ICD-10 Code J20.8 – Acute bronchitis due to other specified organisms (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J20.8 – Acute bronchitis due to other specified organisms
What it is
J20.8 identifies acute bronchitis caused by an organism not named in another more specific code. It covers a short-term inflammation of the bronchi when documentation supports an “other specified” infectious cause.
Clinical signs
Typical findings include acute cough, chest discomfort, and sputum production, with or without wheezing. Clinical features vary; refer to documentation for the identified organism and any confirmed lower respiratory involvement.
When to use this code
Use this code when the record states acute bronchitis and names a causative organism that is not separately indexed to a more specific ICD-10 code. It also fits when the provider documents “other specified organisms” or an equivalent phrase. Check documentation if the causal organism is unclear or not confirmed.
Do not use for
Do not use J20.8 for bronchitis caused by organisms with their own specific code, or when the diagnosis is chronic bronchitis, bronchiectasis, or pneumonia. If the chart only says cough or upper respiratory infection, check documentation.
Coding tip
Match the organism named in the note to the Alphabetic Index before assigning J20.8.
