See Rhythm360 In Action For Your Clinic
Many vendors describe their product as “EHR-connected,” yet capabilities vary widely. Some platforms support true bidirectional discrete-data integration. Others only attach a PDF to the patient chart. That difference shapes daily workflow, billing performance, and clinical safety.
A PDF drop forces staff to extract and re-enter data by hand. This manual process increases transcription errors and produces unstructured information the EHR cannot query, route, or use for alerts and billing.
True bidirectional integration writes structured device data such as AF burden, ventricular rate, lead impedance, and battery status into discrete EHR fields. It also reads patient demographics, scheduling, and clinical context back into the monitoring platform.
Apply this test to every vendor you evaluate. Ask whether device interrogations populate discrete fields or only attach a document. A discrete-data workflow supports automation, reporting, and safer care.
Rhythm360 delivers this level of integration. Its bidirectional EHR connection writes structured device data directly into the chart while pulling patient context back into the monitoring workflow.
See How Bidirectional Integration Works In Your EHR
Bidirectional integration means device data flows into the EHR as discrete, queryable fields. Patient demographics, scheduling, and clinical context then flow back to the monitoring platform.
HL7 v2.x remains the workhorse messaging standard for roughly 90% of U.S. hospital interface traffic, and FHIR supports modern RESTful integrations and mobile-app data exchange. PDF-drop tools only attach documents, so the EHR cannot query or route the data.
Rhythm360 integrates with Epic, Cerner, Athenahealth, eClinicalWorks, Greenway Health, and others via HL7. Device interrogations populate discrete fields instead of static document attachments.
Vendors should clearly list the EHR systems they support and describe the integration method for each. The major cardiology platforms include Epic, Oracle Health/Cerner, athenahealth, eClinicalWorks, NextGen, and Greenway.
Each of these systems supports integration through HL7, FHIR, or SMART on FHIR. SMART on FHIR is the OAuth 2.0/OpenID Connect authorization framework that lets third-party apps run inside an EHR using standardized launch context to read or write clinical data.
Most practices implant devices from multiple manufacturers. Separate portals for Medtronic, Boston Scientific, Abbott, and Biotronik create fragmented workflows and missed transmissions.
Rhythm360 ingests and normalizes data from all major OEMs via API, HL7, XML, and PDF parsing with computer vision. Every transmission lands in one consolidated source of truth.
CIED remote monitoring billing follows two distinct cycles. Pacemakers and ICDs use a 90-day cycle with codes 93294 (pacemaker professional), 93295 (ICD professional), and 93296 (pacemaker/ICD technical).
Physiologic monitors and loop recorders use a 30-day cycle with device-specific codes. Code 93297 covers implantable cardiovascular physiologic monitors such as CardioMEMS, and 93298 covers subcutaneous cardiac rhythm monitors and ILRs. Each 30-day code is billable once per completed monitoring period and can be billed global, with modifier -26 for the professional component, or with modifier -TC for the technical component.
Billing 93298 for a defibrillator patient is denied as a device mismatch, which remains a common and preventable denial cause. Rhythm360’s automated CPT capture and documentation help practices avoid device-type mismatch denials and unbilled technical components.
Compliant remote cardiac device monitoring requires complete and separate documentation trails. A technical record supports 93296, and a separate interpretive note supports 93294 or 93295. Each claim must stand on its own documentation.
For 93297 and 93298, the record must show that a qualified professional reviewed the transmitted data and reached a clinical interpretation, including the explicit start and end dates of the 30-day period.
Rhythm360 generates audit-ready documentation at every step, which reduces the risk of denials from thin or incomplete notes.
Critical alerts arrive at all hours, so clinicians need secure access away from the workstation. A HIPAA-compliant mobile app lets providers review transmissions, sign reports, and coordinate care from any location.
This access reduces the chance that a weekend arrhythmia event goes unaddressed. As one clinician at the University of Chicago Medicine noted after implementing Rhythm360, “I am more likely to sign off on these while in meetings because I can easily access them on my phone.”
Rhythm360’s HIPAA-compliant mobile app supports this continuity of care across the entire clinical team.
Rhythm360’s onboarding process, including EHR integration, typically takes a few days to a few weeks. Custom, one-off EHR integration builds often take months and may carry a separate fee on top of the platform’s base cost.
Before signing any contract, confirm in writing whether EHR integration is included in the base cost. Also request a firm go-live date with defined milestones.
Epic, Oracle Health/Cerner, athenahealth, eClinicalWorks, and Greenway all support cardiac device monitoring integration through Rhythm360’s bidirectional EHR integration via HL7 and SMART on FHIR APIs. Integration depth varies by platform and vendor.
The most common bidirectional FHIR pattern works in three steps. The device sends data to the manufacturer’s IoT cloud. That cloud forwards the data to the hospital’s FHIR server via HTTPS POST, authenticated using SMART on FHIR with a registered backend service.
HL7 v2 remains the dominant standard for ADT and observation messaging, and FHIR enables structured, resource-based data exchange for modern integrations. The summary below shows how Rhythm360 connects to major EHR platforms and supports billing workflows.

Remote CIED monitoring billing uses two code families tied to device type. Pacemakers and ICDs follow a 90-day cycle. Code 93296 is the technical-only code for remote pacemaker and implantable defibrillator monitoring, paired with professional codes 93294 and 93295. A device clinic that owns the monitoring platform and employs the reading physician bills two codes, 93296 plus 93294 or 93295.
Physiologic monitors and loop recorders follow a 30-day cycle with device-specific codes. Code 93297 is reported once per 30-day period for implantable cardiovascular physiologic monitors, and consecutive periods must not overlap. Practices that apply a 90-day billing calendar to 93298 underbill significantly, filing four claims per year where twelve are payable.
Rhythm360’s automated CPT capture tracks device-specific billing cycles, flags missed periods, and generates the documentation required for both technical and professional components. “We have improved billing and accountability for our patients after the integration,” noted Gaurav A. Upadhyay, MD at University of Chicago Medicine following Rhythm360 implementation.
As noted in the implementation criterion above, Rhythm360’s onboarding, including EHR integration, usually completes within a few days to a few weeks. The primary variables include EHR complexity, the number of systems involved, and the responsiveness of internal IT stakeholders.
Custom, one-off builds often take months and may carry a separate fee, so practices should secure a firm go-live date and confirm whether integration is included in the base cost.
Teams should also plan for staff training and workflow validation as part of go-live. Greenway Health attributes most implementation delays to building, testing, and troubleshooting integrations between the EHR and third-party tools rather than to software installation. Selecting a vendor that builds and maintains integrations in-house reduces this risk.
This checklist extends the seven criteria above and adds one more requirement focused on interoperability standards.
Epic, Oracle Health/Cerner, athenahealth, eClinicalWorks, and Greenway all support cardiac device monitoring integration via HL7, FHIR, or SMART on FHIR. The best fit for a given practice depends on the current EHR footprint, the depth of integration the monitoring vendor supports for that system, and whether the integration supports discrete data instead of document-only workflows.
Regardless of EHR choice, practices should confirm that their monitoring platform writes discrete data into the EHR and supports the bidirectional workflows described earlier.
Rhythm360 by RhythmScience provides vendor-neutral, EHR-integrated cardiac device monitoring with automated CPT documentation and AI-powered alert triage. Practices can use the criteria and checklist in this article to evaluate any vendor, with special attention to discrete-data integration and named EHR compatibility.
“EHR-connected” tools that only drop PDFs into the chart create manual work, billing problems, and slower responses to critical alerts. True bidirectional integration, such as the model Rhythm360 delivers, writes discrete device data into the EHR, supports CPT documentation across both 90-day and 30-day billing cycles, and shortens response times for urgent events.
Rhythm360 is a vendor-neutral, AI-powered platform that unifies Medtronic, Boston Scientific, Abbott, and Biotronik device data into a single source of truth. It provides bidirectional EHR integration across Epic, Cerner, Athenahealth, eClinicalWorks, Greenway Health, and additional systems. As data volumes grow, AI-assisted decision support will become increasingly important, and Rhythm360 is built for that scale.
