The 2023 HRS/EHRA/APHRS/LAHRS expert consensus statement identifies remote monitoring as the primary follow-up mode for CIED patients. It cites measurable impact on morbidity and mortality. The same document acknowledges that rising transmission volumes create real operational challenges for device clinic staff, especially when data arrives through multiple proprietary portals with no shared infrastructure.
The remote monitoring landscape has expanded beyond pacemakers and ICDs to include Holter monitors, mobile cardiac telemetry, loop recorders, and FDA-approved wearables. Each requires separate logins and workflows. Gordon Wesley, SVP and Chief Strategy and Clinical Integration Officer at University of Chicago Medicine AdventHealth, put it this way: "We have a lot of cats in the [cardiovascular] service line, so how do you really bring those together under one platform?"
High-volume centers have moved from manual, sequential alert review toward structured triage protocols with more automation in alert prioritization and report generation. Manual processes cannot scale. Platforms that consolidate data ingestion, normalize transmission formats, and automate documentation are now a clinical and operational necessity.
Rhythm360 ingests data via API, HL7, XML, and PDF parsing through computer vision. It normalizes disparate data streams from Medtronic, Boston Scientific, Abbott, Biotronik, and others into a single, actionable dashboard, with greater than 99.9% transmissibility achieved through redundant data feeds and AI-powered gap-filling.
Alert fatigue is a patient safety problem, not a perception problem. A 2026 EHRA-presented cross-manufacturer analysis of 2,659 rhythm episodes from 1,710 patients found that 32.9% of episodes from AI-equipped implantable cardiac monitors were non-actionable, and 30.6% were indeterminate. Among devices without proprietary AI algorithms from the same manufacturers, 45.4% of episodes were non-actionable. In the same dataset, 46.8% of episodes labeled as cardiac "pause" events were false positives caused by R-wave undersensing.
Niraj Varma, MD, PhD, Professor of Medicine and Consultant Electrophysiologist at the Cleveland Clinic, stated: "False-positive alerts remain one of the biggest operational challenges in remote cardiac monitoring. Every episode flagged by an implantable cardiac monitor must be reviewed by a clinician, yet even devices equipped with manufacturer AI algorithms still generate a substantial number of non-actionable alerts."
The 2023 HRS/EHRA/APHRS/LAHRS consensus statement identifies missed alerts and unclear escalation pathways as common, preventable system failures, particularly in community and hybrid care settings.
Rhythm360 addresses this through an AI-powered triage layer that filters non-actionable transmissions and prioritizes clinically significant events such as new-onset atrial fibrillation, ventricular tachycardia, lead malfunction, and ERI/RRT indicators. Optional 24/7/365 oversight by certified cardiac technicians (CCTs) supervised by physicians adds another layer of clinical review. The result: an 80% reduction in critical alert response times.
Andrew Beaser, MD, Associate Professor of Medicine at the University of Chicago Medicine, noted: "Decision support, including AI-assisted decision support, will become increasingly important as data volumes grow." Reducing alert fatigue is only half the operational equation. The other half is making sure every clinically reviewed transmission gets billed correctly.
Billing leakage in CIED remote monitoring is systematic and preventable. Most of it traces back to a handful of device-specific CPT codes with strict documentation rules, shown below.
| CPT Code | Device Type | Component | Billing Frequency |
|---|---|---|---|
| 93294 | Single/dual-chamber pacemaker | Professional interpretation | Every 90 days (30-day minimum monitoring period) |
| 93295 | ICD (single, dual, CRT-D) | Professional interpretation | Every 90 days (30-day minimum monitoring period) |
| 93296 | Pacemaker and ICD systems | Technical component | Billed with 93294 or 93295 |
| 93297 | Implantable cardiovascular physiologic monitor system (e.g., CardioMEMS) | Technical component (with TC modifier) | Remote interrogation device evaluation (up to 30 days) |
| 93298 | Implantable loop recorder system (ILR/ICM) | Remote interrogation device evaluation (may be reported with the -TC modifier for the technical component) | Up to 30 days (2024 CMS update) |
Codes 93294 and 93295 cause the most leakage. Common errors include submitting claims for a single symptomatic transmission without satisfying the 30-day minimum monitoring period, applying monthly billing cycles to pacemakers or ICDs, which triggers denials, and failing to document the required clinician interpretation note covering device function, programmed parameters, and actionable findings.
These same 2024 CMS updates to remote monitoring codes create new revenue opportunities, but only for practices whose documentation infrastructure can meet the updated requirements.
Rhythm360 automates CPT code documentation and report generation, so billable events get captured, documented, and submitted with the required clinical interpretation. Gaurav A. Upadhyay, MD, FACC, FHRS, Director of the Pacing & Defibrillation Device Clinic at the University of Chicago Medicine, observed: "We have improved billing and accountability for our patients after the integration." Practices using Rhythm360 have increased captured revenue by as much as 300%.
Staffing shortages, workflow fragmentation, growing backlogs, and inconsistent reporting are common across device clinics. Managing data across multiple proprietary portals makes all of these problems worse. Gaurav A. Upadhyay, MD, at UCM noted: "Staffing was always an issue for our center, because our device clinic, like many other medical centers, had struggled with technician turnover and timely weekend coverage."
The build-versus-buy decision is straightforward for most practices. Building proprietary integrations with each OEM requires sustained engineering resources, ongoing maintenance, and regulatory compliance overhead that falls outside the core competency of a clinical operation.
Rhythm360's vendor-neutral architecture provides the following capabilities in a single platform:
The University of Chicago Medicine reviewed more than 73,000 reports annually through Rhythm360 in calendar year 2025, averaging more than 18,000 reports per quarter. This shows the platform can handle a high-volume clinical environment. Andrew Beaser, MD, described pre-implementation workflows as "a major challenge and incredibly difficult," and noted post-implementation: "We are able to address these issues earlier; rather than waiting for a 3-month visit, we can call patients in for evaluation."
Implementation timelines for Rhythm360, including EHR integration setup, range from a few days to a few weeks. Pricing scales on a SaaS model based on clinic size and platform usage.
The gaps described above, in triage, billing, and staffing, show up differently in every practice. Before selecting a unified monitoring platform, practice administrators and clinical leads should evaluate their current state against the following criteria:
Accurate team routing and billing depend on clean data segmentation, but most clinics lack the infrastructure to support this. That gap leads to administrative overload and compliance risks. Several operational pitfalls recur across high-volume centers during consolidation efforts.
Remote cardiac device monitoring is reimbursable under Medicare and most commercial payers through device-specific CPT codes (93294 to 93298, 93297). The supervising physician or qualified non-physician practitioner bills the professional interpretation component, while the entity operating the monitoring platform bills the technical component. Reimbursement rates vary by payer and geographic region. Practices using Rhythm360 have recovered previously uncaptured revenue through automated documentation, matching the 300% billing increase noted above. The platform itself is priced on a SaaS model that scales with clinic size and usage volume.
Rhythm360's implementation process, including EHR integration setup, typically takes from a few days to a few weeks depending on the complexity of existing systems and the number of OEM data feeds being connected. Onboarding includes patient record migration, device registration, EHR integration configuration, and staff training. RhythmScience provides structured implementation support to minimize disruption to existing clinical workflows during the transition period.
Rhythm360 is a HIPAA-compliant, cloud-based platform with a full audit trail for all transmissions, clinical actions, escalations, and patient communications. All data ingested from OEM portals and EHR systems is encrypted in transit and at rest. The platform's integrated communication hub, powered by Twilio, logs all patient interactions, including automated messages and manual phone calls, within the patient record, supporting documentation requirements for payer audits and regulatory reviews.
Rhythm360 includes a secure, HIPAA-compliant mobile application that lets electrophysiologists, cardiologists, NPs, PAs, and device technicians review transmissions, sign reports, and coordinate care from their smartphones. This matters most for on-call coverage. When a critical arrhythmia gets flagged on a weekend, the responsible clinician can review the transmission, start anticoagulation protocols, or arrange urgent evaluation without being physically present at a workstation.
Fragmented OEM portals impose a compounding cost on cardiology practices. Staff hours get lost to redundant logins, critical alerts get delayed by manual triage, and billable monitoring periods go undocumented. Consensus guidelines, real-world implementation data, and measurable outcomes at high-volume centers all support the case for consolidation.
Rhythm360 provides a vendor-neutral, AI-powered platform that unifies cardiac device health monitoring across all major manufacturers, automates alert triage and CPT code documentation, integrates bi-directionally with leading EHR systems, and delivers mobile access for on-call clinical teams. Practices that have implemented Rhythm360 have achieved the alert-response gains and revenue increases outlined above at scale.
