What 28298 covers

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.

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.

28298 billing questions

When should 28298 be chosen over a metatarsal osteotomy code?

Choose 28298 when the hallux valgus correction includes an osteotomy of the proximal phalanx. Codes 28295 and 28296 describe correction using an osteotomy at different parts of the first metatarsal.

Is the proximal phalanx osteotomy separately billed?

The proximal phalanx osteotomy is part of the corrective service represented by 28298. Do not report it again as a separate procedure for the same corrective work.

What documentation supports reporting 28298?

The operative report should establish that hallux valgus was corrected with an osteotomy of the great toe’s proximal phalanx and identify the side treated.

How is bilateral performance reported?

CMS pays bilateral performance with modifier 50 at 150%. The code has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
