Bartonellosis

This code represents Bartonellosis, a group of infectious diseases caused by bacteria of the genus Bartonella. These infections can manifest with a variety of symptoms, including fever, anemia, skin lesions (e.g., verruga peruana), and sometimes more severe systemic involvement affecting organs like the heart or brain.

Use this code when documentation specifies a diagnosis of Bartonellosis, such as Carrion's disease (Oroya fever or verruga peruana), trench fever, or cat scratch disease (when the causative agent is Bartonella). Supporting documentation should include laboratory confirmation of Bartonella infection or a definitive clinical diagnosis made by a physician.

• Differentiate from other febrile illnesses with similar presentations; specific Bartonella species may be noted in documentation but are not separately classified under this code.
• Consider additional codes for specific manifestations or complications of Bartonellosis, such as anemia or endocarditis.
• Ensure the documentation clearly states "Bartonellosis" or a specific Bartonella infection for accurate code assignment.
