I sent this email to San Diego Kaiser Permanente's Chief Financial Officer and Chief of Records Lynette Seid today:
Dear Ms. [Lynette] Seid:
Your subordinates have come up completely empty in response to my April 7, 2014 request for radiological images.
I did receive 24 pages of paper records from my medical record today by certified mail.
So it seems that the Radiology Records department is the problem.
