Option 1 is to get an Attorney, which sounds like it failed due to the low value of your case.
Option 2 is to accept the Compromise money, and take responsibility for your future treatment.
Option 3 is to reject the Compromise money, ask for a Stipulation settlement, and leave your Future Medical treatment open.
If you are concerned about future treatment expense, I would suggest Option 3.
We offer general concepts, but you should give ALL your facts to a licensed Attorney in your state before you RELY upon any legal advice.
You need to hire an attorney to review the file and the QME report which may be flawed. there are a few ways to attack your matter. the age of your case shouldn't make much difference in an attorney taking the case, unless you had prior counsel for those period of years.
I don't think your case is too old for an attorney to take. I would have problems taking it because you say you don't want to settle the case. If you want to leave things as they are, you don't need or want an attorney. Why would I take that case? What would you want me to do?
Consider, however, that you may be entitled to some $$ from the insurance company and you can settle for that PLUS continuing medical coverage. That's better than what you have now. Rather than settling by Compromise and Release (lump sum with no medical) ask about a Stipulations with Request for Award (less money but continuing medical care).
Despite what you may have been told by an insurance adjuster, a QME's opinion isn't controlling and there may be issues to flush out. I really doubt the age of your case is preventing attorneys from taking your case. There may be other issues. Keep trying and someone will probably take the case. Or, discuss with an Information and Assistance officer at your local District Office.
