Questions About Z86.711Overview

Can Z86.711 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because personal history of pulmonary embolism describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z86.711 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 personal history of pulmonary embolism on inpatient claims.
