Should I appeal my med board

I want to appeal my PEB, med board, from the marines. I was rated 10% for my leg and 0% for my PTSD. However I have been rated at 100% for Ptsd from the VA for quite some time and have even done inpatient Ptsd programs. I also have several letters from different Drs speaking of the severity of my PTSD. I have all the rating letters, the letters from Drs, and my medical records from my time in the programs.
Should I start with add form 149 application for correction of military record or should I start somewhere else?
