A06 — Amebiasis
A06 is a non-billable header ICD-10-CM code for amebiasis. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- other protozoal intestinal diseases (A07.-)
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
Includes
Conditions this code covers.
- infection due to Entamoeba histolytica
Other codes that can never be billed with A06
These codes carry an Excludes1 note pointing at A06. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A06 alone.
Risk adjustment
A06 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code to one of these instead A06
10 child codes. Green means billable.
