Summary & Overview
CPT 28118: Excision of Calcaneus for Infection or Necrosis
CPT code 28118 represents surgical excision of the calcaneus, a procedure used to treat severe infection or necrosis of the heel bone. Nationally, this code is relevant for acute orthopedic and podiatric surgical care where limb salvage or infection control necessitates partial or complete removal of the calcaneus. It is typically performed in hospital operating rooms and may be associated with inpatient stays depending on clinical severity. Key payers considered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn the clinical context for use of CPT code 28118, the typical sites of service, and the types of cases that prompt billing under this code. The publication also summarizes coverage and payment considerations across major national payers where available, benchmarking practices and identifying policy or billing issues that commonly arise with calcaneus excision procedures. Content addresses coding placement within surgical service lines and offers a concise reference for clinicians, coding professionals, and policy analysts seeking a national perspective on this specialized orthopedic surgical code. Data not available in the input for payer-specific rates, ICD-10 pairings, or related code utilization is noted where applicable.
Billing Code Overview
CPT code 28118 describes a surgical procedure for removal of the calcaneus (heel) bone performed when the bone is infected or necrotic. The procedure involves excision of the calcaneus to manage severe osteomyelitis, progressive bone necrosis, or life- or limb-threatening infection not responsive to conservative care.
-
Service type: Surgical excision / resection of bone (orthopedic surgery)
-
Typical site of service: Hospital operating room or inpatient surgical setting
Clinical & Coding Specifications
Clinical Context
A 58-year-old male with poorly controlled diabetes presents with progressive heel pain, purulent drainage from a chronic plantar ulcer, and signs of systemic infection despite prolonged antibiotics. Imaging (radiograph and MRI) demonstrates osteomyelitis and necrosis of the calcaneus with collapse of the posterior calcaneal cortex. After multidisciplinary evaluation by podiatry/orthopedics and infectious disease, the decision is made to perform a calcaneal excision (28118) to remove the infected/necrotic bone. The clinical workflow includes preoperative optimization (glycemic control, vascular assessment, and culture-directed antibiotics), preoperative anesthesia evaluation, intraoperative removal of the calcaneus with debridement of surrounding infected soft tissue, specimen submission for culture and pathology, and postoperative wound management with possible negative-pressure wound therapy and staged reconstruction or partial foot amputation if needed. Typical perioperative documentation includes indication (osteomyelitis/necrosis), imaging findings, informed consent, operative report detailing extent of bone removal, specimens sent, prosthetic/orthotic plans, and postoperative follow-up for wound healing and antibiotic course monitoring.
