start comparing international health insurance. Two plans can look almost identical — same hospital limits, same benefits — but one costs $1,200 a year and the other $4,000+. The main reason is coverage area.

Here’s what’s really going on.

Most international health insurance plans price themselves based on where you are allowed to receive treatment, not where you live.

That means:

• A plan covering Vietnam, Thailand, Malaysia might be relatively affordable
• Add Singapore and suddenly the price jumps dramatically
• Add the US and it becomes eye-wateringly expensive

Why Singapore changes everything

Singapore has some of the most expensive private healthcare in the world. A short hospital stay that might cost:

• USD $1,000–2,000 in Vietnam
• USD $2,000–4,000 in Malaysia
• USD $10,000–20,000+ in Singapore

Insurers know that if Singapore is included, policyholders will go there for big treatments. That forces them to price the whole plan much higher — even if you personally never plan to set foot in Singapore.

It’s the same logic with the US, which is why “Worldwide excluding USA” plans are much cheaper than “Worldwide including USA”.

Typical coverage zones you’ll see

Most insurers offer zones like:

• Asia (excluding Singapore, Hong Kong, Japan) Cheapest option. Designed for people based in places like Vietnam, Thailand, Indonesia, Philippines, etc.
• Asia including Singapore / Hong Kong Big price jump, because these are premium medical hubs.
• Worldwide excluding USA Covers Europe, Asia, Middle East — still reasonable, but pricier.
• Worldwide including USA The most expensive by far.

Why this matters for expats and digital nomads

If you live in Vietnam, Thailand, or Malaysia and are happy to get treatment locally (or fly to Bangkok/KL), you don’t need to pay Singapore-level prices.

But if you want the freedom to go to Singapore’s private hospitals, you’ll be paying for that privilege every year whether you use it or not.

This is why two people living in the same city can have totally different premiums — they chose different coverage zones.

If you’re comparing plans, always check:

• Which countries are included
• Whether Singapore is included
• Whether it’s “Worldwide” or “Asia only”

That one line in the policy often explains 70–80% of the price difference.
