Shigella sonnei

This code identifies an intestinal infection caused by Shigella sonnei, a specific serotype of the Shigella bacterium. It represents bacillary dysentery or shigellosis, characterized by symptoms such as fever, abdominal cramps, and watery or bloody diarrhea.

Use this code when documentation specifically identifies Shigella sonnei as the causative agent of shigellosis. This often follows laboratory confirmation via stool culture. Apply when the patient presents with acute gastroenteritis symptoms and the pathogen is confirmed.

• Ensure the documentation specifies Shigella sonnei rather than a general Shigella infection or another bacterial enteritis.
• Do not use this code for other types of bacterial food poisoning or viral gastroenteritis.
• Consider additional codes for dehydration (e.g., 276.51) or other complications if documented.
