About 28298: Hallux valgus correction with phalanx osteotomy
Corrects hallux valgus using an osteotomy of the great toe’s proximal phalanx as part of the bunion operation.
An orthopedic or podiatric surgeon performs this operation to correct hallux valgus by making an osteotomy in the proximal phalanx of the great toe. The bone cut helps adjust toe alignment as part of the bunion correction. The procedure is typically performed in an operating room for a symptomatic deformity selected for surgical treatment.
Report 28298 when the operative technique includes a proximal phalanx osteotomy; the diagnosis alone does not determine code selection. The operative report should describe the hallux valgus correction, the osteotomy, and the side treated. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 results in payment at 150% for bilateral performance. An assistant at surgery may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
