P23.4

What This Code Means

A lung infection in a newborn caused by E. coli bacteria, typically acquired from maternal flora during delivery. This gram-negative organism can cause serious neonatal infections.

Coding Tips

• •Specify if the strain is K1 capsule positive when documented, as this is associated with more severe disease
• •Consider whether this is early-onset (within 72 hours) or late-onset neonatal sepsis, as this affects coding and clinical management
