About 28306: First metatarsal osteotomy
Reports a first metatarsal bone cut used to correct its alignment or length when the work is not included in a broader procedure.
The surgeon makes a controlled cut in the first metatarsal and repositions or reshapes the bone to address a deformity or alignment problem. Orthopedic foot and ankle surgeons and podiatrists commonly perform this work in an operating room. The operative report should identify the bone treated, the deformity, the osteotomy performed, and the correction achieved.
Select this code for the first metatarsal when the documented work is not part of a more comprehensive procedure that includes the osteotomy. Use the graft-specific sibling when an autograft is used. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

28306 billing questions
How does 28306 differ from 28307?
Both address an osteotomy of the first metatarsal. Use 28307 when the procedure includes autograft; 28306 describes the osteotomy without that graft-specific distinction.
Can 28306 be reported with a bunion correction code?
Do not separately report 28306 for an osteotomy already included in a comprehensive bunion correction procedure, such as a procedure that includes a distal metatarsal osteotomy. The operative documentation must support distinct work before separate reporting is considered.
What documentation supports 28306?
Document the first metatarsal as the treated bone, the reason for correction, the osteotomy and any repositioning performed, and the resulting alignment. Identify any autograft, which may point to the graft-specific sibling code.
How is bilateral 28306 reported?
For procedures on both first metatarsals, report bilateral surgery with modifier 50; CMS pays the bilateral procedure at 150%.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. Related routine follow-up during that period is included in the surgical payment.
Can an assistant or co-surgeon be paid?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
