CPT® Code 27325

The procedure described by CPT® Code 27325 refers to a neurectomy of the hamstring muscle, which involves the surgical excision of a segment of the nerve that innervates the hamstring muscle. This intervention is typically performed to alleviate conditions such as clonus, which is characterized by involuntary muscle contractions, or successive spasms of the hamstring muscle. During the procedure, the physician makes a transverse incision across the hamstring muscle, allowing access to the underlying fascia. The fascia is carefully divided to expose the nerves that innervate the muscle. To accurately identify the specific nerve responsible for the muscle spasms, the physician may apply electrical current or gentle pressure, which can induce a muscle spasm, thereby confirming the correct nerve. Once identified, the nerve is divided, effectively severing the connection that transmits electrical impulses to the hamstring muscle, and the excised segment is removed. Finally, the surgical wound is closed, completing the procedure. For similar neurectomy procedures performed on the popliteal or gastrocnemius muscle located behind the knee, CPT® Code 27326 should be used.
