CPT code 64713: Nerve revision, major peripheral nerve, arm2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 64713 in California.

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

What 64713 covers

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.
