ICD-10 Code J15.69 – Pneumonia due to other Gram-negative bacteria (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J15.69 – Pneumonia due to other Gram-negative bacteria
What it is
This code identifies pneumonia caused by Gram-negative bacteria other than the specific organisms named in more detailed ICD-10 categories. Use it when the record documents a Gram-negative bacterial pneumonia but does not name a more specific codeable organism.
Clinical signs
Clinical features vary; refer to documentation. Typical pneumonia findings may include cough, fever, shortness of breath, chest pain, and imaging consistent with lung infection, but the organism must be documented as a Gram-negative bacterium.
When to use this code
Use J15.69 when the provider documents pneumonia due to a Gram-negative organism that is not separately listed elsewhere in ICD-10-CM. It also fits when the note names a qualifying Gram-negative bacterium but does not support a more specific code. If the organism is not stated, check documentation before assigning this code.
Do not use for
Do not use this code for viral, fungal, aspiration, or interstitial pneumonias. It is also wrong when a more specific organism code is documented or can be confirmed.
Coding tip
Verify the exact organism in the provider note and code the most specific pneumonia category available.
