What 28308 covers

A foot and ankle orthopedic surgeon or podiatric surgeon cuts a metatarsal other than the first to change its length or alignment. The procedure may address a lesser metatarsal that contributes to forefoot pain or abnormal pressure, including metatarsalgia associated with a long or malaligned bone. The bone may be repositioned and stabilized as part of the correction. These operations are commonly performed in an ambulatory surgery center or hospital outpatient department; some are done in an office-based surgical setting.

Select this code for an osteotomy of a lesser metatarsal, rather than an osteotomy of the first metatarsal or a multiple-metatarsal realignment procedure. Document the specific bone, the reason for changing its length or alignment, and the work performed; report the treated lesser metatarsal count as supported by the operative record. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.
