Pneumonia due to Hemophilus influenzae

This code signifies an acute inflammatory condition of the lung parenchyma caused specifically by infection with Hemophilus influenzae. It involves consolidation of lung tissue and can present with symptoms such as cough, fever, dyspnea, and pleuritic chest pain. This diagnosis indicates a bacterial etiology for the pneumonia.

Use this code when documentation explicitly states pneumonia caused by Hemophilus influenzae. This diagnosis is typically supported by positive sputum cultures, blood cultures, or other laboratory tests identifying H. influenzae as the causative agent in a patient presenting with clinical signs and symptoms of pneumonia.

• Ensure the documentation specifies Hemophilus influenzae as the causative organism; "bacterial pneumonia" alone is insufficient.
• Distinguish from other bacterial pneumonias; the specific organism must be identified.
• Remember the Excludes1 note: do not code this with congenital pneumonia due to H. influenzae (P23.6).
