What 28302 covers

This service is a corrective cut through bone at the ankle, allowing the surgeon to change alignment for an angular deformity. Orthopedic foot-and-ankle surgeons and podiatrists perform it in an operating room; the bone may be stabilized with internal fixation as part of the osteotomy. It is distinct from cuts directed to the heel, other tarsal bones, or metatarsals.

Report 28302 for the ankle-site osteotomy, not simply for ankle exposure or fixation without the corrective bone cut. The operative report should identify the treated side and site, the deformity and correction, and whether fixation was used. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, 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 made; co-surgeons require supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

28300Heel osteotomyCalcaneus realignment
Use 28300 when the osteotomy is directed to the calcaneus. Code 28302 is for the ankle-site osteotomy.
28304Midfoot osteotomyWithout bone graft
Use 28304 for an osteotomy of a tarsal bone other than the calcaneus or talus; 28302 identifies the ankle site.
28305Midfoot osteotomyWith autograft
Code 28305 describes a tarsal osteotomy with autograft. Select 28302 for an ankle-site osteotomy, not based solely on whether graft is used.

For a bilateral procedure, CMS pays 150% when modifier 50 is used.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be made. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
