Unspecified pneumoconiosis (J64) ICD-10-CM
The J64 code range covers unspecified pneumoconiosis with 1 ICD-10-CM diagnosis codes. 1 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the J64 range.
Anthracosis
A diffuse parenchymal lung disease caused by accumulation of inhaled CARBON or coal dust. The disease can progress from asymptomatic anthracosis to massive lung fibrosis. This lung lesion usually occurs in coal MINERS, but can be seen in urban dwellers and tobacco smokers.
Pneumoconiosis
A diffuse parenchymal lung disease caused by inhalation of dust and by tissue reaction to their presence. These inorganic, organic, particulate, or vaporized matters usually are inhaled by workers in their occupational environment, leading to the various forms (ASBESTOSIS; BYSSINOSIS; and others). Similar air pollution can also have deleterious effects on the general population.
About the J64 Code Range
The ICD-10 code J64 is used for cases of pneumoconiosis where the specific type or cause is not identified. This code covers lung diseases caused by the inhalation of harmful dusts but without further specification.
Unspecified pneumoconiosis includes conditions commonly known as benign pneumoconiosis, simple pneumoconiosis, complicated pneumoconiosis, mixed dust pneumoconiosis, or just pneumoconiosis. These terms relate to lung damage due to inhaling dust particles like those found in mining or industrial settings. When healthcare providers record chest diseases that stem from dust exposure but cannot pinpoint the exact type, they use J64. This ICD-10 code helps ensure accurate classification and tracking of lung conditions caused by external agents, even when detailed diagnostic information is unavailable. Understanding that J64 serves as the code for unspecified pneumoconiosis assists medical coders and clinicians in selecting the proper billing and documentation code when facing ambiguous dust-related lung diseases.
