Official Description

Pericardiocentesis, including imaging guidance, when performed

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33016 is known as pericardiocentesis, which involves the drainage of excess fluid that accumulates around the heart, a condition referred to as pericardial effusion. This procedure is critical in emergency situations, particularly for treating cardiac tamponade, where fluid buildup exerts pressure on the heart, hindering its ability to pump effectively. Pericardiocentesis can be performed using two primary techniques: a 'blind' approach, where the physician relies on anatomical landmarks, or with imaging guidance, which may include modalities such as computed tomography (CT), fluoroscopy, or echocardiography. These imaging techniques enhance the accuracy of the procedure by allowing visualization of the heart and surrounding structures, thereby minimizing the risk of complications. During the procedure, local anesthesia is administered to ensure patient comfort, and the patient is typically positioned either supine or in a semirecumbent position at an angle of 30 to 60 degrees. This positioning helps to bring the heart closer to the anterior chest wall, facilitating access. To further reduce the risk of complications, such as gastric perforation, a nasogastric tube may be inserted. The physician then carefully inserts a long needle through the chest wall into the pericardial space, where the protective tissue surrounding the heart is located. Once the needle is correctly positioned within the pericardium, a catheter and syringe are attached to aspirate the excess fluid. The procedure concludes with the removal of the needle once no further fluid can be aspirated, effectively relieving the pressure on the heart.

1. Indications

The procedure of pericardiocentesis is indicated for several critical conditions related to fluid accumulation around the heart. The following are the primary indications for performing this procedure:

  • Cardiac Tamponade - A life-threatening condition where fluid accumulation exerts pressure on the heart, impairing its ability to pump blood effectively.
  • Pericardial Effusion - The presence of excess fluid in the pericardial space, which may require drainage for diagnostic or therapeutic purposes.
  • Diagnostic Evaluation - To obtain fluid samples for laboratory analysis to determine the cause of the effusion, such as infection, malignancy, or inflammatory conditions.

2. Procedure

The pericardiocentesis procedure involves several critical steps to ensure safe and effective drainage of fluid from around the heart. The following outlines the procedural steps:

  • Step 1: Patient Positioning - The patient is positioned supine or in a semirecumbent position at an angle of 30 to 60 degrees. This positioning is essential as it brings the heart closer to the anterior chest wall, facilitating access to the pericardial space.
  • Step 2: Anesthesia Administration - Local anesthesia is administered to the area where the needle will be inserted, ensuring that the patient remains comfortable throughout the procedure.
  • Step 3: Needle Insertion - A long needle is carefully inserted below the sternum or through the left sternocostal margin. The physician must navigate through the chest wall and into the pericardium, the protective tissue surrounding the heart.
  • Step 4: Fluid Aspiration - Once the needle is correctly positioned within the pericardial space, a small catheter and syringe are connected to the needle. The physician then aspirates the excess fluid, withdrawing it from the pericardial cavity.
  • Step 5: Needle Removal - After the aspiration is complete and no more fluid can be withdrawn, the needle is carefully removed from the chest wall, concluding the procedure.

3. Post-Procedure

After the completion of pericardiocentesis, the patient is typically monitored for any immediate complications, such as bleeding or infection at the insertion site. It is essential to assess the patient's vital signs and overall condition to ensure stability. Depending on the volume of fluid removed and the patient's response, further imaging may be performed to evaluate the effectiveness of the procedure. Patients may also require follow-up care to address the underlying cause of the pericardial effusion and to monitor for any recurrence of fluid accumulation.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
