Flexible Sigmoidoscopy, Diagnostic

Colorado rates for HCPCS 45330

In this exam, a thin, flexible, lighted scope is passed through the rectum into the lower part of the colon to look for polyps, inflammation, bleeding, or other abnormalities. It examines only the lower portion of the colon rather than the entire length, which a full colonoscopy would cover. This version is diagnostic, meaning it is a look-and-report exam without a biopsy or other treatment performed during the same visit.
