Operation Definition

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: Percutaneous

Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.

Device: Drainage Device

Drainage Device denotes a device such as a tube or catheter left in place to remove fluid, blood, or air from a body part or cavity following a procedure. It is distinguished from Monitoring Device, which senses and records physiologic data rather than evacuating substances from the body.

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.

Commonly Confused With

ExcisionExcision is confused with Drainage when a pleural biopsy is taken alongside fluid removal - only the tissue-cutting portion is Excision.
ExtirpationExtirpation is the right choice instead of Drainage when the material removed is solid, such as a blood clot or thick mucus plug, rather than free-flowing fluid or gas.
