What it is
A flexible sigmoidoscopy uses a thin camera to look at the rectum and the lower part of the colon, not the whole colon. It is used to check symptoms like bleeding or changes in bowel habits, and sometimes for screening.
What the price covers
The listed price usually covers the procedure. The doctor's fee may be billed separately, and a biopsy or polyp removal changes the code and adds pathology.
