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.

How to choose
- 64712Nerve revision
- 64712 is specific to the sciatic nerve. Use 64708 for a major arm or leg nerve not represented by a more specific nerve code.
- 64713Nerve revision
- 64708 describes the primary major-nerve neuroplasty; 64713 is for each additional major peripheral nerve treated in the same session.
- 64718Ulnar nerve surgery
- 64718 is specific to ulnar nerve neuroplasty at the elbow. Do not use 64708 for that separately specified site and nerve.
- 64721Carpal tunnel release
- 64721 describes the separately specified median nerve procedure at the carpal tunnel, not general neuroplasty of a major arm or leg nerve.
64708 billing questions
When should 64708 be used instead of a named-nerve code?
Use 64708 for neuroplasty of a major arm or leg nerve when a more specific nerve code does not describe the procedure. For example, the sciatic nerve and ulnar nerve at the elbow have separately specified codes.
How is a second major nerve reported?
When another major peripheral nerve is treated in the same session, 64713 describes each additional nerve. Document the additional nerve and the work performed on it.
Does 64708 include related postoperative visits?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can modifier 50 be used when nerves on both sides are treated?
CMS identifies modifier 50 as inappropriate for this code. Report the service based on the documented nerve and procedure rather than treating it as a bilateral code.
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%.
What documentation supports 64708?
The operative report should identify the major peripheral nerve, its arm or leg location, and the neuroplasty performed to free it from surrounding tissue.
