CPT 28160: Partial Excision of Toe Phalanx or Interphalangeal Joint
CPT code 28160 represents a surgical excision of part of a toe phalanx or removal of an interphalangeal joint to address trauma, infection, or tumor-related pathology. This code captures a focused foot and toe surgical service that affects patient mobility and infection control and can have implications for postoperative rehabilitation and durable medical equipment needs. Nationally, procedures coded with 28160 are relevant to payer coverage policies, bundling decisions, and postoperative quality metrics.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and the payer landscape covered. The publication presents benchmarks and policy-relevant information related to coverage and coding practices, explains common billing considerations connected to surgical toe procedures, and outlines where readers can expect variation in coverage and authorization requirements across major national payers.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old with chronic osteomyelitis of the distal phalanx of the great toe after recurrent paronychia and failed antibiotic therapy. The patient presents to podiatry or orthopedics with localized pain, erythema, drainage, and radiographic evidence of phalangeal bone involvement. After informed consent and preoperative assessment, the patient undergoes surgical partial toe amputation under regional block or local anesthesia in an ambulatory surgical center or hospital operating room. Perioperative workflow includes preoperative antibiotics as indicated, sterile preparation, excision of the infected or necrotic portion of the phalanx or interphalangeal joint, hemostasis, wound closure or delayed closure for infected wounds, and dressing and postoperative instructions. Postoperative care involves pain control, wound checks, activity restrictions, and follow-up for suture removal and assessment of healing. Documentation must record the specific toe and digit side (left/right), the portion removed (distal phalanx, proximal phalanx, or joint), indication (for example, infection, trauma, or tumor), anesthesia type, and any intraoperative complications.
