ICD-10 Code J15.61 – Pneumonia due to Acinetobacter baumannii (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J15.61 – Pneumonia due to Acinetobacter baumannii
What it is
This code identifies pneumonia caused by Acinetobacter baumannii, a specific bacterial infection of the lungs. Use it when the record clearly names this organism as the cause.
Clinical signs
Clinical features vary; refer to documentation. Typical pneumonia findings may include cough, fever, shortness of breath, and chest imaging consistent with lung infection, with Acinetobacter baumannii confirmed as the cause.
When to use this code
Use J15.61 when the provider documents pneumonia due to Acinetobacter baumannii, whether community-acquired or healthcare-associated. It is appropriate when the organism is identified in the chart and linked to the pneumonia diagnosis. If the organism is listed without a pneumonia diagnosis, check documentation.
Do not use for
Do not use this code for colonization, screening, or infection at another site without pneumonia. If the chart only says “Acinetobacter” or the cause is unclear, code only what is documented.
Coding tip
Link the organism to pneumonia in the provider’s wording before assigning J15.61.
