What 41153 covers
This operation removes diseased tissue from the floor of the mouth and includes a radical neck dissection in the same surgical service. It is commonly performed by an otolaryngologist or head and neck surgeon for a malignancy involving the floor of the mouth with cervical nodal disease or risk requiring neck surgery. The procedure is generally performed in a hospital operating room.
Select this code when the operative report supports floor-of-mouth resection and the included radical neck dissection; it is not the code for a floor-of-mouth resection without neck dissection or for a primary tongue resection. The note should identify the operative site, extent of resection, and neck procedure. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. For other procedures performed in the same session, the highest-valued procedure is paid in full and additional procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be allowed; co-surgeons require supporting documentation, and team surgery is not permitted.
