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

What 29845 covers

An orthopedic or hand surgeon uses a wrist arthroscope and instruments to remove a portion of abnormal synovial tissue lining the joint. The procedure may be performed for persistent wrist synovitis, including proliferative tissue associated with inflammatory disease. It is generally done in an operating room, such as a hospital outpatient department or ambulatory surgery center. The operative report should identify the treated wrist, the synovial abnormality, and the tissue removed.

Select this code when the surgeon performs a partial arthroscopic synovectomy; a complete synovectomy is represented by a different wrist arthroscopy code. Document the extent of tissue removal and any distinct procedures performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When related endoscopies are performed together, endoscopy family pricing applies. For bilateral reporting, modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
