What 41520 covers
CPT 41520 describes surgical reconstruction of the lingual frenulum, the fold of tissue beneath the tongue. It is commonly used for ankyloglossia when restricted tongue movement calls for frenuloplasty rather than simple division or removal of the frenulum. Otolaryngologists and oral and maxillofacial surgeons may perform the procedure in an office or operating-room setting, depending on the patient and the planned repair.
Select the code when the operative work reconstructs or lengthens the tongue fold; document the functional restriction, relevant anatomy, and repair performed. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
