Code Description

ICD-10 A21.2 is a billable code used to indicate a diagnosis of tularaemia.

Key Diagnostic Point:

Tularaemia is an infectious disease caused by the bacterium Francisella tularensis, which is primarily a zoonotic pathogen. It is transmitted to humans through direct contact with infected animals, bites from infected insects, or inhalation of contaminated aerosols. Common reservoirs include rabbits, hares, and rodents, with ticks and deer flies serving as primary vectors. The disease can manifest in various forms, including ulceroglandular, glandular, oculoglandular, or pneumonic, depending on the route of infection. Symptoms may include fever, chills, headache, muscle aches, and swollen lymph nodes, with the potential for severe complications if not treated promptly. Public health considerations are critical, as tularaemia is classified as a potential bioterrorism agent due to its infectious nature and ability to be aerosolized. Surveillance and control measures are essential to prevent outbreaks, particularly in areas where the disease is endemic. Vaccination is not widely available, making awareness and preventive measures vital for at-risk populations.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of clinical presentations requiring accurate identification
  • Potential for misdiagnosis with other zoonotic infections
  • Need for detailed documentation of exposure history
  • Variability in symptomatology based on transmission route

Audit Risk Factors

  • Inadequate documentation of exposure history
  • Failure to specify the clinical form of tularaemia
  • Misclassification of symptoms or related conditions
  • Lack of supporting lab results for diagnosis
