Why Was My Travel Insurance Medical Claim Rejected? A UK Guide

Having a travel insurance medical claim rejected can be frustrating, particularly when you genuinely became ill or needed medical treatment while travelling.

However, a rejected claim does not necessarily mean that you had no valid reason to claim.

Travel insurance claims can be declined for several reasons. A pre-existing medical condition, missing health information, a policy exclusion, insufficient medical evidence or failure to follow the insurer’s claims procedure can all affect the outcome.

The first step is to find out why the insurer rejected your claim. Once you know the reason, you can compare the decision with your policy wording and check whether the medical evidence and circumstances have been considered correctly.

Why do travel insurance medical claims get rejected?

There is no single reason why a medical travel insurance claim may be declined. Each claim is assessed against the relevant policy, the circumstances surrounding the illness or injury and the evidence available.

Common reasons include:

• the illness or injury is linked to a pre-existing medical condition
• a medical condition was not disclosed when the policy was purchased
• your health changed after taking out the policy and the insurer was not informed
• the treatment is excluded under the policy
• the insurer considers the treatment medically unnecessary
• there is insufficient medical evidence
• the required claims procedure was not followed
• medical reports, receipts or other supporting documents are missing
• the circumstances do not meet the policy definition of a covered event
• a specific exclusion applies to the treatment or circumstances.

Even when you received genuine medical treatment, that does not automatically mean every associated expense is covered.

For that reason, the rejection should be assessed against the actual wording of your policy, rather than the general assumption that travel insurance covers every medical expense incurred abroad.

1. The insurer says your condition was pre-existing

One of the most common issues with medical travel insurance claims is a connection between the claim and a condition that existed before the policy began.

A pre-existing medical condition can include an illness, injury or health problem that existed before you purchased or renewed your insurance. The exact definition, however, depends on the insurer and the terms of your policy.

Consider a traveller with a history of asthma who develops serious breathing difficulties abroad. The insurer may investigate whether the treatment was connected to the existing condition.

That does not automatically mean the claim should be rejected.

Instead, the insurer may need to consider questions such as:

• What medical conditions existed before the policy was purchased?
• What did the insurer ask you to declare?
• What information did you provide?
• Was the condition accepted for cover?
• Did you pay an additional premium for medical cover?
• Is the illness actually connected to the previous condition?
• What does the policy say about pre-existing conditions?

Consequently, the medical history alone may not tell the whole story.

The Financial Ombudsman Service deals with disputes involving pre-existing medical conditions and may consider the policy wording, medical evidence and information provided when the insurance was purchased.

2. You did not disclose a medical condition

Another possible reason for rejection is that the insurer believes you did not provide relevant health information when purchasing the policy.

Travel insurance applications can ask about matters such as:

• diagnosed medical conditions
• recent consultations
• medication
• ongoing treatment
• planned investigations
• hospital treatment
• previous serious illnesses
• changes in health.

If you were specifically asked about a condition and did not disclose it, the insurer may investigate whether that information affected the cover available to you.

However, the situation is not always as simple as saying, “You did not disclose it, therefore the claim is invalid.”

The insurer may need to consider what questions were actually asked, what information you provided and the circumstances surrounding the omission.

If you are unsure why your claim was declined, ask the insurer to explain:

• which information it believes was missing
• which question or part of the application is relevant
• which policy term it is relying on
• how the alleged non-disclosure affected your claim.

That explanation gives you something specific to review instead of trying to guess why the claim failed.

3. Your health changed after buying the policy

Your circumstances can also change after the insurance has been purchased.

Some travel insurance policies require you to tell the insurer about significant changes in your health before travelling or within a specified period.

For example, you might:

• receive a new diagnosis
• start a new course of treatment
• develop new symptoms
• be referred for further investigations
• be placed on a waiting list
• experience a significant deterioration in an existing condition.

Whether you were required to notify the insurer depends on the policy and the circumstances.

Therefore, buying travel insurance once does not necessarily mean that every subsequent change in your health is automatically covered.

If your health changed after purchasing the policy, check the relevant policy conditions and contact the insurer if you are unsure what you were required to report.

4. There is not enough medical evidence

Sometimes the problem is not that the illness did not happen.

Instead, the insurer may believe there is not enough evidence to establish that the claim falls within the policy.

Medical evidence can be particularly important when the insurer needs to establish:

• what condition you had
• when your symptoms began
• what treatment you received
• whether the treatment was medically necessary
• whether the condition was pre-existing
• whether the illness was connected to an earlier condition
• whether you were medically unable to travel
• whether hospitalisation was necessary
• whether cancellation or curtailment was medically justified.

Depending on the circumstances, useful evidence could include medical records, hospital documentation, treatment records, prescriptions, invoices, medical reports or other relevant documents.

A doctor’s letter or medical certificate can sometimes help clarify the circumstances. However, the document should contain accurate information relevant to the actual medical situation.

In other words, medical documentation can support a genuine claim, but it cannot guarantee that the insurer will accept it.

If the insurer says the evidence is insufficient, ask exactly what information is missing before requesting additional documentation.

5. The insurer says the treatment was not medically necessary

A medical claim can also be disputed if the insurer believes that treatment received abroad was not medically necessary or does not fall within the policy’s definition of covered treatment.

For example, the insurer may question:

• why treatment was required
• whether the treatment could reasonably have waited
• whether it was connected to an excluded condition
• whether it was routine rather than emergency treatment
• whether the treatment falls within the medical cover provided.

That does not mean you should avoid seeking medical attention when you are genuinely unwell.

Your health should come first.

Where it is practical and safe to do so, contact your insurer or its medical assistance service as soon as possible and follow the instructions provided.

If the situation is an emergency and contacting the insurer beforehand is not reasonably possible, obtain appropriate medical care first and make contact as soon as you can afterwards.

6. You did not follow the insurer’s claims procedure

Travel insurers commonly set out specific procedures for making or managing a claim.

For example, your policy may require you to:

• contact the assistance service
• obtain authorisation for certain treatment
• notify the insurer as soon as possible
• provide medical documentation
• retain receipts
• submit invoices
• complete a claim form
• obtain information from the treating medical provider.

Following these requirements can be important because the insurer may need certain information before it can assess the claim.

However, a failure to follow a procedure does not automatically answer the question of whether a rejection is fair.

The circumstances matter.

For instance, someone experiencing a medical emergency may not have been in a position to call their insurer before receiving treatment. In that situation, explain what happened and provide evidence showing why prior contact was not reasonably possible.

7. The treatment is excluded from your policy

Travel insurance does not cover every medical situation.

Depending on the policy, exclusions can relate to:

• pre-existing medical conditions
• alcohol or drug-related incidents
• certain sports or activities
• travelling against medical advice
• treatment considered unnecessary
• planned medical treatment
• specific procedures or circumstances
• destinations or activities excluded by the policy.

The exact exclusions vary between insurers.

As a result, looking only at the headline amount of medical cover can give you an incomplete picture.

A policy might advertise a high level of medical cover while still excluding particular circumstances that are relevant to your claim.

Before challenging the rejection, identify the exact exclusion the insurer has relied upon.

Then read the wording carefully and compare it with what actually happened.

8. The insurer says your claim does not match the medical circumstances

Another possibility is that the insurer accepts that you were ill but disputes whether the illness caused the particular financial loss you are claiming.

There is an important difference between:

“I became unwell while abroad.”

and:

“My illness resulted in a loss covered by my travel insurance policy.”

The first statement describes a medical event.

The second requires the insurer to establish whether that event meets the policy’s definition of an insured loss.

For example, a medical expenses claim may depend on whether the treatment is covered.

A cancellation claim may require the illness to meet the policy’s requirements for cancelling the trip.

Similarly, a curtailment claim may require evidence that the medical circumstances justified ending the journey early.

Therefore, the medical event and the insured financial loss need to be considered separately.

What should you do if your travel insurance medical claim is rejected?

Do not immediately assume that the insurer’s decision is the end of the matter.

Start with the written rejection or decision from the insurer.

You want to establish:

• Why was the claim rejected?
• Which part of the policy does the insurer rely on?
• What medical evidence was considered?
• Does the insurer believe the condition was pre-existing?
• Does it believe relevant information was not disclosed?
• Is the problem missing evidence rather than a lack of cover?
• Can additional information or documentation address the issue?

Once you have those answers, compare the decision with your policy wording.

Importantly, do not look only at the summary page or marketing information. Check the relevant definitions, exclusions, medical conditions section, claims conditions and any special terms attached to your policy.

That is where the actual basis of the insurer’s decision is likely to become clearer.

Can additional medical evidence help after a claim is rejected?

Sometimes it can.

If the insurer says that there is insufficient evidence, additional medical documentation may help clarify what happened.

Depending on the claim, this could include:

• a doctor’s letter
• medical certificate
• GP records
• hospital records
• consultant reports
• treatment records
• prescription information
• medical invoices
• discharge documentation.

The purpose of this evidence should be to establish the facts of the medical situation.

It should not be used to create an explanation that is unsupported by your medical records.

For example, if the insurer needs confirmation that you were medically unable to travel, simply obtaining a general note confirming that you attended a doctor’s appointment may not answer the question.

Instead, ask the insurer what specific information it needs.

That can help you obtain relevant documentation rather than collecting paperwork that does not address the reason for rejection.

What if the insurer says your medical evidence is not recent enough?

A rejection based on the age of medical evidence should be considered in context.

There is no universal rule saying that every doctor’s letter becomes invalid after a particular number of days.

Instead, the usefulness of a document depends on what it is being used to establish.

For example, an older medical record may help demonstrate your medical history. Recent evidence, on the other hand, may be more relevant when establishing a new illness, deterioration or current inability to travel.

If the insurer says your evidence is too old, ask:

• What information is missing?
• What date range is required?
• Is an updated doctor’s letter needed?
• Would medical records be sufficient?
• Is the problem the age of the document or the information contained in it?

This approach can prevent you from paying for unnecessary documentation.

Can you appeal a rejected travel insurance medical claim?

If you believe the insurer’s decision is incorrect or unfair, you can normally challenge it through the insurer’s complaints process.

Your complaint will be stronger if it responds directly to the reason given for the rejection.

For example, you might explain that:

• the medical condition was disclosed when you purchased the policy
• the insurer accepted the condition for cover
• the medical evidence does not support the insurer’s interpretation
• the treatment was medically necessary
• an emergency prevented you from contacting the insurer beforehand
• the cited exclusion does not apply to your circumstances
• additional evidence clarifies the medical circumstances.

Keep the explanation factual and attach relevant supporting documents.

Avoid exaggerating what happened. Insurance decisions are based on evidence, so inaccurate information can create additional problems.

What if the insurer still refuses to pay?

If you have complained to the insurer and remain unhappy with its final response, you may be able to take the complaint to the Financial Ombudsman Service.

The Ombudsman can consider eligible complaints about travel insurance. In doing so, it may look at the policy terms, the circumstances of the claim and the evidence provided by both sides.

You should normally give the insurer an opportunity to resolve the complaint first.

During the process, keep copies of:

• your policy documents
• the rejection letter
• your complaint
• the insurer’s response
• medical evidence
• receipts and invoices
• relevant correspondence
• a timeline of events.

Having a clear record can make it much easier to explain why you believe the decision should be reconsidered.

What medical evidence should you keep for a travel insurance claim?

The most useful evidence depends on the type of claim.

If you receive medical treatment abroad, keep:

• medical reports
• hospital paperwork
• prescriptions
• invoices
• receipts
• discharge documentation
• details of the treating provider
• dates of treatment
• correspondence with the insurer.

A claim involving cancellation or being medically unable to travel may require different evidence. In those circumstances, medical documentation may need to explain your condition and how it affected your ability to travel.

The goal is not to collect as many documents as possible.

Instead, the evidence should be relevant, accurate and capable of supporting the circumstances described in your claim.

A rejected claim does not always mean the claim was invalid

A travel insurance medical claim can be rejected for a legitimate policy reason.

At the same time, a rejection can sometimes be challenged if the insurer has misunderstood the medical evidence, applied an exclusion incorrectly, overlooked relevant information or reached a decision that does not properly reflect the policy and circumstances.

A useful way to approach the situation is:

Rejection reason → policy wording → medical evidence → missing information → complaint or appeal

This gives you a structured way to work through the decision.

Rather than simply arguing that you were genuinely ill, focus on why the illness should be covered under the specific terms of your policy.

Need medical documentation for a genuine travel insurance claim?

If your insurer has requested medical documentation, first establish what the document needs to demonstrate.

A doctor’s letter or medical certificate may help provide evidence about your condition, treatment or ability to travel, depending on the circumstances and the insurer’s requirements.

The information should always accurately reflect your genuine medical circumstances.

It should never be altered, exaggerated or created to support a claim that is not medically justified.

If you need legitimate medical documentation for a genuine insurance claim, you can explore the relevant Doctor’s Note / Medical Documentation service from DoctorsNotes.co.uk.

A medical document can provide supporting evidence for a legitimate claim. It cannot, however, guarantee that an insurer will approve the claim or pay the amount requested.

Frequently Asked Questions

Why would a travel insurance medical claim be rejected?

Common reasons include a pre-existing medical condition, non-disclosure of relevant health information, a policy exclusion, insufficient medical evidence, failure to follow the claims procedure or treatment that does not meet the policy’s definition of a covered expense.

Can a travel insurance claim be rejected because of a pre-existing condition?

Yes, depending on the policy and circumstances.

However, the situation should be considered in context. If the condition was disclosed and accepted for cover, or the insurer’s interpretation of the medical evidence is disputed, you may have grounds to challenge the decision.

Can I appeal a rejected travel insurance medical claim?

You can normally ask the insurer to review the decision through its complaints process.

If the insurer does not resolve the complaint and you remain unhappy, you may be able to take the matter to the Financial Ombudsman Service, subject to its eligibility and applicable time limits.

Can a doctor’s letter help with a rejected travel insurance claim?

It can help when the insurer needs relevant medical evidence addressing the reason for rejection.

However, the letter should contain accurate information based on your genuine medical circumstances. A doctor’s letter does not guarantee that a claim will be accepted.

What if I could not contact my insurer before getting medical treatment abroad?

An emergency may make it impossible to contact the insurer beforehand.

In that situation, obtain appropriate medical care first and contact the insurer as soon as reasonably possible. Keep your medical records, receipts and other evidence relating to the treatment.

Can an insurer reject my claim because I did not declare a medical condition?

It may do so if the condition was relevant to the questions asked when the policy was purchased and the circumstances meet the applicable policy and insurance requirements.

If you believe the insurer has misunderstood what you disclosed, check your original application and ask the insurer to explain the basis of its decision.

How long does a travel insurance claim appeal take?

There is no single timeframe for every claim.

The process can depend on the insurer, the complexity of the circumstances and whether additional medical evidence is required. Check the insurer’s complaints procedure and any relevant deadlines.

Should I get a new doctor’s letter after my claim is rejected?

Not automatically.

First, find out why the claim was rejected and what evidence the insurer says is missing. A new document may be useful if it provides relevant information, but obtaining additional paperwork without understanding the problem may not resolve the dispute.

Conclusion

A rejected travel insurance medical claim does not always have a straightforward explanation.

The most important step is to identify exactly why the insurer rejected the claim. From there, compare that reason with the policy wording and the medical evidence available.

If the issue involves a pre-existing condition, check what you disclosed and whether the condition was covered.

Where the problem concerns medical evidence, ask the insurer precisely what information it believes is missing.

If an exclusion has been applied, read the wording carefully and consider whether it actually applies to your circumstances.

Finally, if you believe the decision is wrong, use the insurer’s formal complaints process rather than simply abandoning the claim.

Above all, medical documentation should accurately describe your genuine medical circumstances. It can provide valuable evidence for a legitimate insurance claim, but no doctor’s letter or medical certificate can guarantee a successful outcome.
