CPT® Code 64870

Deleted

The CPT® Code 64870 refers to the surgical procedure known as facial-phrenic anastomosis, which is a type of facial nerve reconstruction. This procedure is performed to restore function to the facial nerve by connecting it to the phrenic nerve. The phrenic nerve, which originates from the cervical spinal cord, is primarily responsible for innervating the diaphragm and facilitating breathing. In this context, it is utilized as a donor nerve to reinnervate the facial nerve, which may have been damaged due to injury or disease. The surgical approach involves making an incision near the ear, allowing access to the facial nerve, and carefully dissecting the surrounding tissues to identify and isolate the phrenic nerve. The procedure aims to create a functional connection that can help restore facial movement and expression, which is critical for both aesthetic and functional purposes. The detailed steps of the procedure involve meticulous dissection and anastomosis techniques to ensure a successful outcome.
