CPT® Code 33019

The procedure described by CPT® Code 33019 involves the pericardial drainage with the insertion of an indwelling catheter using a percutaneous approach, which is guided by computed tomography (CT). The pericardial sac, a delicate two-layer membrane encasing the heart, typically contains a small volume of fluid that serves to minimize friction during heartbeats. However, various conditions such as infections, malignancies, inflammation, injuries, adverse drug reactions, or metabolic disorders can lead to an accumulation of excess fluid, known as pericardial effusion. This excess fluid can exert pressure on the heart, potentially compromising its function. To alleviate this condition, a pericardial drainage procedure is performed. This minimally invasive technique is conducted under local anesthesia, where a needle is carefully inserted through the chest wall into the pericardial space. The needle is advanced through the outer layer of the pericardial sac into the fluid-filled cavity. Once the needle is in place, a thin, flexible catheter is threaded through it and into the pericardial sac, after which the needle is removed. The catheter is then secured to the chest wall using sutures or tape to prevent displacement. Fluid can be aspirated from the pericardial sac either initially with a syringe connected to the catheter or by attaching the catheter to a drainage bag for continuous drainage. The procedure may utilize various imaging modalities for guidance, including ultrasound, fluoroscopy, or CT. Ultrasound guidance requires direct contact with the skin, which may not be feasible in patients with recent cardiothoracic surgeries due to potential obstructions from incisions or dressings. Fluoroscopic guidance, while not requiring skin contact, may lack the necessary field of view or spatial resolution. In contrast, CT guidance offers superior visualization of the thoracic and cardiac anatomy, making it particularly useful for complex cases involving the pericardial sac. CPT® Code 33019 specifically denotes the use of CT guidance for this procedure, distinguishing it from other codes that may involve fluoroscopic or ultrasound guidance.
