Do You Need a Prescription for a CGM?
Do You Need a Prescription for a CGM?
Many people ask whether you need a prescription to buy a continuous glucose monitor, especially when looking for a cash-pay option online.
For most traditional CGM systems, yes — a prescription is still required. Dexcom says a prescription is required for Dexcom G7, and Abbott says the FreeStyle Libre 3 system requires a valid prescription.
At the same time, the FDA has cleared some newer over-the-counter CGM products for certain adults, such as Dexcom Stelo for adults 18 and older who do not use insulin.
Which CGMs Usually Require a Prescription?
Prescription-required CGMs commonly include:
- Dexcom G7 sensors
- FreeStyle Libre 3 sensors
- FreeStyle Libre 3 Plus sensors
- FreeStyle Libre 2 Plus sensors
Dexcom states that a prescription is required for Dexcom G7, and Abbott states that FreeStyle Libre personal CGM systems require a prescription.
Can You Buy a CGM Without Insurance?
Yes — many people buy CGM systems as cash-pay customers instead of going through insurance. Buying without insurance can help avoid prior authorization delays and extra paperwork, though prescription-required CGMs still generally need a valid prescription. Dexcom also notes pharmacy savings options for people without CGM coverage.
