What This Code Means

A serious lung infection caused by Acinetobacter baumannii, a gram-negative bacterium often resistant to multiple antibiotics.

Coding Tips

• •Document whether this is a healthcare-associated infection, as Acinetobacter baumannii is commonly nosocomial
• •Verify antibiotic susceptibility results are documented, as resistance patterns affect treatment decisions

Clinical Significance

Acinetobacter baumannii pneumonia is a highly resistant gram-negative infection predominantly occurring in healthcare settings, particularly intensive care units. It is a major concern due to multi-drug resistance patterns and high mortality rates, and its presence typically indicates a critically ill patient with significant resource utilization.

Documentation Requirements

• ✓Culture identification confirming Acinetobacter baumannii as the causative pathogen
• ✓Clinical and radiographic evidence of pneumonia
• ✓Antibiotic sensitivity results and documentation of targeted antimicrobial therapy
• ✓Documentation of healthcare-associated acquisition if applicable (ventilator-associated pneumonia)
• ✓Severity indicators including ventilator status, ICU admission, sepsis screening
• ✓Any multi-drug resistance patterns documented
