What 64858 covers
This service repairs a divided or injured sciatic nerve by bringing the nerve ends together and suturing them. It is typically performed by a peripheral nerve, neurosurgical, orthopedic, or plastic surgeon in an operating room. The operative report should identify the sciatic nerve injury and document the repair performed, including the site and whether the nerve ends were directly approximated.
Report this code for repair of the sciatic nerve, rather than a repair code for a different major peripheral nerve. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during the following 90 days. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
