Byssinosis

This code represents a specific form of occupational lung disease caused by the inhalation of cotton dust or other vegetable fibers. It is characterized by acute airway constriction, often presenting as chest tightness and dyspnea, particularly on the first day of the work week. Prolonged exposure can lead to chronic respiratory impairment.

Use this code when documentation clearly indicates a diagnosis of byssinosis, typically in individuals with a history of occupational exposure to cotton, flax, or hemp dust. Supporting documentation should include a detailed occupational history, clinical symptoms consistent with the condition, and potentially pulmonary function test results.

• Ensure the medical record explicitly links the respiratory symptoms to occupational exposure to cotton or other specified vegetable fibers.
• Do not confuse this with other forms of pneumoconiosis; byssinosis is distinct due to its specific causative agent and acute presentation.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, especially for occupational health evaluations.
