Summary & Overview
CPT 28292: Bunionectomy with Possible Sesamoidectomy
CPT code 28292 denotes surgical excision of bone from a bunion (hallux valgus) and may include removal of the sesamoid bones beneath the first metatarsophalangeal joint. This procedure is a common foot and ankle operation addressing pain, deformity, and impaired function; it is relevant nationally due to its frequency in orthopedic and podiatric practices and its implications for surgical scheduling, supply use, and anesthetic care. Key payers considered in discussions of utilization and payment practice include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will gain a concise clinical and billing profile of CPT code 28292, including the typical service setting, common clinical indications, and the types of benchmarks and policy topics commonly linked to procedural foot surgery (coverage criteria, site-of-service considerations, and payer-specific prior authorization practices). The summary provides context for how this code is used in ambulatory surgery centers versus inpatient settings, what factors influence coding and billing decisions, and which metrics and policy updates are most relevant for clinicians, billing professionals, and payers. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 28292 describes surgical removal of bone from a bunion, a deformity at the first metatarsophalangeal joint that produces a bony prominence near the base of the big toe. The procedure may include excision of the sesamoid bones when clinically indicated.

-
Typical site of service: Outpatient ambulatory surgery center or inpatient hospital operating room, depending on clinical complexity and patient factors
Clinical & Coding Specifications
Clinical Context
A 56-year-old ambulatory female presents to a podiatric surgery clinic with progressive medial prominence at the first metatarsophalangeal (MTP) joint, pain with shoe wear, and callus formation. Conservative measures including shoe modification, orthotics, and NSAIDs have failed. Examination shows a hallux valgus deformity with lateral deviation of the hallux and a palpable bony prominence over the first MTP joint. Preoperative weight-bearing radiographs confirm mild-to-moderate hallux valgus without severe arthritic joint space loss.
The patient is scheduled for an operative bunionectomy with exostectomy (removal of the dorsal/medial bony prominence) and possible sesamoid bone debridement under regional or general anesthesia. Typical workflow: preoperative evaluation and informed consent in clinic, pre-op anesthesia evaluation, procedure performed in an ambulatory surgery center or hospital outpatient department, postoperative recovery with discharge instructions for weight-bearing status and follow-up wound checks in clinic. Intraoperative documentation includes laterality, specific bones removed (metatarsal exostectomy and any sesamoid excision), anesthesia type, estimated blood loss, complications, and implants if used. Postoperative coding is based on the primary procedure 28292, with appropriate modifiers for laterality, multiple procedures, professional vs technical component, or unusual circumstances documented.
