Congenital pneumonia due to other organisms

This code signifies pneumonia present at birth, caused by an infectious agent other than those specifically classified elsewhere (e.g., viral, bacterial, chlamydial, or protozoal). It indicates an inflammatory condition of the lungs acquired in utero or during the birth process, resulting from an unspecified or less common organism.

Use this code when documentation confirms congenital pneumonia and the causative organism is identified as something other than a virus, bacteria, Chlamydia, or protozoa, or if the specific organism is unknown but clearly not one of the more common types. Supporting documentation should include a diagnosis of congenital pneumonia and a statement indicating "other organisms" or an unspecified non-bacterial/non-viral/non-chlamydial/non-protozoal etiology.

• Ensure the documentation explicitly states "congenital pneumonia" and specifies "other organisms" or an organism not covered by more specific P23 codes.
• Avoid using this code if a specific bacterial, viral, chlamydial, or protozoal cause is identified; instead, use the appropriate P23 subcategory.
• Do not use this code for pneumonia acquired postnatally; refer to codes in Chapter 10 (Diseases of the Respiratory System) for those cases.
