ICD-10 Code J20.5 – Acute bronchitis due to respiratory syncytial virus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J20.5 – Acute bronchitis due to respiratory syncytial virus
What it is
J20.5 identifies acute bronchitis caused by respiratory syncytial virus (RSV). Use it when the record documents an acute lower respiratory infection with bronchial inflammation linked to RSV.
Clinical signs
Typical findings include cough, wheezing, and chest congestion, with symptoms of acute bronchitis. Clinical features vary; refer to documentation for RSV confirmation and the provider’s diagnosis.
When to use this code
Use J20.5 when the clinician specifically documents acute bronchitis due to RSV. It also fits cases where RSV is identified and the bronchitis diagnosis is clearly linked to that virus. Check documentation if the note only says RSV infection or bronchiolitis.
Do not use for
Do not use this code for uncomplicated RSV infection without bronchitis, or for bronchiolitis unless the provider documents bronchitis. Do not assume the cause if RSV is not stated.
Coding tip
Assign J20.5 only when both acute bronchitis and RSV cause are documented together.
