What 27560 covers
This service treats a patella that has displaced from its normal position while the skin and tissues remain closed. An orthopedic surgeon or other qualified physician may reduce and stabilize the kneecap in an emergency department, office, or hospital setting. The key distinction is that treatment is performed without anesthesia; a tibiofemoral knee dislocation or a patellar fracture is a different injury and calls for a different code selection.
Document the patellar dislocation, the closed treatment performed, and that anesthesia was not used. Choose the anesthesia-requiring sibling when treatment is performed under anesthesia, and the open-treatment code when the surgeon treats the dislocation through an open approach. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
