What 28299 covers

A foot and ankle surgeon performs two bone cuts to correct hallux valgus, the deformity commonly called a bunion. The procedure may address the first metatarsal and proximal phalanx to realign the great toe and improve its position. It is generally performed in an operating room or ambulatory surgery setting for a symptomatic deformity requiring more than one osteotomy.

Report 28299 when the operative plan and record support a double-osteotomy correction, rather than a single osteotomy or a first tarsometatarsal joint fusion. Document the deformity, the bones and sites treated, and the osteotomies performed. The code has 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 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.

28299 billing questions

When should 28299 be selected instead of a single-osteotomy code?

Use 28299 when the hallux valgus correction includes two osteotomies. A correction using only one osteotomy is represented by the applicable single-osteotomy code.

Can the two osteotomies be billed separately?

28299 represents the double-osteotomy correction. Do not separately report a single-osteotomy code for a component of that same correction.

What documentation supports 28299?

The operative report should identify the hallux valgus correction, the bones and sites treated, and both osteotomies performed.

How is bilateral 28299 reported?

For bilateral procedures, report 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.

May an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted for this code.

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.
