What 21047 covers
This service removes a benign cyst or tumor arising in the mandible when removal requires an osteotomy performed through the mouth, extraction of a tooth, or both. The surgeon also repairs the operative site. Oral and maxillofacial surgeons commonly perform the procedure in an ambulatory surgery center or hospital; selected cases may be performed in an office setting. The operative report should identify the mandibular lesion and document the intraoral approach, bone work, any tooth extraction, and repair.
Report this code when the required intraoral osteotomy or tooth extraction distinguishes the operation from simpler enucleation and curettage. The repair associated with the excision is part of the service. Medicare includes the day-before preoperative visit and 90 days of related postoperative care in its 90-day global period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this service.
