Hello, I would like to ask about a claim that i have filed and was just denied. I filed a claim for increase on an already rated claim, the claim was first for my back, which i was rated at 40%, it has been ten years since i was first awarded the 40% and i wanted to put in for an increase due to mental depression from the back injury. I filed the increase for my back and wrote detailed accounts of depression issues. After 17 months i received the notice that the increase was denied, yet there is no mention of any depression. I feel that i may have filed the claim wrong, in that i filed for increase of my back, when i should have filed for depression, could anyone let me know if this is true, and or, if i can file an appeal on the denied claim as my back issue is the major cause for the depression, thank you so much for any help.
