Shigellosis due to Shigella boydii

This code identifies an acute bacterial infection of the intestines caused specifically by the bacterium Shigella boydii. Patients typically present with symptoms such as severe diarrhea, fever, abdominal cramps, and tenesmus, often accompanied by blood or mucus in the stool. This condition is a form of dysentery.

This code is appropriate when documentation confirms a diagnosis of shigellosis and laboratory testing or clinical suspicion specifically identifies Shigella boydii as the causative agent. It should be used for confirmed infections where the specific serogroup of Shigella is known.

• Always ensure documentation specifies Shigella boydii as the pathogen; otherwise, use a less specific shigellosis code.
• Do not confuse with other Shigella species (e.g., Shigella dysenteriae, Shigella flexneri, Shigella sonnei), which have their own distinct codes.
• Code any associated manifestations, such as dehydration (E86.0), as secondary diagnoses.
