ptsd PTSD claim no CNP Denied possibel CUE and New Evidence ie buddy statement and diagnosis

[KDM]

I was diagnosed with PTSD and sent to  the PTSD clinic in Montrose NY Sept 0f 2015  they never let anyone into that clinic unless they are diagnosed with PTSD and they believe (the unit) that it may be service connected

I filed a claim in Aug of 2015 and was denied in Jan 2016 although I never saw paper work on denial SSOC I was granted zero percent for a migraine.

1. They never granted me a CNP although (question do they have to give you a CNP) although the regional office asked for one it was never scheduled

2. I found out they never reviewed my information from the PTSD unit and since then I have a Buddy statement from a shipmate and have asked for a reconsideration of the denial decision based on new and material evidence is this also a CUE? I filed this reconsideration as a homeless vet and FDC estimate on the time frame please
