Hi Doc, I think yes you can get a true 100% but only if your employment is jeopardized! So if you got a 60% now, and get another 30%, you move up to 70% But the only reason you got the 30% on the second claim to start with is because you are still able to work. that second 30% is not significantly interfering. But if you file with a new disability that now wipes you out of work, then you would be upgraded to 100%. Same if you refile on an old one Like Carly, that wipes you out of work, the rating will change to 100%.
Yes, I see your point Doc. The odds of coming up with another diagnosis that would be rated 100% of the left over 40% are slim and you still wouldn't reach a true 100%, leaving the only option of a true 100% is if your original Ischemic disease getting worse and then you would have to re-file on your original claim. But if your original diagnosis worsens to 100%, then that is no good either with such a poor prognosis.
I'd say the VA had some pretty good accountants when they figured all this out. I wonder if they would help me with my taxes :-)
