100 P&T

I know everyone says it's permanent and can't change but maybe someone out there has a different experience. Has anyone ever been reduced from 100 P&T that uses VA Healthcare but never opened another claim after it was awarded? I got my rating about 8 months ago and only go to the VA for Healthcare. TIA

Again, I know most people are going to say that it's Permanent, I'm just wanting to know if anyone has had that experience that was 100 P&T
