ICD-10 Code A23.8 – Other brucellosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A23.8 – Other brucellosis
What it is
A23.8 identifies brucellosis when the organism or presentation does not fit a more specific brucellosis code. Use it for confirmed brucella infection that is documented as other or unspecified by type.
Clinical signs
Clinical features vary; refer to documentation. Brucellosis commonly presents with fever, sweats, malaise, and musculoskeletal pain, but the chart should support the diagnosis and any stated species or site involvement.
When to use this code
Assign A23.8 when the provider documents “other brucellosis” or confirms brucellosis without a more specific category available. Use it for cases that are not classified as the listed brucellosis subtypes. If the record is unclear, check documentation before coding.
Do not use for
Do not use this code for suspected brucellosis, ruled-out infection, or a more specific brucellosis type already documented. If the organism or clinical form is identified elsewhere in the record, code the more precise option.
Coding tip
Verify the provider’s wording carefully; “other brucellosis” should be supported by the diagnosis statement, not inferred from exposure history alone.
