Peripheral nerve surgery
About 64713: Open revision of major arm nerve
Reports open revision of a major peripheral nerve in the arm when prior surgery or injury leaves a nerve requiring operative correction.
This code describes open revision surgery on a major peripheral nerve in the arm. A surgeon may explore and revise a nerve affected by recurrent compression, scar tethering, or another problem after prior surgery or injury. It is typically performed by an orthopedic, hand, or peripheral nerve surgeon in a hospital operating room or ambulatory surgery center. The operative report should identify the nerve and arm, the reason revision is needed, prior treatment when relevant, and the work performed to address the problem.
Report this code for the arm nerve revision service, rather than a code that specifies a different nerve or site. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures 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; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

64713 billing questions
How does this code differ from 64708?
64713 is for revision of a major nerve in the arm. Use 64708 when the performed neuroplasty falls within that code’s broader arm-or-leg service rather than this arm revision service.
Should a specific nerve code be used instead?
When the operation is specifically a revision of the ulnar nerve at the elbow or wrist, compare 64718 or 64719, respectively. The operative site and actual procedure determine the appropriate code.
What documentation supports reporting 64713?
Document the arm nerve treated, the reason revision was necessary, relevant prior surgery or injury, and the operative steps. The record should make clear that the service was a revision rather than a different nerve procedure.
How is related postoperative care handled?
CMS assigns a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How does CMS handle bilateral reporting and other procedures in the same session?
Bilateral reporting with modifier 50 is paid at 150%. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are paid at 50%.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
