After three months in the gathering of evidence phase, I started doing some research. I called a couple of providers I listed on the 21-4142 I sent my regional office. I learned that those providers have not received a request for my medical records to support my claim. Ebenefits read evidence requested is past due. HOWEVER, the regional office had never requested any medical records from those providers. I sent a certified letter to the regional office a week ago stating that fact, and I see they have re-started the gathering of evidence phase. I know every case is different. But if you've been waiting a long period in that phase, ensure your providers have received a request for evidence to support your claim. Especially when you have the dreaded 'evidence requested is past due' message. Good luck to all!
