Hypersensitivity pneumonitis due to organic dust (J67) ICD-10-CM
The J67 code range covers hypersensitivity pneumonitis due to organic dust with 11 ICD-10-CM diagnosis codes. 10 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- allergic alveolitis and pneumonitis due to inhaled organic dust and particles of fungal, actinomycetic or other origin
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- pneumonitis due to inhalation of chemicals, gases, fumes or vapors J68.0

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the J67 range.
Bagassosis
A diffuse parenchymal lung disease caused by inhaled dust from processing SUGARCANE (bagasse), usually in the manufacturing of wallboard.
Bird Fancier's Lung
A form of alveolitis or pneumonitis due to an acquired hypersensitivity to inhaled avian antigens, usually proteins in the dust of bird feathers and droppings.
Farmer's Lung
A form of alveolitis or pneumonitis due to an acquired hypersensitivity to inhaled antigens associated with farm environment. Antigens in the farm dust are commonly from bacteria actinomycetes (SACCHAROPOLYSPORA and THERMOACTINOMYCES), fungi, and animal proteins in the soil, straw, crops, pelts, serum, and excreta.
Maltworker's Lung
A hypersensitivity pneumonitis associated with the inhalation of organic dust from moldy barley infected with Aspergillus clavatus that is released during harvesting.
Maple-Bark-Stripper's Lung
A hypersensitivity pneumonitis associated with the inhalation of fungal spores of Cryptostroma corticale in workers stripping the bark from maple and sycamore logs affected by sooty bark disease.
Mushroom-Worker's Lung
A hypersensitivity pneumonitis associated with the inhalation of fungal spores that are released during mushroom cultivation.
Suberosis
A hypersensitivity pneumonitis associated with the inhalation of cork dust. The etiologic agents are fungi, including Penicillium glabrum and Aspergillus fumigatus, that colonize the cork and are released during cork processing.
About the J67 Code Range
Hypersensitivity pneumonitis is lung inflammation linked to sensitivity to organic dust. This category sits among lung diseases due to external agents.
The subdivisions distinguish named forms, including J67.0 farmer's lung, J67.2 bird fancier's lung, and J67.7 air conditioner and humidifier lung. J67.8 covers other organic dusts; J67.9 covers unspecified organic dust.
