Open Access Colonoscopy Program

Yi Zheng MD Gastroenterology offers the Open Access Colonoscopy Program. The program is designed to allow healthy patients without significant gastrointestinal symptoms to have a colonoscopy without the inconvenience of a preliminary office visit. This is an easier, faster process designed for patients who have few ongoing medical problems and who are not taking many medications. If you have recently had a thorough physical examination by your physician and you need a first-time screening colonoscopy, we can often streamline the process for you by getting you in for this procedure very quickly without the extra time and expense spent for an office visit.
