Peripheral nerve surgery
About 64727: Microsurgical internal neurolysis
Reports microscope-assisted dissection within a peripheral nerve to free internal fascicles from scar or adhesions during a neuroplasty procedure.
The surgeon uses an operating microscope to separate nerve fascicles from internal scar or adhesions as part of peripheral nerve surgery. This is an intraoperative maneuver performed by surgeons treating peripheral nerve injury or entrapment, commonly in a hospital operating room or ambulatory surgery center. It describes dissection within the nerve, not simply exposing the nerve or freeing it from tissue around its outer surface.
Report 64727 only with a qualifying primary neuroplasty procedure; it is an add-on and is paid within that primary procedure’s global period. The operative report should identify the nerve and site, describe the internal fascicular dissection, and support use of the operating microscope. Do not use it for external neurolysis or decompression alone. The primary procedure accounts for the operative service to which this additional work is attached.

64727 billing questions
Can 64727 be reported by itself?
No. It is an add-on code and must be reported with a qualifying primary neuroplasty procedure.
Does microscope use alone support 64727?
No. The operative work must include internal dissection of nerve fascicles, not merely microscope use or exposure of the nerve.
Is external neurolysis enough to report this code?
No. Freeing a nerve from surrounding tissue without intraneural fascicular dissection does not describe internal neurolysis.
What documentation supports 64727?
Document the nerve and operative site, the internal fascicular dissection performed, and use of an operating microscope, along with the primary neuroplasty.
How does the global period affect this add-on?
CMS pays 64727 within the global period of the primary procedure with which it is reported.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
