About G-Tubes & Balloon Buttons
A gastrostomy tube passes through a stoma into the stomach and is used for tube feeding and venting. Low-profile balloon buttons sit close to the skin and connect to a separate extension set when in use, while standard G-tubes have a longer external tube. This collection covers both, plus the extension sets and replacement components used with them, from Applied Medical Tech, Halyard Health and others. It is part of Enteral Feeding Supplies.
Two measurements define a replacement button. French size is the diameter of the stem, and stoma length, in centimeters, is the depth of the tract from skin to stomach wall. Both are set as specified by your clinician, who will measure the stoma length when fitting a new button. Balloon volume and the recommended fill are printed on the device.
Extension sets must match the button brand, since each manufacturer uses its own locking connection, and many now have an ENFit port at the feeding end. When reordering, read the French size and stoma length printed on the button, or use the REF number from the packaging. Extension sets are often sold in multi-packs, as listed.
Frequently asked questions
How do I order the right replacement button size?
A button is sized by French size and stoma length, both printed on the device and its packaging. Reorder the same size unless your clinician has measured and specified a change, since stoma length can shift over time. Balloon buttons and non-balloon buttons are not interchangeable without a clinician's direction.
Are G-tubes and balloon buttons covered by insurance?
Gastrostomy tubes are often covered with a prescription, commonly under HCPCS codes B4087 for a standard tube and B4088 for a low-profile tube. Those codes are shown for reference only. Replacement frequency, coverage of extension sets and documentation requirements depend on your payer and plan.
How do I reorder the same button or extension set?
Use the REF number from the packaging or the French size and stoma length on the button itself. For extension sets, match the button brand and connector type, then check whether the listing is a single set or a multi-pack. Keeping that number on file makes each reorder exact.
