Continuous Glucose Monitoring
Continuous Glucose Monitors for Remote Monitoring Programs
A fingerstick shows one moment. A continuous glucose monitor shows the overnight low the patient slept through and the post-meal spike they never felt. HealthArc brings CGM data into the same dashboard as every other vital your care team reviews, with time-in-range, trend alerts and the documentation your billing needs.

Overview
Why Remote Continuous Glucose Monitor Monitoring Works
Continuous glucose monitoring changed what diabetes management can look like. Instead of a handful of chosen moments, a CGM produces a curve, and that curve reveals the two things fingersticks systematically miss: what happens overnight, and what happens in the two hours after a meal.
The clinical value is well established. The operational problem is that CGM data usually lives in a manufacturer’s own portal, separate from every other program your care team runs. HealthArc pulls that data into the same workflow as blood pressure, weight and oximetry, so one care manager reviews one patient in one place.
CGM strengthens RPM for insulin-treated diabetes and supports endocrinology and CCM programs on the same platform. Every device in the HealthArc device family reports into one dashboard and one monthly billing record, not a separate portal per vendor.
Device Features
Built for Clinical Programs, Not Consumers
CGM integration for diabetes and RPM programs: continuous readings, time-in-range reporting and threshold alerts inside the same platform as blood pressure, weight and oximetry.
Time-in-Range Reporting
Time in range, time above and time below are calculated for each patient and each period, giving your team the metric diabetes guidelines increasingly center on.
Nocturnal Hypoglycemia Detection
Overnight lows, the events patients sleep through and fingerstick regimens rarely catch, surface as alerts your team can act on.
Post-Meal Excursion Patterns
Post-prandial spikes become visible as a pattern rather than an occasional high reading, which is what makes targeted regimen changes possible.
One Dashboard, Every Signal
CGM data sits alongside blood pressure, weight and medication adherence for the same patient, instead of in a separate manufacturer portal your staff has to check.
Documentation for Billing
Readings, interpretation and care-manager time are captured against the patient record to support CGM and RPM billing requirements.
Fits Existing Prescribing
Works with the CGM your endocrinology or primary care team already prescribes, rather than requiring you to standardize on new hardware.
How It Works
From the Patient’s Home to Your Dashboard
Four steps, none of which require the patient to own a smartphone, install anything or report a number to anyone.
1
The device ships activated
HealthArc procures, configures and ships the continuous glucose monitor directly to the patient, along with enrollment support and training. It works out of the box, and there’s no pairing sequence for your staff to talk anyone through.
2
The patient takes a reading
One action. No app to open, no account to sign into. That simplicity is what keeps adherence intact past the first few weeks.
3
Data transmits over cellular automatically
The reading moves to the HealthArc platform over the mobile network, encrypted and time-stamped. That happens in seconds. Nothing is transcribed by hand, so nothing is mistyped or forgotten.
4
Your team reviews, acts and bills
Readings are checked against the thresholds you set for that patient, alerts route to the care team, and monitoring days plus management time accumulate into a billing-ready monthly record.
Specifications
Continuous Glucose Monitor Specifications
What the device measures, how it connects, and what the patient has to do. The short answer to the last one is: take the reading.
No apps. No pairing. No Wi-Fi. Cellular connectivity is the reason HealthArc programs can enroll patients who don’t own a smartphone or have home broadband. Typically the highest-risk patients in the panel.
| Measurement | Interstitial glucose, sampled continuously through the wear period |
|---|---|
| Reporting | Time in range, time above/below, glucose variability, trend curves |
| Alerts | Configurable hypo- and hyperglycemia thresholds, including overnight |
| Wear period | Per sensor manufacturer specification |
| Integration | CGM data surfaced alongside RPM vitals in one dashboard |
| Billing support | CPT 95249, 95250 and 95251 documentation, plus RPM codes where applicable |
| Data security | Encrypted in transit and at rest, HIPAA-compliant infrastructure |

Codes This Device Supports
HealthArc tracks transmission days and management time against each code automatically, so a month either meets the billing threshold or visibly does not.
95249
Patient-owned CGM: startup, sensor placement, training and printout.
95250
Provider-owned CGM: a minimum of 72 hours of continuous recording.
95251
Analysis, interpretation and report by the clinician.
99457
RPM management time, where the program also meets RPM requirements.
Code requirements, payment rates and monitoring-day thresholds change with each Medicare Physician Fee Schedule. Confirm current requirements in the CPT code library and with the CMS Fee Schedule Look-Up Tool before billing.

FAQ
Frequently Asked Questions
What is the difference between a CGM and a glucometer?
A glucometer gives a precise reading at a moment the patient chooses. A CGM samples interstitial glucose continuously, producing a curve that reveals overnight lows and post-meal spikes a fingerstick regimen would never capture. Many programs use both: CGM for insulin-treated patients, fingerstick meters for the rest.
Which CPT codes apply to CGM?
CGM has its own codes: 95249 for patient-owned sensor startup and training, 95250 for provider-owned CGM with at least 72 hours of recording, and 95251 for the clinician’s analysis and interpretation. RPM codes may apply alongside them when the program independently meets RPM requirements. See our CPT code library.
Can we bill CGM and RPM in the same month?
Potentially, when the services are distinct and the time is not counted twice. The rules are specific and payer policy varies, so confirm current CMS guidance and your payer’s policy before billing both for the same patient in the same period.
Do we have to change which CGM we prescribe?
No. The intent is to bring the data your team already generates into one clinical workflow, not to make you standardize on different hardware.
What is time in range and why does it matter?
Time in range is the percentage of the day a patient’s glucose stays within their target band. It has become a central diabetes metric because it captures variability and hypoglycemia risk that an A1c average conceals.
