Another Reason for Healthcare Reform

My GP has admission privileges to multiple hospitals in the Pittsburgh area.
She retired from one of those hospitals recently. She still retains privileges at several other hospitals and is still practicing.
The hospital [thoughtfully] notified all insurance providers in the area that she had retired.
The insurance companies, in turn, removed from the preferred/approved provider lists.
Because she is no longer on the lists (even though she is still practicing), my insurance will not authorize the CT scans she ordered.

Her office assures me that they are working diligently to have the situation rectified.

Gods forbid this happen to someone with serious medical issues.
