Official Description

External electrocardiographic recording for more than 48 hours up to 7 days by continuous rhythm recording and storage; includes recording, scanning analysis with report, review and interpretation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

External electrocardiographic recording for more than 48 hours up to 7 days, as described by CPT® Code 93241, involves the use of a continuous rhythm recording device that captures the electrical activity of the heart over an extended period. This procedure is designed to monitor the heart's rhythm while the patient engages in their normal daily activities, providing valuable data that may not be captured during a standard, shorter ECG test. The recording device is typically a compact and lightweight unit that includes both electrodes and the recording mechanism, allowing for ease of use and comfort. It is waterproof, enabling the patient to wear it continuously without interruption for a duration that can extend from more than 48 hours to a maximum of 7 days. During the procedure, the device is affixed to the upper left chest of the patient, and an initial test recording is performed to ensure proper functionality. Patients receive instructions on how to care for and operate the device effectively. Once activated, the device continuously records and stores the ECG rhythm data. After the monitoring period concludes, the patient returns the device to the healthcare facility, where the recorded data is downloaded for further analysis. A computerized analysis is conducted, and a comprehensive report is generated. This report includes a review and interpretation of the ECG data by a physician or other qualified healthcare professional, ensuring that the findings are accurately assessed and documented. The complete procedure, encompassing rhythm recording, storage, scanning analysis, and professional interpretation, is reported using CPT® Code 93241.

1. Indications

The external electrocardiographic recording procedure is indicated for various clinical scenarios where continuous monitoring of the heart's rhythm is necessary. The following conditions may warrant this procedure:

  • Arrhythmias Patients exhibiting symptoms of irregular heartbeats or palpitations may require long-term monitoring to identify the nature and frequency of these events.
  • Unexplained Syncope Individuals who experience unexplained fainting episodes may benefit from extended ECG monitoring to determine if arrhythmias are the underlying cause.
  • Assessment of Cardiac Symptoms Patients presenting with symptoms such as chest pain, shortness of breath, or fatigue may need continuous rhythm recording to evaluate potential cardiac issues.
  • Post-Myocardial Infarction Monitoring Following a heart attack, patients may require ongoing monitoring to assess heart function and detect any arrhythmias that could arise during recovery.

2. Procedure

The procedure for external electrocardiographic recording involves several key steps to ensure accurate and effective monitoring of the patient's heart rhythm:

  • Device Preparation The healthcare provider prepares the external ECG recording device, which includes both the electrodes and the recording unit. The device is designed to be lightweight and waterproof, allowing for continuous wear.
  • Placement of the Device The device is placed on the upper aspect of the patient's left chest. Proper placement is crucial for accurate data collection, and the provider may perform an initial test recording to confirm functionality.
  • Patient Instruction The patient is instructed on how to use and care for the recording device. This includes guidance on how to activate the device and what activities to avoid during the monitoring period.
  • Continuous Recording Once activated, the device continuously records the ECG rhythm for a period exceeding 48 hours, up to a maximum of 7 days. This allows for comprehensive monitoring during the patient's normal daily activities.
  • Device Return and Data Download After the monitoring period, the patient returns the device to the healthcare facility. The recorded data is then downloaded for analysis.
  • Data Analysis and Reporting A computerized analysis of the ECG data is performed, followed by a review and interpretation by a physician or other qualified healthcare professional. A detailed report is generated, summarizing the findings.

3. Post-Procedure

After the external electrocardiographic recording procedure, the patient may be advised on any necessary follow-up appointments to discuss the results of the ECG analysis. The physician will review the report generated from the data analysis and may recommend further diagnostic testing or treatment based on the findings. Patients should be informed about any symptoms to monitor and when to seek medical attention. Overall, the procedure is designed to provide valuable insights into the patient's cardiac health, aiding in the diagnosis and management of potential heart conditions.

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).
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.
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).
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
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.)
93 Synchronous telemedicine service rendered via telephone or other real-time interactive audio-only telecommunications system : synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located away at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that is sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction.
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
