Continuous Glucose Monitoring
Abbott's FreeStyle Libre 3 Plus — the smallest iCGM sensor at just 1 gram — delivers real-time glucose readings every minute with up to 15-day sensor wear. Integrated with CCN Health via LibreView cloud API and the LibreLinkUp caregiver ecosystem.
How It Works
Easy 1-2-3 Setup
Apply the sensor, sync via Bluetooth, and let LibreView deliver data to the clinical platform.
Sensor Measurement
A small subcutaneous filament measures interstitial glucose levels continuously, generating a new reading every minute — 1,440 data points per day.
Bluetooth Relay
The sensor transmits readings via Bluetooth to the FreeStyle Libre app on the patient’s smartphone, which syncs to Abbott’s LibreView cloud. LibreLinkUp shares data with up to 20 caregivers in real time.
LibreView Cloud Integration
CCN Health pulls glucose data from LibreView’s cloud API — 1,440 data points per day with trend direction, time-in-range, and ambulatory glucose profile.
Clinical Processing
CCN Health processes glucose trends, calculates time-in-range metrics, generates alerts for hypo/hyperglycemia, and posts data to the patient’s EHR.
Live Data
Continuous Glucose Stream.
Every minute, the FreeStyle Libre sensor captures a new glucose reading and streams it to the CCN Health platform via LibreView. Clinicians see real-time trends, time-in-range analytics, and configurable alerts without waiting for a patient office visit.

Why FreeStyle Libre CGM
Clinical Evidence
Proven outcomes, published data.
Published trials demonstrate measurable outcomes with FreeStyle Libre. The IMPACT trial showed 38% less hypoglycemia in Type 1 diabetes. The FreeDM2 trial showed 0.6% greater A1c reduction in Type 2. The RELIEF study linked Libre use to 67% fewer diabetes-related hospitalizations across 74,000+ patients.

FAQ
Frequently Asked Questions
Common questions about FreeStyle Libre CGM for RPM programs.
Yes. FreeStyle Libre 3 Plus and Libre 2 Plus are FDA iCGM-cleared devices that qualify for RPM billing under CPT 99454. The Libre 3 Plus generates 1,440 glucose readings per day (every 1 minute) with up to 15-day sensor wear, flowing to the CCN Health platform via Abbott's LibreView cloud API.
The Libre sensor transmits glucose readings via Bluetooth to the FreeStyle Libre app on the patient's smartphone. The app syncs to Abbott's LibreView cloud platform (ISO 27001 certified), and CCN Health pulls data from the LibreView API. LibreLinkUp enables up to 20 caregivers to monitor glucose remotely. LibreView also integrates directly with Epic EHR via the Aura platform.
Both offer up to 15-day sensor wear and are AID-compatible. Libre 3 Plus is the smallest iCGM sensor (1 gram, 21mm diameter) with 7.9% MARD and real-time BLE streaming every minute — no scanning required. Libre 2 Plus is larger (~5g, 35mm) with 8.2% MARD and uses scan-based NFC readings with optional BLE alerts. Both are cleared for age 2+.
Both are FDA iCGM-cleared CGMs that qualify for RPM billing. FreeStyle Libre 3 Plus reads every 1 minute (vs. Dexcom's 5 minutes), offers the smallest sensor at 1 gram (vs. Dexcom G7's larger form factor), and costs roughly 80% less at retail. Both now offer up to 15-day wear. Libre integrates via LibreView; Dexcom via Clarity. Dexcom has stronger water resistance (IP68 vs. IP27) and more established AID pump partnerships.
Yes. FreeStyle Libre sensors require a compatible smartphone running the FreeStyle Libre app for BLE data relay and LibreView cloud sync. The LibreLinkUp companion app allows caregivers to view glucose data remotely. For patients without smartphones, CCN Health offers standalone cellular glucose meters as an alternative RPM option.
Type 1 diabetes (IMPACT trial: 38% less hypoglycemia), Type 2 diabetes (FreeDM2 trial: 0.6% greater A1c reduction; RELIEF study: 67% fewer hospitalizations), gestational diabetes (Plus models cleared for pregnancy), and patients with hypoglycemic unawareness. The 1-minute reading frequency reveals granular glucose patterns for precise medication titration.
