ICD-10 Code A06.9 – Amebiasis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A06.9 – Amebiasis, unspecified
What it is
A06.9 identifies amebiasis when the record does not specify the site or type. Use it for infection caused by Entamoeba histolytica when documentation only states amebiasis.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include diarrhea, abdominal pain, or dysentery, but the chart must support a parasitic intestinal infection.
When to use this code
Use A06.9 when the clinician documents amebiasis without further detail, such as intestinal, hepatic, or other specified involvement. It also fits when the note confirms amebiasis but does not identify the manifestation. If the record names a specific site or complication, code that more specific diagnosis instead.
Do not use for
Do not use this code for nonspecific diarrhea, colitis, or abdominal pain without documented amebiasis. If the provider specifies another parasitic infection or an amebic condition with a defined site, select the appropriate code.
Coding tip
Check the assessment for a documented amebic diagnosis; unspecified codes should reflect incomplete clinical detail, not missing review.
