Can Z82.1 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because family history of blindness and visual loss describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z82.1 exempt from POA reporting?
