Sepsis of newborn due to anaerobes

This code signifies a severe systemic inflammatory response syndrome (SIRS) in a newborn caused by an anaerobic bacterial infection. It indicates a life-threatening condition where the infant's body is overwhelmed by the infection, leading to organ dysfunction.

Apply this code when documentation explicitly states sepsis in a neonate and identifies an anaerobic organism as the causative agent. Supporting documentation includes positive blood cultures or other sterile site cultures growing anaerobic bacteria, along with clinical signs of neonatal sepsis.

• Always confirm the specific bacterial type (anaerobic) is documented; do not assume based on clinical picture alone.
• Do not use if the sepsis is due to other bacterial types (e.g., gram-positive, gram-negative) or is unspecified.
• Sequence this code as the principal diagnosis when it is the primary reason for admission, followed by codes for any associated organ dysfunction.
