Other spotted fevers

This code represents various rickettsial infections characterized by fever and a rash, excluding specific conditions like Rocky Mountain spotted fever or Boutonneuse fever. These are typically vector-borne diseases caused by different species of Rickettsia bacteria, often transmitted by ticks or mites. The clinical presentation can vary but generally includes acute onset of fever, headache, myalgia, and a maculopapular or petechial rash.

Use this code when documentation specifies a spotted fever rickettsiosis that is not otherwise classified to a more specific ICD-10-CM code. This applies to diagnoses such as Pacific Coast tick fever, Astrakhan fever, or other unspecified spotted fevers. Supporting documentation should clearly indicate a diagnosis of a spotted fever rickettsiosis and rule out more specific types.

• Ensure the physician's documentation explicitly states "other spotted fever" or a specific spotted fever not separately classified.
• Do not use this code if the documentation specifies Rocky Mountain spotted fever (A77.0) or Boutonneuse fever (A77.1).
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
