Rickettsiosis, unspecified

This code represents an infection caused by Rickettsia bacteria, where the specific type of rickettsiosis is not identified. These infections are typically transmitted by arthropod vectors like ticks, fleas, or lice, and can manifest with fever, headache, and rash. It indicates a confirmed or suspected rickettsial disease without further specification of the causative agent or clinical syndrome.

Use this code when documentation confirms a diagnosis of rickettsiosis but lacks specificity regarding the particular Rickettsia species or the distinct clinical presentation (e.g., Rocky Mountain spotted fever, typhus). This code is appropriate when the physician's diagnosis is simply "rickettsiosis" or "rickettsial infection" without further detail.

• Avoid using this code if a more specific rickettsial infection (e.g., Rocky Mountain spotted fever, typhus) is documented.
• Query the provider for more specific documentation if possible to allow for a more precise code assignment.
• This code should be sequenced as the primary diagnosis when it is the reason for the encounter.
