About A06

A06 is the ICD-10-CM diagnosis code for amebiasis. It belongs to block A00-A09 (intestinal infectious diseases) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: A06.0 (dysentery), A06.1 (amebiasis), A06.2 (colitis), A06.3 (intestine), A06.4 (abscess), A06.5 (abscess), A06.6 (abscess), A06.7 (amebiasis) and 2 more.

Don't report A06 together with the conditions in its Excludes1 note: other protozoal intestinal diseases (A07.-).

The conditions in its Excludes2 note aren't part of A06, but may be coded alongside it if the patient has both: acanthamebiasis (B60.1-) and Naegleriasis (B60.2).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
