Z59.81Housing instability, housed

Z59.81 is the ICD-10-CM diagnosis code for housing instability, housed. It belongs to category Z59 (problems related to housing and economic circumstances), 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 3 subcodes must be used instead.

Within Z59.8 (other problems related to housing and economic circumstances), Z59.81 is specifically for housing instability, housed. Related codes cover Transportation insecurity (Z59.82), financial insecurity (Z59.86), material hardship due to limited financial resources, not elsewhere classified (Z59.87) and other problems related to housing and economic circumstances (Z59.89).

To report this condition, pick the subcode that matches the documentation: Z59.811 (with risk of homelessness), Z59.812 (homelessness in past 12 months) and Z59.819 (unspecified).

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