Summary & Overview
CPT 21820: Manipulation of Sternal Fracture
CPT code 21820 describes manipulation of a sternal fracture — a procedural intervention to restore alignment of the breastbone after blunt or penetrating chest trauma. Nationally, the code captures a relatively uncommon but clinically significant procedure tied to thoracic trauma care, where timely management can affect respiratory mechanics and pain control. This coding entry matters for hospital billing, trauma service lines, and payer adjudication for acute injury care.
Key payers in coverage and benchmarking include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of what the code represents, typical sites of service, and payer scope. The full publication provides benchmarks for utilization and reimbursement, discussion of clinical context and care pathways for sternal fractures, and any recent policy or guideline updates affecting procedural coding and coverage determinations.
This summary is intended for clinicians, coding professionals, and payer policy staff seeking a national-level orientation to CPT code 21820 and its role in trauma and thoracic procedural billing.
Billing Code Overview
CPT code 21820 describes manipulation of a sternal fracture (breastbone) performed by a provider to treat a fracture resulting from trauma to the chest. The service typically involves closed manual manipulation techniques to restore alignment and stability of the sternum following injury.
-
Service type: Procedural manipulation for fracture management
-
Typical site of service: Hospital inpatient or emergency department, and may occur in outpatient surgical or procedural settings depending on clinical severity and care pathways
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who sustained blunt chest trauma, such as from a motor vehicle collision, fall from height, or direct blow during an industrial accident, presenting with anterior chest pain, localized tenderness over the sternum, and possible instability or palpable deformity. Initial evaluation in the emergency department or trauma bay includes airway/breathing/circulation assessment, chest radiography and/or CT scan to confirm a sternal fracture and assess for associated thoracic injuries (e.g., rib fractures, pneumothorax, cardiac contusion). When the fracture is displaced or causes persistent severe pain or respiratory compromise, the orthopedic or thoracic surgery team performs closed or open manipulation and stabilization of the sternum. The procedure typically occurs in an operating room or procedure suite under monitored anesthesia care or general anesthesia with fluoroscopic guidance as needed. Intra-procedural documentation includes indication, informed consent, anesthesia type, technique of manipulation or fixation, any implants used, estimated blood loss, and post-procedure neurovascular and respiratory status. Postoperative care involves pain control, respiratory therapy, monitoring for wound or hardware complications, and outpatient follow-up with imaging to confirm alignment and healing.
