CPT® Code 64835

The CPT® Code 64835 refers to the surgical procedure involving the suture of a single nerve, specifically the median motor nerve in the thenar region of the hand. This procedure is essential for repairing nerve injuries that may occur due to trauma or surgical complications. The median nerve is a critical nerve that controls movement and sensation in the hand, particularly in the thumb and first three fingers. The suture repair of the nerve, often termed end-to-end closure, is a meticulous process that can be performed using various techniques depending on the location and severity of the nerve injury. For injuries located further from the nerve's origin, an epineural closure technique is typically employed, where the outer layer of the nerve, known as the epineurium, is sutured to bring the two ends of the transected nerve together without applying tension. In contrast, for injuries closer to the nerve's origin, a perineural closure technique may be utilized, which involves exposing the individual fascicles of axons within the nerve. This method allows for a more precise alignment and suturing of the fascicles that share similar functions, ensuring optimal recovery of nerve function. The procedure is critical for restoring motor function and sensation, thereby improving the patient's quality of life following nerve injury.
