Cutaneous and mucocutaneous bartonellosis

This code represents an infection caused by Bartonella bacteria that primarily affects the skin and/or mucous membranes. It manifests as various skin lesions, such as papules, nodules, or ulcers, and can involve the conjunctiva or oral mucosa. This condition is often associated with exposure to infected animals or vectors.

Use this code when documentation specifies a diagnosis of cutaneous or mucocutaneous bartonellosis, such as verruga peruana or bacillary angiomatosis affecting the skin. Supporting documentation should clearly indicate the Bartonella infection is localized to the skin or mucous membranes, often confirmed by biopsy or serology.

• Differentiate from systemic bartonellosis, which would require a more specific code for the systemic manifestation.
• Ensure documentation specifies "cutaneous" or "mucocutaneous" to support this localized code.
• Consider co-morbidities like HIV/AIDS, as bacillary angiomatosis is common in immunocompromised individuals, and code those conditions separately.
