Your Medicare Coverage

Is my test, item, or service covered?

Commode chairs

How often is it covered?

Medicare Part B (Medical Insurance) covers commode chairs as durable medical equipment when ordered by a doctor for use in your home if you're confined to the bedroom.

Who's eligible?

All people with Part B are covered.

Your costs in Original Medicare

If your supplier accepts assignment, you pay 20% of the Medicare-approved amount, and the Part B deductible 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, or 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. If you have Original Medicare and get competitively bid equipment and supplies in competitive bidding areas, Medicare may only help pay for these equipment and supplies if they're provided by contract suppliers. 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.


If your current supplier doesn’t get a new contract, you may still be able to stay with that supplier if they decide to participate in the program as a “grandfathered” supplier. Suppliers that don’t get Medicare contracts can decide to become "grandfathered" suppliers. This means a supplier may continue to rent equipment to you if you were renting the equipment when the program started. This rule applies to oxygen, oxygen equipment, and certain rented equipment. You may continue using the “grandfathered” supplier until the rental period for your equipment ends.

If you start renting additional equipment from a “grandfathered” supplier after the program starts, Medicare won’t pay for the new equipment.

If you’re renting equipment that’s eligible for grandfathering, your supplier will let you know in writing 30 business days before the program begins whether it will or won’t become a “grandfathered” supplier.

What happens if my supplier decides not to become a grandfathered supplier?

You need to decide whether to continue to rent from your current supplier and pay all the costs, or switch to a Medicare contract supplier. 

A supplier that doesn’t have a new contract and decides not to become a grandfathered supplier is required to notify you and pick up the item from your home after the program starts. Your supplier must notify you these 3 ways before it can pick up the item:

  • The supplier must send you a letter at least 30 business days before the program starts telling you that it will no longer provide rental items to you after a certain date. This letter will tell you the date that a Medicare contract supplier must start to provide you with the rented item.
  • The supplier must call you 10 days before picking up the item to make arrangements for pick up at an agreed upon time.
  • The supplier must call you again 2 business days before picking up the item.

A supplier that isn’t grandfathered can't pick up a medically necessary item before the end of the last rental month for which the supplier is eligible to get a rental payment, even if the end of the last rental month occurs on or after January 1, 2014.

If you change to a Medicare contract supplier, your old supplier should work with the contract supplier so there isn’t a break in service. Keep the pickup slip or other documentation from the supplier that shows you no longer have the item.

Under current Medicare rules, you own these types of equipment after renting for 13 months. When you switch to a Medicare contract supplier instead of using a "grandfathered" supplier or other non-contract supplier, your 13-month rental period will start over, so you won't own the equipment until after the new rental period ends. This will extend your rental period and result in additional months of coinsurance. However, the amount you pay may be lower because the amount you'll pay will be based on the new payment rates under the new program.

  • Once you own the equipment, you must get replacement supplies and accessories for the equipment from a contract supplier in order for Medicare to help you pay for these items. You may get repairs for the equipment you own from any Medicare-approved supplier (even a non-contract supplier), including replacement parts needed for the repair.
  • If you already own your equipment, you must use a Medicare contract supplier for your replacement supplies and accessories.

To find out how much your specific test, item, or service will cost, talk to your doctor or other 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, and the location where you get your test, item, or service.
