What ostomy supplies does Medicare cover?
Medicare Part B covers medically necessary ostomy supplies, which help people manage bodily waste after ostomy surgery. Part B covers them under the prosthetic device benefit, and Medicare.gov lists ostomy bags and certain related supplies among the prosthetic devices Part B covers when a doctor or other health care provider orders them.
Who qualifies for ostomy supply coverage?
You're eligible if you've had one of these surgeries:
- A colostomy
- An ileostomy
- A urinary ostomy
How many ostomy supplies will Medicare cover?
Medicare covers the amount of supplies your doctor or other health care provider says you need, based on your condition. Medicare.gov's ostomy page doesn't set a fixed monthly number, so talk with your doctor if the amount you've been prescribed doesn't meet your needs.
What do I pay for ostomy supplies?
After you meet the Part B deductible ($283 in 2026), you pay 20% of the Medicare-approved amount for your doctor's services and supplies. Medicare only pays for a prosthetic device from a supplier that participates in Medicare, whether you or your provider submits the claim.
A supplier that accepts assignment agrees to charge you only the Medicare deductible and coinsurance and has to submit your claim directly to Medicare. What you owe also depends on any other insurance you have, how much your doctor charges, the type of facility and where you get your supplies.
Does Medicare Advantage or Medigap change this?
Medicare Advantage plans cover almost all medically necessary services Original Medicare covers, and some offer extra benefits; in many cases you need to use the plan's network, and costs vary by plan, so check with the plan about ostomy supplies. See What is the difference between Original Medicare and Medicare Advantage?.
With Original Medicare, a Medigap (Medicare Supplement Insurance) policy may help cover some of your costs for prosthetic items like ostomy bags, according to Medicare's equipment booklet.
