Official Description

Wearable electrocardiographic rhythm derived monitoring for 24 hours by continuous original waveform recording and storage without superimposition scanning utilizing a device capable of producing a full miniaturized printout; physician review and interpretation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Wearable electrocardiographic rhythm-derived monitoring, as described by CPT® Code 93233, involves the collection of electrocardiographic (ECG) data over a continuous 24-hour period. This procedure is performed using a specialized device, commonly referred to as a Holter monitor, which is worn by the patient during their normal daily activities. The device is equipped with electrodes or leads that are strategically placed on the patient's chest to capture the electrical activity of the heart. Throughout the monitoring period, the device records original ECG waveforms continuously, ensuring that all relevant heart rhythm data is collected without interruption. The recorded data is stored on a medium such as magnetic tape or a digital format, allowing for later analysis. Upon completion of the monitoring period, the patient returns the device, and the stored data is analyzed to assess various cardiac parameters, including heart rhythm and rate, ST segment analysis, heart rate variability, and T-wave alternans. A miniaturized printout of the entire recording is generated, accompanied by a microprocessor-based analysis report that includes selective sampling of rhythm strips. The physician is responsible for reviewing and interpreting this data to identify any potential heart arrhythmias. It is important to note that while CPT® Code 93233 specifically pertains to the physician's review and interpretation of the data, other related codes exist for the complete procedure, recording, and analysis components, ensuring comprehensive billing and documentation for the entire monitoring process.

1. Indications

The wearable electrocardiographic rhythm-derived monitoring procedure is indicated for various clinical scenarios where continuous heart rhythm assessment is necessary. The following conditions may warrant the use of this monitoring technique:

  • Assessment of Arrhythmias - This procedure is utilized to evaluate patients suspected of having arrhythmias, which are irregular heartbeats that can lead to serious complications.
  • Evaluation of Palpitations - Patients experiencing unexplained palpitations may undergo this monitoring to determine the underlying cause of their symptoms.
  • Monitoring of Heart Rate Variability - This procedure can be indicated for assessing heart rate variability, which is important in understanding autonomic nervous system function and overall cardiovascular health.
  • Preoperative Assessment - In some cases, this monitoring may be performed as part of a preoperative evaluation to assess cardiac risk in patients undergoing surgery.

2. Procedure

The procedure for wearable electrocardiographic rhythm-derived monitoring involves several key steps to ensure accurate data collection and analysis. The following outlines the procedural steps:

  • Step 1: Patient Preparation - The patient is prepared for the monitoring by having electrodes or leads placed on their chest. This step is crucial as it ensures that the device can accurately capture the electrical signals from the heart.
  • Step 2: Device Application - Once the electrodes are in place, the Holter monitor is attached to the patient. The patient is instructed on how to use the device, including any necessary precautions to take during the monitoring period.
  • Step 3: Continuous Monitoring - The device records the ECG continuously for a full 24 hours. During this time, the patient goes about their regular daily activities, allowing for a comprehensive assessment of their heart rhythm under normal conditions.
  • Step 4: Data Storage - The recorded ECG data is stored on a medium, such as magnetic tape or a digital format, ensuring that all information is preserved for later analysis.
  • Step 5: Device Return - After the 24-hour monitoring period, the patient returns the device to the healthcare provider for data retrieval and analysis.
  • Step 6: Data Analysis - The stored data is analyzed using a microprocessor-based system, which generates a report that includes a miniaturized printout of the ECG recordings and selective rhythm strips.
  • Step 7: Physician Review - Finally, the physician reviews and interprets the data to identify any arrhythmias or other cardiac abnormalities, providing a comprehensive assessment of the patient's heart health.

3. Post-Procedure

After the completion of the wearable electrocardiographic rhythm-derived monitoring, the patient may be provided with instructions regarding any follow-up care or additional testing that may be necessary based on the results of the monitoring. The physician will typically discuss the findings with the patient, including any identified arrhythmias or other significant cardiac events. Depending on the results, further diagnostic testing or treatment options may be recommended to address any identified issues. It is essential for the patient to maintain communication with their healthcare provider regarding any ongoing symptoms or concerns following the procedure.
