2026 ICD-10-CM Diagnosis Code B96.83 – Acinetobacter baumannii as the cause of diseases classified elsewhere
What it is
This code identifies Acinetobacter baumannii as the infectious organism causing a condition classified elsewhere. Use it when the record links this bacterium to another diagnosed infection or disease.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart describes infection signs such as fever, localized inflammation, or a culture-confirmed Acinetobacter baumannii source.
When to use this code
Use B96.83 when the provider documents Acinetobacter baumannii as the cause of a separate condition, such as pneumonia, wound infection, or urinary infection. You should code the underlying infection first, then add this organism code when documentation supports it.
Do not use for
Do not use this code for suspected infection without confirmation or when the organism is not documented as the cause. Check documentation if the chart names only colonization or carrier status.
Coding tip
Pair this code with the specific infection diagnosis and verify the provider explicitly identifies Acinetobacter baumannii as the causative organism.
