Official Description

Pericardiocentesis; subsequent

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33011 refers to a subsequent pericardiocentesis, which is a medical intervention aimed at draining excess fluid from the pericardial space surrounding the heart. The pericardium is a double-walled sac that contains the heart and provides it with protection and lubrication. In cases where fluid accumulates in this space, it can lead to complications such as cardiac tamponade, which can impair the heart's ability to function effectively. During this procedure, the physician utilizes a long needle, typically inserted below the sternum, to access the pericardial cavity. Local anesthesia is administered to minimize discomfort for the patient. Once the needle is positioned correctly, fluid is aspirated or withdrawn from the pericardial space. After the necessary amount of fluid has been removed, the needle or catheter is carefully taken out, and a dressing is applied to the site of insertion. It is important to note that this code is specifically designated for subsequent procedures, following an initial pericardiocentesis, which is coded under CPT® Code 33010. This distinction is crucial for accurate medical coding and billing practices.

1. Indications

The indications for performing a subsequent pericardiocentesis, as described by CPT® Code 33011, typically include the following conditions:

  • Recurrent Pericardial Effusion - This occurs when fluid accumulates again in the pericardial space after an initial drainage procedure, necessitating further intervention.
  • Cardiac Tamponade - A condition where the accumulation of fluid exerts pressure on the heart, impairing its ability to pump blood effectively, often requiring repeated drainage.
  • Monitoring of Pericardial Fluid - In some cases, subsequent pericardiocentesis may be indicated to monitor the characteristics of the fluid, especially if there are concerns regarding infection or malignancy.

2. Procedure

The procedure for subsequent pericardiocentesis involves several critical steps to ensure safety and effectiveness:

  • Step 1: Preparation The patient is positioned appropriately, often in a semi-reclined position, to facilitate access to the pericardial space. The area below the sternum is cleaned and sterilized to reduce the risk of infection.
  • Step 2: Anesthesia Local anesthesia is administered to the patient to minimize discomfort during the procedure. This step is crucial for patient comfort and cooperation.
  • Step 3: Needle Insertion A long needle is carefully inserted below the sternum, guided by anatomical landmarks or imaging techniques such as ultrasound, to ensure accurate placement into the pericardial space.
  • Step 4: Aspiration of Fluid Once the needle is in the correct position, the physician aspirates the fluid from the pericardial cavity. The amount and characteristics of the fluid may be assessed during this step.
  • Step 5: Removal and Dressing After the desired amount of fluid has been withdrawn, the needle or catheter is removed. A sterile dressing is then applied to the insertion site to protect it and promote healing.

3. Post-Procedure

After the subsequent pericardiocentesis, the patient is typically monitored for any immediate complications, such as bleeding or infection at the insertion site. Follow-up care may include assessing the patient's symptoms and ensuring that the fluid does not reaccumulate. Depending on the underlying condition that necessitated the procedure, further diagnostic tests or treatments may be required. Patients are often advised to report any unusual symptoms, such as chest pain or shortness of breath, following the procedure.
