Physician-Interpreted Continuous Glucose Monitoring (CGM) in Plano, TX

Unlock 24/7 metabolic intelligence without fingersticks. In-office placement of Dexcom G7 and FreeStyle Libre 3 micro-sensors paired with licensed glycemic pattern analysis to achieve >70% Time-in-Range (TIR).

Traditional Hemoglobin A1C testing provides only a 90-day historical average, masking dangerous post-prandial glycemic spikes and nocturnal hypoglycemic events that damage vascular endothelium. At Collin Health Partners, our internal medicine and diabetes specialists utilize medical-grade Continuous Glucose Monitoring (CGM) systems (Dexcom G7 and Abbott FreeStyle Libre 3). We apply the sensor in-office (CPT 95250), calibrate cellular telemetry, and conduct formal physician interpretation (CPT 95251) across 14-day ambulatory glucose profile (AGP) curves. By connecting continuous glucose telemetry with targeted dietary macros and GLP-1 therapy, patients achieve tight glycemic control and rapid metabolic reversal.

Who is a good candidate

  • Type 2 Diabetes Mellitus (E11.9) with fluctuating glycemic control or elevated A1C > 7.0%
  • Prediabetes (R73.03) or Metabolic Syndrome seeking aggressive lifestyle and medical reversal
  • Patients on insulin or secretagogues requiring protection against nocturnal hypoglycemia
  • Adults undergoing GLP-1 weight loss therapy desiring real-time nutritional feedback

Treatment protocol

  • Step 1: In-Office Sensor Application & Pairing — A water-resistant, ultra-thin micro-filament sensor (Dexcom G7 or FreeStyle Libre 3) is painlessly applied to the posterior upper arm in our clinic and paired with your smartphone app.
  • Step 2: 14-Day Interstitial Telemetry Capture — The sensor captures interstitial glucose readings every 1 to 5 minutes 24 hours a day, recording glycemic responses to meals, exercise, stress, and sleep without routine fingersticks.
  • Step 3: AGP Glycemic Curve Physician Analysis — Our licensed physicians download the standardized Ambulatory Glucose Profile (AGP) report, calculating Mean Glucose, Glucose Management Indicator (GMI), and Glycemic Variability coefficient (%CV).
  • Step 4: Medical & Pharmacotherapy Optimization — We adjust insulin titration, GLP-1 dosing, or metformin timing while fine-tuning meal macronutrients to consistently maintain >70% of readings within target range (70–180 mg/dL).

Frequently asked questions

Does Medicare cover Continuous Glucose Monitors (CGMs)?

Yes. Medicare expanded CGM coverage criteria to include patients with Type 1 or Type 2 diabetes who use insulin OR who have a documented history of problematic hypoglycemia, as well as those requiring tight glycemic control to prevent diabetic complications.

Is CGM sensor placement painful?

Application is virtually painless. The one-touch applicator deploys a hair-thin flexible filament just beneath the skin in less than a second. Most patients report feeling nothing more than a slight tap.

Can I shower, swim, or exercise while wearing a CGM?

Yes. Both Dexcom G7 and FreeStyle Libre 3 sensors are water-resistant (IP28/IP27 rated), allowing you to shower, swim in depths up to 8 feet for 30 minutes, and perform rigorous athletic workouts.
