What 63042 covers

A spine surgeon uses this service to revisit a previously operated lumbar level and relieve recurrent nerve-root compression. The work may include a limited opening in the posterior vertebral bone, partial facet removal, widening the nerve-root exit, and removal of herniated disc material when needed. A typical clinical situation is recurrent leg pain from nerve-root compression at a level treated surgically before. The code represents one lumbar level; additional re-exploration levels are addressed separately when supported.

Report this code when the operative report supports re-exploration at a single lumbar level and describes the nerve-root decompression performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid, and co-surgeons are permitted; team surgery is not permitted.
