ICD-10 Code J15.0 – Pneumonia due to Klebsiella pneumoniae (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J15.0 – Pneumonia due to Klebsiella pneumoniae
What it is
This code identifies pneumonia caused by Klebsiella pneumoniae, a specific bacterial lung infection. Use it when the documentation names this organism as the cause.
Clinical signs
Typical findings include cough, fever, shortness of breath, and evidence of pneumonia on imaging. Clinical features vary; refer to documentation.
When to use this code
Use J15.0 when the provider documents pneumonia due to Klebsiella pneumoniae, or when the organism is clearly identified as the cause. Code it from the final diagnosis, discharge summary, or microbiology-linked documentation. If the record only says pneumonia without an organism, do not assume this code.
Do not use for
Do not use this code for Klebsiella infection at another site, such as urinary or bloodstream infection, unless pneumonia is also documented. Check documentation if the organism is not specifically linked to the pneumonia.
Coding tip
Assign J15.0 only when Klebsiella pneumoniae is explicitly tied to the pneumonia in the record.
