CPT 28315: Excision of Sesamoid Bone, First Toe
CPT code 28315 denotes surgical excision of a sesamoid bone beneath the first toe performed as a stand‑alone procedure to relieve pain. Nationally, this code represents a targeted orthopedic/podiatric procedure commonly used when conservative care fails and is relevant for outpatient surgical scheduling, coverage determinations, and procedure-level cost benchmarking. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for when the code is used, typical sites of service, and the common modifiers associated with perioperative billing. The publication summarizes payer coverage patterns, utilization benchmarks, and documentation considerations that affect claim adjudication. It also highlights policy updates and coding nuances that influence whether the procedure is reported as a primary stand‑alone service versus bundled into a broader foot or forefoot surgery. Data not available in the input are noted where applicable. This overview is intended for coding professionals, practice administrators, and clinicians involved in procedural billing and reimbursement strategy.

Clinical & Coding Specifications
Clinical Context
A 48-year-old recreational runner presents with progressive medial first toe pain refractory to conservative care including orthotics, NSAIDs, and activity modification. Physical exam shows focal tenderness over the plantar aspect of the first metatarsophalangeal joint and reduced hallux push-off strength. Weight-bearing radiographs confirm a symptomatic sesamoid fragment beneath the first toe with degenerative change and persistent pain for >6 months. The podiatric surgeon schedules a stand-alone removal of the painful sesamoid to relieve mechanical pain.
Preoperative workflow includes history and medication reconciliation, informed consent documenting risks (infection, nerve injury, loss of toe flexion), and marking the operative toe. The procedure is typically performed under regional block or local anesthesia with sedation in an ambulatory surgery center or hospital outpatient department. Postoperative care includes wound instructions, analgesia, limited weight-bearing in a postoperative shoe, and follow-up for suture removal and rehabilitation to restore toe function.
