Orthopedic surgery
About 23101: Acromioclavicular or sternoclavicular arthrotomy
Open AC or SC joint surgery that includes biopsy, reported when the surgeon opens one of these joints for direct access or tissue sampling.
The surgeon opens the acromioclavicular (AC) or sternoclavicular (SC) joint through an incision to access the joint directly; biopsy is included when performed. Orthopedic surgeons commonly perform this procedure in a hospital or ambulatory surgery center when direct examination or tissue sampling is needed, such as evaluating a suspected joint infection or inflammatory process.
Select the code based on the joint and the documented open procedure, not simply the diagnosis. The operative report should identify the AC or SC joint, side, surgical approach, and whether tissue was sampled. The day-before preoperative visit and 90 days of related postoperative care are included in the global period. For multiple procedures 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 services are not paid; co-surgeons require supporting documentation, and team surgery is not permitted.

23101 billing questions
How is 23101 distinguished from 23100?
23101 is for an open AC or SC joint procedure that includes biopsy; 23100 is for the glenohumeral joint. The operative note should make the joint site clear.
Can the biopsy be reported separately?
Biopsy is included when performed through the arthrotomy reported with 23101. Do not report the same joint tissue sampling as a separate biopsy service.
When is 23106 a closer fit?
23106 describes sternoclavicular arthrotomy with synovectomy. Use the code matching the documented procedure rather than treating a synovectomy as a biopsy.
How is bilateral surgery reported?
When the procedure is performed on both sides, report modifier 50; CMS pays the bilateral procedure at 150%.
Can an assistant-at-surgery claim be submitted?
CMS does not pay an assistant at surgery for this code under the statutory restriction.
What documentation supports 23101?
Document the AC or SC joint, laterality, open approach, and the work performed, including any biopsy. The operative report should distinguish this joint procedure from glenohumeral surgery or clavicle resection.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
