Foundational population health scholarship identifies four core pillars that together create a systems-level framework for improving outcomes. In cardiology, each pillar maps directly to daily clinical and operational workflows.
These four pillars provide the conceptual framework for population health management. In practice, cardiology clinics operationalize these principles through five interconnected workflow components that mirror NHS England's PHM cycle of identification, segmentation, stratification, intervention, and impact assessment.
Andrew Beaser, MD, Associate Professor of Medicine at the University of Chicago Medicine, noted: "We are able to address these issues earlier; rather than waiting for a 3-month visit, we can call patients in for evaluation." That shift from scheduled visits to continuous, data-driven intervention defines PHM in cardiology operations.
Concrete workflows show how PHM principles translate into daily clinical operations.
AI-Powered Alert Triage for CIEDs:
Automated CPT Code Capture for HF Remote Monitoring:
Gaurav A. Upadhyay, MD, at the University of Chicago Medicine, observed: "We have improved billing and accountability for our patients after the integration." UCM reviewed more than 73,000 reports annually through a unified platform in 2025, averaging more than 18,000 reports per quarter, which demonstrates the scale PHM programs can support.

Data fragmentation remains the primary operational barrier to PHM in cardiology. Practices that implant devices from multiple manufacturers such as Medtronic, Boston Scientific, Abbott, and Biotronik must log into separate, non-interoperable OEM portals to retrieve patient data. This fragmentation creates administrative overload, inconsistent alert coverage, and incomplete billing documentation.
Other platforms in the cardiac monitoring space address portions of this workflow, yet many still leave gaps between device data, clinical workflows, and billing compliance. The broader challenge centers on consolidating these elements into a single, scalable system that supports both clinical and financial goals.
Rhythm360 by RhythmScience addresses this challenge through a vendor-neutral, HIPAA-compliant, cloud-based platform that ingests and normalizes data from all major device manufacturers using API, HL7, XML, and PDF parsing via computer vision. The platform achieves greater than 99.9% data transmissibility through redundant data feeds and AI-powered extrapolation, so a server outage at any single OEM does not create a gap in patient monitoring.
Rhythm360 supports PHM workflows through three integrated layers. First, a unified dashboard consolidates CIED and RPM data across all manufacturers, which removes redundant portal logins and centralizes review. Second, AI-powered alert triage filters non-actionable transmissions and prioritizes clinically significant events, with optional 24/7/365 oversight by certified cardiac technicians. Third, bidirectional EHR integration with Epic, Cerner, Athenahealth, eClinicalWorks, Greenway Health, and others via HL7, combined with automated documentation, supports compliant billing for CPT codes including 93298, 93299, 99453, 99454, 99445, 99457, 99458, and 99470 under CMS's 2026 Final Rule. A HIPAA-compliant mobile application and integrated Twilio-powered messaging extend these capabilities to clinicians on the move.

Marcus Pritchett, Cardiac Device Specialist at Kansas City Heart Rhythm Institute, explained: "Having alert systems clear urgent versus non-urgent is the timeline difference." Rhythm360's triage architecture operationalizes that distinction at scale and supports improved billing outcomes through compliant, automated documentation.
PHM programs in cardiology rely on a multidisciplinary workforce that includes electrophysiologists, cardiologists, nurse practitioners, physician assistants, registered nurses, and certified cardiac technicians. Each role carries specific responsibilities within risk stratification and care coordination workflows.
Administrative overload from fragmented OEM portals drives burnout among device technicians and clinical staff. Clinical-grade filters that automate the triage of thousands of signals protect the workforce from burnout while ensuring patient safety. Unified platforms also reduce reliance on a single "super-user" for data retrieval, which improves business continuity and makes specialized roles more sustainable and attractive.
For practice administrators, a centralized dashboard that surfaces real-time compliance metrics, billable activity tracking, and critical alert status reduces operational complexity. Practices that implement unified monitoring report measurable improvements in staff satisfaction alongside clinical and financial outcomes.
Andrew Beaser, MD, at the University of Chicago Medicine, noted: "Decision support, including AI-assisted decision support, will become increasingly important as data volumes grow." Practices that invest in platforms automating routine triage and documentation preserve clinical staff capacity for higher-acuity decision-making.
Standard remote monitoring retrieves data from individual device transmissions and generates alerts on a per-patient basis. Population health management applies a broader framework of risk stratification, care coordination, chronic disease management, and patient engagement across an entire defined patient population at once. In cardiology, teams use aggregated CIED and RPM data to identify which patients are trending toward decompensation before a hospitalization occurs, route alerts to the appropriate care team member based on clinical priority, and document all interactions in a way that supports compliant billing. The core difference is the move from reactive, event-driven care to proactive, population-level management.
The 2026 CPT framework described earlier includes both device supply codes and time-based management codes for RPM. For CIED-specific monitoring, CPT 93298 and 93299 apply to remote interrogation of implantable cardioverter-defibrillators and pacemakers. Compliant billing requires documented patient consent, FDA-cleared devices with automated data transmission, an established patient-provider relationship, and time documentation that meets each code's threshold without double-counting time across concurrent programs such as CCM or PCM.
Device clinics often process thousands of transmissions annually, and many alerts are clinically non-relevant. AI triage systems analyze incoming transmissions against clinical logic and historical patient data to classify alerts by urgency, separating ventricular arrhythmias and lead malfunctions from routine battery status checks and connectivity notifications. In the LINK-HF2 trial of AI-enabled remote monitoring, 95% of AI-generated alerts were reviewed by clinicians within 24 hours and 26.7% led to clinical actions such as therapy adjustments, which shows that well-designed triage systems maintain clinical utility while reducing noise. Effective programs integrate AI triage into defined escalation workflows so alerts route to the appropriate care team member with documented response times, which reduces alert fatigue and the risk of missed critical events.
The financial case for unified cardiac RPM operates on three levels. First, automated CPT documentation reduces revenue leakage when billable monitoring activities go uncaptured in manual, fragmented workflows. For mature RPM programs, gross revenue per fully enrolled patient can reach $120 to $170 per month under 2026 rates across applicable codes. Second, fewer preventable hospitalizations lower total cost of care, which matters under value-based contracts. Third, operational efficiency gains from eliminating redundant portal logins and manual data transcription reduce staff overhead. Practices implementing Rhythm360 have reported up to a 300% increase in profitability through stronger CPT code capture, improved staff efficiency, and the addition of HF and HTN RPM service lines. Billing outcomes improve when documentation is automated, auditable, and aligned with CMS's 2026 compliance requirements, including the OIG's focus on complete documentation of patient education, device supply, and treatment management.
Population health management functions as the operational framework that determines whether a cardiology practice catches a Saturday morning arrhythmia before it becomes a Monday stroke, whether a heart failure patient's weight trend triggers a call before a hospitalization, and whether every billable monitoring interaction appears in a compliant, auditable record.
Evidence consistently shows that remote monitoring can reduce all-cause mortality and heart failure hospitalizations compared with standard care. The clinical benefit is clear. Realizing that benefit at scale requires a unified, vendor-neutral platform that aggregates all device data, applies AI-powered triage, and automates compliant billing documentation.
Rhythm360 delivers this infrastructure by consolidating CIED and chronic disease monitoring into a single HIPAA-compliant dashboard, integrating bidirectionally with major EHR systems, and supporting the full 2026 CPT billing framework for cardiac RPM. The University of Chicago Medicine processed more than 73,000 reports annually through Rhythm360 in 2025, with clinicians identifying more abnormalities earlier and reporting improved billing accountability.
