Spotted fever due to Rickettsia australis

This code identifies a specific rickettsial infection characterized by fever and a rash, caused by the bacterium Rickettsia australis. It is a form of spotted fever, distinct from other rickettsial diseases.

Apply this code when documentation explicitly states a diagnosis of spotted fever due to Rickettsia australis. Confirmation typically relies on laboratory testing, such as serology or PCR, identifying the specific pathogen.

• Ensure the documentation clearly specifies Rickettsia australis as the causative agent, not just general "spotted fever."
• Do not confuse with other rickettsial infections like Rocky Mountain Spotted Fever (due to Rickettsia rickettsii) or other forms of typhus.
• Review for any associated manifestations or complications that may require additional coding.
