Pre-existing conditions and international health insurance in Asia

A pre-existing condition does not stop you getting international private medical insurance (IPMI), but it does decide which underwriting route suits you. IPMIAsia explains full medical underwriting, moratorium, CPME and switch terms, and how to read the written offer.

Last updated: 20 October 2026 · Reviewed by IPMIAsia

In short: A pre-existing condition does not stop you getting international health insurance; it decides which underwriting route suits you. Full medical underwriting gives written certainty before you buy. A moratorium is quicker but excludes recent conditions until a symptom-free period has passed, and ongoing conditions never clear it. CPME lets a new insurer carry over your existing exclusions when you switch. The insurer's written offer decides what is covered.

Key takeaways

A pre-existing condition usually means any illness, injury or symptom you had advice, tests, medication or treatment for; a diagnosis is not required.
Outcomes offered are covered as standard, exclusion, restricted cover, a premium loading or declined, and two insurers can reach different outcomes.
Never cancel the old policy until the new insurer has confirmed acceptance, exclusions and the start date in writing.
Non-disclosure, even accidental, is the most common reason a claim is refused or a policy cancelled.
APRIL Singapore publishes a lower age limit for moratorium applications than for FMU, and APRIL Thailand and Singapore both publish CPME forms.

What counts as a pre-existing condition

Each insurer defines the term in its own policy wording, and the definitions are wider than most people expect. A pre-existing condition is usually any illness, injury or symptom for which you have had, or could reasonably have been expected to seek, advice, tests, medication or treatment before the policy started. A diagnosis is not required. Back pain you saw a physiotherapist about, raised blood pressure noted at a check-up, or a scan that was ordered and never followed up can all count.

Related conditions are usually caught too. An exclusion for a heart condition may extend to anything the insurer considers connected. This is why the exact wording of an exclusion matters more than the fact of one. Read the definition in the application and the policy, not a summary.

Full medical underwriting (FMU)

With full medical underwriting you complete a medical questionnaire covering your history, and sometimes that of your family members on the policy. The insurer assesses it and tells you in writing, before you buy, exactly how it will treat each disclosed condition: covered as standard, excluded, covered with a restriction, or covered with a loading on the premium.

The strength of FMU is certainty. You know on day one what is and is not covered, and conditions you disclosed and were accepted are covered from the start. The cost is time and effort: the questionnaire is detailed, the insurer may ask for reports, and the decision can take a while. FMU suits people with a known medical history who want clear terms, and people who would rather know about an exclusion now than discover it at claim time. Most international insurers offer FMU, and some, such as APRIL Singapore, publish an upper age for applying through it.

Moratorium underwriting

With a moratorium you do not declare your history when you apply. Instead the insurer applies a rule: any condition you had symptoms of, or advice or treatment for, in a set number of years before the start date is excluded at first. If you then go a set period without symptoms, advice, medication or treatment for that condition, it can become covered. The periods are set in the policy wording and differ by insurer.

The appeal of a moratorium is speed and simplicity. The weakness is uncertainty: you do not find out whether a condition is covered until you claim, and the insurer then reviews your records. A condition that needs regular check-ups or ongoing medication will not clear the moratorium, because the clock keeps resetting. A moratorium suits people who are healthy, have little history and want cover quickly. Some insurers restrict it by age; APRIL Singapore, for example, publishes a lower age limit for moratorium applications than for FMU.

Continued personal medical exclusions (CPME)

CPME is for people who already hold a policy and want to move to another insurer. Instead of underwriting you from scratch, the new insurer looks at the terms your current insurer applied and agrees to continue them: the same exclusions carry over, and nothing new is added for conditions that arose under the previous policy. You provide your current policy schedule and certificate showing any exclusions, and the new insurer confirms acceptance in writing.

CPME is valuable because it protects the position you built up. A condition diagnosed under your current plan stays covered rather than becoming pre-existing with the new one. Not every insurer offers it, and those that do usually require that your previous insurer and plan are ones they recognise, that cover has been continuous, and that you apply before the old policy ends. APRIL Thailand and APRIL Singapore both publish CPME forms, and several global insurers offer it. Ask for it by name.

Switch terms and changing insurer

"Switch terms" is the broader name for how an insurer treats someone transferring from another plan. CPME is one form. Some insurers instead offer their own underwriting but waive waiting periods for benefits you already held, such as maternity. Others underwrite fully and apply fresh exclusions. The difference can be the whole value of switching.

Before you move, ask the new insurer three questions. Will you accept me on continued exclusions, and from which insurers? Will you waive waiting periods I have already served? What happens to a condition that developed under my current plan? Then compare the written answer against your current policy. Our rule: never cancel the old policy until the new insurer has confirmed acceptance, exclusions and the start date in writing. A gap in cover can break continuity and reset everything.

This matters in Asia because expats move. Someone leaving an employer group plan in Hong Kong, or relocating from Singapore to Thailand, is switching whether they think of it that way or not.

How exclusions apply across inpatient, day-patient and outpatient care

An exclusion for a condition applies wherever that condition is treated. It is worth being clear about the three settings, because plans and exclusions are written around them.

Inpatient means you are admitted to hospital and occupy a bed, usually overnight: surgery, intensive care, a course of inpatient cancer treatment.
Day-patient means you are admitted for a procedure or treatment but go home the same day: day surgery, an infusion, an endoscopy under sedation.
Outpatient means treatment without admission: GP and specialist consultations, diagnostics, physiotherapy, prescriptions.

If a condition is excluded, consultations about it, scans for it, medication for it and surgery for it are all outside the plan, in every setting. Conversely, if you buy an inpatient-only plan, a covered condition is paid for when it needs admission but the outpatient management of it is yours. The two decisions interact: a person with a managed chronic condition that is accepted at FMU may get more from a plan with outpatient cover than from a cheaper inpatient-only one. Our inpatient vs outpatient guide explains the settings in more detail.

The outcomes you may be offered

Outcome	What it means	What to check
Covered as standard	The condition is accepted under normal benefits.	That the acceptance is in writing and names the condition.
Exclusion	Treatment of the named condition, and anything the insurer deems related, is not covered.	The exact wording, how wide "related" is, and whether it can be reviewed later.
Restricted cover	The condition is covered with a limit, a waiting period or a benefit restriction.	The limit, the period and whether it applies per year or for life.
Loading	The condition is covered but the premium is increased.	Whether the loading is permanent and whether it compounds with age increases.
Declined	The insurer will not offer the plan.	Whether another insurer or a different route, such as a moratorium, would accept you.

These are illustrations of how insurers decide, not promises about any named insurer. Two insurers can look at the same history and reach different outcomes, which is a reason to compare terms and not just prices.

Disclosure and preparing to apply

Answer every question accurately and completely. Non-disclosure, even accidental, is the most common reason a claim is refused or a policy cancelled. Gather dates, diagnoses, investigations, medication and treatment for every person on the application before you start. If you are unsure whether something counts, disclose it and let the insurer decide; it is far better than the alternative.

If you take regular medication for a controlled condition such as high blood pressure, asthma or thyroid disease, expect FMU to produce either an exclusion or a loading, and compare the two across insurers. If you have had an operation that resolved the problem years ago, say so; many insurers will accept resolved conditions. Keep copies of the questions, your answers and the written terms you are offered.

Key point: the insurer's written offer decides what is covered, not a comparison result. IPMIAsia and Nomi can organise the options and the routes; they cannot guarantee acceptance or override an underwriting decision.

Nomi will ask about your health as part of the comparison and can connect you with an experienced broker who handles underwriting day to day, which is useful when the history is complicated. Country pages such as Thailand and Malaysia cover the questions retirees with medical history ask most.

FMU: Full medical underwriting: you declare your history and get written terms before you buy.
Moratorium: No declaration upfront; recent conditions are excluded until a symptom-free and treatment-free period has passed.
CPME: Continued personal medical exclusions: a new insurer carries over your existing exclusions instead of underwriting afresh.
Switch terms: The terms an insurer offers to someone transferring from another plan, including CPME and waived waiting periods.
Loading: An increase in premium applied because of a disclosed condition.

Frequently asked questions

Can I get international health insurance with a pre-existing condition?

Usually yes. Most people are offered cover for everything else, with the condition covered as standard, excluded, restricted or loaded depending on the insurer and the underwriting route. Serious or active conditions may be declined by some insurers and accepted by others, which is why comparing terms matters.

Which is better, full medical underwriting or a moratorium?

Neither is better in general. FMU gives written certainty before you buy and suits people with a known history. A moratorium is quicker and suits healthy people with little history, but you only learn whether a condition is covered when you claim, and ongoing conditions never clear it.

What is CPME and why would I want it?

Continued personal medical exclusions means a new insurer accepts you on the same exclusions as your current one instead of underwriting you from scratch. It protects conditions that developed under your current plan. Ask for it by name when switching, and keep the old policy until the new one is confirmed.

What happens if I do not disclose something?

The insurer can refuse the claim or cancel the policy, even if the omission was accidental and even if the undisclosed condition is unrelated to the claim. Disclose everything you are asked about, including things you think are minor, and keep copies of your answers.

I am leaving my employer's group plan in Asia. What should I do?

Apply for a personal plan before the group cover ends and ask whether the new insurer offers continuation terms from your group insurer. If it does, conditions that arose during your employment can stay covered. If it does not, compare FMU offers across insurers rather than accepting the first exclusion.

Does IPMIAsia decide whether I am accepted?

No. IPMIAsia is a free comparison site; Nomi organises indicative options from 20+ insurers and the underwriting routes each offers, and can connect you with an experienced broker. Acceptance, exclusions and the final premium are decided by the insurer in writing after underwriting.
