Amebiasis (A06)
The ICD-10 code A06 covers amebiasis, an infection caused by the parasite Entamoeba histolytica. These codes are used to identify various forms of this parasitic disease affecting the intestines and other body sites, including acute and chronic intestinal infections, abscesses, and less common manifestations.
The section includes specific codes like A06.0 for acute amebic dysentery, also known as amebic colitis or protozoal enteritis, which is an intestinal infection causing inflammation and diarrhea. A06.1 captures chronic intestinal amebiasis, reflecting longer-term infections. Other codes address complications such as amebic liver abscess (A06.4), lung abscess (A06.5), brain abscess (A06.6), and skin involvement (A06.7). Additionally, codes like A06.81 and A06.82 specify amebic infections of the urinary and genital tracts. The unspecified amebiasis code A06.9 is used when the exact site or type of amebic infection is not documented. These codes help healthcare providers document and treat the disease accurately, using terms like amebic dysentery, ameboma, and amebic abscess related to distinct ICD-10 diagnoses.

Instructional Notations
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- infection due to Entamoeba histolytica
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- other protozoal intestinal diseases A07
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Amebiasis
Infection with any of various amebae. It is an asymptomatic carrier state in most individuals, but diseases ranging from chronic, mild diarrhea to fulminant dysentery may occur.
Dysentery, Amebic
DYSENTERY caused by intestinal amebic infection, chiefly with ENTAMOEBA HISTOLYTICA. This condition may be associated with amebic infection of the LIVER and other distant sites.
Liver Abscess, Amebic
Single or multiple areas of PUS due to infection by any ameboid protozoa (AMEBIASIS). A common form is caused by the ingestion of ENTAMOEBA HISTOLYTICA.
