What is this code?
ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Certain infectious and parasitic diseases (A00-B99).
đź“‹Clinical overview
This ICD-10 code is commonly used when documentation describes cholera. The most accurate code depends on whether the chart identifies Vibrio cholerae 01 biovar cholerae, Vibrio cholerae 01 biovar eltor, or leaves the cholera type unspecified.
When is it used?
- May be used when a clinician documents cholera in a patient's medical record.
- May appear in hospital records, claims, referrals, and clinical documentation.
- This code may act more like a grouping or parent code, so a more specific child code may be used in final documentation when available.
What it does not mean
- A code alone does not explain severity, treatment plan, or outcome.
- A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
- This entry may represent a broader category rather than the most specific billable code.
đź©şClinical context
When commonly used
- Emergency, inpatient, infectious-disease, travel-medicine, public-health, and follow-up documentation where acute cholera or recent cholera treatment is part of the active assessment.
- Coding and utilization-review workflows where strain detail changes final code specificity and where the chart distinguishes confirmed cholera from other causes of severe infectious diarrhea.
Common management context
- Evaluation often includes assessment of profuse watery diarrhea, dehydration severity, travel or outbreak exposure history, stool-testing review, rapid fluid replacement planning, electrolyte monitoring, and public-health reporting context.
- Documentation usually becomes more specific when the chart identifies the Vibrio cholerae strain rather than leaving cholera type unspecified.
- Specialist context already linked on this page includes Infectious Disease Specialist, General Physician.
🔍Key distinctions
Important notes
- This ICD-10 family captures diagnosed cholera and is distinct from other bacterial or viral gastroenteritis because the specific Vibrio cholerae infection drives code selection.
- Strain detail matters across this branch, with biovar cholerae and biovar eltor coded separately from unspecified cholera.
- This parent page groups cholera diagnoses, so the final billable code usually depends on whether the chart identifies Vibrio cholerae 01 biovar cholerae, Vibrio cholerae 01 biovar eltor, or leaves the cholera type unspecified.
- Documentation that describes cholera is coded differently from other infectious diarrhea, noninfectious gastroenteritis, or nonspecific dehydration because the diagnosed Vibrio cholerae infection drives final code selection.
