021.1
ICD-9-CMThis code represents tularemia, an infectious disease caused by the bacterium Francisella tularensis, specifically when the infection manifests primarily in the gastrointestinal tract. This form typically results from ingestion of contaminated food or water, leading to symptoms such as abdominal pain, vomiting, diarrhea, and pharyngitis.
Apply this code when documentation specifies tularemia with a predominant enteric presentation, often characterized by gastrointestinal symptoms following oral exposure. Supporting documentation should indicate a confirmed diagnosis of tularemia and describe the primary involvement of the digestive system.
