I need the macro below to look first at Range BI6:BI137 and find blank cells,
then look at Range Y6:Y137 for the code information. Is that possible?

Sub Sonic()
With Worksheets("Oct 8 - 2054543")
For Each c In Range("y6:y137")
If c.Value = "A" Then
c.Offset(0, 36).Value = "No medical necessity for IP status; should
have been OP"
End If
If c.Value = "B" Then
c.Offset(0, 36).Value = "Admitted with presumed acute need;
Documentation and findings did not support IP status. Should have been OP
Observation"
End If
If c.Value = "C" Then
c.Offset(0, 36).Value = "No IP acuity documented; no complication
post procedure or acute intervention; should have been OP Surgery."
End If
If c.Value = "D" Then
c.Offset(0, 36).Value = "Patient does not meet IP guidelines; should
be OP observation"
End If
End With
End Sub
