Pre-existing condition: meaning in health insurance

โรคที่เป็นมาก่อนทำประกัน

A pre-existing condition is an illness or injury you had, or had symptoms of, before the policy started; it is usually excluded or covered only under conditions.

Definition

A pre-existing condition is a health problem that existed before the start of your policy: diagnosed, treated, or with symptoms a reasonable person would have consulted for. Insurers assess it from your health declaration.

How insurers treat it

  • Excluded permanently, by a specific exclusion written in your policy
  • Covered after a waiting period (for example after one or two years without symptoms)
  • Accepted with a higher premium (loading)
  • Application declined, for serious conditions

Always declare

Hiding a condition can lead the insurer to refuse a claim or cancel the policy, even for an unrelated problem. When in doubt, declare it and let the insurer decide.

General definition: the exact rules are those of your policy wording.
