ICD-10 Code A07.0 – Balantidiasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A07.0 – Balantidiasis
What it is
Balantidiasis is an intestinal infection caused by the protozoan Balantidium coli. It is coded when documentation identifies this specific parasitic disease.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include diarrhea, abdominal pain, and dysentery-like illness, but presentation may range from mild to severe.
When to use this code
Use A07.0 when the provider documents balantidiasis, balantidial colitis, or infection due to Balantidium coli. Apply it for confirmed parasitic intestinal disease, not for nonspecific diarrhea without a documented cause. If the record is unclear, check documentation before coding.
Do not use for
Do not use this code for diarrhea, colitis, or dysentery without documented balantidiasis. If another infectious agent is named, code the documented condition instead.
Coding tip
Look for the organism name or a direct diagnosis of balantidiasis before assigning A07.0.
