Summary & Overview
CPT 32555: Image-Guided Pleural Drainage (Needle or Catheter)
CPT code 32555 identifies an image-guided pleural drainage procedure in which fluid, blood, or air is aspirated from the space between the lungs and chest wall using a needle or catheter under imaging guidance. This code is used across acute and ambulatory settings when radiologic visualization is required to safely access the pleural space. Nationally, the code matters because image-guided thoracentesis is a common, sometimes urgent procedure for patients with pleural effusion, hemothorax, or pneumothorax and is associated with quality and safety considerations tied to imaging use and site of service.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find operational and clinical context for CPT code 32555, including typical sites of service, common clinical indications, and the role of imaging guidance. The publication outlines benchmark themes and payment policy considerations relevant to hospitals, ambulatory surgical centers, and radiology departments. It also summarizes coding context that affects billing workflows and documentation expectations.
This concise overview is intended for revenue cycle leaders, clinicians who perform pleural procedures, and policy analysts seeking a national perspective on coding and service delivery for image-guided pleural drainage.
Billing Code Overview
CPT code 32555 describes a procedure in which a clinician removes fluid, blood, or air from the pleural space (the area between the lungs and chest wall) using a needle or catheter while employing imaging guidance. This procedure is an image-guided pleural drainage or thoracentesis performed with radiologic assistance.
-
Service type: Image-guided pleural fluid/air drainage (needle or catheter-based pleural drainage)
-
Typical site of service: Hospital inpatient or outpatient setting, ambulatory surgical center, or radiology suite where imaging guidance (ultrasound, fluoroscopy, or CT) is available.
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient presents to the emergency department with progressive shortness of breath and pleuritic chest pain after a recent thoracic procedure. Imaging (chest X-ray and chest ultrasound) demonstrates a moderate to large pleural effusion with associated respiratory compromise. The interventional pulmonologist or radiologist performs a thoracentesis with image guidance to remove pleural fluid for therapeutic relief and diagnostic sampling. The clinical workflow includes informed consent, review of coagulation status and anticoagulant medications, sterile preparation, ultrasound localization of the effusion, percutaneous insertion of a needle or catheter into the pleural space under real-time imaging guidance, aspiration of fluid for symptomatic relief and laboratory studies (cell count, chemistry, culture, cytology), post-procedure imaging to assess for pneumothorax, and documentation of fluid volume, appearance, and any immediate complications. Typical monitoring includes vital signs and pulse oximetry during and after the procedure. The typical site of service is an acute care hospital (emergency department or inpatient ward) or an outpatient ambulatory surgery center or radiology suite equipped for image-guided procedures.
