Can Z82.49 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because family history of ischemic heart disease and other diseases of the circulatory system describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z82.49 exempt from POA reporting?

What is the ICD-9 equivalent of Z82.49?

Under the General Equivalence Mappings, family history of ischemic heart disease and other diseases of the circulatory system converts to ICD-9-CM V17.3 (fam hx-ischem heart dis) and V17.49 (fam hx-cardiovas dis NEC). The mapping is approximate, so confirm the match fits the documentation.
