What 28296 covers

Code 28296 covers hallux valgus correction centered on an osteotomy near the head of the first metatarsal. An Austin or chevron bunionectomy is a familiar example. An orthopedic foot and ankle surgeon or podiatric surgeon typically performs the operation in a hospital outpatient department or ambulatory surgery center. The surgeon repositions the bone to improve great-toe alignment and may perform associated soft-tissue work as part of the correction.

Select 28296 when the operative report documents a distal first metatarsal osteotomy for the bunion correction. The report should identify the side, osteotomy location, bone repositioning, and any additional osteotomy. A proximal metatarsal osteotomy, joint fusion, or double osteotomy points to another code. CMS assigns a 90-day global period that includes the day-before preoperative visit and related postoperative care. When multiple procedures are performed in one session, CMS pays the highest-valued procedure in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation. 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.

28296 billing questions

How is 28296 distinguished from 28295?

Both involve first metatarsal osteotomy for hallux valgus, but 28296 identifies an osteotomy at the distal metatarsal; 28295 identifies one at the proximal metatarsal.

What if the surgeon also performs a proximal phalanx osteotomy?

Review the operative report for a double osteotomy. Code 28299 describes hallux valgus correction using two osteotomies, rather than the single distal metatarsal osteotomy represented by 28296.

Is removal of the bunion prominence separately reported?

When removal of the medial prominence is part of the distal metatarsal osteotomy correction, it is included in 28296 rather than reported as a separate bunion procedure.

How is surgery on both feet reported?

CMS recognizes bilateral reporting of 28296 with modifier 50 and pays it at 150%. The operative report should document the distal metatarsal correction on each foot.

What postoperative visits are included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care for the bunion correction.

Can another surgeon participate in the operation?

An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; CMS does not permit team surgery for 28296.

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.
