ICD-10 Code A41.54 – Sepsis due to Acinetobacter baumannii (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A41.54 – Sepsis due to Acinetobacter baumannii
What it is
A41.54 identifies sepsis caused by Acinetobacter baumannii, a serious bloodstream infection tied to this specific organism. Use it when the record clearly links sepsis to A. baumannii.
Clinical signs
Clinical features vary; refer to documentation. Sepsis is typically documented with systemic infection and evidence of organ dysfunction, and the causative organism should be named when known.
When to use this code
Use this code when the provider documents sepsis due to Acinetobacter baumannii, or when the organism is identified and the diagnosis states sepsis from that pathogen. If the record only says infection or bacteremia without sepsis, this code is not appropriate.
Confirm that the organism is specifically A. baumannii and not another Acinetobacter species. If documentation is unclear, query the provider before assigning the code.
Do not use for
Do not use A41.54 for colonization, simple infection, or bacteremia without sepsis. Do not assume this code applies to unspecified Acinetobacter infections; check documentation.
Coding tip
Code the sepsis only when the provider explicitly links it to Acinetobacter baumannii.
