A00.9

What This Code Means

Cholera is a serious bacterial infection that causes severe diarrhea and dehydration, but the specific type or form of the disease is not documented. This code is used when a patient has cholera but the medical record doesn't specify whether it's the classic form, El Tor biotype, or other variants.

Coding Tips

• •Use A00.9 only when the documentation does not specify the type of cholera; if the specific biotype (classic A00.0 or El Tor A00.1) is documented, use the more specific code instead
• •Cholera is a reportable disease in most jurisdictions, so ensure proper public health notification procedures are followed when this code is assigned
