Colostomy bags are available through online medical supply companies, directly from manufacturers, and through some pharmacies and home health suppliers. Most people end up ordering through a dedicated ostomy supply retailer, either online or by phone, because these companies carry the full range of sizes, styles, and brands that general pharmacies typically don’t stock.
Online Ostomy Supply Retailers
Specialty medical supply companies are the most common source for colostomy bags and accessories. These retailers focus specifically on ostomy products, so they carry multiple brands and system types (one-piece, two-piece, drainable, closed-end) in a wide range of sizes. Many also have staff who can help you match products to your needs over the phone.
Several lower-cost options are listed by the United Ostomy Associations of America, including Best Buy Ostomy Supplies (866-940-4555), Medical Monks (844-859-9400), Gilgal Medical Supplies (407-891-2120), and Lifeline Medical Supply. These companies often offer competitive pricing compared to what you’d pay at a local pharmacy, and most ship directly to your home on a recurring schedule if you set up auto-delivery.
Amazon and other general online marketplaces also sell colostomy bags, including cut-to-fit and pre-sized options. The selection is broad, but if you’re new to ostomy care, a specialty retailer with knowledgeable staff is a better starting point than sorting through hundreds of listings on your own.
Free Samples From Manufacturers
The three largest ostomy product manufacturers, Coloplast, Hollister, and ConvaTec, all offer free samples so you can try different products before committing to a full order. This is one of the most useful (and underused) options available, especially if you’re still figuring out which system works best for your body.
Coloplast, for example, lets you request free samples of their SenSura Mio product line through their website or by calling 1-855-605-7588. They also offer a tool called BodyCheck that evaluates your body profile and recommends products based on your stoma shape, skin contours, and lifestyle. You can email [email protected] with questions. Hollister and ConvaTec have similar sample programs on their websites. In all cases, you fill out a short form describing your current setup and what you’d like to try, and samples arrive by mail within a week or two.
Pharmacies and Local Stores
Some national pharmacy chains and local home medical equipment stores carry a limited selection of ostomy supplies. The reality, though, is that most brick-and-mortar pharmacies stock very few ostomy products compared to what’s available online. You might find a basic one-piece pouch, but the specific brand, size, or flange style you need may not be on the shelf.
If you need supplies the same day, calling ahead saves a wasted trip. Ask the pharmacy if they carry ostomy pouches and what brands they stock. Independent home health supply stores in your area are more likely to carry a broader selection than a chain drugstore.
Insurance Coverage and Prescriptions
You don’t need a prescription to buy colostomy bags out of pocket. However, if you want insurance to cover the cost, a prescription (called a “standard written order” in Medicare terms) is required.
Medicare covers ostomy supplies under its Prosthetic Device benefit (Part B) for anyone with a permanent or long-duration ostomy. “Permanence” in Medicare’s definition means a condition of long and indefinite duration, which your doctor confirms. The treating physician must document medical necessity, and the supplier submits claims with proper coding. Medicare sets usual maximum quantities per month, though your doctor can request higher amounts if your medical records support the need.
One important detail: if you’re currently receiving home health services through Medicare, ostomy supplies are bundled into your home health payment. That means the home health agency is responsible for providing them, and they aren’t separately billable. If your home health agency isn’t supplying what you need, raise it with them directly.
Private insurance plans vary. Most cover ostomy supplies to some degree, but copays, preferred suppliers, and quantity limits differ by plan. Call the number on your insurance card and ask specifically about durable medical equipment coverage for ostomy supplies.
Getting Professionally Fitted
Buying the right colostomy bag matters more than buying it from the right place. A poorly fitting pouch leads to leaks, skin irritation, and frustration. The best resource for getting properly fitted is a Wound, Ostomy and Continence Nurse, commonly called a WOC nurse or WOCN.
These are nurses with specialized training in ostomy care. They measure your stoma, assess your skin and body contours, and recommend specific products that fit your anatomy. Many hospitals assign a WOC nurse before discharge after ostomy surgery, but you can also find one independently. The United Ostomy Associations of America maintains a searchable directory at ostomy.org where you can locate a WOC nurse or an Ostomy Management Specialist (OMS) in your area by state.
If you’ve been managing your ostomy for a while but are dealing with persistent leaks or skin problems, a single visit with a WOC nurse can sometimes solve issues you’ve been struggling with for months. They may suggest a different pouch shape, a convex wafer, or a barrier ring you hadn’t considered.
Reducing Costs Without Insurance
Ostomy supplies add up. A month’s worth of pouches, wafers, and accessories can run anywhere from $100 to over $300 depending on the system you use and how frequently you change it. If you’re uninsured or underinsured, several strategies can bring costs down significantly.
First, contact manufacturers directly. Beyond free samples, companies like Coloplast, Hollister, and ConvaTec sometimes have patient assistance programs or can connect you with discount pricing. Second, the lower-cost specialty suppliers listed by UOAA (Best Buy Ostomy Supplies, Medical Monks, and others) often beat standard retail pricing. Third, local ostomy support groups sometimes coordinate supply exchanges where people donate unused, unopened products they no longer need. Your nearest UOAA-affiliated support group is a good place to ask.
Some nonprofit organizations collect and redistribute donated ostomy supplies to people who can’t afford them. Availability varies by region, but searching “ostomy supply donation” along with your state is a reasonable starting point. Hospital social workers can also connect you with local assistance programs you might not find on your own.
Keeping Emergency Supplies on Hand
Running out of colostomy bags unexpectedly is stressful, and same-day access isn’t always easy. Most ostomy nurses recommend keeping at least a two-week backup supply at home at all times, stored separately from your regular stock so you don’t accidentally dip into it.
If you do run out, your options for immediate help include calling your ostomy supply company to request expedited shipping, visiting a local home medical equipment store, or contacting your hospital’s ostomy clinic. Emergency rooms stock basic ostomy supplies for acute situations, but the selection is minimal and it’s not a practical routine source. Planning ahead with auto-shipment from your supplier is the simplest way to avoid gaps.
