About Z57.3

Z57.3 is the ICD-10-CM diagnosis code for occupational exposure to other air contaminants. It belongs to category Z57 (occupational exposure to risk factors), block Z55-Z65 (persons with potential health hazards related to socioeconomic and psychosocial circumstances) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within Z57, choose Z57.3 (other air contaminants) only when documentation doesn't support a more specific option: noise (Z57.0), radiation (Z57.1), dust (Z57.2), toxic agents in agriculture (Z57.4), toxic agents in other industries (Z57.5), extreme temperature (Z57.6), vibration (Z57.7), other risk factors (Z57.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: Z57.31 (smoke) and Z57.39 (contaminants).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
