My first supply order arrived about two weeks after I got home from the hospital. I ripped open the box, grateful to have everything I needed — and then I saw the bill tucked inside.
Hundreds of dollars. For pouches. For flanges. For the tape and barrier rings I was already going through faster than I expected because I was still figuring out my system. I sat at my kitchen table and felt a very specific kind of overwhelmed — the kind that mixes shame with panic, because I had just been through cancer surgery and I was now supposed to budget my way through staying clean and functional every single day.
Here is what nobody told me in the hospital, and what I want to tell you right now: insurance covers this. Almost all of it. Private insurance, Medicare Part B, and Medicaid all treat ostomy pouching supplies as medically necessary durable medical equipment — because that is exactly what they are. The problem is not coverage. The problem is that nobody walks you through how to claim it.
This is that guide. Let's get you every dollar you are entitled to.
The Basics: Ostomy Supplies Are Covered
Let me be direct: ostomy supplies are covered by insurance. This is not a gray area, it is not a special exception, and it is not something you have to beg for. Pouching systems, skin barriers, tape, irrigation supplies, and related accessories are classified as Durable Medical Equipment (DME) — a category that all major insurance types are required to cover.
The three main coverage types are:
- Medicare Part B — for people 65+ and many people with disabilities
- Private/employer insurance — group plans and marketplace plans
- Medicaid — state-administered, income-based coverage
The challenge is not getting covered in principle — it is knowing which steps to take with each type of plan. Each one has its own process, its own terminology, and its own frustrating hoops. Here is what you need to know about each one.
Medicare Part B Coverage for Ostomy Supplies
If you have Medicare, Part B covers 80% of the Medicare-approved cost of ostomy pouching supplies — after you meet your annual Part B deductible. That 80% applies to:
Ostomy pouches (drainable and closed)
(one-piece and two-piece systems)
Skin barriers / wafers
(moldable, pre-cut, and flat or convex)
Ostomy tape and adhesive accessories
(belts, rings, paste)
Irrigation supplies
(for colostomy irrigation users)
Ostomy deodorants and related supplies
(in limited quantities)
The remaining 20% is your responsibility — unless you have a Medigap (Medicare Supplement) policy, which is specifically designed to cover that gap. If you have Medigap, your out-of-pocket cost for covered supplies can drop to zero.
How to use your Medicare coverage: Start by calling the ostomy supply vendor your hospital or surgeon recommends and asking specifically, “Do you bill Medicare Part B?” Most major suppliers (Byram Healthcare, Edgepark, Hollister Home Delivery) do. Once you're set up with an in-network supplier who bills Medicare directly, you generally don't have to do much — they handle the claim and you pay only your 20% share.
Check your Medicare Summary Notice (MSN) — mailed quarterly — to verify that claims are being processed correctly. If something looks wrong, call 1-800-MEDICARE.
Private / Employer Insurance Coverage
Private and employer-sponsored insurance plans cover ostomy supplies under the Durable Medical Equipment (DME) category. The coverage percentage, deductible, and annual limits vary by plan — but the category is almost universally covered.
The most common friction point with private insurance is prior authorization. Many plans require you (or your supplier) to get approval before they cover the supplies. Here is how to navigate it:
Get a Letter of Medical Necessity (LMN)
This is the most important document in your insurance toolkit. A Letter of Medical Necessity is a letter from your surgeon, gastroenterologist, or WOC nurse that states — in clinical terms — that you require ostomy supplies as a direct result of a medical condition. Insurance companies are significantly less likely to deny a prior authorization request that arrives with a detailed, signed LMN. Ask your surgeon's office for one at your first post-op visit.
Use an in-network DME supplier
Your insurance has a network of DME suppliers who have agreed to accepted rates. Using an out-of-network supplier can leave you with a much higher bill or a denial. Call the DME line on the back of your insurance card and ask for a list of in-network ostomy supply vendors. Most major national suppliers (Byram, Edgepark, Shield Healthcare) participate in multiple networks.
Know your DME benefit details
Ask your insurer specifically: What is my DME deductible? What percentage does the plan cover after deductible? Is there an annual supply quantity limit? Knowing these numbers in advance prevents surprises on the bill.
Appeal every denial
Insurance denials are not final. They are an opening move. If your claim is denied, request the denial in writing, note the reason code, and file an appeal. More on this in the section below — but do not accept a first denial as the last word.
Medicaid Coverage for Ostomy Supplies
Medicaid coverage for ostomy supplies varies by state, but in most states — including New Jersey and Pennsylvania, where much of our Beyond the Bag community is based — ostomy pouching supplies are covered benefits.
NJ FamilyCare (New Jersey's Medicaid program) covers ostomy supplies as medically necessary DME. Pennsylvania's Medical Assistance program does the same. If you are enrolled in a Medicaid Managed Care Organization (MCO), your specific MCO may have its own supplier network — your caseworker or the member services line can tell you which DME suppliers are in-network.
If you are unsure whether your state covers ostomy supplies, ask your caseworker these exact questions: “Are ostomy pouching supplies covered under my plan? What category are they listed under — DME or medical supplies? Which suppliers can I use?” Having the right vocabulary makes a real difference in getting clear answers.
How to Find an In-Network Ostomy Supplier
Finding the right supplier matters as much as having coverage. Here are the best starting points:
Call your insurer's DME line
The phone number on the back of your insurance card usually has a dedicated DME line or member services team. Call and ask: "I need to find an in-network supplier for ostomy pouching supplies. Can you give me a list?" Write down the names they provide.
UOAA Supplier Directory
The United Ostomy Associations of America (UOAA) maintains a supplier directory at ostomy.org. You can search by product type and supplier name to cross-reference with your insurance network.
Manufacturer patient assistance programs
Hollister, Coloplast, and ConvaTec — the three major ostomy supply manufacturers — all have patient assistance programs for people who are uninsured, underinsured, or who need supplies while their insurance coverage is being set up. Call their customer service lines directly and ask about financial assistance or sample programs.
Your surgeon or WOC nurse
Ask your care team which suppliers they work with most. Experienced ostomy programs have established relationships with DME suppliers who know how to handle insurance billing. A warm handoff from your care team to a supplier they know is often the smoothest start.
What to Do When a Claim Gets Denied
A denial is not a dead end. It is a bureaucratic opening move, and you are allowed — and expected — to push back. Here is the step-by-step process I want you to know by heart:
Request the denial in writing
You are entitled to a written explanation of any coverage denial, including the specific reason code or clinical justification. Call your insurer and ask for it. The written denial tells you exactly what to address in your appeal.
Get a Letter of Medical Necessity from your WOC nurse or surgeon
If you don't already have one, get it now. If you do have one, ask your provider to strengthen it — more clinical detail about your specific diagnosis, stoma type, and why your current supply regimen is medically necessary. A detailed LMN from a CWOCN carries significant weight.
File a formal appeal
Your insurer is required to have an appeals process. Follow it exactly — submit within their timeframe, include your LMN, include any supporting clinical documentation, and keep copies of everything you send. Most legitimate claims that are denied on first pass succeed on appeal when properly documented.
Request an external review if the internal appeal fails
If your internal appeal is denied, you have the right to an independent external review under the ACA. An independent organization — not affiliated with your insurer — reviews your case. External reviewers overturn internal denials at a meaningful rate.
Contact your state insurance commissioner
If you believe your insurer is wrongly denying a covered benefit, file a complaint with your state's insurance commissioner. In New Jersey: nj.gov/dobi. In Pennsylvania: insurance.pa.gov. Regulatory complaints often prompt insurers to reconsider denials faster than additional appeals.
Free and Low-Cost Supply Programs
Even if insurance is still being sorted out, you should not have to go without supplies. Here are real programs that can help:
UOAA Supply Assistance Program
The United Ostomy Associations of America connects ostomates in need with donated supplies through their chapters and national network. Visit ostomy.org or contact your local UOAA affiliate chapter to ask about supply assistance.
Manufacturer Sample Programs
Hollister, Coloplast, and ConvaTec all offer free product samples — especially if you are newly diagnosed or switching systems. Call the customer service number on any of their products and ask directly. Most will send 1–2 weeks of free supplies, no strings attached.
Ostomy Supply Exchange Groups
There are active Facebook groups dedicated to exchanging unused, unopened ostomy supplies between community members — people who switched systems, discontinued a product, or received too many supplies. Search "ostomy supply exchange" on Facebook. These communities are generous and real.
Nonprofit Medical Supply Banks
Many communities have local nonprofit medical supply banks or lending closets that distribute donated medical supplies. Contact your local Area Agency on Aging, community health centers, or a social worker at your hospital to find resources near you.
You fought hard enough already. Don't let a billing department take what you're entitled to.
I know insurance navigation feels like one more impossible thing when you are already exhausted from surgery, recovery, and adjusting to an entirely new body. I know the paperwork is overwhelming and the phone trees are maddening and the first denial feels like a wall.
But these are your supplies. This is your health. The coverage exists — it is written into your policy, mandated by law, and you have every right to claim it. Ask every question. Appeal every denial. Get the Letter of Medical Necessity. Call the DME line. File the complaint if you have to.
And if you are stuck — if you have hit a wall and you just need someone to help you figure out the next step — that is exactly what our 1:1 navigation consultations are for. You do not have to navigate this bureaucracy alone.
