Ugh......there are so many different ways practices post these, but I'll give this a shot. First, just a little more info:
1) What practice management billing software do you use?
2) Can you give more detail on what was originally posted on the 2 charges that you had to appeal? (i.e., was a "zero" payment posted to indicate they were originally denied, did the original fees for those 2 charges remain unadjusted on the claim, etc.)
