Shigellosis, unspecified

This code represents an acute bacterial infection of the intestinal tract caused by Shigella species, characterized by diarrhea, fever, and abdominal cramps. It specifically denotes shigellosis where the causative organism or specific type is not documented.

Apply this code when documentation confirms a diagnosis of shigellosis but lacks specificity regarding the Shigella species (e.g., S. dysenteriae, S. flexneri, S. boydii, S. sonnei). This is appropriate when laboratory confirmation identifies Shigella but does not speciate, or when a clinical diagnosis of shigellosis is made without further detail.

• Do not use if a specific Shigella species is identified; instead, code to the more specific category (004.0-004.8).
• Always review microbiology reports for definitive organism identification.
• Sequence as the primary diagnosis when shigellosis is the reason for the encounter.
