What is thoracentesis used for?

Thoracentesis is a medical procedure specifically designed to remove fluid from the pleural cavity, which is the space between the lungs and the chest wall. This procedure is commonly performed to alleviate symptoms of pleural effusion, a condition characterized by an accumulation of fluid that can impair breathing and cause discomfort. By removing the excess fluid, healthcare providers can relieve pressure on the lungs, improve respiratory function, and facilitate further diagnostic testing if necessary.

This technique is generally guided by ultrasound or physical examination, and it serves both diagnostic and therapeutic purposes. In diagnostic scenarios, the fluid can be analyzed for infections, cancer, or other underlying conditions. In therapeutic contexts, it helps to improve patient comfort and respiratory mechanics. Understanding the primary function of thoracentesis is crucial for those involved in coding and billing for inpatient procedures, as it directly relates to the appropriate assignment of diagnosis and procedure codes.
