ICD-10 Code J47 – Bronchiectasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J47 – Bronchiectasis
What it is
Bronchiectasis is a chronic condition in which the bronchial tubes become abnormally widened and damaged. This makes it harder to clear mucus and can lead to repeated lung infections.
Clinical signs
Common findings include chronic cough, daily sputum production, recurrent respiratory infections, and shortness of breath. Clinical features vary; refer to documentation.
When to use this code
Use J47 when the provider documents bronchiectasis as the confirmed diagnosis. It applies whether the condition is localized or diffuse, if the record supports bronchiectasis and not just a nonspecific chronic cough.
Choose this code when imaging, bronchoscopy, or specialist assessment identifies bronchial dilation consistent with bronchiectasis. Check documentation if the note only mentions suspected disease or a history of recurrent infections without confirmation.
Do not use for
Do not use J47 for acute bronchitis, simple chronic bronchitis, or asthma without documented bronchiectasis. Check documentation if the chart uses vague pulmonary symptoms only.
Coding tip
Assign J47 only when bronchiectasis is clearly documented; if the cause or associated condition is stated, code it separately when supported.
