The codes for scope of regional lymph node surgery are shown on this slide. The codes are the same for all sites and are hierarchical. If more than one procedure is performed as part of first course treatment, code the procedure with the highest code. If a patient with adenocarcinoma of the sigmoid colon had a sigmoidectomy and resection of six colic lymph nodes, the lymph node resection would be assigned code 5 for the data item, scope of regional lymph node surgery.
