CPT® Code 28150

The procedure described by CPT® Code 28150 refers to a phalangectomy of the toe, which involves the surgical removal of a phalanx, or bone segment, from each toe. This intervention is primarily indicated for patients experiencing severe malalignment of the metatarsophalangeal joint, which can lead to conditions such as underlapping, overlapping, or cock-up deformities of the toe. The term 'phalangectomy' specifically denotes the excision of bone rather than soft tissue, distinguishing it from an amputation. During the procedure, a dorsal Z-type incision is utilized to address underlapping toes, while a volar elliptical incision is employed for overlapping or cock-up toes. The surgical approach typically involves the excision of the proximal phalanx, which is the bone closest to the foot. Additionally, the procedure entails incising the joint capsules of both the metatarsophalangeal and proximal interphalangeal joints, followed by the removal of the phalanx. As part of the surgical technique, the flexor and extensor tendons may be released as necessary to facilitate proper alignment and function. To ensure stability and alignment of the remaining bones, an intramedullary K-wire may be inserted into the middle and distal phalanges as well as into the metatarsal bone. This procedure is reported using the CPT® Code 28150 for each toe that undergoes the phalangectomy.
