CPT code 27888 denotes an ankle-level surgical amputation that removes the foot across the distal tibia/fibula knobs to manage nonhealing wounds caused by infection or ischemia. The procedure includes nerve excision and soft-tissue reconstruction to create a functional stump capable of weight-bearing. This code is clinically significant as rates of limb-threatening infection and peripheral vascular disease contribute to demand for lower-extremity amputation nationally, and appropriate coding affects inpatient and outpatient surgical billing and quality measurement.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the procedure, how the service is documented for claims, and what to expect in terms of typical sites of service. The publication also summarizes benchmarking elements and relevant policy considerations that commonly affect coverage and payment for major lower-extremity amputations. The content is intended to support coding accuracy, administrative workflows, and payer engagement without providing clinical directives.
