Otolaryngology surgery
About 69601: Revision mastoidectomy to complete extent
Reports revision of a previously operated mastoid when the surgeon completes the procedure to the extent of a complete mastoidectomy.
An otologist revises a mastoid that has undergone prior surgery and extends the work to a complete mastoidectomy. The operation addresses mastoid disease or anatomy requiring further surgical clearance; it is performed in an operating room, commonly in a hospital facility. The operative report should establish the prior mastoid procedure and describe the extent of the revision and the resulting complete mastoidectomy.
Select this code based on the operative result, not simply because the patient has a history of mastoid surgery. The related preoperative visit on the day before surgery and 90 days of related postoperative care are included in the 90-day global period. 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 multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
