    ICD-10-CM Code For Cholera: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group A00 includes cholera due to Vibrio cholerae, covering acute enteric infections characterized by profuse watery diarrhea and related complications such as dehydration and electrolyte imbalance. These ICD-10-CM diagnosis codes are used to document acute intestinal infection presentations, severity of dehydration, and any complications or specified organism involvement relevant to management and reporting. Accurate coding within the ICD-10-CM A00 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM A00: Cholera Overview

    The diagnoses in this group represent cholera infections caused by Vibrio cholerae that primarily affect the intestinal tract and cause profuse watery diarrhea and dehydration. They target acute intestinal infectious disease processes and related fluid and electrolyte disturbances. Accurate coding matters for appropriate clinical documentation, public health reporting, and reimbursement for services tied to disease severity and complications.

    When to Use

    Use a code from this group when a patient is diagnosed with cholera based on clinical presentation, laboratory confirmation, or epidemiologic evidence of Vibrio cholerae infection. Assign the specific code that reflects organism confirmation and any associated dehydration or other complications documented in the medical record.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with sudden onset profuse watery diarrhea, vomiting, severe dehydration, and signs of hypovolemic shock after recent travel to a region with known cholera outbreaks. Stool culture or rapid test confirms toxigenic Vibrio cholerae, and the clinician assigns an acute infectious diagnosis reflecting cholera with dehydration requiring urgent rehydration and possible antibiotics. Typical codes: A00.0, A00.1
    • A pediatric patient in an outpatient clinic has a history of several days of watery, non-bloody diarrhea without systemic toxicity after household exposure to a confirmed case; symptoms are self-limited and managed with oral rehydration at home. Because the clinical picture is consistent with cholera without severe dehydration and diagnostic confirmation may be pending or clinical, the coder assigns a diagnosis indicating cholera without mention of severe complications. Typical codes: A00.9
    • An older adult is hospitalized with acute cholera who develops severe dehydration complicated by acute renal failure and requires intravenous fluids and monitoring; laboratory testing identifies toxigenic Vibrio cholerae on stool testing. The hospital record documents cholera as the underlying infectious cause contributing to the acute complications, so an acute cholera code specifying severity is used alongside codes for the complications. Typical codes: A00.0, A00.1
