Surgical Procedure Primary Site: Colon, Rectosigmoid, Rectum
Code 00: None
Codes 10–14: Local tumor destruction without pathology specimen
Codes 20–29: Local tumor destruction with pathology specimen
For colon, rectosigmoid, and rectum, use code 00 when no surgery of the primary site was performed. Codes 10–14 are assigned when the procedure provides local tumor destruction but there is no pathology specimen. These include photodynamic therapy, electrocautery, cryosurgery, and laser ablation. Photodynamic therapy uses light to destroy the tumor; electrocautery burns the tumor; cryosurgery destroys the tumor by freezing it; and laser destroys tumor with an intensely powerful beam of light. Use codes 20–29 when the procedure locally destroys the tumor and there is a pathology specimen. This includes excisional biopsy and polypectomy.
