Typhus fever, unspecified

This code represents a systemic infectious disease caused by Rickettsia bacteria, characterized by fever, headache, and a rash, when the specific type of typhus (e.g., epidemic, murine, scrub) is not documented. It indicates a generalized typhus infection without further specification of its origin or strain.

Use this code when the medical record clearly states a diagnosis of "typhus fever" but lacks any further detail regarding the specific type. Documentation supporting its use would include physician notes indicating typhus without specifying epidemic, murine, or scrub typhus, or when laboratory results confirm Rickettsia infection but the specific species is not identified.

• Avoid using this code if the documentation specifies a particular type of typhus; instead, use the more specific code.
• Query the provider for clarification if "typhus fever" is documented without further detail, to determine if a more specific code can be assigned.
• This code should be used as a last resort when no other specific typhus code can be supported by the available clinical documentation.
