About Z58

Z58 is the ICD-10-CM diagnosis code for problems related to physical environment. It belongs to 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.

To report this condition, pick the subcode that matches the documentation: Z58.6 (supply) and Z58.8 (environment).

The conditions in its Excludes2 note aren't part of Z58, but may be coded alongside it if the patient has both: occupational exposure (Z57.-).

It was added in FY2022, effective October 1, 2021.
