Other extension codes are presented on this slide. Assign code 57 when the tumor is adherent to other structures and pathology is positive for invasion of other organ or it is unknown if there is microscopic involvement. Code 65, #1 on the slide, is assigned for any colon site with invasion of the abdominal wall. Code 66, #2 on the slide, is assigned when there is contiguous tumor spread from the ascending colon to the right kidney. Code 66 is also used when there is extension from the ascending colon to the right ureter or from the descending colon to the left kidney or left ureter. Code 70, #3 on the slide, indicates spread from the cecum, appendix, ascending, descending or sigmoid colon to the fallopian tube, ovary, or uterus. Code 80 indicates other contiguous extension including extension from the transverse colon to the ureter.
