About 27347: Open excision of knee cyst
Report open surgical excision of a cyst arising in the knee area, such as a ganglion, when the surgeon removes the cyst rather than aspirating it.
This code describes open removal of a cyst in the knee area, commonly a ganglion cyst. An orthopedic surgeon typically performs the procedure in an operating room, exposing and excising the cyst through an incision. The operative report should establish that the target was a cyst and that it was removed by an open approach, rather than treated by aspiration or arthroscopy.
Select this code for the documented knee cyst; use a code specific to a popliteal cyst when that is the lesion removed. The operative note should identify the cyst’s location and describe the excision. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%; bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
