For the risk variable criteria below, the Present on Admission (POA) code in the attached patient files is recorded as ‘N’. However, the only POA reference set used in this measure applies to AKI diagnoses in the exclusion criteria—valueset "Present on Admission or Clinically Undetermined" (2.16.840.1.113762.1.4.1147.197).

This reference set includes only ‘Y’ (Present on Admission) and ‘W’ (Clinically Undetermined) and does not contain ‘N’.

Additionally, the guidance in the specifications lists certain diagnoses, but there are no corresponding reference sets for these diagnoses.

Could you please clarify:

1. Which diagnoses should be considered for this risk variable?
2. Which POA codes should be used to correctly calculate the risk variable?

Thank you for your guidance.
