Common Language Description

The CPT® Code 93298 refers to the interrogation device evaluation(s) performed remotely for a subcutaneous cardiac rhythm monitor system, which can last up to 30 days. This procedure involves a comprehensive analysis of the recorded heart rhythm data, which is crucial for assessing the functionality of the cardiac monitor. During this evaluation, a physician or another qualified healthcare professional conducts a thorough review of the data collected by the device. This includes an assessment of the device's leads, battery status, and the programmed parameters that are essential for detecting and recording rhythm events. The interrogation process allows for the examination of stored data, including any significant rhythm events that may have occurred since the last evaluation. The physician reviews heart rate and rhythm data during both patient-activated events and those automatically detected by the device. This detailed analysis is vital for identifying potential arrhythmias such as atrial fibrillation, premature atrial or ventricular contractions, supraventricular or ventricular tachycardia, and atrioventricular block. Additionally, the evaluation includes a review of rhythm alerts and recording parameters to ensure the device is functioning correctly. The total memory capacity of the device is checked, along with its ability to record the number of episodes that were either patient-activated or automatically detected. The pre- and post-episode recordings are also assessed to provide a complete picture of the patient's cardiac activity. Following the evaluation, the patient is informed of the findings, and a written report is generated to document the results of the interrogation and any necessary follow-up actions.

1. Indications

The procedure associated with CPT® Code 93298 is indicated for patients who require monitoring of their cardiac rhythm through a subcutaneous cardiac rhythm monitor system. The following conditions may warrant this evaluation:

  • Assessment of Arrhythmias Patients experiencing symptoms suggestive of arrhythmias, such as palpitations, syncope, or unexplained dizziness, may require this procedure to evaluate their heart rhythm.
  • Device Functionality Check Individuals with implanted subcutaneous cardiac monitors need regular evaluations to ensure the device is functioning correctly, including the assessment of leads and battery life.
  • Monitoring of Atrial Fibrillation Patients diagnosed with atrial fibrillation may need ongoing monitoring to assess the frequency and duration of episodes, which can be captured through this interrogation process.
  • Evaluation of Cardiac Events Patients who have experienced significant cardiac events or changes in their health status may require this procedure to analyze recorded data for any new or recurring issues.

2. Procedure

The procedure for CPT® Code 93298 involves several critical steps to ensure a comprehensive evaluation of the subcutaneous cardiac rhythm monitor system. Each step is essential for obtaining accurate data and providing a thorough analysis.

  • Remote Interrogation The first step involves the remote interrogation of the cardiac rhythm monitor. This is done by accessing the device's stored data, which includes heart rhythm recordings over the monitoring period. The healthcare professional initiates the interrogation process, allowing for the retrieval of critical information regarding the patient's cardiac activity.
  • Data Analysis Following the interrogation, the physician or qualified healthcare professional conducts a detailed analysis of the recorded heart rhythm data. This includes reviewing the device's functionality, such as the integrity of the leads and the status of the battery. The analysis also encompasses the programmed parameters that dictate how the device detects and records rhythm events.
  • Review of Stored Events The next step involves a thorough review of any stored events within the device. The healthcare professional compares these events with previous data acquisitions to identify any changes or trends in the patient's heart rhythm. This comparison is crucial for understanding the patient's condition over time.
  • Assessment of Rhythm Episodes The physician reviews heart rate and rhythm data during both patient-activated and automatically detected episodes. This assessment is vital for identifying any arrhythmias or irregularities that may require further intervention.
  • Evaluation of Alerts and Recording Parameters The healthcare professional also reviews any rhythm alerts generated by the device, along with the recording parameters. This evaluation ensures that the device is appropriately sensing and capturing cardiac rhythms, which is essential for accurate monitoring.
  • Documentation of Findings Finally, the findings from the interrogation and analysis are documented in a written report. The patient is informed of the results, and any necessary follow-up actions are discussed. This documentation serves as a critical record for ongoing patient care and management.

3. Post-Procedure

After the completion of the interrogation device evaluation, the patient may be advised on any necessary follow-up appointments or additional monitoring that may be required based on the findings. The physician will discuss the results of the evaluation with the patient, including any identified issues or concerns regarding their cardiac rhythm. If any abnormalities are detected, further diagnostic testing or adjustments to the monitoring device may be recommended. The patient should also be informed about the importance of reporting any new symptoms or changes in their condition to their healthcare provider promptly. Overall, the post-procedure care focuses on ensuring the patient's ongoing health and the effective management of their cardiac condition.

TC Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles
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.
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
GW Service not related to the hospice patient's terminal condition
GZ Item or service expected to be denied as not reasonable and necessary
CR Catastrophe/disaster related
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
GV Attending physician not employed or paid under arrangement by the patient's hospice provider
XE Separate encounter, a service that is distinct because it occurred during a separate encounter
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.
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).
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).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.)
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.
