Typhoid fever

This code represents an acute systemic infection caused by Salmonella typhi, characterized by sustained fever, headache, malaise, anorexia, and often a rash. It is a severe bacterial infection primarily affecting the gastrointestinal tract and reticuloendothelial system.

Use this code for confirmed cases of typhoid fever, typically diagnosed via blood, stool, or bone marrow cultures. Documentation should clearly indicate the presence of the disease and not merely a carrier state or exposure.

• Differentiate from paratyphoid fever (002.1) and other salmonella infections (003.x).
• Ensure documentation specifies the organism S. typhi for accurate coding.
• Code any associated complications, such as intestinal hemorrhage or perforation, as secondary diagnoses.
