Questions About Z59.861Overview

Can Z59.861 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because financial insecurity, difficulty paying for utilities describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z59.861 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 financial insecurity, difficulty paying for utilities on inpatient claims.
