About Two-Piece Ostomy Pouches
In a two-piece ostomy system, the skin barrier stays on the body while the pouch attaches to it through a coupling ring called the flange. Pouches can be changed without removing the barrier. This collection holds the pouch half of that system, in drainable, closed-end and urostomy styles from Coloplast, Hollister and ConvaTec, and belongs to our Ostomy Supplies category beside the matching skin barriers and wafers.
Flange size is the first thing to match. It is the diameter of the coupling ring, usually listed in millimeters or inches, and the pouch flange must be the same size and from the same product line as your barrier. A pouch from one manufacturer will not snap onto another manufacturer's barrier, and different lines within one brand may use different coupling types, such as mechanical rings or adhesive coupling.
Next choose drainable or closed. Drainable pouches have an outlet for emptying; closed pouches are replaced when full; urostomy pouches have a tap for urine and can connect to a night bag. Other details to compare include pouch length, transparent or opaque film, and whether a filter is built in.
To reorder, copy the REF number and flange size from your current pouch box.
Frequently asked questions
How do I match a two-piece pouch to my barrier?
Check the flange size printed on your barrier box and choose a pouch with the same flange size from the same product line. Coupling systems are not interchangeable between manufacturers. After that, choose drainable, closed or urostomy style, pouch length, and opaque or transparent film based on what your ostomy nurse or clinician recommended.
Are two-piece ostomy pouches covered by insurance?
Two-piece pouches typically have HCPCS codes, which are displayed on each product page for reference. Coverage, allowed monthly quantities and prescription requirements depend on your payer and plan. ArmadaMeds is a retailer, not a billing provider, and cannot promise reimbursement, so check the details with your plan before ordering.
How do I reorder the same two-piece pouch?
Use the REF number from your current box, along with the flange size. Pouches are generally sold by the box, and each flange size and style has its own item number. Confirming both the REF number and the flange size keeps your pouches compatible with the barriers you already have.
