Blood sugar monitors

Medicare Part B (Medical Insurance)

 covers blood glucose (blood sugar) monitors as durable medical equipment (DME) that your doctor prescribes for use in your home.

Your costs in Original Medicare

After you meet the

Part B Deductible

, you pay 20% of the 

Medicare-Approved Amount

 (if your supplier accepts 

assignment

). Medicare pays for different kinds of DME in different ways. Depending on the type of equipment:

  • You may need to rent the equipment.
  • You may need to buy the equipment.
  • You may be able to choose whether to rent or buy the equipment.

Medicare will only cover your DME if your doctors and DME suppliers are enrolled in Medicare. Doctors and suppliers have to meet strict standards to enroll and stay enrolled in Medicare. If your doctors or suppliers aren’t enrolled, Medicare won’t pay the claims they submit. 

Make sure your doctors and DME suppliers are enrolled in Medicare. It’s also important to ask a supplier if they participate in Medicare before you get DME. If suppliers are participating in Medicare, they must accept assignment (which means, they can charge you only the coinsurance and Part B deductible for the Medicare‑approved amount). If suppliers aren’t participating and don’t accept assignment, there’s no limit on the amount they can charge you. 

Things to know

Note

To find out how much your test, item, or service will cost, talk to your doctor or health care provider. The specific amount you’ll owe may depend on several things, like:

  • Other insurance you may have
  • How much your doctor charges
  • If your doctor accepts assignment
  • The type of facility
  • Where you get your test, item, or service
