What 23146 covers
An orthopedic surgeon removes or curettes a benign bone cyst or tumor in the scapula and fills the resulting bone defect with allograft. The service is performed in an operative setting when the lesion requires surgical treatment; it is distinct from removing a lesion in the clavicle or humerus. The allograft is the differentiating feature of this scapular lesion procedure.
Select the code when the operative report supports the scapular site, removal or curettage of a benign lesion, and placement of allograft. The 90-day global period includes the day-before preoperative visit and related postoperative care during the following 90 days. If multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others 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.

23146 billing questions
When should this code be selected instead of 23145?
Use 23146 for a scapular lesion procedure that uses allograft. Code 23145 represents a different graft approach for a scapular lesion.
Does the code cover removal of a humeral lesion?
No. This code is for a lesion in the scapula; humeral lesion procedures are reported from the humerus code series, such as 23150 or 23155.
What documentation supports reporting this code?
The operative report should identify the scapular lesion, describe its removal or curettage, and document use of allograft to fill the bone defect.
How is bilateral reporting handled?
For a bilateral procedure, report modifier 50; CMS pays the bilateral procedure at 150%.
Can an assistant surgeon be reported?
Assistant-at-surgery payment is allowed only when the record documents medical necessity. Co-surgeons and team surgery are not permitted for this code.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
