A06.3

What This Code Means

An ameboma is a tumor-like mass in the intestines caused by a parasitic infection from Entamoeba histolytica. This condition develops when the parasite invades the intestinal wall and causes chronic inflammation and tissue damage.

Coding Tips

• •Verify that the ameboma is specifically located in the intestine, as amebomas can occur in other sites (liver, brain) which have different codes
• •Ensure the diagnosis is confirmed as amebic in origin rather than other causes of intestinal masses, and document the specific location (colon, cecum, etc.) if available for greater specificity
