J70: Respiratory conditions due to other external agents

Respiratory conditions due to other external agents, classified under the code range J70 in ICD-10, refer to a group of diseases impacting the respiratory system that are triggered by factors in the external environment. These conditions can be caused by numerous different factors, from inhaling harmful substances like chemicals and dust to exposure to extreme temperatures. Symptoms common to these conditions often involve difficulty breathing, cough, chest pain and wheezing. Depending on the specific type of condition under this classification, disease progression can range from slow and chronic development over time to immediate, acute respiratory distress. The respiratory system, specifically the airways, lungs, and associated nerves and muscles, are primarily affected by these diseases. These conditions do not spread from person to person as they are reactions to environmental factors.
