Questions About Z59.5Overview

Is Z59.5 (Problems related to housing and economic circumstances) a billable code?

Can Z59.5 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because extreme poverty describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z59.5 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for extreme poverty on inpatient claims.

Under the General Equivalence Mappings, extreme poverty converts to ICD-9-CM V60.2 (economic problem). The mapping is approximate, so confirm the match fits the documentation.
