CPT code 28420 represents open surgical repair of a calcaneal (heel bone) fracture with cancellous bone grafting, a complex orthopedic procedure used when fractures require direct reduction and biological augmentation. This code captures both the fixation of the calcaneus—using screws, nails, or other implants—and the separate harvest and placement of a cancellous graft, commonly from the iliac crest. Nationwide, accurate coding for this service is important for clinical communication, quality measurement, and payment for complex lower-extremity trauma care.

Key payers addressed in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise national overview of what CPT code 28420 covers, typical sites of service, and the clinical context in which it is used. The publication outlines benchmarking metrics, common billing and documentation considerations, and recent policy or coding guidance that affect claims processing and allowable services. The content is intended for coding professionals, orthopedic surgeons, and revenue cycle staff seeking a practical reference for clinical documentation and payer expectations related to open calcaneal fracture repair with bone grafting.
