What ostomy supplies are and why you need them

An ostomy is an opening in your abdomen created during surgery that lets waste leave your body into an external pouch instead of through the normal route. Ostomy supplies are the pouches, skin barriers, and cleaning products you use to manage that opening safely and comfortably. The most common types are colostomies (for bowel waste), ileostomies (for small intestine waste), and urostomies (for urine).

You need these supplies because the opening itself produces waste continuously and can irritate your skin if left unprotected. The pouches collect that waste so you can empty them when full. Skin barriers—thin wafers that stick around the opening—protect the skin underneath from moisture and chemicals in the waste. Without them, the skin breaks down quickly and becomes painful.

Most people with an ostomy change their pouch every few days to a week, depending on the type and how their body works. You'll also need wipes, adhesive removers, and sometimes powders or pastes to keep the seal tight and the skin healthy. These aren't one-time purchases—they're ongoing supplies you'll need for life after ostomy surgery.

Key Takeaways

  • Ostomy pouches and skin barriers are medical supplies, not over-the-counter products, and most insurance plans cover them partly or fully.
  • Medicare covers ostomy supplies if you have a prescription from your doctor, and the amount varies by whether you use Original Medicare or a Medicare Advantage plan.
  • Private insurance usually covers supplies through durable medical equipment (DME) benefits, but you may need prior authorization and must use an in-network supplier.
  • If you don't have insurance or your coverage is limited, patient information programs run by ostomy supply manufacturers can reduce or cover your costs.
  • Your doctor's prescription must specify the exact type, size, and quantity of supplies you need each month for insurance to pay.

How Medicare covers ostomy supplies

If you have Original Medicare (Parts A and B), ostomy supplies fall under the durable medical equipment (DME) benefit. Medicare will cover pouches, barriers, and related supplies if your doctor writes a prescription saying you need them. You pay 20 percent of the approved amount after you've met your Part B deductible (which is $240 in 2024, though this changes yearly). Medicare then pays the remaining 80 percent.

The catch is that Medicare sets a fixed monthly allowance for ostomy supplies based on the type of ostomy you have. For example, a colostomy might have a different allowance than an ileostomy. You can order supplies up to that monthly limit without extra cost, but if you want premium brands or more supplies than the allowance covers, you pay the difference yourself. You must order through a Medicare-approved DME supplier, and that supplier must be in your state.

If you have a Medicare Advantage plan (Part C), coverage works differently. Each plan sets its own rules for ostomy supplies—some cover them fully, others require copays, and some have quantity limits. You'll need to call your plan directly to find out what your specific coverage includes and which suppliers you can use.

Private insurance and employer plans

Most private insurance plans cover ostomy supplies through their DME benefit, similar to Medicare. Your out-of-pocket cost depends on your plan's deductible, copay, and coinsurance. Some plans cover supplies at 80 percent after you meet your deductible; others cover them at 100 percent with no copay. The only way to know is to call your insurance company and ask specifically about ostomy supplies.

Insurance companies often require prior authorization before they'll pay. This means your doctor has to submit a prescription and justification to the insurance company first, and the company approves it before you order. This can take a few days to a week. Some insurers also require you to use a specific in-network DME supplier, and if you use an out-of-network supplier, you'll pay more or the claim won't be covered at all.

If your plan has a quantity limit—for example, "one pouch per day"—and you need more, you can ask your doctor to request an exception. Insurance companies sometimes approve higher quantities if your doctor documents medical necessity, such as a high-output ostomy or skin sensitivity that requires more frequent changes.

Medicaid coverage by state

Medicaid covers ostomy supplies in all states, but the specifics vary widely. Some states cover supplies with no copay; others charge a small copay per item. Some states have quantity limits; others don't. Some require prior authorization; others don't. Because Medicaid is run by each state, you need to contact your state's Medicaid program directly to learn what you're covered for.

To find your state Medicaid office, go to Medicaid.gov and select your state. You can also call your state's Medicaid customer service line—the number is usually on the back of your Medicaid card. Have your Medicaid number ready and ask specifically about ostomy supplies, what's covered, what your copay is, and which suppliers are in-network.

If you may have access to for both Medicaid and Medicare (called "dual may be able to access"), Medicaid is usually your primary payer for ostomy supplies, meaning Medicaid pays first and Medicare covers what Medicaid doesn't. Your out-of-pocket cost will be whatever your state's Medicaid program charges.

Uninsured and underinsured options

If you don't have insurance or your insurance doesn't cover ostomy supplies, several manufacturers run patient information programs that provide supplies for free or at a reduced cost. The major ostomy supply makers—Coloplast, ConvaTec, Hollister, and B. Braun—all have these programs. You typically need to fill out an process and provide proof of income. Processing takes one to two weeks, and supplies are usually mailed to your home.

To find these programs, search the manufacturer's website for "patient information" or "financial support." You can also ask your doctor's office or an ostomy nurse to help you explore—many offices have staff who specialize in connecting patients with these programs. Some programs require a prescription from your doctor; others don't.

Another option is to contact the United Ostomy Associations of America (UOAA), a nonprofit that connects people with ostomies to resources and support. They maintain a list of information programs and can point you toward local resources in your area. Their website is uoaa.org.

What your prescription needs to include

For insurance to cover ostomy supplies, your doctor's prescription must be specific. It can't just say "ostomy supplies." It needs to include the type of ostomy (colostomy, ileostomy, or urostomy), the size of the pouch opening, whether you use a one-piece or two-piece system, the brand or generic equivalent, and the quantity you need per month. For example: "Coloplast SenSura Mio one-piece pouches, 40 mm, 30 per month."

If your prescription is vague, the insurance company or DME supplier will send it back to your doctor for clarification, which delays your order by several days. If you're not sure what you need, ask your ostomy nurse or the DME supplier to help you figure out the right specifications before your doctor writes the prescription. Many DME suppliers have nurses on staff who can guide you through this.

Your prescription is also valid for a set time—usually one year. After that, you need a new prescription from your doctor. Some doctors will write standing prescriptions that renew automatically; others require you to call and request a new one each year. Ask your doctor's office how they handle this so you don't run out of supplies.

Finding a DME supplier and ordering

Once you have a prescription and know your insurance coverage, you need to find a DME supplier. If you have Medicare, you can search for approved suppliers at the Medicare website (Medicare.gov) or call 1-800-MEDICARE. If you have private insurance or Medicaid, your insurance company can tell you which suppliers are in-network.

Many national suppliers deliver by mail, which is convenient if you don't want to pick up supplies in person. Local medical supply stores also carry ostomy supplies and can help you fit and adjust your pouch if you're new to using one. Some people prefer mail delivery for privacy; others prefer a local store where they can talk to someone face-to-face.

When you call a supplier, have your insurance information and prescription ready. The supplier will verify your coverage, confirm what your insurance will pay, tell you what you owe out-of-pocket, and set up a delivery schedule. Most suppliers can start delivering within a few days to a week. If you need supplies urgently before your regular delivery arrives, many suppliers will rush-ship for an extra fee, or you can buy a small amount out-of-pocket at a pharmacy or medical supply store to tide you over.

Frequently Asked Questions

Do I need a prescription to buy ostomy supplies?

For insurance to cover them, yes. If you're paying out-of-pocket, you can buy many supplies without a prescription at pharmacies or online retailers, but a prescription from your doctor is required for Medicare, Medicaid, and most private insurance to pay.

Can I switch brands if my insurance only covers one?

Sometimes. If your insurance covers a specific brand and you want a different one, ask your doctor to request an exception, explaining why the covered brand doesn't work for you (skin irritation, poor fit, leakage). Insurance companies often approve exceptions if your doctor documents medical necessity.

What if I use more supplies than my insurance allows?

You can pay out-of-pocket for the extra supplies, or ask your doctor to request a quantity increase from your insurance company. If your ostomy output is higher than average or your skin is sensitive, your doctor can document this and ask the insurance company to approve a higher monthly allowance.

Are ostomy supplies covered if I'm on a student health plan?

Student health plans vary widely. Some cover ostomy supplies as DME; others don't. Contact your school's health insurance office or call the plan directly. If your student plan doesn't cover them, you may be able to stay on a parent's plan until age 26, or you can look into patient information programs from manufacturers.

How do I know if a supplier is legitimate?

Check that they're on your insurance company's in-network list or, for Medicare, that they're listed on Medicare.gov as an approved supplier. Legitimate suppliers will ask for your prescription and insurance information before taking your order. Be cautious of suppliers who don't ask for these details or who pressure you to order large quantities upfront.
