In simple words: The doctor examines your colon using a thin, flexible tube with a camera and light (colonoscopy).They also use ultrasound through the tube to get detailed pictures, helping them diagnose problems like colon cancer.

This CPT code describes a flexible colonoscopy with endoscopic ultrasound (EUS) examination. The EUS examination is limited to the rectum, sigmoid colon, descending colon, transverse colon, ascending colon, cecum, and adjacent structures.The procedure involves inserting a colonoscope through the anus and advancing it to the cecum. The provider inspects the colon and rectum, and then introduces an ultrasound probe through the scope to perform the EUS examination. This helps in diagnosing and staging colon cancer.

Example 1: A 60-year-old patient presents with symptoms suggestive of colon cancer. A flexible colonoscopy with EUS is performed to visualize the colon and obtain tissue samples for biopsy, allowing for accurate diagnosis and staging of the cancer., A 55-year-old patient undergoes a screening colonoscopy. During the procedure, a suspicious polyp is identified. EUS is used to determine the depth of invasion and assess the need for further interventions such as surgical resection., A 70-year-old patient with a history of colon cancer undergoes a follow-up colonoscopy.EUS is used to evaluate for recurrence and to guide any necessary therapeutic interventions such as ablation or stent placement.

* Pre-procedure patient history and physical examination findings.* Indication for the procedure (e.g., screening, diagnostic, therapeutic).* Detailed description of the endoscopic findings.* Results of the endoscopic ultrasound examination, including images and measurements.* Number and location of biopsies performed.* Any complications encountered during the procedure.* Post-procedure care instructions.

** This procedure may be performed with or without biopsy or other therapeutic interventions.Appropriate documentation must reflect the specific services performed.
