Bartonellosis (Oroya fever)

During the active phase of the disease, medical records confirming an active Bartonellosis infection — such as laboratory results, physician diagnoses, or hospitalization records — support the 100% rating. Once the disease resolves, evidence of residual conditions becomes central. For endocarditis, cardiology records, echocardiograms, and documentation of heart function help establish severity. For skin lesions, dermatology records and descriptions of size, number, and location are relevant. Statements from you or your treating providers describing how residual symptoms affect your daily activities and ability to work can help establish severity under the body system being rated. The specific evidence needed will depend on which residual condition is being evaluated and what that condition's rating criteria require.
