What to Do If Your Travel Insurer Rejects Your Pre-Existing Medical Condition Claim

It's entirely normal to visit a GP for a minor ache or a routine check-up before heading off on holiday. But most policyholders don't realise that if they later need medical treatment abroad, their travel insurer might comb through those exact GP notes to find a reason to refuse the claim.

When an insurer turns down a claim by pointing to a pre-existing medical condition, it can feel like a final decision. The reality is that insurers often stretch the definition of a medical condition far beyond what UK consumer rules actually permit.

What Qualifies as a Pre-Existing Medical Condition?

When you submit a claim for emergency medical treatment abroad, your insurer will usually ask for your medical history. Insurers often widen the definition of a pre-existing medical condition to catch symptoms that were present before the policy started, even if you never had a formal diagnosis.

Under UK consumer rules, that approach is often incorrect. To count as pre-existing, you must have had treatment, advice or counselling for the actual condition being claimed for. In other words, what you knew at the time you bought the policy matters more than what later appears in your medical notes.

Pre-existing medical condition exclusions are what the law calls a significant limitation. If a term significantly limits a main benefit of the policy, whoever sold you the policy had to draw it to your attention at the point of sale. They usually do this in a policy summary. If they didn't draw it to your attention, the insurer isn't allowed to rely on the exclusion to refuse your claim.

How Far Back Are Insurance Companies Willing to Go?

Travel insurance policies usually include a look-back period. This is a set window of time before you buy the policy, typically 60 to 180 days, where your insurer expects your health to have been stable. If you had a change in medication, a new diagnosis, or a hospital stay within that specific window, they expect you to declare it.

But a look-back period only applies to the specific questions the insurer asks. If they ask about hospital stays in the last twelve months, you don't have to tell them about a surgery from three years ago.

You also need to look at how the policy treats an acute onset or an unexpected flare-up. If a condition was completely stable and required no changes to routine care during the look-back period, a sudden and unexpected flare-up while on holiday might still be covered, depending on the exact policy wording.

Should You Declare Pre-Existing Conditions on Travel Insurance?

The short answer is yes, but only if the insurer asks you about them. Under the Consumer Insurance (Disclosure and Representations) Act 2012, an insurer cannot expect you to volunteer information. If they want to know something, they have to ask a clear question about it.

Your answers also need only be true to the best of your knowledge. An innocent mistake is not enough for an insurer to refuse your claim. If you believed your answer was true when you bought the policy, the insurer cannot refuse your claim on the basis that it turned out to be factually wrong.

All travel policies require you to take reasonable care when answering these questions. To refuse a claim on this ground, your insurer must show that you realised there was a risk your claim might happen, and that you either took no steps at all to prevent it or only took steps you knew would be inadequate.

Recurring Insurer Excuses and How to Address Them

Insurers often treat any incorrect answer as a deliberate attempt to hide a medical history. They use this to avoid the policy entirely, meaning they treat it as if it never existed, and they refuse the claim. But the law makes a strict distinction between a deliberate lie and a careless mistake.

Where you knew a fact but failed to disclose it through a one-off careless mistake, that mistake can be treated as excusable. The insurer then cannot simply avoid the policy and should rewrite it on the terms and at the premium they would have charged had they known of the true position, and respond to the claim proportionately.

This happens frequently with minor injuries. Take a knee or ankle previously seen by a GP, then injured on the slopes. If you forgot to mention the earlier GP visit because it seemed trivial at the time, this can be considered as careless (and not deliberate) misrepresentation.

The insurer must show that your misstatement was a real and substantial reason why they entered into the insurance on the terms and at the price they did. If they would have insured you anyway, perhaps for a slightly higher premium, then they should pay a proportionate part of the claim.

Steps to Take Before You Reply to a Refusal

Before you write back to challenge the decision, you need to gather the facts the insurer is relying on. Submitting a rebuttal letter acts as a formal complaint, so the insurer must handle it fairly under FCA claims-handling rules. Take these specific steps below to build your case:

1. Ask for the reason in writing. If your insurer told you over the phone that your claim is refused, ask them to explain their reason in a formal letter. You need to see exactly which policy clause they are leaning on.

2. Check your policy summary. Look at the documents you received when you bought the policy. Check if the medical exclusion they are using was clearly drawn to your attention as a significant limitation.

3. Request your statement of facts. This is the record of what you told the insurer at purchase. Ask your insurer for it so you can review the exact questions you were asked, and confirm you only answered what was asked.

4. Review your GP notes. Look at your medical history for the period before you bought the policy. Check if you actually received treatment, advice, or counselling for the specific condition, or if you merely experienced undiagnosed symptoms.

How SmarterClaims Can Help

If your travel insurance claim has been refused for a pre-existing medical condition, you don't have to just accept the insurer's decision. SmarterClaims can help you review the insurer's refusal letter and your policy documents to identify the correct consumer protection arguments.

The tool can help you apply the reasonable care standard from the Consumer Insurance (Disclosure and Representations) Act 2012 to your specific situation. It then drafts a plain-English rebuttal letter that you can send yourself to challenge the insurer's reasoning.

SmarterClaims is built on the 40-year playbook of Steve Smart, former UK General Counsel at AIG and current Chairman of Lancashire Insurance UK. More than £25M has been recovered in refused claims with Steve's playbook. The platform uses that expertise to give you a clearer basis on which to ask the insurer to reconsider its position.

Final Thoughts

An innocent mistake or a previously undiagnosed symptom does not give an insurer the automatic right to refuse your travel insurance claim under UK consumer rules. An unchallenged refusal usually stands, especially when it cites a medical exclusion.

Understanding what the insurer actually has to prove is the key to pushing back. They have to show that you were asked a clear question, that you were reckless in answering it, and that the exclusion they are relying on was drawn to your attention when you bought the policy.

Knowing these rules allows you to put forward your position clearly and seek a fair outcome. If the insurer still refuses to apply the correct legal test, you can then take your complaint to the Financial Ombudsman Service for an independent review.
