About 64856: Brachial plexus repair or transposition
Report this service for operative repair or transposition of a brachial plexus nerve, such as reconstruction after a traumatic plexus injury.
This service covers operative repair or transposition of a brachial plexus nerve. It is commonly performed by a neurosurgeon, plastic surgeon, or orthopedic surgeon with peripheral nerve expertise in a hospital operating room. A typical clinical setting is reconstruction of a traumatic brachial plexus injury when the surgeon repairs or repositions the involved nerve structures.
Choose the code based on the documented anatomy and work performed, not simply the diagnosis of plexus injury. The operative report should identify the brachial plexus structures treated and describe the repair or transposition. 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 occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate for this descriptor and anatomy. Medicare does not pay an assistant at surgery for this service; co-surgeons require supporting documentation, and team surgery is not permitted.
