Summary & Overview
CPT 21602: Chest Wall Tumor Resection with Rib Reconstruction
Headline: CPT code 21602 covers resection and reconstruction for chest wall tumors involving the ribs. Lead: CPT code 21602 captures surgical management of chest wall tumors that necessitate rib resection and reconstructive work with myocutaneous flaps and bone grafts or prosthetic materials, a high-acuity procedure with implications for surgical planning, resource use, and payer coverage.
CPT code 21602 represents removal of a chest wall tumor that extends into the ribs with immediate reconstruction of the chest wall defect using myocutaneous flaps and bone grafts or prosthetic rib materials. This code is important nationally because it denotes complex oncologic and reconstructive surgery that typically requires multidisciplinary teams, inpatient resources, and specialized surgical expertise. Proper coding affects reimbursement, surgical quality tracking, and care coordination for thoracic oncology patients.
Key payers referenced include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides readers with benchmarks and payer considerations, clinical context for appropriate use, and coding guidance to support claims submission. It summarizes utilization patterns, common billing modifiers (listed separately), and the clinical scenarios where this code is most applicable.
Readers will learn: the clinical scope and service setting of CPT code 21602; typical reconstructive techniques described by the code; high-level policy and coverage themes relevant to major national payers; and where to find related coding references. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 21602 describes excision of a chest wall tumor that involves the ribs with subsequent reconstruction. The procedure includes removal of the tumor and reconstruction of the resultant chest wall defect using myocutaneous flaps and bone grafts or prosthetic materials for the ribs. Lymph node removal in the upper chest area is not part of this code.
Service type: Surgical — chest wall tumor resection with reconstruction
Typical site of service: Hospital operating room or inpatient surgical setting, given the extent of surgical resection and reconstructive procedures involved.
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents with a symptomatic chest wall mass involving the lateral ribs confirmed by imaging and core biopsy as a primary chest wall tumor. The surgical team schedules an excision of the tumor with partial rib resection to achieve clear margins. The operation includes resection of involved soft tissue and segments of one or more ribs, creating a full-thickness chest wall defect requiring reconstruction. Reconstruction is performed using local myocutaneous flaps (for soft-tissue coverage) and rib stabilization using autologous bone grafts or prosthetic materials (meshes, plates, or rib prostheses). Lymph node dissection in the upper chest/axillary region is not performed. The typical workflow includes preoperative imaging (CT or MRI of the chest), anesthesia evaluation, intraoperative resection and reconstruction by a cardiothoracic or thoracic surgical team often with plastic surgery assistance for flap reconstruction, postoperative monitoring in a surgical recovery unit or intensive care unit if respiratory compromise risk exists, pain control, chest tube management as needed, and follow-up imaging to assess chest wall integrity and oncologic control.
