Official Description

Electrocardiogram, 64 leads or greater, with graphic presentation and analysis; tracing and graphics only, without interpretation and report

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 0179T refers to an advanced electrocardiogram (ECG) procedure that utilizes 64 leads or more to capture detailed cardiac electrical activity. This procedure is designed to provide a comprehensive graphic presentation and analysis of the heart's electrical signals, specifically focusing on the tracing and graphics without the inclusion of interpretation and report. The standard 12-lead ECG is commonly used to monitor and diagnose various cardiac conditions; however, the addition of more leads enhances the ability to visualize and analyze the heart's electrical activity more accurately. This is particularly beneficial in diagnosing conditions such as myocardial infarction, ventricular tachycardia, and ventricular fibrillation, which are associated with an increased risk of sudden cardiac death, as well as atrial arrhythmias. The placement of the additional leads is strategically determined based on the suspected cardiac condition, allowing for optimal recording of electrical activity. The physician typically reviews a separately reportable 12-lead ECG to assess whether a more extensive 64-lead or greater ECG is warranted for a definitive diagnosis. During the procedure, leads are placed on both the chest and back, either uniformly distributed or concentrated in specific areas, such as over the heart, to ensure comprehensive coverage. The resulting 64-lead ECG generates both an ECG tracing and a graphic representation, which is stored for later processing. This graphic presentation takes the form of a torso body map, which helps localize the area of concern. By analyzing the ECG tracing alongside the graphic representation, the physician can identify the specific lead(s) that provide critical diagnostic information. Any abnormalities detected in the ECG tracing are meticulously noted and characterized. The data from the separately reportable 12-lead ECG, the 64-lead ECG, the graphic torso map, and the stored data are compiled for further analysis. It is important to note that while CPT® Code 0179T is used for the tracing and graphic presentation only, the complete study, including analysis and interpretation, is reported with CPT® Code 0178T, and the interpretation and report portion is reported with CPT® Code 0180T.

1. Indications

The 64-lead or greater electrocardiogram (ECG) procedure, represented by CPT® Code 0179T, is indicated for various cardiac conditions that require detailed analysis of the heart's electrical activity. The following conditions may warrant the use of this advanced ECG technique:

  • Myocardial Infarction - This condition, commonly known as a heart attack, can be diagnosed and localized with greater confidence using the extensive lead placement of a 64-lead ECG.
  • Ventricular Tachycardia - This arrhythmia, characterized by an abnormally fast heart rate originating from the ventricles, can be better assessed with the additional leads.
  • Ventricular Fibrillation - A life-threatening arrhythmia that requires immediate attention; the detailed mapping provided by a 64-lead ECG can assist in diagnosis.
  • Atrial Arrhythmias - Conditions affecting the atria, such as atrial fibrillation, can be more accurately diagnosed with the enhanced data from multiple leads.

2. Procedure

The procedure for conducting a 64-lead or greater electrocardiogram involves several key steps that ensure accurate data collection and analysis. Each step is crucial for obtaining a comprehensive understanding of the patient's cardiac health.

  • Step 1: Preparation - The patient is prepared for the procedure by ensuring that the skin is clean and free of any oils or lotions that may interfere with electrode adhesion. The physician or technician explains the procedure to the patient, addressing any questions or concerns.
  • Step 2: Lead Placement - A total of 64 or more leads are strategically placed on the patient's chest and back. The placement is determined based on the suspected cardiac condition, with leads either uniformly distributed or concentrated in specific areas over the heart to optimize data collection.
  • Step 3: Data Collection - Once the leads are in place, the ECG machine is activated to record the electrical signals from the heart. This process typically lasts several minutes, during which the machine captures the ECG signals continuously.
  • Step 4: Graphic Presentation - The recorded data is processed to create a graphic presentation in the form of a torso body map. This map visually represents the electrical activity of the heart and helps localize any areas of concern.
  • Step 5: Data Storage - The ECG signals and graphic presentation are stored on a computer disc for further analysis. This allows for detailed review and comparison with the separately reportable 12-lead ECG.
  • Step 6: Review and Analysis - The physician reviews the torso body map and the ECG tracing to identify the lead(s) that captured the most definitive data. Any abnormalities noted in the tracing are characterized for further evaluation.
  • Step 7: Reporting - Although CPT® Code 0179T is used for the tracing and graphic presentation only, the physician compiles the information from the 64-lead ECG, the separately reportable 12-lead ECG, and the graphic image to prepare a comprehensive report. This report is essential for further clinical decision-making.

3. Post-Procedure

After the completion of the 64-lead or greater ECG procedure, the patient may be monitored briefly to ensure there are no immediate adverse reactions to the electrode placement. There are typically no specific post-procedure care requirements, as the procedure is non-invasive and does not involve any recovery time. The physician will review the compiled data, including the torso body map and ECG tracing, to interpret the findings. A written report will be generated, summarizing the results and any identified abnormalities. This report may be used for further diagnostic evaluation or treatment planning, depending on the patient's clinical situation.
