Shigellosis, unspecified

This code signifies an acute bacterial infection of the intestinal tract caused by Shigella species, where the specific type of Shigella is not documented. It typically presents with symptoms such as diarrhea (often bloody), fever, abdominal cramps, and tenesmus. The infection can range from mild to severe.

Use this code when the medical record confirms a diagnosis of shigellosis, but the specific Shigella serogroup (e.g., Shigella dysenteriae, S. flexneri, S. boydii, S. sonnei) is not identified or specified. Documentation supporting this code would include a physician's diagnosis of shigellosis without further microbiological speciation.

• Only use this code when the specific Shigella species is truly unknown or unstated in the medical record.
• If the specific Shigella species is identified, use the more precise codes within the A03 category (e.g., A03.0 for Shigella dysenteriae).
• Always review microbiology reports and physician documentation for any mention of the specific Shigella species to ensure the highest level of specificity.
