J15.20

HCC Category Mapping

What This Code Means

Pneumonia caused by Staphylococcus bacteria, but the specific type or antibiotic resistance pattern has not been identified.

Coding Tips

• •Use this code only when staphylococcal pneumonia is confirmed but susceptibility testing is unavailable or pending
• •Update coding if susceptibility results become available to use more specific codes J15.211 or J15.212

Clinical Significance

Pneumonia due to unspecified Staphylococcus is a significant bacterial respiratory infection that increases morbidity, particularly in elderly and immunocompromised patients. Staphylococcal pneumonia requires organism identification and susceptibility testing to guide appropriate antibiotic therapy. Accurate organism identification impacts treatment decisions, infection control measures, and risk stratification.

Documentation Requirements

• ✓Documentation of pneumonia diagnosis with causative organism identified as unspecified Staphylococcus
• ✓Chest imaging (X-ray or CT) findings consistent with pneumonia
• ✓Clinical signs and symptoms documented (fever, cough, dyspnea, sputum production)
• ✓Staphylococcal organism identified but susceptibility results pending or unavailable
• ✓Antibiotic therapy prescribed and documented
• ✓Severity assessment (need for oxygen, hospitalization, intensive care)
