Cholera, unspecified

This code represents a diagnosis of cholera without further specification of the causative organism or clinical manifestation. Cholera is an acute diarrheal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae, leading to severe dehydration.

Use this code when the medical record documents a diagnosis of cholera, but lacks specific details regarding the Vibrio cholerae serogroup (e.g., O1 or O139) or the specific clinical form (e.g., classical, El Tor). This code is appropriate when the physician's documentation simply states "cholera" without further elaboration.

• Avoid using this code if the specific Vibrio cholerae serogroup is documented; instead, use a more specific code from category 001.0-001.1.
• Ensure documentation supports a confirmed or suspected diagnosis of cholera, not just general gastroenteritis.
• Sequence this as the principal diagnosis if it is the primary reason for the encounter.
