Other forms of bartonellosis

This code represents various less common or unspecified clinical manifestations of Bartonella infection that do not fit into more specific categories like cat-scratch disease or trench fever. It encompasses a range of systemic or localized infections caused by Bartonella species other than those with dedicated codes, or when the specific Bartonella species or clinical syndrome is not fully identified.

Use this code when documentation indicates a confirmed Bartonella infection, but the specific type (e.g., cat-scratch disease, trench fever, Carrión's disease) is not specified, or the presentation is atypical. This code is appropriate for conditions such as Bartonella endocarditis, bacillary angiomatosis, or peliosis hepatis when the specific Bartonella species is not otherwise classified. Documentation should clearly state "bartonellosis, other forms" or a specific Bartonella infection not covered by more precise codes.

• Do not use this code for typical cat-scratch disease (lymphadenopathy) or trench fever, as more specific codes exist.
• Always strive for the most specific Bartonella code available if the clinical documentation allows.
• Ensure the medical record supports a diagnosis of bartonellosis, typically through laboratory confirmation or strong clinical evidence.
