Add-On Code

Internal neurolysis, requiring use of operating microscope (List separately in addition to code for neuroplasty) (Neuroplasty includes external neurolysis)

Internal neurolysis, as described by CPT® Code 64727, is a surgical procedure aimed at addressing issues such as scarring and swelling that occur within the outer nerve sheath. This procedure is typically performed in conjunction with a neuroplasty, which involves the incision of the outer nerve sheath using an operating microscope to enhance visualization of the nerve structure. The primary goal of internal neurolysis is to alleviate nerve compression and improve blood flow to the affected nerve. During the procedure, the surgeon inspects the nerve for any signs of swelling. If swelling is present, simply opening the outer sheath can relieve the pressure on the nerve. In cases where scar tissue is identified within the outer sheath, the surgeon meticulously dissects this tissue to restore normal function. It is important to note that the outer sheath is intentionally left open following the procedure to facilitate healing and further reduce the risk of nerve compression.
