Travel insurance with pre-existing conditions — what to look for and what to declare

Why this matters more than people think

Insurance claim data consistently shows two patterns: travellers with chronic conditions are more likely to claim, and they're more likely to have those claims rejected because of disclosure issues. Both are avoidable with the right policy and the right disclosure.

The cost side: a serious illness or accident abroad can easily reach into 6 figures. Air ambulance repatriation from typical destinations runs £20,000–£60,000+ depending on country and aircraft type. ICU care in the United States can run £10,000+ per day. For UK travellers without adequate insurance, these costs come out of pocket. Travel insurance with pre-existing condition cover is one of the highest-value pre-trip decisions for chronic-condition travellers.

What counts as a pre-existing condition

The definitions vary slightly between insurers but generally include any condition that meets any of:

• You've had symptoms of or been treated for it in the previous 2–5 years (period varies by insurer).
• You're currently taking medication for it.
• You've had tests, investigations, or referrals for it.
• You've had an admission or operation for it.
• You've had specialist follow-up for it.
• You've been told to monitor or manage it.

This means many people have more pre-existing conditions than they realise. Examples that often catch people out:

• High blood pressure being managed with one tablet.
• Asthma you only use an inhaler for occasionally.
• A back problem that flared 18 months ago and has settled.
• Mental health conditions including treated anxiety or depression.
• Investigations for symptoms that didn't result in a diagnosis (e.g. chest pain that turned out to be reflux, after a cardiology referral).
• A planned procedure that hasn't happened yet.
• Pregnancy or recent pregnancy.
• Recent weight loss treatment or bariatric surgery.

When in doubt, declare. The cost of declaring is at most a small premium increase. The cost of not declaring can be the entire claim being voided.

The declaration process

Most insurers have a medical screening process — either an online questionnaire or a phone call with a medical assistance team. Common questions:

• Current medications, doses, and what they're for.
• Any GP or hospital consultations in the previous 2 years.
• Any tests, scans, or investigations in the previous 2 years.
• Any planned procedures or referrals pending.
• Any hospital admissions in the previous 5 years.
• Any chronic conditions diagnosed historically that are still relevant.
• Mental health history.
• Specific conditions: cancer, heart disease, stroke, diabetes, COPD, etc.

Take time over this. Have your repeat prescription list in front of you. Check your GP medical record summary if you're unsure (you can usually access this through the NHS app).

What to look for in a policy

Beyond the basic cover, useful features:

• Medical cover. Minimum £2m Europe, £5m worldwide, £10m United States.
• Emergency dental. Often inadequate in basic policies; check the limit.
• Repatriation. Should be unlimited or very high.
• 24-hour medical emergency assistance. The phone line you call when something goes wrong abroad.
• Pre-existing conditions specifically covered. Listed and confirmed in writing.
• Cancellation cover. Especially important for chronic-condition travellers — covers cost if you can't travel due to flare-up or new diagnosis before departure.
• Curtailment cover. Covers cost if you have to return home early.
• Lost or stolen medication cover. Particularly relevant for chronic-condition travellers — see our prescription medication travel guide.
• Specific activity cover. Skiing, scuba, trekking above certain altitudes, motorcycling, adventure sports — all typically need specific addition.

GHIC vs travel insurance — the difference

The Global Health Insurance Card (GHIC, replacing the older EHIC for UK residents) gives you access to medically necessary state healthcare in EU countries (and some others) on the same basis as residents of that country. Useful but limited:

What GHIC covers:

• Treatment at state-run hospitals and clinics.
• Pre-existing condition treatment.
• Routine maternity care.
• Treatment for chronic conditions while abroad.

What GHIC doesn't cover:

• Private healthcare.
• Repatriation to the UK.
• Most countries outside the EU.
• Lost luggage, cancellation, theft, etc.
• Costs above the state level in countries with charges.
• Any non-EU territories.

The pragmatic position: GHIC is a useful complement to travel insurance for European trips. It is not a replacement. The two work together — if you have an accident in France, the GHIC handles the state hospital admission charges, and your travel insurance handles repatriation if needed.

Condition-specific tips

Diabetes. Declare all forms (type 1, type 2, gestational), all medications (insulin, oral hypoglycaemics, GLP-1s), and any complications. Bring extra insulin/oral medication, sharps disposal plan, glucose monitoring kit, hypoglycaemia treatment. Travel insurance specifically covering diabetes-related care.

Heart conditions. Declare history of MI, angina, arrhythmia, heart failure, valve problems, hypertension, anything cardiac. Carry GTN spray for known angina; recent ECG / specialist letter useful for some destinations.

Respiratory conditions. Asthma, COPD, sleep apnoea, recent chest infections all declarable. Bring spare inhalers, peak flow meter if relevant, written asthma plan.

Mental health. Anxiety, depression, eating disorders, bipolar disorder, psychotic illness — all need declaration. Bring adequate medication supply, contact info for crisis support both in UK and at destination.

Cancer. Past or current cancer, including any treatment in last 5 years, needs declaration. Specific cover may need a specialist insurer. Discuss travel timing with your oncology team.

Pregnancy. Most policies cover pregnancy up to a specific gestation (often 24–28 weeks). Routine antenatal care, complications, and (in some policies) premature birth need specific cover. Discuss travel timing with your midwife.

Post-bariatric surgery and weight loss medication. Recent bariatric surgery is a pre-existing condition. GLP-1 medications (Mounjaro, Wegovy, Saxenda) are usually considered chronic prescriptions — declare. See our post-bariatric Mounjaro guide for related travel considerations.

Recent COVID-19. Some policies have specific COVID-related sections; declare any recent infection requiring medical care.

Older travellers. Premiums climb with age, especially over 65 and 70. Specialist senior-travel insurers often more cost-effective.

If you're refused cover

If standard insurers refuse cover or quote unaffordable premiums:

• Try specialist medical-condition insurers. The MoneyHelper directory lists insurers that specifically cover conditions standard policies won't. Several focus on cancer, heart conditions, mental health, or other specific areas.
• Consider annual multi-trip policies. Often more cost-effective for chronic-condition travellers who take multiple trips a year.
• Don't travel uninsured. The risk is asymmetric — a small saved premium against a potentially life-changing medical bill.
• Get a doctor's report. Some insurers will quote based on a clinical report on stability of your condition; ask your GP or a private clinician.

What to do at the time of a medical incident abroad

1. Contact your insurer's 24-hour emergency line before authorising significant treatment if possible. They direct you to in-network providers and pre-authorise costs.
2. If urgent treatment is needed first, get the treatment then contact insurer as soon as possible.
3. Keep all receipts, medical reports, prescriptions, and diagnostic results.
4. Don't sign cost agreements before checking with insurer if there's time.
5. For repatriation, the insurer arranges and pays directly — don't book your own air ambulance.
6. Notify your GP on return so follow-up is joined up.

How to compare policies

Use comparison sites for the basic shortlist, then read the actual policy wording for the conditions you're declaring. Specific things to check in the policy document:

• Exact pre-existing condition list (medical screening questions).
• Medical cover limit.
• Repatriation cover limit and details.
• Cancellation and curtailment limits.
• Excess (the amount you pay before the insurer pays).
• Specific exclusions (alcohol-related claims, undeclared activities, non-disclosed conditions).
• Activity-specific cover for what you'll actually do.
• Customer reviews of claim experience (not just price).

How this fits with the wider trip

Travel insurance is one component of trip prep. Other relevant guides: travelling with prescription medication, travellers' diarrhoea, malaria tablets compared, Yellow Fever certificate, and the destination-specific guides for India, Bangladesh, Pakistan, and East Africa.

The next step

If you're a chronic-condition traveller and want a structured pre-trip review — medication, insurance discussion, vaccines, destination-specific considerations — a 30-minute travel consultation covers most of it. For insurance specifically, we'll signpost to specialist brokers rather than recommending a specific policy (we're not financial advisers), but we can produce the doctor's letters insurers often need.
