Pre-existing Conditions and Global Insurance: What You Need to Disclose 2026

The Most Misunderstood Area of Travel Insurance

Pre-existing conditions are the #1 reason international health insurance claims are denied. Yet most digital nomads don't understand what counts as a pre-existing condition, when they need to disclose it, or what happens if they don't.

Here's the truth: failing to disclose a pre-existing condition can void your entire policy – not just for that condition, but for all claims. Even claims completely unrelated to your disclosed condition can be denied if the insurer discovers you withheld information during application.

                ⚠️ Critical Warning: Insurance companies have access to your medical records through databases like the Medical Information Bureau (MIB). If you lie on an application, they will find out when you file a claim. The result: claim denial, policy cancellation, and potential fraud flags that make future insurance difficult to obtain.
            

What Is a Pre-existing Condition?

Most policies define a pre-existing condition as:

                "Any illness, injury, or medical condition for which you received medical advice, diagnosis, care, or treatment within a specified period (typically 6-24 months) before your policy's effective date."
            

This includes conditions you might not consider "active" – high blood pressure managed with medication, asthma that hasn't flared up in years, mental health conditions, or even past surgeries.

Common Pre-existing Conditions That Require Disclosure:

Asthma or other respiratory conditions
Diabetes (Type 1 or Type 2)
High blood pressure (hypertension)
High cholesterol
Heart disease or past heart attack
Stroke history
Cancer (including past remission)
Thyroid disorders (hypo/hyperthyroidism)
Mental health conditions (depression, anxiety, bipolar, etc.)
Autoimmune diseases (lupus, rheumatoid arthritis, Crohn's, etc.)
Epilepsy or seizure disorders
Chronic pain conditions (fibromyalgia, back pain, etc.)
Past surgeries (even if fully recovered)
Pregnancy (considered pre-existing in some policies)
Allergies requiring prescription medication

How Different Types of Insurance Handle Pre-existing Conditions

Insurance Type	Pre-existing Coverage	Typical Terms
Standard Travel Insurance	Usually Excluded	No coverage for any pre-existing condition. Some offer "waiver" if you buy policy within 14-21 days of first trip payment.
Basic Nomad Plans (SafetyWing, World Nomads)	Excluded	No coverage for pre-existing conditions. Designed for healthy nomads only.
Mid-tier Plans (Genki)	Waiting Period	Stable pre-existing conditions may be covered after 6-12 month waiting period. Must disclose and be approved.
Comprehensive Plans (Cigna Global, AXA)	May Cover	Coverage available with waiting period (6-24 months) or premium surcharge (10-50%). Each condition evaluated individually.
Specialized Pre-existing Plans	Covered (with limits)	Some insurers (GeoBlue, Seven Corners) offer plans specifically for those with pre-existing conditions. Higher premiums, coverage limits apply.

The "Lookback Period" Explained

Every policy has a "lookback period" – the timeframe before your policy start date during which the insurer examines your medical history. Common lookback periods:

Travel insurance: 60-180 days (shorter)
Basic nomad insurance: 6-12 months
Comprehensive international: 12-24 months
Some specialized plans: 3-5 years

If you received treatment, medication, or medical advice for a condition within the lookback period, you must disclose it. If the condition was stable and required no treatment during the lookback period, it may not need disclosure (check your policy's exact wording).

                📌 Example: A policy with a 12-month lookback period. You have asthma but haven't used an inhaler or seen a doctor for it in 3 years. You may not need to disclose it. If you refilled an asthma prescription 8 months ago, you must disclose it.
            

What Happens If You Don't Disclose?

                The Consequences of Non-Disclosure:
                Claim denial: Any claim related to the undisclosed condition will be denied
Policy voidance: Insurer can void your policy from inception (as if you never had coverage)
All claims denied: Even unrelated claims can be denied due to material misrepresentation
Future insurance issues: Your name goes into insurance fraud databases (MIB), making future coverage difficult and expensive
Legal action: In extreme cases, insurers may pursue fraud charges

            

                ✅ The Right Approach: Always disclose everything honestly. If your condition is excluded, you at least know your risk. Some coverage is better than voided coverage. And many conditions can be covered with waiting periods or surcharges.
            

Provider-Specific Pre-existing Condition Policies (2026)

SafetyWing

Policy: No coverage for pre-existing conditions. Period. Do not purchase SafetyWing if you have any ongoing medical condition requiring treatment or medication.

Exception: Acute onset of pre-existing condition (sudden, unexpected flare-up) may be covered for travelers under 65 on some plans – but this is limited and not guaranteed.

World Nomads

Policy: Standard plan excludes pre-existing conditions. "Classic" plan offers limited coverage for stable pre-existing conditions if you complete their medical screening and are approved.

Lookback: 6 months for most conditions.

Genki

Policy: Explorer plan excludes pre-existing conditions at initial purchase. After 12 months of continuous coverage, stable pre-existing conditions may become covered (subject to underwriting).

Best for: Healthy nomads who may develop conditions later, not those with existing conditions.

Cigna Global

Policy: Most comprehensive for pre-existing conditions. Each application is medically underwritten. Stable conditions may be covered after 6-24 month waiting period or with 10-50% premium surcharge.

Best for: Nomads with ongoing conditions willing to pay higher premiums for coverage.

AXA – Global Care

Policy: Similar to Cigna. Medical underwriting required. Waiting periods 12-24 months for most conditions. Premium surcharges for immediate coverage.

Note: AXA is more conservative than Cigna on pre-existing conditions – expect longer waiting periods.

GeoBlue (US citizens)

Policy: Specializes in coverage for Americans abroad. Offers "pre-existing condition coverage" on certain plans with 6-month lookback and coverage after 6-12 month waiting period.

Best for: US citizens with pre-existing conditions who need ACA-style coverage abroad.

How to Disclose Pre-existing Conditions Correctly

Step 1: Gather Your Medical History

Before applying, request your medical records from your primary care physician. You'll need:

List of all diagnosed conditions
Dates of diagnosis
Current medications and dosages
Dates of last treatment or doctor visit
Hospitalizations or surgeries in the past 5 years

Step 2: Complete the Medical Questionnaire Honestly

Don't guess. Don't omit. If a question asks about "any condition in the past 10 years," answer truthfully. If you're unsure whether something counts, disclose it anyway – over-disclosure is not penalized; under-disclosure is.

Step 3: Provide Supporting Documentation

If the insurer requests medical records or a doctor's letter, provide it promptly. Delays can hold up your application for weeks.

Step 4: Get the Decision in Writing

Once approved, request written confirmation of what conditions are covered, excluded, or subject to waiting periods. Keep this document with your policy.

✅ Disclosure Checklist – Ask Your Insurer:

What is your lookback period? (How far back do I need to disclose?)
Which of my disclosed conditions are covered?
Which are excluded?
Are there waiting periods for any conditions?
Can I pay a surcharge to reduce waiting periods?
Will my premiums increase if my condition changes?
Do I need to re-disclose conditions at renewal?

Stable vs. Unstable Conditions

Insurers distinguish between "stable" and "unstable" pre-existing conditions. Stable conditions are more likely to be covered (after waiting periods).

What Makes a Condition "Stable"?

No new symptoms, treatments, or hospitalizations in the past 6-12 months
Medication dosage has not changed
No doctor visits related to the condition (except routine prescription refills)
Condition is considered "controlled" by your physician

What Makes a Condition "Unstable"?

Recent change in medication or dosage
Recent hospitalization or emergency room visit
Ongoing diagnostic testing or treatment plan
Surgery scheduled within the next 12 months
Terminal or progressive conditions (cancer, ALS, etc.)

                💡 Tip: If your condition is unstable, most international insurers will exclude it or deny coverage entirely. Look for guaranteed-issue plans from your home country that offer international coverage (e.g., ACA plans for US citizens with pre-existing conditions).
            

Special Considerations by Condition Type

Mental Health Conditions

Depression, anxiety, bipolar disorder, and other mental health conditions are often excluded from basic travel insurance. Comprehensive plans (Cigna, AXA) may cover them with waiting periods. Some countries require mental health coverage for digital nomad visas – check your destination's requirements.

Pregnancy

Pregnancy is treated as a pre-existing condition by many insurers. Most travel and basic nomad plans exclude maternity coverage entirely. Comprehensive plans cover maternity only after a 10-18 month waiting period. See Episode 8 for full details.

Cancer (Past or Present)

Cancer is the most difficult condition to insure. Most travel and nomad plans exclude any cancer-related claims. Some comprehensive plans may cover after 2-5 years of remission with medical underwriting. Specialized cancer insurance exists but is expensive.

Diabetes

Type 2 diabetes (diet-controlled) may be covered by some comprehensive plans after waiting periods. Type 1 diabetes (insulin-dependent) is often excluded or heavily surcharged. Always disclose diabetes – complications can be catastrophic and expensive.

Comprehensive plans (Cigna Global, AXA) may cover stable conditions after waiting periods (6-24 months) or with premium surcharges
The lookback period determines what you must disclose – typically 6-24 months
Over-disclosure is safe; under-disclosure is fraud – disclose if you're unsure
Get all coverage decisions in writing – know exactly what is covered and excluded
If you have significant pre-existing conditions, consider guaranteed-issue plans from your home country that offer international coverage
