J66: ICD10 Code for Airway disease due to specific organic dust

J66 refers to Airway disease due to specific organic dust, which includes occupational and environmental lung diseases caused by the inhalation of dust, chemicals, gases, and other harmful substances. These respiratory conditions are often chronic and can lead to significant pulmonary impairment.

Symptoms

• Chronic cough – Common in pneumoconiosis (J60–J65) and exposure-related diseases (J68–J70)
• Shortness of breath – Progresses with long-term exposure to dust or fumes
• Wheezing and chest tightness – Seen in organic dust-related airway disease (J66, J67)
• Fatigue and reduced exercise tolerance – Related to chronic lung inflammation or fibrosis
• Fever and chills – May accompany hypersensitivity pneumonitis (J67)
• Cough with sputum – Inhalation of irritants or aspiration (J68, J69)

Diagnosis

Diagnosis of Airway disease due to specific organic dust includes occupational history, chest X-ray or CT scan, pulmonary function tests (PFTs), and bronchoalveolar lavage or biopsy in select cases. Identifying the source of exposure is crucial for both treatment and prevention of further lung damage.

ICD10 Code Usage

ICD10 code J66 is used by pulmonologists, occupational medicine specialists, radiologists, and primary care physicians. It aids in workers' compensation claims, long-term respiratory care, medical surveillance programs, and documentation of lung injury due to external agents.

• J60 – Coalworker's pneumoconiosis
• J61 – Pneumoconiosis due to asbestos and other mineral fibers
• J62 – Pneumoconiosis due to dust containing silica
• J63 – Pneumoconiosis due to other inorganic dusts
• J64 – Unspecified pneumoconiosis
• J65 – Pneumoconiosis associated with tuberculosis
• J67 – Hypersensitivity pneumonitis due to organic dust
• J68 – Respiratory conditions due to inhalation of chemicals, gases, fumes and vapors
• J69 – Pneumonitis due to solids and liquids
• J70 – Respiratory conditions due to other external agents

FAQs

Q1: What is ICD10 code J66?
A: It refers to Airway disease due to specific organic dust, caused by inhalation of dusts, chemicals, or organic materials that damage the lungs over time.

Q2: Are these conditions reversible?
A: Most are not fully reversible, but early detection and avoiding further exposure can slow progression and improve symptoms.

Q3: What’s the difference between J60–J65 and J66–J70?
A: J60–J65 refers to inorganic dust-related diseases like coal and asbestos exposure, while J66–J70 involves organic dusts, chemicals, vapors, and aspiration injuries.

Q4: Can these diseases be prevented?
A: Yes—through use of protective equipment, air quality controls, workplace regulations, and regular screening in at-risk populations.

Q5: Who manages these patients?
A: Pulmonologists, occupational health providers, toxicologists, and primary care teams coordinate treatment and exposure management.

Conclusion

ICD10 code J66 supports accurate classification and treatment of Airway disease due to specific organic dust, guiding clinical care and regulatory documentation for respiratory diseases related to occupational and environmental exposures.
