ICD-10 Code K94.22 – Gastrostomy Infection (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K94.22 – Gastrostomy infection
What it is
K94.22 identifies an infection involving a gastrostomy site or gastrostomy tube. Use it when the record clearly documents infection related to the feeding access, not just routine tube care.
Clinical signs
Clinical features may include redness, swelling, drainage, pain, or tenderness around the gastrostomy site. Fever or local purulent discharge may also be documented; clinical features vary, refer to documentation.
When to use this code
Use K94.22 when the provider documents gastrostomy infection, infected gastrostomy stoma, or infection of the gastrostomy tube site. It is appropriate when the infection is the reason for evaluation, treatment, or ongoing care. If the note only mentions irritation, leakage, or routine site care, check documentation before assigning this code.
Do not use for
Do not use this code for a noninfectious gastrostomy complication such as mechanical malfunction or displacement. Do not apply it when infection is not documented or when the problem is unrelated to the gastrostomy site.
Coding tip
Code K94.22 only when the infection is clearly linked to the gastrostomy site or tube in the medical record.
