2025 ICD-10-CM code A00.9
(Active) Effective Date: N/A Infectious and parasitic diseases - Intestinal infectious diseases Certain infectious and parasitic diseases Feed
This code represents a diagnosis of cholera without specification of the causative Vibrio cholerae strain.
Medical necessity for treatment is established by the diagnosis of cholera, with severity influencing the choice between oral and intravenous rehydration and the need for antibiotics.
Clinicians should diagnose cholera based on symptoms, patient history, and laboratory confirmation of Vibrio cholerae in stool samples. Treatment typically involves rehydration therapy (oral or intravenous) and, in severe cases, antibiotics.
In simple words: Cholera is a bacterial infection of the gut, usually spread through contaminated food or water. It causes severe diarrhea and vomiting, which can lead to dehydration.This particular code is used when the doctor doesn't know the exact type of cholera bacteria causing the illness.
Cholera is an infectious disease caused by the bacterium Vibrio cholerae. It primarily affects the gastrointestinal system, leading to symptoms such as severe watery diarrhea, vomiting, and leg cramps. In severe cases, extreme dehydration, shock, and even death can occur.This code (A00.9) is used when the specific strain of Vibrio cholerae is not documented.
Example 1: A patient presents with profuse watery diarrhea, vomiting, and leg cramps after consuming contaminated water.Lab tests confirm Vibrio cholerae, but the specific strain is not identified. A00.9 is used., A patient returning from an area with a cholera outbreak develops severe dehydration and shock. While cholera is suspected, lab results are pending. A00.9 may be used provisionally., A patient experiences mild diarrhea after eating raw shellfish. Vibrio cholerae is detected, but the strain is not specified, and the symptoms do not progress to severe cholera. A00.9 is applied.
Documentation should include signs and symptoms, travel history, laboratory results confirming Vibrio cholerae (if available), and details of rehydration and antibiotic treatment.
