The TBI is clearly noted in my SMR, but I'm not sure the documentation is there for a moderate TBI. I will be sure to ask my neurologist if he thinks the Parkinsons was caused by the TBI. How should he document it if he does?
The way I read the regs is that if you had a moderate or severe TBI and later develope parkinsons the parkinsons is considered a secondary condition. There is no mention of any time limits for manifestation like there is for the other conditions.
I'm sure not counting my chickens on this, but I have to try as the payoff is great. All they can do is tell me no.
