In simple words: This code refers to a diagnosis of tularemia without any further details about the specific way it's affecting the patient. Tularemia is an infection you can get from animals, mostly rabbits and rodents, often through insect bites.

Tularemia, also known as rabbit fever or deerfly fever, is a rare bacterial infection caused by Francisella tularensis.This code indicates that the provider has not specified the clinical presentation of tularemia (e.g., ulceroglandular, glandular, oculoglandular, pneumonic, oropharyngeal, typhoidal).

Example 1: A hunter presents with fever, chills, and an ulcer on their hand after skinning a rabbit.Laboratory tests confirm tularemia, but the specific type is not documented. A21.9 is used., A patient develops pneumonia after inhaling contaminated dust while working on a farm.Tularemia is confirmed, but the clinical type isn't specified in the record. A21.9 is applicable., A child has swollen lymph nodes and a fever after being bitten by a tick. Tularemia is diagnosed through serologic testing, but the specific form is not documented. A21.9 is the appropriate code.

Documentation should include details of the patient's symptoms, exposure history (e.g., animal contact, insect bites), laboratory results (e.g., blood cultures, serology), and clinical findings (e.g., presence of ulcers, swollen lymph nodes).
