What 17284 covers
billing code 17284 reports destruction of a malignant lesion on the face, ears, eyelids, nose, lips, or mucous membrane when its greatest diameter is 3.1 through 4.0 cm. Destruction may use methods such as electrosurgery, cryosurgery, laser, or chemical treatment. Dermatologists and other qualified clinicians commonly perform the procedure in an office setting, with less frequent facility use. This code describes destruction, rather than excision, of the lesion.
Select the code based on both the anatomic group and the lesion’s diameter. Documentation should identify the malignant diagnosis, precise site, measured diameter, and destruction method. The 10-day minor-procedure global period includes related postoperative visits during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery; co-surgeon and team-surgery reporting are not permitted.
