Official Description

External electrocardiographic recording for more than 48 hours up to 21 days by continuous rhythm recording and storage; review and interpretation

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

External electrocardiographic recording for more than 48 hours up to 21 days by continuous rhythm recording and storage, as described by CPT® Code 0298T, refers to a specialized procedure that allows for the long-term monitoring of a patient's heart rhythm. This procedure is particularly useful for detecting arrhythmias or other cardiac abnormalities that may not be evident during a standard electrocardiogram (ECG) performed in a clinical setting. The recording is conducted using a compact, lightweight, and waterproof device that the patient wears on the upper left chest, enabling them to go about their daily activities without interruption. The device is designed to continuously record and store the heart's electrical activity over an extended period, ranging from more than 48 hours to a maximum of 21 days. During this time, the patient is instructed on how to properly use and care for the device to ensure accurate data collection. Once the monitoring period is complete, the patient returns the device to the healthcare facility, where the recorded data is downloaded for analysis. A computerized analysis is performed, and a report is generated, which is then reviewed by a physician or qualified healthcare professional. This professional provides a written interpretation of the findings, which is crucial for diagnosing potential cardiac issues. It is important to note that this code specifically pertains to the review and interpretation of the ECG data, distinguishing it from other related codes that cover different aspects of the procedure, such as the initial recording or the scanning analysis.

1. Indications

External electrocardiographic recording for more than 48 hours up to 21 days is indicated for patients who exhibit symptoms or conditions that may suggest the presence of arrhythmias or other cardiac abnormalities. The following are specific indications for this procedure:

  • Palpitations: Patients experiencing sensations of rapid, fluttering, or pounding heartbeats may require long-term monitoring to identify any underlying arrhythmias.
  • Syncope: Individuals who have experienced unexplained fainting or loss of consciousness may benefit from this procedure to determine if arrhythmias are the cause.
  • Dizziness or Lightheadedness: Patients reporting episodes of dizziness or lightheadedness may need continuous ECG monitoring to assess their heart rhythm during these episodes.
  • Post-myocardial Infarction: Patients recovering from a heart attack may require monitoring to detect any potential arrhythmias that could complicate their recovery.
  • Evaluation of Cardiac Symptoms: Patients with unexplained chest pain or other cardiac symptoms may be evaluated through long-term ECG monitoring to identify any transient arrhythmias.

2. Procedure

The procedure for external electrocardiographic recording involves several key steps to ensure accurate data collection and analysis. The following outlines the procedural steps:

  • Step 1: Device Preparation and Placement - The healthcare professional prepares the external ECG recording device, which includes both the electrodes and the recording unit. The device is then placed on the upper aspect of the patient's left chest, ensuring proper contact with the skin for optimal signal capture. The device is tested to confirm functionality before proceeding.
  • Step 2: Initial Recording - An initial ECG recording is obtained to establish a baseline rhythm. This step is crucial for identifying any pre-existing conditions that may affect the interpretation of the long-term data.
  • Step 3: Patient Instruction - The patient is instructed on the proper use and care of the recording device. This includes guidance on how to wear the device, what activities to avoid, and how to maintain the device's functionality during the monitoring period.
  • Step 4: Continuous Monitoring - The device is activated, and it continuously records the patient's ECG rhythm for a period exceeding 48 hours, up to a maximum of 21 days. This allows for comprehensive monitoring of the heart's electrical activity during the patient's normal daily activities.
  • Step 5: Device Return and Data Download - After the monitoring period concludes, the patient returns the device to the healthcare facility. The recorded data is then downloaded from the device for further analysis.
  • Step 6: Data Analysis and Interpretation - A computerized analysis of the ECG data is performed, generating a report that summarizes the findings. A physician or qualified healthcare professional reviews this data and provides a written interpretation, which is essential for diagnosing any potential cardiac issues.

3. Post-Procedure

Post-procedure care for patients who have undergone external electrocardiographic recording primarily involves the review of the generated report and the interpretation of findings by a physician or qualified healthcare professional. Patients may be advised on follow-up appointments to discuss the results and any necessary further evaluations or treatments based on the findings. Additionally, if any significant arrhythmias or abnormalities are detected, the healthcare provider may recommend further diagnostic testing or interventions to address the identified issues. It is important for patients to understand the significance of the results and to adhere to any follow-up care instructions provided by their healthcare team.
