In order to assure proper billing, be sure to bring your insurance card and driverâ€™s license onthe day of your procedure. It is important that we have accurate demographic information for your insurance to be processed. We request that any co-pay required by your insurance be paid at the time of registration. Our business office will contact you by phone and/or a letter to discuss the amount that will be due. After your insurance is processed, you will receive a bill from CEC for the facility usage, supplies, medication, etc. You will also receive a bill from yourphysician for the procedure performed. If you have a biopsy or any lab work done, you will receive a bill from the lab where the work was done and from any pathologist involved.
