What illnesses are covered under travel insurance?

Editorial team Published on

A covered illness in travel insurance is a sudden, unexpected sickness that meets your specific policy rules and forces you to cancel, interrupt, or seek emergency medical care during a trip.

What Types of Illnesses Are Covered?

  • Sudden sicknesses: Acute conditions like the flu, COVID-19, food poisoning, pneumonia, or norovirus.
  • Emergencies abroad: Serious health issues that require hospitalization, surgery, doctor visits, or prescription drugs while traveling.
  • Before the trip: Sudden illnesses that happen before departure, making you medically unfit to travel (covered under Trip Cancellation Insurance).
  • Family member illness: Severe sickness affecting a non-traveling family member, provided a doctor deems it life-threatening or requiring hospitalization.

What Is Usually NOT Covered?

  • Pre-existing conditions: Chronic or known medical issues active within a specific "look-back period" (usually 60 to 180 days before buying the plan) unless you purchased a pre-existing condition waiver.
  • Minor ailments: Minor symptoms or run-of-the-mill discomforts (like a mild cold or minor stomachache) that do not stop you from traveling or require professional medical care.
  • Normal pregnancy: Routine prenatal care or standard pregnancy, though unforeseen complications (like pre-eclampsia) are often covered.
  • Ignored advice: Traveling against a doctor’s explicit advice or traveling specifically to receive medical treatment.

What illnesses to declare for travel insurance?

You must declare all pre-existing medical conditions and ongoing health issues when buying Foreign travel insurance, even if they are well-managed, mild, or in remission.

Common Illnesses and Conditions to Declare

  • Heart and Circulatory Conditions: High blood pressure (hypertension), high cholesterol, angina, and previous heart attacks.
  • Chronic and Long-Term Illnesses: Diabetes (including pre-diabetes), asthma, chronic obstructive pulmonary disease (COPD), arthritis, epilepsy, Crohn's disease, and gout.
  • Mental Health Conditions: Depression, anxiety, and bipolar disorder.
  • Serious and Past Conditions: Cancer (even if currently in remission), stroke, and transient ischemic attacks (TIAs).
  • Autoimmune Disorders: Lupus, rheumatoid arthritis, and multiple sclerosis.

What Else Counts as a Medical Declaration?

  • Prescribed Medication: Any regular drugs, inhalers, or weight-loss injections you take or were prescribed within the insurer's look-back period (often the last 1 to 5 years).
  • Pending Investigations: Any ongoing tests, scans, specialist referrals, or waiting lists for surgery.
  • Undiagnosed Symptoms: Any active symptoms you have seen a doctor about that do not have a final diagnosis yet.

Failing to declare these details can void your policy and leave you responsible for costly emergency medical bills abroad. Always read the MoneySupermarket Guidance or check with your specific provider if you are unsure.

What pre-existing conditions are not covered by travel insurance?

Standard travel insurance excludes all pre-existing medical conditions by default during a recent "look-back" window unless you purchase a special waiver. Even with a pre-existing condition waiver, many providers and plans—as outlined by Squaremouth—universally exclude specific health issues and situations.

What is a Pre-Existing Condition?

  • Definition: Any injury, illness, or medical symptom that was diagnosed, treated, or had a change in prescription medication during a specific look-back period (usually 60 to 180 days) before you bought your policy.
  • Standard Rule: If your condition flared up, required a new medication, or was unstable during this window, standard insurance will not cover medical costs or trip cancellations related to it.

Conditions Universally Excluded (Even with Waivers)

Most travel insurance policies will never cover claims related to these specific health situations:

  • Mental Health: Conditions like anxiety, depression, and bipolar disorder.
  • Cognitive Disorders: Psychological conditions including Alzheimer’s disease and dementia.
  • Terminal Illnesses: Any condition diagnosed as terminal prior to your trip.
  • Pregnancy: Routine pregnancy care, normal childbirth, or related complications.
  • Substance Abuse: Illnesses or injuries caused by alcohol or drug abuse, or intentional self-harm.
  • Unstable Status: Conditions where your doctor has advised you that you are medically unfit to travel, or if you are traveling against medical advice.
  • Elective Care: Scheduled or elective medical procedures performed during your trip.

How do you prove illness for travel insurance?

To prove an illness for a travel insurance claim, you must submit a signed Attending Physician's Statement or an official medical certificate explicitly stating that you are medically unfit to travel.

Required Medical Documentation

  • Physician Statement Form: An insurer-provided form filled out and signed by your treating doctor.
  • Medical Records: Treatment notes, hospital admission or discharge papers, and diagnostic test results (such as positive COVID-19 reports).
  • Explicit Restriction: A clear written note from the doctor stating your acute illness prevents travel on your specific trip dates. Generic work notes are often rejected.

Supporting Financial and Travel Proof

  • Proof of Cancellation: Written confirmation from airlines, hotels, or tour operators showing the cancellation date and non-refundable amounts.
  • Booking and Payment Records: Your original itinerary, booking confirmation, and receipts showing how you paid for the trip.
  • Proof of Insurance: Your policy confirmation showing coverage active at the time of the incident.

Best Practices for Filing

  • File Promptly: Submit your claim and notify providers within the policy's deadline—usually between 30 to 90 days from the event.
  • Get Evaluated Early: See a doctor on or immediately around the date the illness starts so the medical timeline matches your cancellation date.

What pre-existing conditions need to be declared?

You must declare any past or ongoing health issue, illness, or injury that falls within your insurance provider's medical screening questions when buying insurance.

What You Need to Declare

  • Controlled or stable conditions: Asthma, diabetes, or high blood pressure that is managed well with medication.
  • Past serious illnesses: Cancer (even if in remission), heart attacks, or strokes.
  • Previous surgeries: Joint replacements, heart bypasses, or fitted stents from years ago.
  • Mental health issues: Depression, anxiety, or bipolar disorder.
  • Pending or ongoing investigations: Scans, tests awaiting results, or referrals to a specialist.
  • Undiagnosed symptoms: Any pain or health issue you have seen a doctor for, even without a final name for the condition.

Important Rules

  • Check the timeframe: Most insurers ask about the past 2 to 5 years, but some serious heart or chronic conditions require you to declare them no matter how long ago they happened.
  • Never guess: If you are not sure if a minor or old condition counts, it is always safest to tell the MoneySupermarket or your specific provider. Hiding a condition can make your policy invalid.

What is considered a pre-existing medical condition for travel insurance?

A pre-existing medical condition for travel insurance is any illness, injury, or health symptom that you had, received treatment for, or took medicine for before you bought your policy.

The Look-Back Period

Insurers use a "look-back period" to decide if a condition is pre-existing.

  • Time window: This is a past block of time, usually 60 to 180 days before your policy purchase date.
  • Medical activity: If you saw a doctor, got a new diagnosis, or changed your prescription during this window, the insurer counts it as a pre-existing condition.
  • Undiagnosed symptoms: Even if a doctor has not named the illness yet, clear symptoms that would make a reasonable person seek help can still count.

Common Examples

  • Chronic illnesses: Asthma, diabetes, high blood pressure, and heart disease.
  • Mental health: Depression, anxiety, or bipolar disorder.
  • Recent changes: New injuries, recent surgeries, or adjustments to medicine dosage.

How to Get Coverage

Most standard policies do not cover pre-existing conditions by default. You can remove this exclusion by getting a pre-existing condition waiver.

  • You usually must buy your policy within 14 to 21 days of your first trip payment.
  • You must pay to insure your entire non-refundable trip cost.
  • You can read more about these rules and definitions with Allianz Partners or view tips from Aon.

How far back is a pre-existing condition?

A pre-existing condition look-back period typically ranges from 60 to 180 days for travel insurance or up to 6 to 12 months for standard health applications, though it depends heavily on the type of insurance.

How Look-Back Periods Work by Insurance Type

  • Health Insurance (ACA-Compliant): Under the Affordable Care Act, standard health insurance plans cannot look back at your medical history to deny coverage, drop you, or charge you more for a pre-existing condition. There is no look-back or exclusion period for major medical health plans.
  • Travel Insurance: Most plans use a look-back period of 60 to 180 days right before you buy the policy to see if you received treatment, new medications, or advice for a condition. If your condition was stable and you did not need treatment during that window, it may be covered.
  • Medigap (Medicare Supplement): If you apply outside your initial enrollment window, companies can look back 6 months at your medical history and impose a waiting period of up to 6 months for pre-existing conditions in most states.
  • Disability or Life Insurance: Underwriters may review anywhere from 2 to 5 years (or more) of your medical records to assess your risk profile.

What medical conditions should I avoid flying with?

You should avoid flying with unstable heart or lung conditions, recent major surgeries, active contagious illnesses, or severe trapped-air issues.

Heart and Circulation Problems

  • Recent heart attacks: Postpone flying for several weeks or until your doctor confirms clinical stability.
  • Uncontrolled chest pain: Severe or resting angina makes cabin pressure and lower oxygen levels dangerous.
  • Active blood clots: Deep vein thrombosis (DVT) or recent severe clotting issues increase risk during long flights.

Lung and Breathing Conditions

  • Collapsed lung: A current or recent pneumothorax traps air that expands dangerously at high altitudes.
  • Severe COPD or low blood oxygen: Inability to maintain safe oxygen levels without specialized cabin support.
  • Active pneumonia: Low cabin oxygen and respiratory distress make moderate-to-severe cases unsafe to fly.

Infections and Contagious Diseases

  • Active viral or bacterial infections: Conditions like chickenpox, the flu, measles, or tuberculosis risk spreading disease in a confined cabin.
  • Severe ear or sinus infections: Blocked Eustachian tubes prevent pressure equalization and can cause eardrum rupture.

Surgical and Trapped-Gas Risks

  • Recent surgeries: Avoid flying for at least 10 to 14 days after chest, eye, brain, or abdominal procedures due to gas expansion.
  • Bowel obstruction: Trapped intestinal gas expands by about 30% at cruising altitude.

Pregnancy and Other Issues

  • Late-term pregnancy: Most airlines restrict travel past 36 weeks for single pregnancies (or earlier for multiples/high-risk cases).
  • Uncontrolled seizures: Recent strokes or unstable epilepsy require explicit medical clearance first.
