Bronchiectasis is a chronic respiratory condition characterized by the irreversible widening of the bronchi, the airways of the lungs. Accurate diagnosis and coding are crucial for effective patient management and healthcare billing. In the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) system, the Bronchiectasis Diagnosis Code is J47.9. This article delves into the specifics of the J47.9 code, providing a comprehensive understanding for healthcare professionals and anyone seeking clarity on this diagnostic classification.
Decoding ICD-10-CM Code J47.9 for Bronchiectasis
ICD-10-CM code J47.9 is designated as “Bronchiectasis, uncomplicated.” This is a billable and specific code, meaning it is precise enough to be used for reimbursement purposes. The code officially came into effect on October 1, 2015, with the U.S. implementation of ICD-10-CM, and the latest 2025 edition remains current as of October 1, 2024. It’s important to note that while J47.9 is the American ICD-10-CM version, international adaptations of ICD-10 may have variations in coding.

The term “uncomplicated” in J47.9 is key. It signifies bronchiectasis without acute lower respiratory infection or acute exacerbation, which are classified under different codes (J47.0 and J47.1 respectively). J47.9 is applicable when “Bronchiectasis NOS” (Not Otherwise Specified) is documented, indicating cases where the specific type or cause of bronchiectasis is not further specified.
Synonyms and Clinical Understanding of J47.9
Several terms are considered approximate synonyms for J47.9, aiding in the identification of relevant patient records and documentation. These include:
- Bronchiectasis
- Post-infective bronchiectasis
- Postinfectious bronchiectasis
Clinically, bronchiectasis under J47.9 refers to a persistent, abnormal dilation of the bronchi. This irreversible widening of the bronchial tree leads to the accumulation of mucus and secretions. This build-up obstructs airflow and creates an environment susceptible to recurrent infections. While various factors can cause bronchiectasis, bacterial infection is frequently identified as a primary underlying cause.
J47.9 Code History and Context within ICD-10-CM
The code J47.9 was introduced in 2016 with the first non-draft version of ICD-10-CM and has remained unchanged through the 2025 update. This stability is reflected in its code history, showing “no change” annotations from 2017 to 2025.
Within the broader ICD-10-CM system, J47.9 falls under the category J47 (Bronchiectasis), which is part of the larger section J00-J99 (Diseases of the Respiratory System). Codes adjacent to J47.9, such as J47.0 (Bronchiectasis with acute lower respiratory infection) and J47.1 (Bronchiectasis with acute exacerbation), provide further specificity in coding bronchiectasis cases based on their clinical presentation. Understanding these related codes is crucial for accurate and nuanced medical coding practices.
Conclusion
Accurate utilization of the bronchiectasis diagnosis code J47.9 is essential for medical coding, billing, and epidemiological tracking of this chronic respiratory condition. By understanding the nuances of “uncomplicated” bronchiectasis as defined by J47.9, healthcare providers and coding professionals can ensure precise documentation and contribute to better patient care and data integrity.
