80% disability but just got Pacemaker

Question:

Hey Jim!   I am a 72 combat wounded Marine Vietnam Veteran. I am rated 80% disabled. 70% PTSD, 10% Ishcehmic heart disease(Agent Orange).  I recently had a pacemaker implanted as a result of a heart rate issue.  Should I file a claim for an increase in my disability rating?

Jim's Reply:

Yes, absolutely. File and tell VA that the pacemaker is required due to your IHD. If the claim is denied, get back to me for the appeal.
