Question: How do we code for CO2 laser ablation of carcinoma in situ of the face? Would it be appropriate to use a dermabrasion code such as 15781 if the operative note is dictated as “C02 laser ablation of carcinoma in situ of the face (not full face-segmental)?”
Answer: Report the procedure with the appropriate destruction code from the 17000-17250 (Destruction [e.g., laser surgery, electrosurgery, cryosurgery, chemosurgery, surgical curettement], premalignant lesions [e.g., actinic keratoses] …) series, depending upon the exact symptom(s).
Remember: Coding for dermabrasion is based on the location and the size of the area treated. A powered rotary instrument is used to “sand down” or smooth scarred or wrinkled areas. This procedure lowers raised lesions or thins tissue to regenerate skin with a smoother appearance.
Use code 15780 (Dermabrasion; total face [e.g., for acne scarring, fine wrinkling, rhytids, general keratosis]) for the total face, 15781 (... segmental, face) for a segment of the face, and 15782 (... regional, other than face) for regional dermabrasion of an area other than the face. Report 15783 (... superficial, any site [e.g., tattoo removal]) for a superficial site, such as a tattoo.
