Yes, two-piece ostomy bags require a compatible separate wafer or skin barrier to attach to the body. In a two-piece ostomy system, the wafer attaches to the skin around the stoma, while the pouch connects to the wafer through a compatible flange, coupling, or adhesive connection to collect stoma output.
The pouch and wafer must be compatible with the same product system. Product specifications should be reviewed carefully to confirm brand compatibility, flange or coupling size, opening size, barrier style, pouch type, closure type, and stoma compatibility before ordering.
