Check If I Qualify

Step 1: Your basic info

I have a diabetes diagnosis (my doctor can document this).

I can provide my insurance information when asked.

Step 2: I qualify for a CGM if ONE is true

I am treated with insulin.

I have a history of problematic low blood sugar (hypoglycemia) documented by my provider, including one of these:

More than one low blood sugar event below 54 mg/dL that continued even after treatment/med changes.

One low blood sugar event below 54 mg/dL where I needed help from someone else.

Step 3: Provider visit timing (important)

I've had a visit with my treating provider (in-person or Medicare-approved telehealth) within the last 6 months to evaluate my diabetes and document CGM need.

Step 4: Prescription & training

My provider will write a CGM prescription (this also shows I'm trained or will be trained to use it).

Step 5: Staying covered (after you start CGM)

I understand I need a follow-up provider visit (in-person or Medicare-approved telehealth) every 6 months to keep coverage and document continued use.
