Nowadays, virtually all straightforward diagnostic and screening colonoscopies and EGDs are done in physician offices if you are a reasonably healthy person at average risk. If the office you are considering tells you that you need to have it done at the hospital, without a good reason why, you may want to seek a second opinion to be sure. The cost of doing a colonoscopy or EGD in the hospital is much higher. It could be as much as $6000 – $8000 once all the fees are applied and is generally not necessary unless there are specific reasons. If the practice you are considering cannot give you a cash or time-of-service price, look elsewhere to have a colonoscopy. We highly recommend that you go online, and read Google reviews on the facility you are considering. Reviews are usually very honest and can give you a sense of how well patients are treated.
