Multiple Lesions



The doctor removed 3 lesions: 1) left upper back, 2) right upper back, and 3) right lower back. Each lesion was closed in layers. I got the pathology results back and they all were malignant, with clear margins, so I’m ready to code the case. Do I have to use one malignant skin lesion excision code since the lesions are all in the same area (trunk)? Meaning, do I add up the measurements of each lesion and bill one code?


No! Each lesion may be reported separately using a malignant lesion of the trunk CPT code (11600-11606). It is the intermediate repair code that will be the sum (or added up) of the three separate closure lengths (12031-12037).
