Understanding Cholera ICD-11 Code 1A00

Cholera is a severe, acute intestinal infection classified under ICD-11 code 1A00. It is caused by toxigenic strains of the bacterium Vibrio cholerae and has the potential to occur in outbreaks and epidemics, particularly in areas with limited access to clean water.

The disease is characterized by sudden onset of profuse watery diarrhoea and vomiting. These symptoms result in rapid loss of fluids and electrolytes. If untreated, cholera can quickly progress to hypovolemic shock, metabolic acidosis, and death.

Key Symptoms of Cholera

Symptoms can develop within hours to days after exposure. The severity depends on the volume of fluid loss and the speed of rehydration.

What Causes Cholera

Cholera is transmitted through ingestion of food or water contaminated with toxigenic strains of Vibrio cholerae. The organisms produce cholera toxin, which disrupts intestinal fluid regulation and causes massive secretion of water into the bowel.

Managing Cholera Infections

Prompt treatment is essential to prevent complications. The cornerstone of cholera management is rapid rehydration to restore circulating volume and correct electrolyte imbalance.

Are Cholera ICD codes billable

ICD-11 code 1A00 is a billable diagnosis code when supported by appropriate clinical documentation. It may be used for inpatient and outpatient encounters involving confirmed or clinically suspected cholera.

Documentation should clearly describe acute watery diarrhoea, associated vomiting, dehydration status, and laboratory confirmation when available to support accurate coding and reimbursement.

Coding and Documenting Cholera

Accurate coding is important for surveillance, outbreak control, and healthcare reporting. When cholera is confirmed, documentation may include the identified Vibrio cholerae serogroup to improve clinical specificity.

Seeking Urgent Medical Care for Cholera Symptoms

Any individual experiencing sudden onset of severe watery diarrhoea, especially when accompanied by vomiting or signs of dehydration, requires immediate medical evaluation. Early recognition and rapid fluid replacement are critical to preventing life threatening complications and reducing mortality.
