A type 1 Excludes note is a pure excludes note. It means “NOT CODED HERE!” An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Information for Patients
Interstitial Lung Diseases
Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. The inflammation and scarring make it hard to get enough oxygen. The scarring is called pulmonary fibrosis.
Breathing in dust or other particles in the air is responsible for some types of interstitial lung diseases. Specific types include
- Black lung disease among coal miners, from inhaling coal dust
- Farmer's lung, from inhaling farm dust
- Asbestosis, from inhaling asbestos fibers
- Siderosis, from inhaling iron from mines or welding fumes
- Silicosis, from inhaling silica dust
Other causes include autoimmune diseases or occupational exposures to molds, gases, or fumes. Some types of interstitial lung disease have no known cause.
Treatment depends on the type of exposure and the stage of the disease. It may involve medicines, oxygen therapy, or a lung transplant in severe cases.
- Hypersensitivity pneumonitis
- Interstitial lung disease
- Interstitial lung disease - adults - discharge
- Pulmonary function tests
Also called: IPF, Idiopathic pulmonary fibrosis
Pulmonary fibrosis is a condition in which the tissue deep in your lungs becomes scarred over time. This tissue gets thick and stiff. That makes it hard for you to catch your breath, and your blood may not get enough oxygen.
Causes of pulmonary fibrosis include environmental pollutants, some medicines, some connective tissue diseases, and interstitial lung disease. Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. In most cases, the cause cannot be found. This is called idiopathic pulmonary fibrosis.
- Shortness of breath
- A dry, hacking cough that doesn't get better
- Weight loss for no known reason
- Aching muscles and joints
- Clubbing, which is the widening and rounding of the tips of the fingers or toes
Your doctor may use your medical history, imaging tests, a biopsy, and lung function tests to diagnose pulmonary fibrosis. There is no cure. Treatments can help with symptoms and improve your quality of life. They include medicines, oxygen therapy, pulmonary rehabilitation, or a lung transplant.
