CPT® Code 28160

A hemiphalangectomy or interphalangeal joint excision of the toe involves the surgical removal of the proximal end of the phalanx, which is one of the bones in the toe. This procedure is indicated for various conditions affecting the toe, such as severe arthritis, trauma, or tumors that compromise the integrity of the joint or bone. The surgery begins with an incision made over the affected area, allowing access to the phalanx and the interphalangeal joint. The surgeon carefully incises the joint capsule if the proximal end of the phalanx is to be excised. The procedure requires precision, as the affected phalanx is underscored at the site of transection, and an oscillating saw is utilized to excise the proximal end of the phalanx. Following the excision, the resected bone is removed from the joint capsule, and if the entire joint is excised, the surrounding tendons and ligaments are addressed to ensure proper healing and function. An intramedullary K-wire may be inserted to maintain alignment of the bones during the recovery process. This code, 28160, should be reported for each toe on which the procedure is performed, reflecting the surgical intervention's specificity and scope.
