Different hospitals charge differently for colonoscopy, generally 300 to 400 yuan for ordinary colonoscopy and about 800 yuan for painless colonoscopy. Colonoscopy is mainly divided into general colonoscopy and painless colonoscopy, painless colonoscopy refers to the patient through anesthesia in a deep sleep state, under anesthesia for colonoscopy. Painless colonoscopy needs to be operated with the joint assistance of anesthesiologists and enteroscopists, and cardiac monitoring is required, and the general cost is more expensive, around $800 in most hospitals. However, in general, except for anesthesia and monitoring, the medication and operation of general colonoscopy and painless colonoscopy are the same, and the general cost of each medication and operation is about 400 RMB, so patients can decide which kind of colonoscopy they want to apply according to their own situation.
