What is a Pre-Existing Medical Condition?

When a trip cancellation travel insurance company refers to a "Pre-Existing Condition", they are talking about medical conditions that exist in the Lookback Period that immediately preceeds the travel insurance purchase date.

Simply put, a Pre-Existing Condition is any medically documented condition (no matter how minor) an Insured Person, Traveling Companion or Family Member has been treated for, consulted with or received advice on. This includes any adjustments or changes in any prescription drugs or medication during the Lookback Period. The condition has to be medically stable.

Medically Stable also includes the idea that nothing is foreseen or expected to "be a turn for the worse". In other words if you're given a week to live and you want to buy travel insurance for a cruise next month, you can't cover the Pre-Existing Condition. It's like wanting to buy Fire Insurance when your house is on fire.
