Loop Through Data In Second Column Of Pivot Table

I have a pivot table with two columns: Code and Quantity. I want to loop through the Quantity column and hide all values = 0. I can do this easily by incorporating this into my code:

Code:
pt.PivotFields("Code").PivotFilters.Add _
Type:=xlValueDoesNotEqual, DataField:=pt.PivotFields("Sum of Quantity"), Value1:=0

However, I have a "(blank)" code in all pivot tables. I do this because occasionally there is no data to organize in a pivot table. Having a "(blank)" option will allow my code to work even when there's no data. Therefore, I want to keep blank visible at all times. The above code hides "(blank)", however.

The below code is what I've tried with no success.

Code:
Set pf = pt.PivotFields("code")
For Each pi In pf.PivotItems
If pi.PivotFields("Sum of Quantity").Value = 0 Then
