What 28292 covers

This operation corrects hallux valgus using resection at the base of the great toe’s proximal phalanx, often described as a Keller-type procedure. A foot and ankle surgeon or podiatric surgeon may perform it for a painful bunion deformity, including cases where the operative plan calls for removing part of the phalanx rather than correcting the deformity with a metatarsal osteotomy or fusion. Sesamoidectomy is included when performed as part of the correction. The service is commonly performed in an ambulatory surgery center or hospital outpatient setting.

Select the code from the procedure documented, not the bunion diagnosis alone. The operative report should establish the phalangeal-base resection and describe the correction performed, laterality, and any sesamoid work. It 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 the same session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

28292 billing questions

What operative detail supports 28292?

The report should document hallux valgus correction that includes resection at the base of the proximal phalanx. The diagnosis of bunion or a description of prominence removal alone does not establish this procedure.

Is sesamoidectomy separately reported?

Sesamoidectomy is included when performed as part of this hallux valgus correction.

How does 28292 differ from 28298?

28292 involves resection at the proximal phalanx base. 28298 is the hallux valgus correction code for a proximal phalanx osteotomy.

How is bilateral surgery paid?

When the procedure is performed bilaterally and reported with modifier 50, CMS pays 150%.

What postoperative care is included?

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

Can an assistant or co-surgeon be paid?

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.
