Good morning Roly,... I would also revisit my HMO PCP, and ask for a consult to a mental health doctor. I would try that route again. Have the MH doctor write a report to your HMO, PCP, as well a letter for you. That's my plan for my Agent Orange claim. I had to push one of my HMO MD specialists, and help him with examples of statments in support of the claim, that can be found here, or through Hadit. The important thing is, if you know you are right then fight for your proper rating.
