Airway disease due to specific organic dust (J66)
The ICD-10 code J66 group identifies specific airway diseases caused by organic dust exposure. These codes are used to classify respiratory conditions resulting from inhaling various organic dusts in occupational or environmental settings.
This section includes codes for diseases like J66.0 (Byssinosis), also known as "pneumoconiosis caused by organic dust" or "endotoxicosis," typically related to cotton dust exposure. J66.1 covers Flax-dressers' disease, caused by flax dust and sometimes referred to by similar terms including byssinosis. J66.2 (Cannabinosis) denotes lung disease from cannabis dust. Other organic dust-related airway diseases fall under J66.8, which encompasses conditions such as pulmonary mycotoxicosis or illness from sisal dust. These codes help healthcare providers and coders accurately document lung diseases specifically linked to organic dust exposure, facilitating precise diagnosis and appropriate treatment planning.
Instructional Notations
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- allergic alveolitis J67
- asbestosis J61
- bagassosis J67.1
- farmer's lung J67.0
- hypersensitivity pneumonitis due to organic dust J67
- reactive airways dysfunction syndrome J68.3
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Bronchoconstriction
Narrowing of the caliber of the BRONCHI, physiologically or as a result of pharmacological intervention.
Byssinosis
A condition of BRONCHOCONSTRICTION resulting from hypersensitive reaction to inhaled dust during the initial processing of cotton, flax, or hemp in the textile industry. Symptoms include wheezing and tightness in the chest.
