Brucella melitensis

This code represents an infection caused by Brucella melitensis, a specific species of bacteria responsible for brucellosis. This zoonotic disease can manifest with a variety of symptoms, including fever, sweats, malaise, anorexia, headache, and muscle pain, and can affect multiple organ systems.

Apply this code when documentation confirms a diagnosis of brucellosis specifically attributed to Brucella melitensis. This typically requires laboratory confirmation, such as positive blood cultures or serological tests identifying antibodies to B. melitensis. Clinical symptoms consistent with brucellosis in a patient with relevant exposure history (e.g., contact with infected animals or consumption of unpasteurized dairy products) would also support its use.

• Ensure the documentation specifies Brucella melitensis as the causative agent; otherwise, a more general brucellosis code may be appropriate.
• Code any associated manifestations or complications of brucellosis (e.g., osteomyelitis, endocarditis) in addition to this primary diagnosis.
• Review for potential exposure history or risk factors documented, as this can support the diagnosis.
