Acute Onset of Pre-Existing Condition
A sudden, unexpected flare-up of a known condition that some visitor plans cover.
Full Definition
Most visitor insurance plans exclude pre-existing conditions entirely. However, many comprehensive plans include a special benefit for the 'acute onset of a pre-existing condition' — a sudden, unexpected, and life-threatening episode that requires immediate treatment. This coverage has strict limits: it typically excludes chronic management, follow-up care, and known unstable conditions. It is not full pre-existing condition coverage. Age limits and per-incident caps often apply.
Real-World Example
A 68-year-old visitor with known diabetes suddenly collapses from a hypoglycemic emergency requiring an ER visit. Because it was sudden and life-threatening, their comprehensive plan's acute-onset benefit covers the ER bill up to the policy limit, even though diabetes is a pre-existing condition.
