What a CGM costs with Medicare

What you pay with Original Medicare. What the monthly supply payment buys. And why using only your phone can cost you.

Your share

With Original Medicare you pay 20% of the Medicare-approved amount after the Part B deductible.^[1]
That 20% applies when the supplier accepts assignment. A supplier that takes part in Medicare must accept it.^[1]

The device itself and the monthly supplies are paid as two separate items.^[2],[3]
The supply payment covers the sensors and anything else the device needs to work.^[3]
For a CGM you can dose from, it also covers a fingerstick meter, strips and lancets if you need them.^[3]
A supplier can bill up to three months at once. It may not send you more than a 90-day supply.^[3]

Medicare pays for supplies when you use a reader, or a pump, that Medicare counts as equipment.^[3]
You may use your phone too, or use the reader on some days and your phone on others.^[3]
If you never use a reader or pump to see your numbers, Medicare does not pay for the supplies.^[3]
