2025 ICD-10-CM code A23.1

Brucellosis due to Brucella abortus.

Use additional code to identify resistance to antimicrobial drugs (Z16.-). Do not use this code for carrier or suspected carrier status (Z22.-), infections complicating pregnancy, childbirth, and the puerperium (O98.-), or infections specific to the perinatal period (P35-P39). Do not use with influenza or other acute respiratory infections (J00-J22) as the primary diagnosis if Brucellosis is present.

Medical necessity for treatment of Brucellosis is established by the confirmation of infection with Brucella abortus, typically through laboratory testing. The severity of symptoms and potential complications may also influence medical necessity determinations.

Physicians diagnose Brucellosis based on symptoms (fever, headache, muscle pain, fatigue), patient history, physical exam, and lab tests (blood, urine, spinal fluid). Treatment typically involves antibiotics. Patient education on preventing infection through avoiding unpasteurized dairy and using protective gear when handling animals is crucial.

In simple words: Brucellosis is an infection caused by Brucella abortus bacteria. People get it from eating or drinking unpasteurized dairy products or breathing in the bacteria around infected animals.

Brucellosis caused by the bacteria Brucella abortus. This is a zoonotic disease, meaning it's transmitted from animals to humans, commonly through consumption of unpasteurized dairy products or inhalation of the bacteria.

Example 1: A farmer develops fever, chills, and body aches after handling a newborn calf from his herd. Lab tests confirm Brucella abortus infection., A traveler experiences persistent fatigue and joint pain after consuming unpasteurized cheese abroad. Blood cultures reveal Brucellosis due to Brucella abortus., A laboratory worker accidentally inhales Brucella abortus while processing samples. They subsequently develop flu-like symptoms and are diagnosed with Brucellosis.

Documentation should include signs and symptoms, patient history (e.g., exposure to animals or consumption of unpasteurized dairy), physical exam findings, and laboratory results confirming Brucella abortus infection.
