Pre-existing conditions are health problems, illnesses, or injuries that a person already has before buying a new health insurance plan. These may have been diagnosed, treated, or shown symptoms in the past, often within the last five years. Even if the condition is under control or has not caused issues recently, it can still count as a pre-existing condition.

Some common examples include:

  • Diabetes
  • High blood pressure
  • Arthritis
  • Glaucoma
  • Heart disease
  • Mental health conditions such as anxiety or depression

When applying for health insurance, it is important to fully disclose these conditions. If not, you may face denied claims or limited coverage later.

Why disclosure matters:

  • Insurers use this information to assess health risks and decide coverage.
  • Some policies may exclude or limit treatment for these conditions.
  • In some countries, regulations stop insurers from refusing cover or charging more, but this may not apply everywhere.

In Thailand, health insurance terms and healthcare costs can differ a lot between providers. Being open about your medical history helps insurers create a suitable plan for you. This way, you get proper coverage and avoid unexpected expenses when you need medical care.

Ignoring pre-existing conditions when living in Thailand can lead to big problems and hidden costs. The main risk is that medical treatments may not be covered by your insurance, leaving you to pay large bills yourself. Healthcare in Thailand can be expensive, and without proper coverage, this can quickly damage your finances.

Many insurers in Thailand may:

  • Exclude coverage for pre-existing conditions
  • Add waiting periods before coverage begins
  • Charge higher premiums to include these conditions

If you don’t disclose your conditions honestly, insurers can reject your claims. This means you might have to pay out-of-pocket for treatments, which is especially costly for chronic illnesses that need regular care and medication.

The risks go beyond money. Long-term visa holders in Thailand must maintain valid health insurance. If your insurance does not meet the requirements, because it excludes your condition or you gave incomplete information, you could face visa problems, fines, or even deportation.

Other risks include:

  • Stress and worry from not having the right cover
  • Delays in getting treatment when you need it
  • Poorer health outcomes due to a lack of proper care

Being open about your medical history and choosing a plan that covers pre-existing conditions helps protect both your health and your legal status in Thailand. It also gives you peace of mind, knowing you are prepared for the unexpected.
