Summary & Overview
CPT 0579T: Remote ICD Interrogation by Technician, Up to 90 Days
CPT code 0579T denotes a technician-performed remote interrogation and evaluation of an implantable cardioverter–defibrillator (ICD) system covering a monitoring period of up to 90 days. As remote cardiac device management expands nationally, this CPT code captures a distinct technical service: acquiring transmissions, reviewing data, offering technical support, and distributing results without direct physician interpretation. The code is relevant for health systems, device monitoring centers, and payers managing the shift toward telemonitoring.
Key payers in coverage discussions include Aetna, Blue Cross Blue Shield plans, Cigna, UnitedHealthcare, and Medicare. Readers will find an overview of typical sites of service, the clinical context for ICD remote monitoring, and the operational scope of technician-led evaluations. The publication provides benchmarks for service definitions, common modifiers associated with remote services, and considerations for billing workflows and documentation. It highlights how this service fits into broader remote cardiac monitoring programs and identifies where input is limited by missing data.
This national summary is intended for billing managers, compliance officers, clinical program leads, and policy analysts seeking a concise briefing on CPT code 0579T, its purpose, and implications for remote cardiac device services.
Billing Code Overview
CPT code 0579T describes a technician-performed remote interrogation device evaluation of an implantable cardioverter–defibrillator (ICD) system for a period up to 90 days. The technician acquires transmitted data from the ICD, receives and reviews the transmissions, provides technical support, and distributes the results.
Service Type: Remote device interrogation and technical data management
Typical Site of Service: Remote/telemetry services (off-site), device monitoring centers, or clinic-based remote monitoring programs
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with ischemic cardiomyopathy and a history of ventricular tachycardia has an implantable cardioverter–defibrillator (ICD) placed for primary prevention. The device is configured for remote monitoring. Over a 90-day period following implantation or after a device reprogramming event, a trained technician performs remote interrogation device evaluation of the ICD system. The technician acquires transmitted telemetry, reviews device diagnostics for arrhythmia episodes, battery status, lead integrity, and therapy delivery logs, provides technical support to the patient and clinic staff (for example, troubleshooting connectivity or instructing the patient on transmission procedures), and distributes summarized results to the supervising physician and clinic team.
Clinical workflow:
-
The patient’s ICD initiates scheduled or patient-triggered remote transmissions to the device vendor or clinic remote monitoring platform.
-
A technician receives and aggregates transmissions over the monitoring window (up to 90 days), performs technical analysis of stored events and device parameters, and documents findings in the device report.
-
The technician escalates clinically significant events (appropriate/inappropriate shocks, sustained VT/VF, lead alerts, significant battery depletion) to the supervising electrophysiologist for interpretation and clinical decision-making.
-
The technician provides technical support to ensure continued connectivity, educates the patient on transmission steps, and distributes the final report to the cardiology team and primary provider for follow-up.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | When documentation supports substantially greater effort/technical work beyond typical remote device evaluation (rare for technician-based remote monitoring) |
51 | Multiple procedures | When billed on the same date as other distinct procedures requiring bundling rules (use per payer guidelines) |
52 | Reduced services | When the remote evaluation was partially completed or limited by technical failure |
53 | Discontinued procedure | When the remote interrogation process was started but discontinued due to patient or technical factors |
54 | Surgical care only | When a different practitioner bills postoperative management; rarely applicable for device interrogation |
55 | Postoperative management only | When another practitioner billed the procedural component and the remote monitoring is only postoperative follow-up |
62 | Two surgeons | If two qualified practitioners share responsibility for an associated procedure (uncommon for remote interrogation) |
78 | Return to OR for related procedure by same physician | When a related return procedure occurs after the monitored period |
80 | Assistant surgeon | If an assistant surgeon participates in a related operative procedure tied to the device |
82 | Assistant surgeon (when qualified resident not available) | Similar to 80 when applicable |
QK | Locum tenens - primary physician | When a locum tenens physician is the supervising physician for the remote evaluations |
QX | Certified nurse-midwife or other nonphysician practitioner billing under modifier | When an auxiliary qualified practitioner performs components under supervision |
QY | Attending physician not physically present | When the supervising physician is not physically present but provides oversight for the remote evaluations |
SH | Speech-language pathology service (not applicable generally) | Listed when a rarely used modifier applies; typically not used for this procedure |

I50.22 | Chronic systolic (congestive) heart failure | Patients with reduced ejection fraction commonly receive ICDs for prevention of sudden cardiac death; remote monitoring assesses device therapies and cardiac status |
I47.2 | Ventricular tachycardia | Primary arrhythmic indication for ICD implantation and triggers for remote transmission of arrhythmia episodes |
I46.9 | Cardiac arrest, cause unspecified | Post-arrest patients with ICDs require close monitoring for recurrent malignant arrhythmias via remote interrogation |
