Gastrointestinal tularemia

This code represents tularemia that primarily affects the gastrointestinal tract. It is an infectious disease caused by the bacterium Francisella tularensis, manifesting with symptoms such as abdominal pain, vomiting, diarrhea, and potentially gastrointestinal ulceration or lymphadenopathy.

Use this code when documentation specifies a diagnosis of tularemia with a clear indication of gastrointestinal involvement, such as enteritis, pharyngitis, or mesenteric lymphadenitis caused by F. tularensis. This code is supported by positive bacterial cultures, serological tests, or clinical findings consistent with gastrointestinal tularemia.

• Differentiate from other forms of tularemia (e.g., ulceroglandular, oculoglandular) which have distinct codes.
• Ensure documentation explicitly links Francisella tularensis to the gastrointestinal symptoms.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter, followed by any associated manifestations.
