The procedure described by CPT® Code 28294 pertains to the surgical correction of hallux valgus, commonly known as a bunion. This condition involves a deformity of the big toe, where it deviates towards the second toe, often resulting in pain and discomfort. The correction may involve a sesamoidectomy, which is the removal of the sesamoid bones located beneath the big toe joint, and is performed with tendon transplants, specifically utilizing a Joplin type procedure. This surgical intervention aims to realign the toe and alleviate symptoms associated with the bunion deformity. The Joplin bunionectomy is characterized by the transplantation of the extensor tendon of the great toe, which is crucial for restoring proper function and stability to the toe. The procedure is typically performed through a dorsal incision over the metatarsophalangeal joint, allowing the surgeon to access the joint and surrounding structures effectively. The surgical steps involve careful dissection of soft tissues, excision of the medial eminence, and fusion of the metatarsophalangeal joint, ultimately leading to improved alignment and function of the toe.
