What This Code Means

Pneumonia caused by Pseudomonas bacteria, typically a gram-negative organism found in healthcare and environmental settings.

Coding Tips

• •This code is complete and does not require further specification
• •Note any antibiotic resistance patterns documented in culture results

Clinical Significance

Pneumonia due to Pseudomonas is a significant bacterial respiratory infection that increases morbidity, particularly in elderly and immunocompromised patients. Pseudomonas pneumonia is frequently healthcare-associated and carries high mortality, particularly in ventilated patients and those with structural lung disease or immunosuppression. Accurate organism identification impacts treatment decisions, infection control measures, and risk stratification.

Documentation Requirements

• ✓Documentation of pneumonia diagnosis with causative organism identified as Pseudomonas
• ✓Chest imaging (X-ray or CT) findings consistent with pneumonia
• ✓Clinical signs and symptoms documented (fever, cough, dyspnea, sputum production)
• ✓Culture, sputum, or molecular testing results confirming the specific organism
• ✓Antibiotic therapy prescribed and documented
• ✓Severity assessment (need for oxygen, hospitalization, intensive care)
• ✓Antibiotic susceptibility panel results, especially for resistant gram-negative patterns
