Continuous Blood Glucose Sensor Evaluation


Referrals & Appointments

How to find us
Our location

The data obtained from wearing one of our Continuous Glucose Sensors can provide a better picture of your diabetes management. This allows us to develop a plan of action to get your diabetes under better control.

What is a sensor?

A sensor is a short, thin wire inserted under your skin. It is usually placed on the abdomen. A transmitter (about the size of a quarter) is connected to your sensor. The transmitter collects and stores BG readings every 5 minutes. The transmitter is water-proof and can be worn for bathing, showers and swimming.

You will need a doctor's order to wear one of our Glucose Sensors.

Almost all insurance companies provide coverage for a patient to wear a sensor.

Medicare provides coverage that allows a patient to wear a sensor twice a year.

We recommend you check with your insurance to ensure you do have coverage and what your financial responsibility might be. The insurance code for this service is 95250. To make things easier for you when calling your insurance company, ask to speak to the chronic disease manager for diabetes. Most insurance plans provide this service.

So what would the process be if I wore a sensor for 3-7 days?

  • You will need an order for Continuous Glucose Sensor from your physician
  • Make an appointment for 1 hour with one of our diabetes educators
  • Insertion of the sensor involves minimal discomfort and takes just a few minutes.
  • Before leaving you would need to set up a follow-up appointment within the next week.
  • Bring the transmitter, your BG meter and your log sheets to your follow-up appointment.
  • Your educator will download the transmitter on the computer.
  • You will be able to see your sensor reports and your educator will explain what the reports mean.
  • A copy of the reports will be forwarded to your doctor.
  • Your doctor will make adjustments to your diabetes management as indicated.

What do I have to do when I am wearing a sensor?

You will need to:

  • Keep a detailed food and activity log.
  • Test your blood glucose 2 - 4 times daily in order to calibrate the sensor.
  • Use the same blood glucose meter while wearing a sensor.
  • Return with the food and activity log, the transmitter and the blood glucose meter so your diabetes educator can download the transmitter.
