CPT® Code 28292

Correction, hallux valgus with bunionectomy, with sesamoidectomy when performed; with resection of proximal phalanx base, when performed, any method

The procedure described by CPT® Code 28292 pertains to the surgical correction of hallux valgus, commonly known as a bunion. Hallux valgus is a deformity characterized by the lateral deviation of the great toe, which often results in the formation of a bony prominence at the base of the toe, referred to as a bunion. This condition can lead to pain, discomfort, and difficulty in wearing shoes. The surgical intervention involves a bunionectomy, which is the excision of the medial eminence of the metatarsal bone, and may also include a sesamoidectomy if necessary. The procedure may further involve the resection of the base of the proximal phalanx, depending on the specific requirements of the case. The surgical approach typically includes making an incision over the medial aspect of the metatarsophalangeal joint, followed by careful dissection of the soft tissues to expose the joint capsule. The joint capsule is then incised to allow access to the medial eminence, which is excised in alignment with the metatarsal shaft. If the sesamoid bones, which are small bones located beneath the first metatarsal head, are found to be fractured or inflamed, they may also be removed during the procedure. The final steps involve stabilizing the toe's position using K-wires and closing the soft tissues and skin in layers to promote proper healing.
