Talk with your doctor and get a prescription

You may need to help your doctor comprehend why this technology will be good for you and why you want it.

The main thing you need from your doctor is a prescription. You can share the links below with your doctor to help them understand the clinical benefits. To avoid delays, ask your doctor to make sure they write out important details in the prescription, such as the fact that you will use the device everyday.

Tips for talking with your doctor

  • Remember, you are in charge of your body.
  • Advocate for yourself with a list of reasons why you believe it is best for your lifestyle.
  • Bring a family member or trusted friend to support you.

Get insurance approval

Once you have the prescription, the process of getting insurance approval can feel like you’re jumping through many hoops (sometimes you are), but it will be worth it.

There are two ways to get coverage. Some insurance companies have "Pharmacy Benefit" and some cover sensors through "Durable Medical Equipment (DME)".

Contact the company you want a CGM from

CGM companies want your business and often have a helpful person on staff who understands the “ins and outs” of getting coverage. They will often walk you through the steps to confirm coverage. You will need your insurance card with your insurance policy number.


Pre-authorization is the process that some insurance companies make you go through to get coverage for a sensor. The insurance or CGM company will let you know what is required if you need pre-authorization. Sometimes a letter of Medical Necessity may be required from your doctor, in addition to the prescription.


Some insurance companies require your last month or more of blood sugar logs and/or A1c test results.

Wait time

Once you’ve submitted all your paperwork you may be able to move the process along by checking up every 1-2 weeks on the status. After a couple of weeks, it is absolutely justified to make a check-in call.


Get your sensor

Where you get your supplies depends on how you get your supplies covered by insurance.

If your insurance covers sensors through “Durable Medical Equipment”, the best way to get your supplies it to call the sensor company. If you’re getting your supplies through “pharmacy benefit”, you will need your prescription sent to the pharmacy. Call them to make sure they have ordered the sensors and then go pick it up!

You can say, "Hi, i'm interested in getting a sensor, can you help me with that?"
