• 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 submitted by them. 

It’s also important to ask your suppliers if they participate in Medicare before you get DME. If suppliers are participating suppliers, they must accept assignment. If suppliers are enrolled in Medicare but aren’t “participating,” they may choose not to accept assignment. If suppliers don't accept assignment, there’s no limit on the amount they can charge you.

Competitive Bidding Program

If you live in or visit certain areas, you may be affected by Medicare's Competitive Bidding Program. In most cases, Medicare will only help pay for these equipment and supplies if they're provided by contract suppliers when both of these apply:

• You have
  Original Medicare
  .
• You get competitively bid equipment and supplies in competitive bidding areas.

Contract suppliers can't charge you more than the 20% coinsurance and any unmet yearly deductible for any equipment or supplies included in the Competitive Bidding Program.
