Official Description

Insertion of ventricular assist device, percutaneous, including radiological supervision and interpretation; right heart, venous access only

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 33995 refers to the procedure of inserting a ventricular assist device (VAD) through a percutaneous approach, specifically for the right heart, utilizing venous access only. This procedure is critical for patients experiencing acute right heart failure, a condition that can arise from various complications such as myocardial ischemia, pulmonary embolism, or postcardiotomy syndrome. The right ventricular assist device (RVAD) functions as a mechanical pump that aids in the circulation of blood, effectively supporting the heart's ability to pump blood and relieving pressure on the right side of the heart. The RVAD operates by drawing blood from the right atrium or ventricle and directing it into the pulmonary artery, thereby facilitating oxygenation in the lungs. The insertion of the RVAD is performed using a minimally invasive technique, which involves the placement of two cannulas: one positioned in the right atrium and the other in the pulmonary artery. This procedure is conducted under fluoroscopic guidance, ensuring precise placement of the cannulas. The use of dual catheters allows for effective blood flow management, with one cannula serving as the inflow from the right atrium and the other as the outflow to the pulmonary artery. The procedure is designed to enhance patient outcomes by providing necessary circulatory support during critical episodes of heart failure.

1. Indications

The procedure described by CPT® Code 33995 is indicated for patients experiencing acute right heart failure. This condition may arise due to several underlying issues, including:

  • Myocardial Ischemia - A condition where blood flow to the heart is reduced, preventing the heart muscle from receiving enough oxygen.
  • Pulmonary Embolism - A blockage in one of the pulmonary arteries in the lungs, often caused by blood clots that travel to the lungs from the legs or other parts of the body (deep vein thrombosis).
  • Postcardiotomy Syndrome - A complication that can occur after heart surgery, characterized by a range of symptoms including fever, pleuritic pain, and respiratory distress, which may lead to right heart failure.

2. Procedure

The insertion of a ventricular assist device (RVAD) via a percutaneous approach involves several critical procedural steps:

  • Step 1: Preparation and Heparinization - Prior to the procedure, the patient is prepared, and anticoagulation is initiated with heparin to prevent clot formation during the insertion of the device.
  • Step 2: Venous Access - Access is obtained through the femoral vein, where a flexible venous cannula is inserted over a guidewire. This cannula is advanced to the inferior vena cava, with its tip positioned in the right atrium, serving as the inflow cannula.
  • Step 3: Second Cannula Insertion - A second venous cannula is introduced through the right internal jugular vein. This cannula is advanced to the pulmonary artery, where it will function as the outflow cannula.
  • Step 4: Verification of Positioning - The correct positioning of both cannulas is confirmed using fluoroscopy and transesophageal echocardiogram, ensuring that they are accurately placed for optimal function.
  • Step 5: Connection to the Pump - Once the cannulas are properly positioned, they are connected to a centrifugal flow pump. The flow of blood through the device is then checked to ensure it is functioning correctly.
  • Step 6: Device Removal - When the RVAD is no longer needed, the patient is weaned from the assist device pump action. Anticoagulation is increased during this process, and the cannulas are subsequently removed.

3. Post-Procedure

After the insertion of the ventricular assist device, patients typically require close monitoring for any complications or adverse effects. Post-procedure care includes managing anticoagulation therapy to prevent thromboembolic events and ensuring the proper functioning of the RVAD. Patients may experience a period of recovery as they adjust to the device's support. Follow-up imaging and assessments are often necessary to evaluate the device's performance and the patient's overall cardiovascular status. Additionally, healthcare providers will monitor for signs of infection at the cannula insertion sites and other potential complications related to the procedure.

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).
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
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).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
