CPT 21627 Sternal Debridement Reimbursement | OpenPayer

Summary & Overview

CPT 21627: Sternal Tissue Debridement/Excision

CPT code 21627 represents surgical removal of damaged, diseased, or unhealthy tissue from the sternum (breast bone) to permit regrowth of healthy tissue. This code captures a focused sternal debridement/excision procedure used in cases of infection, nonhealing wounds, osteomyelitis, or other sternal tissue compromise. Nationally, accurate coding of this procedure affects hospital surgical case mix, quality reporting for surgical site management, and appropriate reimbursement for complex thoracic and mediastinal procedures. Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find a concise clinical and billing overview of CPT code 21627, benchmarks for site-of-service utilization, common billing modifiers and claims considerations, and the typical clinical contexts that justify use of the code. The publication outlines documentation elements that support code selection and summarizes payer coverage patterns and payment policy highlights where available. Data not available in the input is noted explicitly in relevant sections.

Billing Code Overview

CPT code 21627 describes a surgical procedure in which a provider removes damaged, diseased, or unhealthy tissue from the sternum (breast bone) to allow healthy tissue to grow. This procedure is a form of debridement or surgical excision focused on the sternum and surrounding mediastinal tissues.

Service type: Surgical debridement/excision of sternal tissue
Typical site of service: Hospital operating room or inpatient surgical setting; may also occur in an ambulatory surgical center when clinically appropriate

Clinical & Coding Specifications

Clinical Context

A typical patient is a 58-year-old male with chronic sternal osteomyelitis following prior median sternotomy for coronary artery bypass grafting who presents with persistent pain, purulent drainage, and non-healing wound over the midline chest. Clinical workflow begins with evaluation by cardiothoracic surgery: history, physical exam, laboratory studies (CBC, inflammatory markers), wound cultures, and imaging (chest radiograph and CT chest) to assess extent of sternal bone involvement. After discussing risks and obtaining informed consent, the patient is taken to the operating room for debridement of necrotic sternal bone and adjacent infected tissue. Intraoperative steps include sterile prep, incision and exposure, removal of diseased sternum (CPT 21627), thorough irrigation, possible placement of antibiotic beads or negative pressure wound therapy, and staged wound closure or reconstruction with soft tissue flap if required. Postoperative care includes targeted IV antibiotics guided by cultures, wound surveillance, pain control, and outpatient follow-up with cardiothoracic surgery and infectious disease teams. Typical site of service is the inpatient operating room within an acute care hospital or ambulatory surgical center when clinically appropriate. Service type: surgical debridement of bone (sternum) for removal of diseased tissue to allow healing of healthy tissue.
