Remote patient monitoring for cardiac conditions now falls into two clear categories. RPM tracks physiological data such as heart rate, weight, blood pressure, and oxygen saturation from FDA-cleared devices. Remote Therapeutic Monitoring (RTM) focuses on non-physiological data such as medication adherence and functional status. CIED monitoring centers on continuous surveillance of implantable devices including pacemakers, ICDs, implantable loop recorders, and subcutaneous cardiac rhythm monitors.
Revenue loss usually stems from three issues. Data sits in separate OEM portals like Medtronic, Abbott, and Boston Scientific. Staff rely on manual workflows that miss transmission thresholds. Documentation often fails to meet audit expectations. These gaps hit hardest for patients with atrial fibrillation, ventricular tachycardia, and heart failure who need consistent monitoring for both clinical outcomes and accurate billing.
Effective heart rhythm monitoring reimbursement strategies prevent claim denials, cut administrative overhead, and support scalable chronic disease programs. Financial gains extend beyond single CPT codes. Practices strengthen care coordination and improve outcomes through earlier, data-driven interventions.
CPT Code | Description | Reimbursement Rate | Key Requirements |
93298 | Subcutaneous cardiac rhythm monitor evaluation | ~$28 | 30-day analysis period |
99454 | RPM device supply 16-30 days | ~$50 | 16+ days transmission |
99445 | RPM device supply 2-15 days | ~$50 | 2-15 days transmission |
99457 | Treatment management 20+ minutes | ~$62 | Interactive communication |
Start by using a vendor-neutral platform that automatically ingests data from all major device manufacturers through API connections, HL7 integration, and computer vision parsing of PDF reports. This single source of truth removes the need for staff to log in to multiple portals. It also reduces transcription errors that undermine billing accuracy and audit readiness.
AI-driven systems should track daily transmission patterns and flag patients who approach threshold requirements. The 2026 updates allow billing CPT 99445 for patients with 2-15 days of data transmission. Practices can now capture revenue even when patients do not reach the traditional 16-day requirement for CPT 99454.
Automated reporting tools need to generate a clear record for every billable service. Each record should include exact transmission day counts, patient interaction logs, and the clinical reasoning behind decisions. Documentation must align with CMS requirements and support a strong audit defense without extra manual work.
Bi-directional integration with Epic, Cerner, or other EHR systems keeps billing workflows smooth and accurate. Integration supports clean charge capture, reduces manual data entry, and preserves a complete audit trail for monitoring activities and clinical interventions.
Intelligent alert systems should highlight patients who truly need clinical intervention and automatically log time spent on treatment management. CPT 99457 requires at least 20 minutes of clinical staff time with patient interaction. Reliable time tracking protects reimbursement and keeps staff focused on the highest-risk patients.

Workflow Aspect | Manual/Legacy Systems | Rhythm360 Platform | Key Benefit |
Data Consolidation | Multiple OEM portal logins | Single unified dashboard | 80% time reduction |
Alert Response | Manual triage and documentation | AI-powered prioritization | Faster critical interventions |
Billing Capture | Manual threshold tracking | Automated CPT compliance | 300% revenue increase |
Revenue Impact | Frequent claim denials | Audit-proof documentation | Maximized reimbursement |
Strong reimbursement performance depends on avoiding common pitfalls and following proven implementation practices. AI-based extrapolation can help address minor data gaps while preserving clinical accuracy and billing compliance. Intelligent triage rules reduce alert fatigue by surfacing clinically meaningful events and suppressing routine noise.
Compliance requires precise documentation of transmission days, patient interaction minutes, and clinical decision rationale. CPT 99454 requires device supply with daily recordings for 16 or more days of data transmission. CPT 99457 demands accurate time tracking for treatment management activities.
Track success with clear metrics such as faster response times for critical alerts, a higher percentage of billable encounters, and measurable ROI from improved revenue capture. Ongoing audit preparation should include complete documentation trails and regular reviews to confirm alignment with current CMS guidelines and local coverage determinations.

CPT 99454 covers the supply of remote monitoring devices and data transmission services. It requires at least 16 days of physiological data transmission within a 30-day period and is billed once per patient per 30-day cycle, regardless of the number of devices. CPT 99457 represents treatment management services and requires at least 20 minutes of clinical staff or physician time with interactive patient communication during a calendar month. These codes work together, with 99454 covering device and data services and 99457 covering clinical management time.
RPM focuses on physiological monitoring such as heart rate, weight, oxygen saturation, and blood pressure using FDA-cleared devices that transmit data automatically. RTM tracks non-physiological factors including medication adherence, functional status, and therapy response. For cardiology practices, RPM usually plays the central role for CIED monitoring and chronic disease management, while RTM supports medication and therapy adherence programs. Each service uses different CPT codes and billing rules, and RPM often provides higher reimbursement for physiological monitoring.
CPT 33285 covers insertion of a subcutaneous cardiac rhythm monitor and typically pairs with ongoing monitoring codes such as CPT 93298 for remote interrogation and evaluation. Monitoring services require 30-day analysis periods and create separate billable events from the initial insertion. Practices must document rhythm analysis, clinical interpretation, and any interventions that result from monitoring data to support reimbursement.
Common ICD-10 codes for remote cardiac rhythm monitoring include I48 for atrial fibrillation, I47 for ventricular tachycardia, I50 for heart failure, and I10 for hypertension. These codes must show medical necessity for remote monitoring and support the clinical rationale for ongoing surveillance. Accurate ICD-10 coding improves claim approval rates and strengthens the clinical context for monitoring, which is critical for audits and coverage determinations.
New 2026 rules introduce CPT 99445 for patients with 2-15 days of data transmission. Practices no longer lose all RPM revenue when patients fall short of 16 days. CPT 99454 still applies to patients with 16-30 days of transmission. Practices cannot bill both codes for the same patient in the same 30-day period, so teams must track transmission patterns closely and choose the appropriate code for each cycle.
The 2026 environment for heart rhythm monitoring reimbursement offers major upside for practices that adopt automated, vendor-neutral solutions. Platforms that consolidate OEM data, track thresholds, and create audit-ready documentation help practices recover lost revenue and support better patient outcomes.
Advanced strategies include expanding beyond CIED monitoring to structured heart failure and hypertension programs. Practices can use the full RPM code set to build multi-condition monitoring that supports both clinical quality and financial performance.
