Family history of other diseases of the respiratory system

This code indicates a patient has a family history of respiratory conditions that are not specifically asthma or other chronic lower respiratory diseases. This history suggests a potential genetic predisposition or shared environmental factors contributing to respiratory health issues within the family unit.

Use this code when a patient reports a family history of conditions like cystic fibrosis, sarcoidosis, pulmonary fibrosis, or other non-asthmatic/non-COPD related respiratory diseases in a first-degree relative (parent, sibling, child) or other close family member. This information is often gathered during a comprehensive history and physical examination.

• Ensure the documented family history specifies a respiratory condition other than asthma or chronic lower respiratory diseases.
• Do not use this code if the family history is specifically for asthma or other chronic lower respiratory diseases; refer to the Excludes2 note.
• This code is typically used as a secondary diagnosis to provide additional context for the patient's overall health risk assessment.
