Other specified rickettsioses
ICD-10 A79.89 is a billable code used to indicate a diagnosis of other specified rickettsioses.
Rickettsioses are a group of infectious diseases caused by bacteria of the genus Rickettsia, which are primarily transmitted to humans through the bites of infected arthropods, such as ticks, fleas, and lice. The clinical manifestations of rickettsial infections can vary widely, ranging from mild febrile illnesses to severe, life-threatening conditions. Symptoms often include fever, headache, rash, and myalgia, but can also involve more severe complications such as organ failure or hemorrhagic manifestations. The term 'Other specified rickettsioses' encompasses rickettsial diseases that do not fall under the more commonly recognized categories, such as Rocky Mountain spotted fever or typhus. This code is particularly relevant for cases where the specific rickettsial agent is identified, but does not correspond to the established codes for the more prevalent rickettsial diseases. Travel-related infections are significant, as many rickettsial diseases are endemic to specific geographic regions, and travelers may be at risk of exposure. Accurate diagnosis and coding are essential for appropriate treatment and epidemiological tracking.
Detailed clinical notes including travel history, symptoms, and laboratory results.
Patients presenting with fever and rash after travel to endemic areas.
Ensure that the specific rickettsial species is documented to support the use of A79.89.
Comprehensive patient history and symptom assessment.
Patients with unexplained febrile illness and potential exposure to vectors.
Consider differential diagnoses and document any relevant travel history.
Used when testing for rickettsial infections is performed.
Document the reason for testing and the clinical findings.
Infectious disease specialists may require more detailed documentation.
Document the patient's symptoms, travel history, and any laboratory results that confirm a rickettsial infection. Be specific about the rickettsial species if known.
