Acute bronchitis due to other specified organisms

This code signifies an acute inflammation of the bronchial tree caused by a pathogen other than those specifically classified elsewhere (e.g., Mycoplasma, Chlamydia, Streptococcus, Haemophilus influenzae, viral). Patients typically present with cough, sputum production, and sometimes fever, with symptoms resolving within a few weeks. It indicates a bacterial or fungal etiology that is identified but not covered by more specific acute bronchitis codes.

Apply this code when documentation explicitly states acute bronchitis due to a specified organism, and that organism is not one for which a more specific ICD-10-CM code exists (e.g., acute bronchitis due to Pseudomonas aeruginosa or Klebsiella pneumoniae). The physician's notes must clearly identify the causative agent through culture results or clinical judgment.

• Requires documentation of the specific organism causing the acute bronchitis.
• Do not use if the organism is unspecified; use J20.9 (Acute bronchitis, unspecified) instead.
• Distinguish from chronic bronchitis exacerbations, which are coded differently (J41-J42 series).
