    CPT 21620: Partial Resection of Sternum (Partial Sternectomy)

    Medicare pays $508 on average nationally for this procedure.

    CPT code 21620 describes partial removal of the sternum (partial sternectomy) performed to treat lesions, abnormal bony protrusions, osteomyelitis, or necrotic sternal bone; this surgical service is a thoracic/osseous procedure typically performed in an operating room or surgical suite, often by thoracic or general surgeons, and involves resection of a portion of the breastbone with appropriate wound management and possible reconstruction measures as clinically indicated.

    Clinical & Coding Specifications

    Clinical Context

    A 62-year-old male with a history of chronic sternal osteomyelitis following prior median sternotomy presents with persistent localized pain, erythema, and draining sinus at the lower sternal incision despite prolonged intravenous antibiotics. Imaging (CT chest) demonstrates sequestrum and focal necrotic portion of the body of the sternum. The cardiothoracic surgical team schedules operative debridement and limited partial sternectomy to remove diseased bone and allow soft-tissue closure with possible muscle flap coverage.

    Preoperative workflow includes history and physical, infection workup with blood cultures, CT imaging to define the extent of bony involvement, anesthesia evaluation, and informed consent documenting the extent of bone resection. Intraoperative documentation should note the exact portion of the sternum removed, indication (infection/necrosis), concurrent procedures (eg, debridement, closure with flap), estimated blood loss, and specimens sent for culture and pathology. Postoperative care includes intravenous antibiotics guided by cultures, wound and flap monitoring, and follow-up imaging as indicated.
