To validate present-on-admission (POA) status for a secondary diagnosis, what chronological comparison should the hospital coder make?
Select an answer to reveal the explanation.
Short Explanation
POA is a timeline puzzle: was it cooking at the front door or did it start after admission? Compare the admission H&P/ED story with later notes. That chronology — not the bill date — drives the indicator.
Full Explanation
POA assignment requires determining whether a diagnosis was present at the time of inpatient admission. Coders validate by comparing documentation at arrival and admission (ED notes, H&P, admission orders) with subsequent notes that may describe hospital onset. Discharge timing, remits, or year-to-year problem lists alone do not establish POA. Accurate POA supports correct HAC and quality reporting as well as payment integrity.
