Summary & Overview
CPT 23220: Radical Resection of Tumor, Proximal Humerus
CPT code 23220 identifies a radical resection of a tumor from the proximal humerus, a major orthopedic oncology procedure performed to treat primary bone cancer of the upper arm. Nationally, this code is used to document extensive surgical tumor excision and is important for hospital billing, resource planning, and tracking complex cancer care episodes.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the procedure, typical sites of service, and the types of benchmarks and payment issues commonly associated with high-acuity orthopedic oncology surgeries. The analysis covers expected billing considerations, common modifier usage (where applicable), and implications for facility and professional line items.
This publication provides clinicians, billing professionals, and policy analysts with: a clear clinical description of the service represented by CPT code 23220; guidance on where the procedure is typically performed; and the scope of payer engagement nationally. Data not available in the input is noted when applicable. The content focuses on descriptive and procedural context rather than clinical recommendations.
Billing Code Overview
CPT code 23220 describes a radical resection of a tumor from the proximal humerus, an extensive surgical procedure to remove a primary bone malignancy from the upper end of the humerus. The procedure involves wide excision of tumor tissue and surrounding bone to achieve oncologic control.
Service type: Surgical — Orthopedic Oncology
Typical site of service: Inpatient or hospital-based operating room, often within tertiary care centers or specialized cancer hospitals equipped for major orthopedic oncologic surgery.
Clinical & Coding Specifications
Clinical Context
A 48-year-old patient presents with progressive pain, swelling, and limited shoulder range of motion. Imaging (radiographs and MRI) demonstrates an aggressive destructive lesion centered at the proximal humeral metaphysis with cortical breach and a soft-tissue mass. Core needle biopsy confirms a primary malignant bone tumor (eg, osteosarcoma or chondrosarcoma) localized to the proximal humerus. The surgical oncology and orthopedic oncology teams evaluate limb-sparing options versus amputation. After multidisciplinary tumor board review, the patient is scheduled for radical resection of the proximal humerus with intraoperative margin assessment and planning for immediate reconstruction (endoprosthetic replacement or allograft-prosthetic composite).
Preoperative workflow includes staging with CT chest to evaluate for pulmonary metastases, baseline labs, anesthetic evaluation, and consent discussion documenting tumor type, extent of resection, potential neurovascular sacrifice, and reconstruction plan. Intraoperative workflow involves limb positioning, extensile shoulder incision, wide soft-tissue margins, osteotomy of the humerus at a level to achieve negative margins, careful preservation or planned sacrifice of the axillary nerve and vascular structures as indicated, and reconstruction or temporary stabilization. Postoperative care includes pain control, wound monitoring, early physical therapy per oncologic and reconstructive directives, adjuvant chemotherapy or radiotherapy planning as indicated by histopathology, and follow-up imaging for local recurrence and metastasis surveillance.
