CPT® Code 29848

Surgical endoscopy of the wrist, specifically coded as CPT® 29848, involves a minimally invasive procedure aimed at addressing carpal tunnel syndrome (CTS). This condition arises when the transverse carpal ligament, which forms the roof of the carpal tunnel, becomes thickened or inflamed, leading to compression of the median nerve. The carpal tunnel is a narrow passageway located on the anterior side of the wrist that houses the median nerve along with nine flexor tendons that facilitate movement in the hand. Symptoms of CTS typically include numbness, tingling, and pain that can radiate into the fingers and hand, significantly impacting daily activities and quality of life. During the procedure, two small incisions are made—one on the wrist and another in the palm—to allow for the insertion of an endoscope. This instrument provides direct visualization of the surgical site, enabling the surgeon to accurately cut the transverse carpal ligament with a small blade. The endoscopic approach minimizes tissue damage and promotes quicker recovery compared to traditional open surgery, as it reduces scarring and postoperative pain. After the ligament is released, the endoscope is withdrawn, and the incisions are sutured closed, completing the procedure.
