My 9/25/2001 claim for hypertension as a result of agent orange (AO) was denied. If hypertension is eventually added as a presumptive illness arising from AO, do I have to file a claim again? Do I rely on the VA to go back and look at my hypertension denial without some sort of notification from me?
You'll have to file a claim at the appropriate time. Never rely on VA for such things.
