Summary & Overview
CPT 32505: Open Wedge Resection of Lung (Initial Resection)
CPT code 32505 designates an open wedge resection of the lung (initial triangular resection) performed through an incision into the pleural space. This operative code captures the first resection during an open pulmonary wedge procedure and is relevant for surgical, inpatient, and hospital-based billing. Nationally, accurate use of this code affects surgical quality measurement, resource allocation, and claims adjudication for thoracic procedures.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical service captured by the code, typical sites of service, and the common billing context for hospital-based thoracic surgery. The publication summarizes coding benchmarks, common modifier usage (listed separately), and relevant clinical context for providers and billing staff to align documentation with code assignment.
This overview supports hospitals, surgical teams, and revenue cycle professionals seeking clarity on how CPT code 32505 is used in claims, what clinical procedure it represents, and where it is typically performed. Data not available in the input are noted where applicable in detailed sections.
Billing Code Overview
CPT code 32505 describes an open surgical procedure in which the surgeon makes an incision into the pleural space and excises a portion of lung as a triangular wedge during the initial resection. This procedure is a type of wedge resection of the lung performed via an open (thoracotomy) approach.
-
Service type: Open surgical pulmonary resection
-
Typical site of service: Hospital operating room or inpatient surgical suite
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a peripheral pulmonary nodule suspicious for primary lung carcinoma is scheduled for an open wedge resection. After preoperative evaluation (history, chest CT, pulmonary function testing, and anesthesia assessment), the patient is brought to an operating room in an acute care hospital. Under general endotracheal anesthesia, a thoracic surgeon performs a posterolateral thoracotomy to gain access to the pleural space. The provider creates an open surgical incision into the pleural cavity, excises the triangular wedge of lung tissue containing the lesion, and sends the specimen for frozen section and permanent pathology. Hemostasis is secured, chest tube(s) are placed, and the incision is closed. Typical perioperative documentation includes indication (e.g., suspicious pulmonary nodule), consent, operative report with laterality and extent of resection, time in/out, estimated blood loss, specimens removed, and immediate postoperative plan for chest tube management and pain control. Typical site of service is an inpatient or outpatient hospital operating room (ambulatory surgical center use is uncommon for open thoracotomy wedge resection).
