Pre-Existing Conditions and Expat Health Insurance: The Reality Guide

The reality of getting coverage with a pre-existing condition. What to expect, what to disclose, and how to find the best plan.

4 min read

Having a pre-existing medical condition doesn't automatically disqualify you from getting international health insurance. But it does change the conversation significantly. This guide explains what actually happens when you apply with a pre-existing condition, what your options are, and how to find the best coverage for your situation.

What Counts as a Pre-Existing Condition?

The definition varies by insurer, but generally a pre-existing condition is any medical condition, illness, injury, or symptom that existed before your policy start date — whether or not it was formally diagnosed. This includes:

  • Chronic conditions: diabetes, hypertension, asthma, heart disease, arthritis
  • Mental health conditions: depression, anxiety disorders
  • Past surgeries or treatments
  • Conditions you're currently being monitored for
  • Symptoms you've experienced but haven't yet had diagnosed

The Two Underwriting Approaches

Full Medical Underwriting (FMU)

Under FMU, you declare your full medical history when you apply. The insurer reviews it and decides how to handle each condition. Possible outcomes include:

  • Accepted on standard terms: Minor or resolved conditions are often accepted with no exclusion or loading.
  • Specific exclusion: The condition is excluded from coverage. You're covered for everything else, but not for that condition or anything directly related to it.
  • Premium loading: The insurer accepts the condition but charges a higher premium to reflect the additional risk.
  • Postponement: If you're currently undergoing treatment, the insurer may ask you to reapply once treatment is complete.
  • Decline: In rare cases, for very serious conditions, an insurer may decline to cover you at all.

The advantage of FMU is certainty. You know before you need to claim what is and isn't covered.

Moratorium Underwriting

Under moratorium, you don't declare your medical history upfront. Instead, the insurer automatically excludes any condition you've had symptoms, treatment, or medication for in the past 5 years (the exact period varies). After 2 continuous years on the policy without any symptoms, treatment, or medication for a condition, it may become covered.

Moratorium is simpler to apply for, but creates uncertainty. You may not know whether a condition is covered until you try to claim — which is the worst time to find out.

Practical Strategies for People With Pre-Existing Conditions

1. Apply While You're Healthy

The best time to get international health insurance is when you're in good health. If you're considering a move abroad, get insured before any new conditions develop. Conditions that arise while you're already covered are treated as new conditions — not pre-existing.

2. Choose FMU for Clarity

If you have significant pre-existing conditions, Full Medical Underwriting gives you a clear picture of what's covered. Yes, you may get exclusions — but you'll know exactly where you stand. Moratorium might seem attractive (no declarations), but the uncertainty at claim time is worse.

3. Compare Multiple Insurers

Different insurers assess the same condition differently. One insurer might exclude your condition entirely; another might accept it with a premium loading; a third might accept it on standard terms if it's been well-controlled for several years. Getting quotes from multiple insurers is essential if you have pre-existing conditions.

4. Consider Specialist Insurers

Some insurers specialise in covering people with complex medical histories. They may be more expensive, but they offer coverage that mainstream insurers won't.

5. Be Completely Honest

Never omit or misrepresent your medical history on an application. If an insurer discovers you withheld information, they can void your policy — leaving you with no coverage and no refund of premiums. The short-term saving is not worth the risk.

Common Pre-Existing Conditions: What to Expect

ConditionTypical Outcome
Well-controlled hypertensionOften accepted with exclusion or small loading
Type 2 diabetes (well-controlled)Exclusion for diabetes-related conditions, or loading
Asthma (mild)Often accepted with respiratory exclusion
Past cancer (5+ years in remission)Varies widely; some insurers accept, others exclude
Mental health historyOften excluded or subject to waiting periods
Resolved conditions (e.g., broken bone)Often accepted on standard terms

Your Next Step

The only way to know what coverage is available for your specific situation is to get quotes. Different insurers will assess your history differently, and the range of outcomes can be significant.
