CPT® Code 28055

The procedure described by CPT® Code 28055 refers to a neurectomy performed on the intrinsic musculature of the foot. A neurectomy is a surgical procedure that involves the removal of a segment of a nerve, which is typically indicated to alleviate pain or discomfort caused by nerve entrapment or irritation. In this specific case, the procedure targets the intrinsic muscles of the foot, which are responsible for various movements and stability of the toes. The surgery is conducted under magnification to enhance precision and minimize damage to surrounding tissues. A straight midline incision is made on the dorsal aspect of the foot, specifically in the web space between the metatarsal bones. This incision allows access to the underlying structures, where the surgeon dissects through the tissue down to the fascia, identifying and dividing the transverse metatarsal ligament. The metatarsal heads are then manipulated to expose the nerve, which is carefully dissected to its bifurcation. If present, any inflamed bursa may also be excised during the procedure. The ultimate goal of the neurectomy is to sever the nerve's connection to the muscle tissue, thereby interrupting the transmission of electrical impulses that may be causing pain or dysfunction. After the nerve is removed, the surgical site is meticulously cleaned and repaired to promote optimal healing.
