What 28304 covers

This service involves a planned cut in a midfoot tarsal bone, such as a cuneiform, navicular, or cuboid, to change its alignment or shape. Orthopedic foot-and-ankle surgeons and podiatrists perform these procedures to address structural deformity or abnormal foot mechanics, commonly in an operating room. The operated bone distinguishes this service from osteotomy of the calcaneus, talus, or a metatarsal. A tarsal osteotomy with autograft is reported with a different code.

Select this code when the operative work is a midfoot tarsal osteotomy without the autograft service represented by 28305. The operative report should identify the bone and side, the condition being corrected, the osteotomy and correction performed, and whether graft was used. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For same-session multiple procedures, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 bilateral procedures are paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
