Specific code icon 2014 ICD-10-CM Diagnosis Code J43.9

Emphysema, unspecified

  • J43.9 is a billable ICD-10-CM code that can be used to specify a diagnosis.
  • On October 1, 2014 ICD-10-CM will replace ICD-9-CM in the United States, therefore, J43.9 and all other ICD-10-CM codes should only be used for training or planning purposes until then.
Clinical Information
  • A condition of the lung characterized by increase beyond normal in the size of air spaces distal to the terminal bronchioles, either from dilatation of the alveoli or from destruction of their walls.
  • A subcategory of chronic obstructive pulmonary disease (copd). It occurs in people who smoke and suffer from chronic bronchitis. It is characterized by inflation of the alveoli, alveolar wall damage, and reduction in the number of alveoli, resulting in difficulty breathing. Alveoli are the vital lung structures where the transfer of oxygen and carbon dioxide takes place.
  • An abnormal increase in the size of the air spaces, resulting in breathing difficulty and an increased sensitivity to infection
  • Emphysema is a type of chronic obstructive pulmonary disease (copd) involving damage to the air sacs (alveoli) in the lungs. As a result, your body does not get the oxygen it needs. Emphysema makes it hard to catch your breath. You may also have a chronic cough and have trouble breathing during exercise.the most common cause is cigarette smoking. If you smoke, quitting can help prevent you from getting the disease. If you already have emphysema, not smoking might keep it from getting worse. Treatment is based on whether your symptoms are mild, moderate or severe. Treatments include inhalers, oxygen, medications and sometimes surgery to relieve symptoms and prevent complications.
  • Enlargement of air spaces distal to the terminal bronchioles where gas-exchange normally takes place. This is usually due to destruction of the alveolar wall. Pulmonary emphysema can be classified by the location and distribution of the lesions.
  • Pulmonary emphysema is a disorder affecting the alveoli (tiny air sacs) of the lungs. The transfer of oxygen and carbon dioxide in the lungs takes place in the walls of the alveoli. In emphysema, the alveoli become abnormally inflated, damaging their walls and making it harder to breathe. People who smoke or have chronic bronchitis have an increased risk of emphysema.
  • Subcategory of chronic obstructive pulmonary disease; characterized by anatomic alterations of the lungs, such as the enlargement of airspaces and destruction of alveolar walls.

Mortality Data
