CPT® Code 27326

The procedure described by CPT® Code 27326 refers to a neurectomy of the popliteal region, specifically targeting the gastrocnemius muscle. In simpler terms, this surgical intervention involves the excision of a segment of the nerve that supplies the hamstring muscle. The primary objective of this procedure is to alleviate conditions such as clonus, which is characterized by involuntary muscle contractions, or successive spasms of the muscle. During the operation, the physician makes a transverse incision across the hamstring muscle, allowing access to the underlying fascia. This fascia is then divided to reach the nerves that innervate the muscle. To accurately identify the correct nerve for excision, the physician may apply electrical current or gentle pressure, which can induce a muscle spasm, thereby confirming the nerve's role in muscle innervation. Once the appropriate nerve is located, it is divided, effectively severing the transmission of electrical impulses to the muscle, and subsequently removed. The procedure concludes with the closure of the wound, ensuring proper healing and recovery.
