If your doctor can’t convince the VA board that your procedure will give you a better than 70% improvement rate, then your procedure is NOT approved - PERIOD! That “70% improvement” is the MINIMUM, to get an approval at the VA!
I couldn’t get the VA to complete a REQUIRED procedure (remove screws that were installed while on active duty); they were supposed to be removed within 13 months! I had to have my personal doctor remove them...several months after the “must be removed by” date!
I’ve never met a man with a 50% or greater VA disability (Tier 1) with a single complaint on the VA.
The VA treats the Tier 1 very, very well.
