Cardiology practices that implant devices from more than one manufacturer face an immediate operational problem: each OEM uses a separate portal with its own login, nomenclature, and data format. Clinicians must pull together data from multiple settings and multiple vendors, while traditional EHRs are not well suited to managing CIED data. Fragmented portals lead to disjointed workflows, duplicate tests, delayed diagnoses, and avoidable adverse events.
The financial impact is substantial. Without integrated CIED data, charge capture gaps hide in mismatched encounter IDs, which produces lost revenue opportunities. At the same time, the Heart Failure Society of America and the American Association of Heart Failure Nurses 2026 joint scientific statement cites lack of interoperability as a primary barrier to integrated health technologies in heart failure management. That barrier disrupts clinician workflow and weakens patient engagement.
Three monitoring modalities dominate the 2026 landscape, and each serves a different role.
CardioMEMS is an FDA-approved implantable pulmonary artery pressure sensor. The 2026 COAST study of 304 NYHA class III patients across 37 centers evaluated heart failure hospitalization rates one year before and after implantation. CardioMEMS excels at hemodynamic surveillance for a specific, high-acuity population.
Multi-parameter RPM uses external sensors such as cellular weight scales, blood pressure cuffs, and pulse oximeters to track daily physiologic readings. Cellular-connected dedicated devices are preferred for heart failure and older populations because they bypass Wi-Fi and Bluetooth pairing failures, which improves adherence to CPT billing thresholds.
Unified platforms bring both modalities together and add CIED transmissions in a single workspace. A 2026 meta-analysis by Scholte et al. of 79 randomized trials including 31,669 heart failure patients confirmed that remote monitoring reduces total HF hospitalizations, first HF hospitalizations, and all-cause mortality across modalities, with consistent benefits regardless of patient age, sex, LVEF, NYHA class, or geographic region. For practices that manage mixed CIED and HF populations, a unified platform offers the only architecture that scales across all three modality types without multiplying administrative overhead.
Rhythm360 ingests data through APIs, HL7 feeds, XML files, and unstructured PDFs parsed with computer vision and AI-powered normalization. Device transmissions from pacemakers, ICDs, implantable loop recorders, CRT devices, and CardioMEMS sensors sit alongside daily weight and blood pressure readings from cellular RPM kits, all within a single patient record.
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 volume demonstrates the platform’s ability to support high-volume mixed populations without loss of data fidelity. As Andrew Beaser, MD, Associate Professor of Medicine at UCM, noted, “We are able to address these issues earlier; rather than waiting for a 3-month visit, we can call patients in for evaluation.”
Kubica et al. (Cardiology Journal 2026) describe next-generation remote monitoring as AI systems that analyze longitudinal physiological and behavioral signals to generate context-aware alerts, actionable recommendations, and earlier detection of decompensation while reducing clinical workload. Rhythm360 applies this model through an AI alert triage layer that filters non-actionable transmissions and surfaces only clinically significant events.
This approach produces measurable gains. Rhythm360 reduces critical alert response times by up to 80%. In a Saturday-morning transmission that flags new-onset atrial fibrillation, the AI triage engine elevates the alert immediately, a clinician reviews it in the mobile app, and by Saturday afternoon the patient receives anticoagulation therapy. Without a unified platform, that intervention might wait until Monday or never occur. Andrew Beaser, MD, at UCM, observed, “Decision support, including AI-assisted decision support, will become increasingly important as data volumes grow.”
In the LINK-HF2 trial, 95% of AI-generated remote-monitoring alerts were reviewed by clinicians within 24 hours and 26.7% led to clinical action such as therapy adjustment. These results show how AI triage converts raw alert volume into focused, actionable care.
The 2026 CPT code landscape for remote heart failure monitoring is more granular than in prior years. Key codes include:
Rhythm360 automates CPT code capture and generates audit-ready documentation aligned to these requirements, which helps practices recover previously lost revenue. Practices using the platform have achieved up to a 300% increase in revenue through optimized CPT code capture, improved staff efficiency, and new RPM service lines for HF and hypertension. Gaurav A. Upadhyay, MD, at UCM, noted, “We have improved billing and accountability for our patients after the integration.”
Payer policy in 2026 varies by plan. Aetna’s April 2026 policy limits RPM coverage to heart failure, hypertension, and diabetes, and covers CPT 99453, 99454, 99457, and 99458 but not the new short-cycle codes. Anthem commercial plans support the new 2026 short-cycle codes CPT 99445 and 99470. Rhythm360’s billing documentation layer supports documentation standards across this payer mix.
Rhythm360 supports bi-directional integration with Epic, Cerner, Athenahealth, eClinicalWorks, Greenway Health, and additional systems via HL7. In 2026, RPM platforms connect to EHRs using HL7 and FHIR standards so that RPM data flows directly into the patient record and remains visible to specialists, primary care providers, and emergency teams.
Onboarding, including EHR integration setup, typically takes a few days to a few weeks. Interoperability between AI remote-monitoring outputs and existing EHRs can be achieved through HL7-FHIR, DICOM-SR, and SMART-on-FHIR interfaces. Rhythm360’s implementation team manages the technical configuration, which limits disruption to clinical operations during the transition.
Cellular-connected monitoring devices now represent the most reliable option for closing the adherence gap in remote patient monitoring. These devices transmit consistently without relying on patient-managed Wi-Fi or smartphone pairing. For heart failure populations that are often elderly, managing multiple comorbidities, and less technically proficient, Bluetooth-dependent devices introduce a significant compliance risk.
Bluetooth pairing loss after phone updates, Wi-Fi hubs going offline, forgotten app steps, and complex setup for elderly patients all contribute to missed alerts and incomplete monitoring data. Rhythm360’s cellular RPM kits reach greater than 99.9% transmissibility through redundant data feeds, computer vision, and AI-powered extrapolation. Bluetooth-dependent configurations cannot consistently match this reliability at scale.
Rhythm360’s HIPAA-compliant mobile application allows electrophysiologists, cardiologists, nurse practitioners, and device technicians to review transmissions, sign reports, and coordinate care from any location. The Saturday-morning AFib scenario described earlier only becomes actionable when the on-call clinician can access and act on the alert without returning to a workstation.
Among patients with implantable devices, use of a dedicated smartphone application was associated with high uptake and sustained adherence, especially in centers supported by structured remote monitoring teams. The mobile interface presents the same prioritized alert queue available on the desktop dashboard and records a full audit trail of every review and action.
Rhythm360 follows a streamlined implementation process that limits disruption. The typical onboarding sequence includes:
UCM’s implementation of Rhythm360 enabled clinicians to review more transmissions daily and identify more abnormalities. The program scaled to handle the volume described earlier without requiring proportional increases in staffing. SaaS-based pricing scales with clinic size and platform usage, which keeps the investment model accessible for solo practices and large health systems.

CIED remote monitoring covers interrogation and interpretation of implanted devices such as pacemakers, ICDs, implantable loop recorders, and CRT devices using manufacturer-specific transmission protocols. Heart failure RPM uses external physiologic sensors such as cellular weight scales and blood pressure cuffs to track daily fluid status and hemodynamic trends. These two service lines have historically operated in separate workflows with separate billing codes and separate portals. Rhythm360 manages both within a single platform through distinct but integrated service lines, Rhythm-CIED and HF/HTN RPM, so a device technician and a care manager can work from the same dashboard without duplicating data entry or toggling between systems.
Legacy systems generate high volumes of alerts using static thresholds, and many alerts are non-actionable. AI triage replaces static rules with trajectory analysis that evaluates longitudinal physiological patterns and assigns severity levels based on clinical significance. In Rhythm360, alerts appear in tiered queues for critical events that require immediate action, events that require follow-up within 24 hours, and informational notifications, with per-patient personalized thresholds. Optional 24/7/365 oversight by certified cardiac technicians adds a human review layer for the highest-severity events. This structure reduces low-priority interruptions while ensuring that events such as new-onset AFib, ventricular tachycardia, or significant weight gain surface immediately to the appropriate clinician.
The 2026 CPT code set for remote heart failure monitoring spans two families. For CIED monitoring, the relevant codes are 93294 and 93295 for pacemaker and ICD professional interpretation, 93296 for the technical component, and 93297 and 93298 for implantable loop recorder monitoring. For physiologic RPM, the core codes are 99453 for initial setup, 99445 for 2–15 days of device supply (new in 2026), 99454 for 16 or more days of device supply, 99470 for 10–19 minutes of management time (new in 2026), 99457 for 20 or more minutes of management time, and 99458 as an add-on for additional time increments. Rhythm360 automates tracking of monitoring days, clinician time, and billable events, and generates documentation structured to satisfy audit requirements across this code set. Payer policies vary, as Aetna covers the traditional RPM codes for heart failure but has not adopted the new short-cycle codes, while Anthem supports 99445 and 99470 for automatically transmitted data from FDA-cleared devices, and Rhythm360’s documentation layer accommodates these differences.
Rhythm360 supports bi-directional integration with Epic, Cerner, Athenahealth, eClinicalWorks, Greenway Health, and additional systems via HL7 and FHIR. The full onboarding process, which includes OEM portal credentialing, EHR integration configuration, staff training, and patient enrollment, typically takes a few days to a few weeks depending on practice size and EHR complexity. The implementation team manages the technical configuration on the practice’s behalf, which reduces the burden on internal IT resources. Because Rhythm360 uses a SaaS delivery model, practices avoid on-premise infrastructure installation and benefit from a shorter deployment timeline than legacy on-premise systems.
Rhythm360 addresses both failure modes through a redundant data feed architecture. If an OEM server experiences downtime, the platform’s fail-safe layer maintains data continuity by cross-referencing alternative data sources and applying AI-powered extrapolation to fill gaps. For patient-side connectivity, cellular RPM kits transmit over embedded LTE modules without requiring Wi-Fi, smartphone pairing, or app interaction, which removes the most common causes of missed transmissions in Bluetooth-dependent configurations. The combined result is greater than 99.9% transmissibility across the patient population, a reliability level that protects CPT billing eligibility and helps ensure that critical physiologic changes are not missed due to technical failures.
Fragmented OEM portals, manual data reconciliation, and disconnected billing workflows create measurable costs for cardiology practices, including missed critical events, alert fatigue, revenue leakage, and staff burnout. Rhythm360 addresses each of these problems through a single vendor-neutral platform that consolidates CIED and HF physiologic data, applies AI-powered alert triage, automates CPT billing documentation, and integrates bi-directionally with major EHR systems, all with greater than 99.9% data transmissibility and a mobile-first design for on-call clinicians.
The 2026 evidence base consistently supports unified remote monitoring. A meta-analysis of 79 randomized trials shows that remote monitoring reduces HF hospitalizations and all-cause mortality across patient populations. University of Chicago Medicine processed more than 73,000 annual reports through Rhythm360 with earlier interventions and improved billing accountability. Practices using the platform have achieved the revenue and response-time improvements detailed above.
