Official Description

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

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A ventricular assist device (VAD) is a sophisticated mechanical pump designed to provide circulatory support for patients suffering from heart failure. This device plays a critical role in managing patients with severe cardiac conditions, particularly those who are not suitable candidates for heart transplantation or those who are awaiting a transplant. The primary function of a VAD is to assist the heart, particularly the left ventricle, in pumping blood effectively throughout the body. In the context of CPT® Code 33990, the insertion of the VAD is performed percutaneously, which means that it is done through the skin using a catheter, rather than through an open surgical procedure. The procedure involves accessing the femoral artery, which is a major blood vessel in the thigh, to introduce the catheter. Under radiological supervision, the catheter is carefully navigated through the vascular system to reach the left ventricle of the heart. This is achieved by advancing the catheter from the femoral artery into the aorta, across the aortic valve, and finally into the left ventricle. Once the VAD is correctly positioned, its internal pump aids the heart by facilitating the movement of blood from the left ventricle into the ascending aorta and subsequently into the peripheral circulatory system. This intervention is particularly vital for patients experiencing end-stage heart disease, as it provides essential support to maintain adequate blood flow and oxygen delivery to vital organs.

1. Indications

The insertion of a ventricular assist device (VAD) is indicated for patients with severe heart failure who require mechanical support to maintain adequate circulation. The following conditions may warrant the use of this procedure:

  • Heart Failure: Patients experiencing advanced heart failure that is not responsive to medical therapy.
  • Bridge to Transplant: Individuals awaiting heart transplantation who need temporary support to sustain their cardiac function.
  • End-Stage Heart Disease: Patients with end-stage heart disease who are not candidates for heart transplantation and require mechanical assistance to improve their quality of life.

2. Procedure

The procedure for the insertion of a ventricular assist device (VAD) involves several critical steps, which are outlined as follows:

  • Step 1: The procedure begins with the patient being positioned appropriately and prepared for the insertion. This includes administering anesthesia and ensuring that the patient is stable for the procedure.
  • Step 2: Access to the femoral artery is obtained, typically through a small incision in the groin area. This access point allows for the introduction of the catheter that will carry the VAD.
  • Step 3: Under radiological supervision, a catheter is advanced from the femoral artery into the aorta. This step is crucial as it guides the catheter through the vascular system toward the heart.
  • Step 4: The catheter is then maneuvered across the aortic valve and into the left ventricle. This precise positioning is essential for the effective functioning of the VAD.
  • Step 5: Once the catheter is in place, the small internal pump at the tip of the catheter is activated. This pump assists the heart by helping to propel blood from the left ventricle into the ascending aorta and into the peripheral circulatory system.
  • Step 6: After confirming the proper placement and functionality of the VAD, the catheter is secured, and the incision site is closed. The patient is then monitored closely for any complications or necessary adjustments.

3. Post-Procedure

Following the insertion of the ventricular assist device, patients typically require close monitoring in a critical care setting. Post-procedure care includes assessing the function of the VAD, monitoring vital signs, and ensuring that there are no complications such as bleeding or infection at the insertion site. Patients may also need adjustments to their medications to optimize heart function and manage any potential side effects of the device. Rehabilitation and follow-up care are essential components of the recovery process, as they help patients adapt to living with a VAD and prepare for any future interventions, such as heart transplantation if applicable.

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).
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
GZ Item or service expected to be denied as not reasonable and necessary
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).
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
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.
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.
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).
