481
ICD-9-CMThis code identifies pneumonia specifically caused by the bacterium Streptococcus pneumoniae. It represents an acute inflammatory condition of the lung parenchyma, typically characterized by consolidation and respiratory symptoms.
Use this code when documentation explicitly states "pneumococcal pneumonia" or "pneumonia due to Streptococcus pneumoniae." Confirmation via sputum culture or other microbiological testing, though ideal, is not always required if the physician's clinical diagnosis is clear.
