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.

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
- Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
- No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
- Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
