What 23491 covers
This service stabilizes a scapula at risk of fracturing before a fracture occurs. The surgeon reinforces the bone with fixation such as a plate, pins, or wires, with or without bone cement. A typical setting is a hospital operating room, and the procedure may be performed by an orthopedic surgeon, including an orthopedic oncologist, when a lesion has substantially weakened the scapula. The operative note should identify the scapular site, the structural concern and fracture risk, and the stabilization performed.
Report the service for preventive reinforcement, not simply because a scapular lesion is present or because an established fracture is being repaired. Document the indication, laterality, fixation method, and any cement use. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and the 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.

23491 billing questions
When is this code appropriate instead of 23490?
Use this code for prophylactic stabilization of the scapula. Code 23490 describes the analogous preventive stabilization of the clavicle.
Is this for a scapular fracture that has already occurred?
It describes preventive reinforcement when the scapula is at risk of fracture. A procedure treating an existing fracture requires the applicable fracture-treatment code instead.
Can removal of the bone lesion also be reported?
A separately performed lesion excision or curettage may be reportable with stabilization. Document each distinct service and check applicable coding edits.
What documentation supports prophylactic stabilization?
Document the scapular site, the lesion or other structural weakness, why fracture risk warrants preventive surgery, and the fixation performed, including laterality and cement use when applicable.
How are bilateral procedures and other same-session procedures paid?
CMS pays bilateral reporting with modifier 50 at 150%. In a same-session multiple-procedure situation, the highest-valued procedure is paid in full and other procedures at 50%.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
