A blank is not a zero. CMS withholds a value between 1 and 10, and withholds the next lowest alongside it so the first cannot be worked out by subtraction — so a withheld figure is not even evidence that the number was small. Rows for ten or fewer claims are removed from the file altogether, which is why the parts of a total can be withheld while the total is published.
