Default principal diagnosis: inpatient Yes · outpatient Yes

Clinical InformationClinical

  • Bronchomalacia

    a congenital or acquired condition of underdeveloped or degeneration of cartilage in the bronchi. this results in a floppy bronchial wall making patency difficult to maintain. it is characterized by wheezing and difficult breathing.

  • Bronchomalacia

    a congenital or acquired abnormality of the wall of the bronchi. in congenital cases, there is lack of rigidity in the cartilage of the bronchial wall. in acquired cases, the cartilage of the bronchial wall is degenerated, secondary to tracheostomy or presence of a breathing tube. symptoms include noisy breathing and wheezing.

  • Tracheobronchomalacia

    a rare congenital or acquired disorder characterized by excessive collapsibility of the trachea and major bronchi resulting in breathing problems. it is caused by damage to the tracheobronchial cartilage.

Patient EducationClinical

Bronchial Disorders

When you breathe in, the air travels down through your trachea (windpipe). It then goes through two tubes to your lungs. These tubes are your bronchi. Bronchial disorders can make it hard for you to breathe.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
