Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 23066 covers

This code represents operative sampling of deep soft tissue in the shoulder area for diagnostic evaluation, such as assessment of an indeterminate mass or other abnormal tissue. An orthopedic surgeon or other surgeon exposes the target tissue and removes a specimen for examination. It is distinct from a superficial shoulder-tissue biopsy and from an operation that removes the entire lesion. The service is generally performed in an operating room or other surgical setting.

Select the code based on the documented depth and the fact that tissue was sampled rather than the full lesion excised. The operative report should identify the shoulder site, the deep tissue sampled, and the biopsy performed. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed 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%. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.
