Official Description

Intraventricular and/or intra-atrial mapping of tachycardia site(s) with catheter manipulation to record from multiple sites to identify origin of tachycardia (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 93609 refers to the procedure of intraventricular and/or intra-atrial mapping of tachycardia sites, which involves the use of catheter manipulation to record electrical activity from multiple sites within the heart. This procedure is essential for identifying the origin of tachycardia, a condition characterized by an abnormally fast heart rate. During this mapping process, intra-cardiac catheters are strategically placed within the heart chambers to capture detailed electrical signals. The standard technique employed is sequential mapping, where electrode-mounted catheters are repositioned systematically from one location to another within the heart. This allows for the collection of sequential recordings from each site, which are then analyzed to construct a comprehensive mapping of the tachycardia sites. The physician meticulously reviews these recordings and the resulting mapping to determine the precise electrical pathways involved in the tachycardia. A written report is generated to document the findings and support further clinical decision-making. It is important to note that this code is reported separately in addition to the code for the primary procedure performed during the arrhythmia induction process.

1. Indications

The procedure coded as CPT® 93609 is indicated for patients experiencing tachycardia, which may manifest as symptoms such as palpitations, dizziness, or syncope. The mapping is performed to identify the specific sites within the heart that are responsible for the tachycardia, aiding in the diagnosis and management of arrhythmias. This procedure is particularly relevant in cases where the origin of the tachycardia is unclear and requires detailed investigation to guide further treatment options.

  • Tachycardia Symptoms such as palpitations, dizziness, or syncope necessitate mapping to identify the origin of the tachycardia.
  • Unclear Arrhythmia Origin When the source of tachycardia is not readily identifiable, mapping assists in diagnosis and management.

2. Procedure

The procedure begins with the placement of intra-cardiac catheters, which is performed as a separately reportable procedure. Once the catheters are in position, the physician employs a sequential mapping technique. This involves repositioning electrode-mounted catheters from one site to another within the heart chambers. At each site, sequential recordings of the electrical activity are taken. These recordings are crucial for constructing a detailed map of the tachycardia sites. The physician carefully analyzes the collected data to determine the electrical pathways involved in the tachycardia. After completing the mapping, a comprehensive review of the recordings and the constructed map is conducted, culminating in the generation of a written report that outlines the findings and supports clinical decision-making.

  • Step 1: Catheter Placement Intra-cardiac catheters are placed in the heart chambers as part of a separately reportable procedure.
  • Step 2: Sequential Mapping The physician uses a sequential mapping technique, repositioning electrode-mounted catheters from one site to another within the heart.
  • Step 3: Recording Electrical Activity Sequential recordings of electrical activity are taken from each site to gather data on the tachycardia.
  • Step 4: Data Analysis The physician analyzes the recordings to construct a detailed map of the tachycardia sites and identify the electrical pathways involved.
  • Step 5: Report Generation A written report is created to document the findings and support further clinical decision-making.

3. Post-Procedure

After the completion of the intraventricular and/or intra-atrial mapping procedure, patients may be monitored for any immediate complications or adverse effects related to catheter placement. The physician will review the findings from the mapping and discuss potential treatment options based on the identified tachycardia sites. Follow-up care may include additional diagnostic testing or therapeutic interventions, depending on the results of the mapping and the patient's overall clinical condition. It is essential for the healthcare team to provide appropriate post-procedure instructions and ensure that the patient understands the next steps in their care plan.

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.
GC This service has been performed in part by a resident under the direction of a teaching physician
AO Alternate payment method declined by provider of service
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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.
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.)
