ICD10 code of Bronchomalacia and ICD9 code

Bronchomalacia is primarily classified under ICD-10 code Q32.4 (Congenital malformation of bronchus) or J98.09 (Other diseases of bronchus, not elsewhere classified), while in the older ICD-9 system, it was typically coded as 748.3. Because Bronchomalacia involves the structural weakness of the bronchial walls leading to airway collapse, diagnostic coding often depends on whether the condition is considered congenital or acquired.

What exactly is Bronchomalacia?

Bronchomalacia is a condition characterized by flaccidity of the bronchial support cartilage, which causes the airway to narrow or collapse during expiration. This structural instability can lead to chronic cough, wheezing, and recurrent respiratory infections. While some mild cases of Bronchomalacia resolve on their own as a child grows, persistent cases may require long-term monitoring by a pulmonologist to manage airway patency and respiratory health.

How is Bronchomalacia diagnosed and coded?

Diagnosis of Bronchomalacia is typically confirmed through dynamic bronchoscopy, which allows clinicians to visualize the airway during the respiratory cycle. When documenting this condition for medical records, physicians must distinguish between primary Bronchomalacia (often congenital) and secondary forms caused by external compression or chronic inflammation. Common diagnostic markers and findings include:

• Evidence of airway collapse greater than 50% during expiration.


• Persistent expiratory wheezing despite standard asthma therapy.


• Recurrent pneumonia or localized atelectasis.


• Findings on dynamic CT scans or bronchoscopy indicating malformed cartilage rings.

Is Bronchomalacia hereditary or acquired?

Bronchomalacia can be congenital, often associated with genetic syndromes or developmental issues, or it can be acquired through trauma, prolonged mechanical ventilation, or chronic infections. Because Bronchomalacia affects each individual differently, the clinical team at DiseaseMaps.org encourages members to share their diagnostic journeys to better understand the prevalence and management strategies for this rare condition.

Next steps

• Consult a pediatric or adult pulmonologist specializing in airway malacia.


• Request a dynamic bronchoscopy if symptoms remain refractory to standard inhaler treatments.


• Connect with the 3 members living with Bronchomalacia on DiseaseMaps.org to discuss management experiences.


• Keep a detailed log of respiratory triggers to assist your specialist in clinical decision-making.
