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

What 29876 covers

An orthopedic surgeon uses a knee arthroscope and instruments to remove abnormal or inflamed synovial tissue from two or more compartments. This may be performed for substantial synovitis affecting multiple areas of the joint. The procedure is typically done in a hospital outpatient department or ambulatory surgery center; the operative report should identify the treated compartments and describe the synovectomy performed in each.

Choose this code for a major synovectomy involving multiple compartments, rather than a limited synovectomy confined to one compartment. Document the clinical indication, the extent and location of the synovial disease, and any other arthroscopic work. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When related endoscopies are performed together, endoscopy family pricing applies. Modifier 50 is used for a bilateral procedure, paid at 150%. Medicare does not pay for an assistant at surgery; co-surgeons and team surgery are not permitted.
