Bartonellosis (A44)

ICD-10 code A44 covers all forms of Bartonellosis, an infection caused by Bartonella bacteria affecting different body systems. These codes specify the type and severity, from systemic illness to skin-related manifestations.

The ICD-10 code for systemic bartonellosis (A44.0) identifies serious bloodstream infections known as Oroya fever or hemolytic anemia caused by Bartonella bacilliformis. For skin and mucous membrane infections like Verruga peruana, use A44.1, which captures cutaneous and mucocutaneous bartonellosis. A44.8 includes other rare forms such as neurobartonellosis and bacillary peliosis, which can be caused by Bartonella species like B. henselae or B. quintana. When the type of bartonellosis is not specified, A44.9 applies, including asymptomatic cases or unspecified Bartonella infections. Using these exact codes ensures precise reporting and aids in clinical differentiation of bartonellosis manifestations for treatment and epidemiological tracking.
