What This Code Means

A serious blood infection in a newborn caused by anaerobic bacteria (bacteria that grow without oxygen).

Coding Tips

•Anaerobic sepsis in newborns is less common; ensure anaerobic culture results are documented and reviewed
•Identify the specific anaerobic organism if possible for more precise coding

Clinical Significance

Anaerobic sepsis in newborns is a serious infection caused by bacteria that grow without oxygen, often associated with maternal chorioamnionitis, prolonged rupture of membranes, or gastrointestinal sources. These infections can be particularly challenging to diagnose and treat due to special culture requirements and potential for mixed bacterial infections.

Documentation Requirements

✓Positive anaerobic culture results
✓Clinical signs of sepsis syndrome
✓Associated maternal risk factors
✓Anaerobic culture techniques utilized
✓Antibiotic coverage for anaerobic organisms
✓Gestational age and birth weight
✓Source of infection if identified
✓Treatment response and duration

Commonly Confused Codes
