Carpal Tunnel Release Surgery (Open)

Tennessee rates for HCPCS 64721

This surgery relieves pressure on the median nerve at the wrist by cutting the ligament that forms the roof of the carpal tunnel, performed through a single open incision in the palm or wrist. Releasing the ligament gives the nerve more room and can relieve the numbness, tingling, and hand weakness associated with carpal tunnel syndrome. It is the traditional open surgical approach, as opposed to a related procedure performed through smaller incisions with a camera-guided instrument.
