How do insurance companies determine pre-existing conditions?
The common question among elderly travelers is how insurers determine what is considered a pre existing medical condition. No medical examination or doctor’s report is required to purchase short term health insurance. So, how can they know what is pre-existing? The insurance company will rely on information gathered from the care provider, such as, medications taken, onset of symptoms, etc. The general definition of pre-existing condition is: "A condition a person has been diagnosed with, is being treated for, or has with reasonable medical certainty before the start of the plan". So a person does not need to know they have the condition for it to be considered pre-existing (a diagnosis is not required).
