Acute bronchitis due to Hemophilus influenzae

This code identifies an acute inflammation of the bronchial tree specifically caused by Hemophilus influenzae. It signifies a bacterial infection leading to symptoms such as cough, sputum production, and sometimes fever, distinct from chronic bronchitis or other infectious etiologies.

Apply this code when documentation clearly states a diagnosis of acute bronchitis and laboratory confirmation or strong clinical suspicion points to Hemophilus influenzae as the causative organism. This is typically supported by culture results, PCR, or physician's definitive clinical judgment.

• Ensure the documentation specifies "acute" bronchitis; do not use for chronic forms.
• Confirm the bacterial etiology is explicitly stated as Hemophilus influenzae; avoid using for unspecified bacterial bronchitis.
• Sequence this code as the primary diagnosis when it is the reason for the encounter.
