Official Description

Insertion of a single transvenous electrode, permanent pacemaker or implantable defibrillator

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33216 involves the insertion of a single transvenous electrode for a permanent pacemaker or implantable defibrillator. This procedure is essential for patients who require cardiac pacing or defibrillation due to various heart conditions. Initially, the existing electrode wire(s) of the device are assessed for functionality; if any are found to be defective, they are removed. A new electrode wire is then inserted and carefully positioned within the heart, specifically in either the right atrium or the right ventricle, depending on the patient's needs. This new wire is subsequently reattached to the existing pulse generator, which is the device that delivers electrical impulses to the heart. The procedure necessitates a surgical incision in the upper chest to access a vein, such as the cephalic, subclavian, or jugular vein, through which the electrode wire is advanced into the heart under radiological guidance. This meticulous process ensures that the electrode is correctly placed against the heart wall, allowing for effective pacing or defibrillation. It is important to note that this code specifically pertains to single chamber devices, while a different code, CPT® 33217, is designated for dual chamber devices that utilize two electrode wires.

1. Indications

The procedure associated with CPT® Code 33216 is indicated for patients who require the implantation of a single transvenous electrode due to various cardiac conditions. These may include:

  • Bradycardia: A condition characterized by an abnormally slow heart rate, which may necessitate pacing to maintain adequate heart function.
  • Heart Block: A condition where the electrical signals in the heart are delayed or blocked, leading to ineffective heartbeats that may require pacing intervention.
  • Cardiac Arrest: Situations where the heart stops beating effectively, potentially requiring an implantable defibrillator for emergency pacing or defibrillation.
  • Syncope: Episodes of fainting or loss of consciousness due to transient heart rhythm disturbances that may be corrected with pacing.

2. Procedure

The procedure for the insertion of a single transvenous electrode involves several critical steps:

  • Step 1: The procedure begins with the assessment of the existing electrode wire(s) of the permanent pacemaker or implantable defibrillator. The physician tests these wires to determine their functionality. If any wires are found to be defective, they are removed to ensure the integrity of the pacing system.
  • Step 2: Following the removal of any defective wires, a new electrode wire is prepared for insertion. The physician makes an incision in the skin of the upper chest to access a suitable vein, which may include the cephalic, subclavian, or jugular vein.
  • Step 3: A sheath is then inserted into the selected vein, allowing for the advancement of the pacemaker wire. Under radiological guidance, the new electrode wire is carefully threaded through the sheath and into the appropriate heart chamber, either the right atrium or the right ventricle.
  • Step 4: Once the wire is positioned, it is placed against the wall of the heart chamber to ensure optimal contact for effective pacing. If a dual chamber device is indicated, a second wire is threaded to the selected chamber and positioned similarly against the heart wall.
  • Step 5: After the leads are positioned, they undergo testing to verify their proper functioning. This step is crucial to ensure that the electrode will effectively deliver electrical impulses as needed.
  • Step 6: Finally, the lead(s) are connected to the existing pulse generator, and the generator itself is tested to confirm that it is operational and ready to provide the necessary pacing or defibrillation.

3. Post-Procedure

Post-procedure care for patients who have undergone the insertion of a single transvenous electrode includes monitoring for any complications such as infection, lead displacement, or improper functioning of the device. Patients are typically observed for a period to ensure that the electrode is functioning correctly and that the heart is responding appropriately to the pacing. Follow-up appointments are essential to assess the performance of the pacemaker or defibrillator and to make any necessary adjustments. Patients may also receive instructions regarding activity restrictions and signs of potential complications that should prompt immediate medical attention.

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).
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.)
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
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.
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.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
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.
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.)
