Questions About A06Overview

What is the ICD-10 code for amebiasis?

A06 is the ICD-10-CM category for amebiasis, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is A06 (Amebiasis) a billable code?

No. This is a category header that groups the codes for amebiasis, and headers cannot be submitted on claims. Claims for amebiasis need a more specific code from this category, such as A06.0, A06.1, and A06.2.

Can A06 be reported with a code from A07?

Not as a rule. The Excludes1 note on A06 lists "other protozoal intestinal diseases (A07.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
