Maple bark-strippers' lung

This code represents a specific form of hypersensitivity pneumonitis, an inflammatory lung disease caused by an allergic reaction to inhaled organic dusts. Specifically, it refers to the interstitial lung disease resulting from exposure to the mold Cryptostroma corticale, which is found on maple bark. The condition manifests as flu-like symptoms, cough, and dyspnea, often progressing to chronic lung damage with continued exposure.

Use this code for patients diagnosed with hypersensitivity pneumonitis directly attributed to exposure to maple bark dust. Documentation should clearly indicate a history of exposure to maple bark (e.g., in occupations involving maple tree processing or handling) and clinical findings consistent with hypersensitivity pneumonitis, such as restrictive lung disease on pulmonary function tests or characteristic imaging findings.

• Ensure documentation explicitly links the lung condition to maple bark exposure, not just general organic dust.
• Consider co-reporting with codes for associated respiratory symptoms or complications, such as chronic bronchitis or pulmonary fibrosis, if present.
• Differentiate from other forms of hypersensitivity pneumonitis by confirming the specific allergen.
