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.
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
Your doctor or other health care provider may recommend you get services more often than Medicare covers. Or, they may recommend services that Medicare doesn’t cover. If this happens, you may have to pay some or all of the costs. Ask questions so you understand why your doctor is recommending certain services and if, or how much, Medicare will pay for them.
