CPT code 27091 designates surgical removal of a total hip prosthesis by breaking methylmethacrylate bone cement, optionally with placement of a temporary spacer. This procedure is an important component of revision hip arthroplasty and prosthesis explantation workflows, often performed for prosthetic failure, infection management, or mechanical complications. Nationally, coding accuracy for explantation procedures affects claims processing, quality measurement, and bundled payment calculations for hip revision episodes.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a clinical and operational overview of the procedure, common billing considerations, and the typical sites of service where 27091 is billed. The publication provides benchmarks and payment context where available, highlights relevant coding relationships, and summarizes policy or coverage factors that commonly influence authorization and reimbursement for hip prosthesis explantation. The material is intended for revenue cycle managers, orthopaedic surgeons, coding professionals, and policy analysts seeking a concise national view of coding and billing implications for explantation of cemented total hip prostheses.
