Question:

I'm rated at 80% but get 100% TDIU between PTSD and IHD. My question is: Should I go for 100% because I had an ICD implanted at a VA hospital in June of 2017 or should I leave things as they are? Thanks.

Jim's Reply:

You should file for the AICD but first you need to study a bit more about your rating. 
 

You are already at 100%. The TDIU rating is a 100% rating equal to the schedular 100% rating in every way other than that you aren't allowed to work full time. Otherwise there is no difference.
 

So you're already at 100% with IHD and then you have an AICD implanted for a service connected condition...the IHD. When you have one service connected rating of 100% and you add another rating of 60% or greater, that takes you into the SMC (Special Monthly Compensation) ratings and more money each month.
 

I hate it that you're telling me you had the implant in 2017 because you can't go back and collect the dollars you've missed out on by not filing a claim. In any case, you should proceed to filing the claim now, at the first opportunity.
