Congenital pneumonia (P23)

The ICD-10 code P23 classifies various types of congenital pneumonia, which are lung infections present at birth. This coding section includes specific subcodes that identify the infectious agent responsible, such as viral or bacterial causes.

These codes are used to accurately document and differentiate congenital pneumonia cases based on their cause. For example, P23.0 covers congenital pneumonia due to viral agents, often referenced as congenital viral pneumonia. Bacterial causes have distinct codes: P23.1 for Chlamydia pneumoniae infections (also called neonatal chlamydial pneumonia), P23.2 for staphylococcal pneumonia, P23.3 for group B streptococcal pneumonia, P23.4 for Escherichia coli pneumonia, and P23.5 for pneumonia caused by Pseudomonas bacteria. Additional bacterial infections fall under P23.6, while P23.8 includes other organisms. If the cause is unclear, P23.9 is used for unspecified congenital pneumonia, sometimes identified simply as neonatal pneumonia. These distinctions help medical professionals ensure proper diagnosis, treatment, and coding accuracy for this serious perinatal condition.

Instructional Notations

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

  • infective pneumonia acquired in utero or during birth

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • neonatal pneumonia resulting from aspiration P24
