CPT code 64708: Nerve neuroplasty, major arm or leg nerve2026 Medicare rate & RVUs

Medicare pays $464.27 for 64708 nationally in a facility.

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

What 64708 covers

This service involves surgically freeing a major peripheral nerve in an arm or leg from surrounding scar tissue, adhesions, or constricting tissue. It is generally performed by a surgeon when nerve entrapment or scarring requires operative release. The code covers major nerves not identified by a more specific code, such as the separately specified sciatic or ulnar nerve procedures.

Select the code based on the nerve treated and the work documented, including the operative site and release performed. For additional major peripheral nerves treated in the same session, 64713 may describe the additional nerve. This major surgery code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
