If you or someone you're caring for has an ostomy, the pouches and supplies add up fast, and you're probably wondering whether Medicare pays for any of it. Short answer: yes. Medicare Part B covers ostomy supplies for people who've had a colostomy, ileostomy, or urinary ostomy, and after you meet the Part B deductible you generally pay 20% of the cost.

Does Medicare Cover Ostomy Supplies?

Yes. Medicare Part B covers ostomy supplies as part of its prosthetic device benefit, the category that pays for items replacing a body function you've lost. That applies whether you've had a colostomy, an ileostomy, or a urinary ostomy.

What Part B pays for here is the pouch itself and the supplies directly related to caring for your ostomy. This isn't a gray area or an administrative favor. It's written into federal regulation: 42 CFR 410.36 lists colostomy bags and supplies directly related to colostomy care among the prosthetic devices Medicare Part B covers.

So if a supplier or a plan tells you ostomy supplies aren't a Medicare benefit, that's simply wrong. They're covered, and they have been for a long time.

What You'll Pay for Ostomy Supplies

Once you've met the annual Part B deductible ($283 in 2026), you generally pay 20% of the Medicare-approved amount for your ostomy supplies, and Medicare picks up the other 80%.,

That 20% is your ongoing share for as long as you need supplies, month after month. Two details are worth understanding so the number doesn't surprise you:

  • It's 20% of the Medicare-approved amount, not whatever price a supplier might otherwise charge. Medicare sets the approved amount, and your coinsurance is figured on that.
  • The deductible resets each year. You pay the $283 once at the start of the year (across all your Part B services, not just ostomy supplies), and after that it's the 20% coinsurance.

If you want to see how the Part B deductible fits your other Medicare costs for the year, the full breakdown of what Medicare costs walks through it.

How Many Ostomy Supplies Medicare Covers

A fair question, since output and skin needs vary a lot from one person to the next. The rule ties the quantity to your doctor rather than to a fixed ration: Medicare covers the amount of supplies your treating doctor or provider says you need based on your condition.

In practice, that means the quantity your provider documents as medically necessary is what Medicare pays for. If your situation means you go through more pouches or barriers than a typical month, that documentation is what supports the larger order. It's worth keeping your provider's notes current if your needs change, since the paperwork is what your supplier and Medicare work from.

Getting Your Supplies From the Right Supplier

Coverage is one thing; keeping your actual bill to that 20% is another, and it comes down to where you get your supplies.

Because your share is 20% of the Medicare-approved amount, you'll want a supplier that's enrolled in Medicare and accepts assignment, meaning they agree to Medicare's approved amount as full payment. That's what keeps your cost predictable instead of leaving you on the hook for extra charges. Ostomy supplies are handled through Medicare's supplier system much like other medical equipment and supplies, so the same "is this supplier enrolled and accepting assignment" question applies.

One more wrinkle: if you're on a Medicare Advantage plan (Part C) instead of Original Medicare, your plan handles these supplies, and its copays and its list of approved suppliers can work differently from Original Medicare. Check your plan's rules and network before you order so you're not caught off guard.

Frequently Asked Questions

Does Medicare cover colostomy bags?

Yes. Colostomy bags are the classic example of a covered ostomy supply. Federal regulation (42 CFR 410.36) specifically names colostomy bags and supplies directly related to colostomy care as prosthetic devices Medicare Part B covers, and they're billed like any other ostomy supply.

Are ostomy supplies covered under Part A or Part B?

Part B. Ostomy supplies fall under Part B (Medical Insurance), through its prosthetic device benefit, because they're ongoing supplies you use at home. Part A is your hospital insurance, so it isn't where the pouches and barriers you reorder month after month come from.

What if I have a Medicare Advantage plan?

Medicare Advantage plans deliver your benefits instead of Original Medicare, so your ostomy supplies go through the plan. Your out-of-pocket cost and which suppliers you can use may differ from Original Medicare, so contact your plan directly to confirm its coverage rules, network, and any prior authorization before you order.
