ICD-10 Code J47.9 – Bronchiectasis, uncomplicated (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J47.9 – Bronchiectasis, uncomplicated
What it is
J47.9 identifies bronchiectasis without a stated complication. It means the bronchi are permanently widened, which can make mucus clearance poor and increase infection risk.
Clinical signs
Common findings include chronic cough, sputum production, recurrent respiratory infections, and wheezing. Clinical features vary; refer to documentation.
When to use this code
Use J47.9 when the provider documents bronchiectasis and does not specify a complication or an associated condition that changes coding. It also fits cases where the record simply states uncomplicated bronchiectasis. If the note includes an underlying cause or a related complication, code that documentation instead.
Do not use for
Do not use J47.9 when bronchiectasis is documented with a specific complication, such as an exacerbation or another coded associated condition. Do not guess at complications; check documentation.
Coding tip
Code J47.9 only when the chart clearly supports bronchiectasis and no complication is documented.
