CPT code 64704: Nerve neuroplasty, hand or foot nerve2026 Medicare rate & RVUs

Medicare pays $308.29 for 64704 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 64704 covers

The surgeon exposes a nerve in the hand or foot and releases it from restrictive scar tissue or adhesions. This external neurolysis, also called neuroplasty, may be performed by a hand surgeon, orthopedic surgeon, plastic surgeon, or peripheral nerve surgeon when a nerve is tethered or compressed in the operative area. The code is for a hand or foot nerve, rather than a digital nerve of a finger or toe or a nerve at a separately specified site such as the carpal tunnel.

Choose the code from the nerve’s location and the work documented, not simply from a diagnosis of neuropathy. The operative report should identify the nerve, the hand or foot site, the tethering or scarring, and the release performed. 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 is paid in full and other procedures are subject to the standard reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
