There are five different POA indicators:

Y– Yes, present at the time of inpatient admission
N– No, not present at the time of inpatient admission
U -Unknown, documentation is insufficient to determine if condition is present on admission
W– Clinically undetermined, provider is unable to clinically determine whether condition was present on admission or not
E– Exempt, unreported/not used, some facilities will leave these blank, others will use the letter “E”
