Pre-Existing Conditions What Expats Need to Know

One of the biggest concerns expats face when applying for health insurance in Thailand is how insurers handle pre-existing conditions. Whether it’s diabetes, high blood pressure, or an old injury, knowing your options in advance can save you time, money, and frustration.

What Are Pre-Existing Conditions?

Pre-existing conditions are any illnesses, injuries, or symptoms you had before applying for health insurance. This includes:

• Chronic diseases (e.g., diabetes, hypertension, asthma)
• Past surgeries or hospitalizations
• Ongoing treatments or medications
• Symptoms you experienced but did not formally diagnose

Insurers ask about these conditions in the medical questionnaire during application.

How Insurers in Thailand Handle Pre-Existing Conditions

• Exclusion: The condition is not covered at all.
• Waiting period: Coverage starts only after a defined period (often 1–2 years).
• Premium loading: The insurer covers the condition but charges a higher premium.
• Case-by-case review: Some insurers may cover certain stable conditions with limitations.

Common Challenges for Expats

• Declined applications: Some insurers reject applicants with severe conditions.
• Confusing disclosure rules: Not declaring a condition can lead to claim rejection later.
• Visa requirements: Certain long-term visas require insurance, even if you have pre-existing conditions.
• Changing insurers: Switching providers often means your pre-existing conditions must be reassessed.

Tips for Expats with Pre-Existing Conditions

• Be honest in your application. Non-disclosure can void claims.
• Consider international insurers. They may offer more flexible options than some local providers.
• Look for plans with chronic disease management if you need regular follow-ups.
• Work with a broker who knows which insurers are open to specific conditions.
