Family history of asthma and oth chronic lower resp diseases

This diagnosis code indicates a patient has a family history of asthma or other chronic lower respiratory conditions, such as chronic bronchitis or emphysema. It signifies a genetic predisposition or increased risk for these conditions due to their occurrence in immediate or extended family members.

This code is appropriate when documenting a patient's family medical history that includes asthma, COPD, or other chronic lower airway diseases, even if the patient themselves does not currently have the condition. It is used to highlight a risk factor that may influence screening, prevention strategies, or diagnostic considerations.

• Assign this code as a secondary diagnosis to indicate a risk factor, not a current condition.
• Distinguish carefully between family history of chronic lower respiratory diseases and other respiratory system diseases.
• Ensure documentation clearly specifies the type of chronic lower respiratory disease in the family history when possible.
