The short answer
Medicare's coverage of incontinence and ostomy supplies is a mixed bag, and knowing the line saves a lot of frustration. Ostomy supplies and urinary catheters are generally covered as durable medical equipment or prosthetic supplies under Part B when a doctor prescribes them. Absorbent products — adult diapers, pads, and liners — are generally not covered by Original Medicare.
That gap on absorbent products surprises caregivers, because those are often the day-to-day expense. There are ways to help, but they usually come from somewhere other than Original Medicare.
What is covered
If you have an ostomy, Medicare covers the pouches, skin barriers, and related supplies you need, in reasonable quantities, when prescribed. Urinary catheters and related supplies are covered for people who meet the medical criteria — for example, someone with a condition that requires catheterization.
These come under Part B, so your normal deductible and coinsurance apply unless you have coverage that fills the gap. You'll get them through a supplier that bills Medicare. Our guide to Medicare and durable medical equipment explains how the supplier process works.
What isn't — and the workarounds
Adult diapers and absorbent pads are the big non-covered item under Original Medicare. Here's where families find help: some Medicare Advantage plans include an over-the-counter benefit that can be used for absorbent products, and full Medicaid (for people who are dual-eligible) often covers incontinence supplies that Medicare won't.
So if absorbent products are a real monthly cost, two questions are worth asking: does a Medicare Advantage plan in the area include an OTC allowance that covers them, and does the person qualify for Medicaid help? For families managing a parent's care, our caregiver guide to Medicare covers how to coordinate these pieces.
