The "Acute Onset of a Pre-Existing Condition" is a sudden and unexpected outbreak or recurrence of a pre-existing medical condition which occurs without any advance warning either in the form of physician recommendations or symptoms and requires immediate care (within 24 hours of first symptoms).
A Pre-Existing Condition that is a chronic or congenital condition or that gradually becomes worse over time will not be considered acute onset. The acute onset coverage benefit does not include coverage for known, scheduled, required, or expected medical care, drugs or treatment existent or necessary prior to the effective date of coverage. An example of this might be someone who has a food allergy or bee allergy and is unknowingly exposed to their allergen and requires immediate medical attention.
