Continuous passive motion devices
Medicare Part B (Medical Insurance)
covers knee continuous passive motion (CPM) machines as durable medical equipment (DME) that your doctor prescribes for use in your home, if you meet certain conditions. If you have knee replacement surgery, Medicare covers CPM devices for up to 21 days of use in your home.
Your costs in Original Medicare
If your supplier accepts
assignment you pay 20% of the
Medicare-Approved Amount, and the Part B
deductible [glossary] applies. 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 submitted by them.
Make sure your doctors and DME suppliers are enrolled in Medicare. It’s important to ask your suppliers if they participate in Medicare before you get DME. If suppliers are participating suppliers, 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. Medicare won’t pay claims for doctors or suppliers who aren’t enrolled in Medicare.

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
- Whether your doctor accepts assignment
- The type of facility
- Where you get your test, item, or service
Is my test, item, or service covered?
