ICD-10 Code A06.3 – Ameboma of intestine (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A06.3 – Ameboma of intestine
What it is
A06.3 identifies ameboma, a localized inflammatory mass in the intestine caused by Entamoeba histolytica. Use it when documentation specifically names an ameboma or amebic granuloma.
Clinical signs
Clinical features vary; refer to documentation. Typical references describe a mass-like intestinal lesion that may mimic a tumor and can be associated with abdominal pain, bowel symptoms, or obstruction.
When to use this code
Use A06.3 when the provider documents ameboma of the intestine as the diagnosis. It fits confirmed or clinically stated intestinal ameboma, including cases described as an amebic mass or granuloma. If the record only says intestinal amebiasis without a mass, check documentation for a more specific code.
Do not use for
Do not use this code for nonspecific diarrhea, colitis, or intestinal infection without mention of ameboma. If the mass is not attributed to Entamoeba histolytica, check documentation.
Coding tip
Look for the exact term “ameboma” or “amebic granuloma” in the assessment before assigning A06.3.
