I received a denial for frequency on L5679 after providing a new set of liners after 10 months. I am sure this has been covered on the board several times before, so I apologize for asking again. However, I need help with this. How do I fight this as the liners were needed? Also, is there a search function on OandP.com that I can utilize before asking the same question that has been asked before?
TIA
