Taking or letting out fluids and/or gases from a body part
Procedure Overview
Drainage procedures in the respiratory system remove fluid, air, blood, or pus that has built up somewhere it doesn't belong, most often the pleural space between the lung and chest wall, but also within the lung tissue, bronchi, or trachea. A collapsed lung from trapped air (pneumothorax), an infected fluid collection (empyema), a malignant pleural effusion, or a lung abscess are all situations where drainage restores normal breathing mechanics and relieves pressure that would otherwise compress the lung.
Anatomy & Axis Detail
Lungs, Bilateral
Bilateral lung drainage is coded when purulent or fluid collections within the lung tissue of both lungs are evacuated during the same operative episode, a scenario seen with bilateral abscesses, septic emboli with cavitation, or extensive necrotizing pneumonia. Because each lung is anatomically separate and the procedure typically involves two distinct access points or catheter placements, documentation should confirm that both sides were actually entered rather than one side being aspirated and the other only imaged. Bronchoscopic drainage of both lungs for retained secretions in a ventilated patient can also fall under this body part when material is removed from parenchymal collections rather than simply suctioned from the airway lumen. The bilateral body part value is used only when both lungs are treated in one session.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Coding & Documentation
Documentation needs to specify the exact anatomic site (pleural cavity, specific lobe, trachea, bronchus) and the method: needle aspiration (thoracentesis), tube thoracostomy with a chest tube, or endoscopic drainage during bronchoscopy. A common assignment error is coding a chest tube placement as Drainage when the device is left in for ongoing output rather than a one-time procedure, or conflating a diagnostic thoracentesis with a therapeutic one when the approach and qualifier differ. Coders also need to distinguish whether the drainage was the entire procedure or incidental to a larger surgery, since incidental drainage during a resection is not separately coded.
