Macro Highlight & select different value in multiple range

Hi, good morning!!

I have this macro:

Private Sub CommandButton23_Click()


Dim rnArea As range
Dim rnCell As range

Set rnArea = Sheets("sheet2").range("D9", range("D65536").End(xlUp))

  For Each rnCell In rnArea
     With rnCell
        If Not IsError(.Value) Then
      Select Case .Value
          Case "PZ"
             .Interior.ColorIndex = 45
          Case "MT"
            .Interior.ColorIndex = 20
      End Select
       End If
   End With
Next

End Sub

But I need the inverse function..
I need to highlight & select the row with different value that "PZ" & "MT".. with this macro, highlight me the cell with PZ & MT..

Thanks to help me!
Best Regards!!
