What drives the cost of international health insurance in Asia

There is no single price for international health insurance, only a set of decisions that move it. IPMIAsia explains each driver of an international private medical insurance (IPMI) premium for expats in Asia, and how to bring the number down sensibly.

Why there is no single price

Ask five insurers to quote the same expat in Bangkok and you will get five different numbers, sometimes far apart, for broadly similar cover. That is not a sign that one insurer is wrong. It reflects how each prices risk in that country, which hospitals it expects you to use, how it structures benefits and how it underwrites. It is also why a comparison across the market matters more than the headline on any one brochure.

This guide does not quote premiums. Published numbers go out of date quickly and never match your situation. Instead it explains the seven things that move the price, so that when Nomi shows you a ranked list for your details you understand why the plans sit where they do. For a published, country-by-country view of what expats pay, the HealthiNomad Premium Index (September 2026) is the reference we point people to.

Age

Premiums rise with age, because the likelihood and cost of treatment rise with age. Most insurers price in bands, so the jump happens when you cross into a new band rather than every birthday. Children are usually priced lower than adults, and some plans offer family discounts or cover children at reduced rates when a parent is insured.

Two consequences follow. First, the premium you see today is not the premium you will pay in ten years; ask how the insurer's age bands work and whether it guarantees lifetime renewal. Second, a retiree in Thailand or Malaysia will pay more than a thirty-year-old in the same town for the same plan, and should expect it. What a retiree should not accept is a plan that ends at a given age or re-underwrites at renewal.

Area of cover

Area of cover is the largest lever most people can pull. Plans are sold with regional areas such as ASEAN or Asia, worldwide excluding the USA, and full worldwide. Each step up adds countries where treatment is more expensive, and the premium follows.

The USA is the big one. Including it raises the premium substantially because US treatment costs so much more than anywhere else. If you do not live in the USA and would not travel there for planned treatment, excluding it is the single most effective way to lower the cost while keeping cover everywhere else.

Within Asia, a regional area is often cheaper than worldwide excluding the USA, but check what it contains. Some regional areas leave out Singapore or Hong Kong, which may be exactly where you would want serious treatment. Our regional vs worldwide guide explains the trade-off.

Cover level

An inpatient-only plan is the cheapest configuration. It pays for the large, unpredictable events: admissions, surgery, intensive care, cancer treatment and usually day-patient procedures. Adding outpatient cover for consultations, diagnostics and prescriptions adds cost, because those are frequent, predictable claims. Adding maternity, dental and optical adds more.

Within each module, the tier matters too. A higher annual limit, a private room rather than a semi-private one, full outpatient cover rather than a capped benefit, and a higher maternity limit each push the premium up. The honest question is what you would actually use. Many expats in Asia choose a strong inpatient plan and pay for routine outpatient care themselves, especially in countries where a consultation is inexpensive. In Singapore or Hong Kong, where specialist fees are high, outpatient cover is more often worth having. Our inpatient vs outpatient guide covers the decision.

Excess and cost sharing

An excess, also called a deductible, is the amount you pay before the insurer pays. Accepting a higher excess lowers the premium, because you are taking on the small claims yourself. Coinsurance is a share of each eligible bill you pay after the excess, often applied to outpatient claims, and it has a similar effect.

The right excess is one you could pay more than once in a bad year without stress. Check whether it applies once per policy year or to every claim, and whether it applies to outpatient and inpatient claims separately. Some plans waive the excess for treatment inside their network, which can make a higher excess easier to live with. A high excess paired with a high inpatient limit is a common and sensible structure for people who want protection from the big events at a manageable price.

Who is covered

Adding a partner adds roughly a second adult premium at their age; adding children adds less per child, and some plans discount larger families. The structure of the plan can also differ by person. Some insurers allow each family member to choose different modules, so that a parent who travels has worldwide cover and outpatient benefits while a child has regional inpatient cover. APRIL Thailand, for example, allows modules to differ by family member. Ask whether the insurer permits that, because it can trim cost without cutting the cover anyone actually needs.

If one family member has employer cover, decide whether to duplicate it. Two policies do not automatically coordinate; each insurer has rules on how duplicate cover and excesses interact.

Medical history

Your medical history can change the price in two ways. An insurer that underwrites fully may offer cover with a condition excluded, which leaves the premium as standard, or with a loading, which raises it. Under a moratorium the premium is usually standard, but recent conditions are excluded until you have gone a set period without symptoms or treatment. The written offer is what counts, not the indicative quote.

Medical history is also the reason timing matters. A plan bought while healthy is priced and underwritten on a clean slate, and that slate follows you. Our pre-existing conditions guide explains the routes and what to disclose.

Country of residence in Asia

Insurers price by where you live, because that is where most of your claims will happen. The same plan, same age and same area of cover will generally cost more for a resident of Singapore or Hong Kong than for a resident of Vietnam or the Philippines, because private treatment in the first two is far more expensive. Thailand, Malaysia, Indonesia and Japan sit between those poles, and each insurer places them differently.

This has three practical consequences. Enter your true country of residence when you compare; a quote for the wrong country is not a quote. If you are moving within Asia, expect the premium to change at the next renewal when you update your residence. And if you split your time between countries, ask the insurer how it defines residence, because the answer affects both price and validity. IPMIAsia's country pages for Singapore, Hong Kong, Thailand and the rest of the region explain what shapes the cover in each place.

How to lower your premium without hollowing out the cover

1. Exclude the USA unless you genuinely need planned treatment there.
2. Choose a regional area if every country you would be treated in is inside it, including your treatment hub and your home country.
3. Accept a sensible excess that you could pay in a bad year, and check whether it is waived in network.
4. Right-size the modules. Keep the inpatient limit high; be honest about outpatient, dental and maternity.
5. Structure the family so that each member has the modules they need, where the insurer allows it.
6. Buy while healthy so that underwriting is clean and the premium is standard.
7. Compare at every renewal. Premiums and plan value change year to year, and loyalty rarely pays. Switching is easier if the new insurer offers continuation terms.

Nomi applies all of this at once. It compares 20+ insurers for your age, residence, area and preferences, ranks them on real price and shows what each one includes, so you can see the effect of each decision rather than guessing. The Cigna vs Allianz and Allianz vs IMG pages show how two insurers can differ on the same brief.
