Please check your insurance provider to determine the procedures you need to follow in order to have your gastroenterology treatment covered. For example, you may need a referral from a primary care physician to be treated by a specialist. If you do, please obtain the referral prior to your visit and bring the referral with you. You may not be covered for your treatment if you do not follow the procedures required by your insurance carrier. This may result in being responsible for the cost of your treatment.

The endoscope allows the doctor to look for ulcers, inflammation, tumors, infection or bleeding. Tissue samples can be obtained, and bleeding can be treated through the endoscope. We perform Endoscopy procedures in our office or in the hospital.
