Your Results

Simply call Enloe’s Medical Imaging Department, and you will be asked to sign a release of information form. This service is free for patients or $20 for subpoenas.

Insurance & Pre-Authorization

Some exams require pre-authorization. Your doctor’s office should be able to determine if you need pre-authorization, and if so, the doctor’s office can obtain it for you before your exam.

If you need to know whether the procedure is covered by your insurance, you will want to contact your insurance company; your doctor’s office can provide you with the required CPT code for the exam, test or procedure.


You will receive a bill from Enloe for hospital services as well as a bill from a radiologist at Enloe with a “professional fee” for reading of the medical imaging exam. If you have questions about billing, please contact Enloe's Patient Financial Services at 530-332-6300.
