ICD-10 Code K94.23 – Gastrostomy malfunction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K94.23 – Gastrostomy malfunction
What it is
K94.23 identifies a problem with a gastrostomy tube or stoma that is not working as intended. Use it when the device or tract has malfunctioned, causing feeding or access issues.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include tube blockage, leakage, dislodgement, poor function, or difficulty using the gastrostomy for feeding or medication delivery.
When to use this code
Use K94.23 when the record states gastrostomy malfunction, such as a clogged, displaced, leaking, or otherwise nonfunctioning tube. It also fits when the provider documents malfunction of the gastrostomy site or device without a more specific complication code.
Choose this code based on the clinician’s wording and the documented problem. If the note specifies a different complication, such as infection or mechanical complication of another device, code that condition instead.
Do not use for
Do not use K94.23 for routine gastrostomy care, status of a tube without malfunction, or general feeding difficulty without a documented device problem. Check documentation if the issue is unrelated to the gastrostomy itself.
Coding tip
Code the exact complication documented; if the record only says “PEG issue” or “tube problem,” query for clarification.
