Intraventricular pacing

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Intraventricular pacing, as described by CPT® Code 93612, is a specialized medical procedure that involves the use of electrical impulses to modify the heart's rhythm. This technique is essential for assessing the heart's electrical activity and determining the need for further interventions, such as electrophysiological procedures, pacemakers, or other cardiac devices. The procedure typically begins with the selection of one or more access veins, commonly the femoral or jugular veins, which serve as entry points to the cardiovascular system. Prior to the procedure, the skin over these access sites is meticulously prepared to minimize the risk of infection. A needle is then used to puncture the selected veins, followed by the placement of sheaths to facilitate the introduction of catheters. Using continuous fluoroscopic guidance, which provides real-time imaging of the heart and surrounding structures, guidewires are carefully inserted and advanced from the access veins into the heart chambers. Once the guidewires are in place, catheters are advanced over them and positioned specifically within the atria or ventricles of the heart. After the guidewires are removed, the physician initiates the pacing procedure, which involves delivering electrical impulses to stimulate the heart. This pacing is crucial for evaluating the heart's response and determining the appropriate course of action based on the results obtained. Following the procedure, the physician reviews the findings and generates a comprehensive written report detailing the outcomes of the pacing assessment. It is important to note that CPT® Code 93610 should be used when intra-atrial pacing is performed, while CPT® Code 93612 is designated specifically for intraventricular pacing.

1. Indications

The indications for intraventricular pacing (CPT® Code 93612) include the following:

  • Assessment of Heart Rhythm: Intraventricular pacing is performed to evaluate the heart's electrical activity and rhythm, particularly in patients with suspected arrhythmias.
  • Need for Electrophysiological Procedures: This procedure helps determine if a patient requires further electrophysiological interventions based on the pacing results.
  • Pacemaker Evaluation: Intraventricular pacing may indicate the necessity for a permanent pacemaker in patients with bradycardia or other conduction abnormalities.
  • Cardioverter Assessment: The procedure can assist in deciding whether a cardioverter device is needed for patients experiencing tachyarrhythmias.
  • Interventional Device Requirement: It is used to assess the need for other interventional procedures or devices that may be necessary for managing the patient's cardiac condition.

2. Procedure

The procedure for intraventricular pacing involves several critical steps, which are outlined as follows:

  • Access Vein Selection: The physician selects one or more access veins, typically the femoral or jugular veins, to facilitate entry into the cardiovascular system.
  • Skin Preparation: The skin over the chosen access veins is thoroughly cleaned and prepared to reduce the risk of infection during the procedure.
  • Vein Puncture: A needle is carefully inserted to puncture the selected vein, allowing for the introduction of sheaths that will guide the subsequent instruments.
  • Sheath Placement: Sheaths are placed in the punctured veins to provide a pathway for the guidewires and catheters that will be used in the procedure.
  • Guidewire Insertion: Under continuous fluoroscopic guidance, guidewires are inserted through the sheaths and advanced into the heart, ensuring accurate positioning.
  • Catheter Advancement: Catheters are then advanced over the guidewires and positioned specifically within the atria or ventricles of the heart, depending on the clinical objectives.
  • Guidewire Removal: Once the catheters are correctly positioned, the guidewires are removed, leaving the catheters in place for pacing.
  • Pacing Initiation: The physician initiates the pacing procedure by delivering electrical impulses to the heart, which allows for the assessment of the heart's response to pacing.
  • Results Review: After the pacing is completed, the physician reviews the results and prepares a written report detailing the findings and any recommendations for further action.

3. Post-Procedure

Post-procedure care for patients who have undergone intraventricular pacing includes monitoring for any immediate complications, such as bleeding or infection at the access site. Patients are typically observed for their heart rhythm and overall stability following the procedure. The physician will review the pacing results and may discuss the need for additional interventions based on the findings. A follow-up appointment may be scheduled to further evaluate the patient's condition and determine the next steps in their treatment plan. It is essential for healthcare providers to ensure that patients understand the importance of reporting any unusual symptoms or concerns during their recovery period.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
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.
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.
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.)
