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.

How to choose
- 64702Nerve neuroplasty
- Choose 64702 for a digital nerve in a finger or toe. Code 64704 applies to a nerve in the hand or foot that is not classified as a finger or toe nerve.
- 64708Nerve neuroplasty
- Code 64708 covers a nerve in the arm or leg. Code 64704 is limited by site to a nerve in the hand or foot.
- 64721Carpal tunnel release
- Code 64721 is specific to carpal tunnel surgery involving the median nerve. Use 64704 for a different hand or foot nerve neuroplasty.
- 64727Internal neurolysis
- Code 64727 describes internal neurolysis as an add-on service, not the primary hand or foot nerve neuroplasty represented by 64704.
64704 billing questions
How does this differ from code 64702?
Code 64702 is for neuroplasty of a digital nerve in a finger or toe. Use 64704 for a nerve in the hand or foot that is not represented by that digital-nerve code.
Is this the code for carpal tunnel release?
No. Carpal tunnel surgery has a specific code, 64721. Use 64704 when the documented neuroplasty is for a hand or foot nerve outside that separately specified procedure.
What documentation supports reporting this procedure?
Document the nerve and its hand or foot location, the scar or adhesions restricting it, and the operative release performed. A diagnosis of nerve symptoms alone does not establish that neuroplasty was performed.
Can modifier 50 be used for treatment on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code. Document the treated side or sides, but do not use modifier 50 for 64704.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. Unrelated services during that period are not described by this global-care rule.
How are other procedures in the same session paid?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
