CPT® Code 28110

The procedure described by CPT® Code 28110 refers to an ostectomy, specifically a partial excision of the fifth metatarsal head, commonly known as a bunionette or tailor's bunion. This condition involves the formation of a bony protuberance on the lateral side of the fifth metatarsal head, which can cause discomfort and pain, particularly when wearing shoes. The surgical intervention aims to alleviate these symptoms by removing the excess bone that contributes to the deformity. During the procedure, a longitudinal incision is made on the outer side of the fifth metatarsal head to access the affected area. The joint capsule is then incised, allowing for the creation of a capsular flap, which facilitates better exposure of the metatarsal head. The lateral condyle of the metatarsal head is excised to correct the deformity, and any redundant tissue in the joint capsule is either removed or plicated to ensure proper joint function. Finally, the overlying soft tissues are meticulously closed in layers to promote optimal healing and recovery.
