Component Separation in Hernia Repair

Can anyone explain to me why its not ok to bill 15734 with hernia repair codes (exp 49560,49568, & 15734,15734-59). I have seen so much contradicting information. There is so much contradiction, use it dont use it. I cant seem to find any documentation that says why its inappropriate.

Any advice would be greatly appreciated.
