Coding a Colonoscopy
A 61-year-old male patient is being assessed for possible colon cancer and treated in the special procedure unit of the hospital. He undergoes a colonoscopy into the ascending colon with biopsy of a suspicious area in the transverse colon using the cold biopsy forceps. In addition, a colonic ultrasound of the area is performed, with transmural biopsy of an area of the mesentery adjacent to the transverse colon. Assign the appropriate CPT codes.
