Amebiasis (A06) ICD-10-CM

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.

About the A06 Code Range
Amebiasis is an infection with amebae. It often causes no symptoms but can cause mild, long-lasting diarrhea or severe diarrhea.
The intestinal subdivisions distinguish acute dysentery in A06.0, chronic infection in A06.1, and other intestinal forms in A06.2 and A06.3. Other codes distinguish abscesses in the liver, lung, or brain, skin infection, and infection at other sites. Within other sites, A06.81 names bladder infection, A06.82 names other genitourinary infections, and A06.89 names other infections. A06.9 is amebiasis without a specified form.
