Auto Claim Settlement ...When Medicare is involved


I've been an USAA for a very long time and until this process have never had any issues with this company. I was involved in an accident in October of 2017 by a fellow USAA Member, and the claim has yet to be closed. We are currently at the Settlement stage and I'm being told that they need proof form Medicare that nothing has been paid out on my behalf. I have provided that information in several forms but still have yet to be provided with what additonal is needed. I originally blamed my Legal Counsel for the delay, but after hearing first hand the interaction beetween USAA and my counsel; I'm starting to feel like it will be another year before I see my settlement. Has anyone dealt with this situation before and if so how did it turn out? Any feedback with help ease some of the anxiety that I'm feeling.
