28292 Bunion correction Medicare reimbursement rates in Missouri

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.
