CPT® Code 28308

An osteotomy is a surgical procedure that involves cutting and reshaping bones to correct deformities or misalignments. Specifically, CPT® Code 28308 refers to the osteotomy of a metatarsal bone, excluding the first metatarsal, with the possibility of lengthening, shortening, or angular correction. This procedure is typically indicated for patients with acquired or congenital angular deformities of the foot, such as hallux valgus, metatarsus primus varus, hallux varus, or dorsal bunion. The surgery aims to realign the metatarsal bones to restore proper function and alleviate pain. During the procedure, the surgeon exposes the metatarsal bone, and depending on the specific deformity, the surgical approach may involve excising portions of adjacent bones, such as the proximal phalanx or medial cuneiform. The metatarsophalangeal (MTP) joint capsule may also be incised, and tendons may be divided to facilitate the correction. The osteotomy can be performed as a closing wedge or opening wedge procedure, with internal fixation methods employed to maintain the new alignment. This code is specifically used for osteotomies of metatarsals other than the first, ensuring accurate coding and billing for the surgical intervention performed.
