Questions About Z58.81Overview

Can Z58.81 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because basic services unavailable in physical environment describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z58.81 exempt from POA reporting?
