A pre-existing condition rarely stops you getting international health insurance as an expat. What changes is how the condition is handled: whether it is covered from the start, covered after a waiting period, or left outside the policy while everything else is protected. This guide explains the three routes insurers use, what each means for you, how the main international insurers approach it, and how to prepare an application that gets you the best terms available.
If you already know your situation and want a shortlist, the Expat Focus comparison tool asks a few questions about you and your move and points you to plans worth a closer look. Compare international health insurance plans
What counts as a pre-existing condition?
Insurers use a broadly similar definition. A pre-existing condition is any illness, injury or symptom for which you have had a diagnosis, treatment, medication, tests or medical advice, or that you have experienced symptoms of, before your policy starts. Most insurers apply this to a look-back period of a set number of years before the start date, and the exact period is written into the policy.
Common examples include asthma, type 1 or type 2 diabetes, high blood pressure, thyroid conditions, a past cancer diagnosis, heart conditions, epilepsy, autoimmune conditions and a history of mental health treatment. Related conditions count too: an insurer treating high blood pressure as pre-existing will usually treat conditions that develop from it in the same way.
Two distinctions matter when you read a policy:
- Chronic conditions are long-term conditions that need ongoing management. Many international plans include a chronic-condition benefit for conditions that develop after you join, which is separate from how they handle conditions you already have.
- Acute onset wording, common in shorter-term and travel policies, covers a sudden flare of a known condition rather than its routine management. It is not the same as cover for the condition itself.
How do international insurers handle pre-existing conditions?
There are three routes. Which ones an insurer offers depends on the insurer, the plan and sometimes where you live.
Full medical underwriting
You complete a medical questionnaire when you apply, declaring your history. The insurer reviews it and tells you before the policy starts exactly how each declared condition is treated. The outcome for a condition is one of: covered as normal, covered with an additional premium (a “loading”), or excluded, with the exclusion written into your certificate. The advantage is certainty from day one. The trade-off is a longer application and a duty to declare everything accurately.
Moratorium underwriting
You do not complete a medical questionnaire. Instead, any condition you have had symptoms of, or treatment or advice for, in the look-back period is automatically excluded for an initial period. If you then go a continuous period without symptoms, treatment, medication or advice for that condition, it can become eligible for cover. The advantage is a fast, simple application. The trade-off is that you only find out whether a particular claim is covered when you make it, so keep good records.
Medical history disregarded and continued personal exclusions
These apply mainly to employer and group schemes. Medical history disregarded means the scheme covers every member’s existing conditions with no underwriting, which is why cover through an employer is often the best route for someone with a significant condition. Continued personal medical exclusions lets you move from one insurer to another and carry over the terms you already had, rather than being underwritten again. Ask about it whenever you switch.
Which international insurers cover pre-existing conditions, and how?
The table summarises each insurer’s published approach for individual expat plans. Terms change and vary by plan and region, so treat this as a guide to what to ask, and confirm the wording on the quote you are offered.
| Insurer | Underwriting offered | How declared conditions are handled | Where to confirm |
|---|---|---|---|
| Cigna Global | Full medical underwriting; transfer terms when moving from another insurer or a group plan; underwriting options guide published | Conditions reviewed case by case: covered, covered with terms, or excluded; undeclared conditions and anything related to them are excluded | Cigna Global underwriting guide and policy wording |
| Bupa Global | Moratorium and full medical underwriting, depending on plan and region | Moratorium: recent conditions excluded for an initial period, then eligible after a continuous symptom-free period; full underwriting: terms confirmed at the start | Bupa Global plan guide for your region |
| Allianz Care | Full medical underwriting on individual plans; moratorium on some plans | Fully underwritten policies cover declared conditions unless the policy documents say otherwise; moratorium conditions become eligible after a continuous symptom-free period | Allianz Care cover queries FAQ and policy documents |
| William Russell | Full medical underwriting; moratorium on some plans for younger applicants; switch terms when moving from another insurer | Under full underwriting, conditions from the look-back period are not covered unless agreed in writing, and the insurer may agree to cover a condition or cover it with an additional premium; under moratorium, recent conditions are excluded until a continuous symptom-free period has passed | William Russell medical underwriting guide and switching guide |
| APRIL International | Declarative medical questionnaire, no doctor’s visit; moratorium wording on some plans | Existing conditions are outside standard cover unless the optional pre-existing condition benefit is added; conditions in the moratorium look-back period are excluded until it passes | APRIL International pre-existing conditions guide |

Will my condition be excluded, loaded or covered?
After underwriting, each declared condition ends up in one of three places, and it helps to know what each means before you accept a quote.
- Covered. The condition is treated like any other. Common for well-controlled conditions with a stable history.
- Covered with a loading. The insurer accepts the condition and charges an additional premium for it. You get certainty that treatment for the condition is covered, at a known cost.
- Excluded. Treatment for the condition, and for anything arising from it, is outside the policy. Everything else is covered as normal. Exclusions are written on your certificate, so read them closely and ask for the wording to be narrowed if it seems broader than your actual history.
Three habits make a real difference:
- Ask for an indication before you apply. Most insurers or brokers will give a view on how a condition is likely to be treated before you commit.
- Declare fully and precisely. Dates, diagnoses, treatments and current medication. An accurate declaration is what protects your claims later: an insurer that finds an undeclared condition at claim time can decline the claim, and in some cases review the policy itself.
- Ask whether an exclusion can be reviewed. Some insurers will reconsider an exclusion after a period without symptoms or treatment. Get the review terms in writing.
What if I’m moving with an employer or joining a group scheme?
Employer-sponsored international plans are often set up on a medical history disregarded basis, so existing conditions are covered from the day you join. If your employer is arranging your cover, ask three things: whether the scheme is medical history disregarded, whether dependants are included on the same basis, and what happens when you leave. Many insurers offer continuation cover so that you can move to an individual plan without fresh underwriting, and that option is worth securing while you are still employed.
Does the destination change the answer?
It can, in three ways.
- Residency and visas. Some countries require proof of private health insurance as a condition of a residence permit, and a few specify minimum cover. Check your destination’s guide on Expat Focus for the current requirement.
- Public healthcare access. As a legal resident you may gain access to the public system, which can sit alongside a private plan for a chronic condition. The balance between the two differs by country.
- Treatment availability. Specialist care, medication availability and prescription rules vary. A plan with a wide network and international medication cover matters more when your condition needs regular specialist input.
The destination guides cover healthcare and insurance requirements country by country.
How to prepare your application
- A medical summary from your current doctor: diagnoses, dates, treatments and outcomes.
- A list of current medication with doses.
- Specialist letters or recent test results for any condition under active management.
- Questions to ask the insurer: the look-back period; whether moratorium or full underwriting is available to you; how chronic-condition benefits work; whether the plan is renewable for life; how exclusions are reviewed; whether medication is covered in your destination.
- If switching insurer, ask about continued personal medical exclusions so you carry your existing terms across.
Frequently asked questions
<strong>Can I get international health insurance with a pre-existing condition?</strong><br>Yes, in almost all cases. The condition may be covered, covered with an additional premium, or excluded, but the rest of your cover is unaffected.
<strong>Do I have to declare a condition that is under control?</strong><br>Yes. Insurers define pre-existing conditions by symptoms, treatment or advice within the look-back period, not by whether the condition is currently causing problems. A well-controlled condition is often covered on good terms, and declaring it is what makes that cover reliable.
<strong>What is a moratorium?</strong><br>An underwriting method with no medical questionnaire. Recent conditions are excluded at the start and can become eligible for cover after a continuous period without symptoms, treatment, medication or advice.
<strong>Can an exclusion be removed later?</strong><br>Sometimes. Some insurers review exclusions after a period without symptoms or treatment. Ask for the review terms in writing when you take out the policy.
<strong>Is travel insurance enough if I’m living abroad?</strong><br>Travel insurance is designed for trips and usually covers only the sudden, acute onset of a known condition rather than its ongoing management. For living abroad, an international health plan is the right tool.
<strong>Does pregnancy count as a pre-existing condition?</strong><br>Insurers treat pregnancy separately, usually through a maternity benefit with its own waiting period. If you are already pregnant when you apply, ask how the plan handles it before you buy.
