you really ought to be addressing these questions to your attorney. He knows you and your case better than any of us here at AVVO.
Not everyone gets the 15% bump-up. This is case specific. Talk to your attorney about that. I can't imagine any scenario where you would have to repay the 15% bump-up. Once you Stip your case, you would receive any retroactive money owed to you and continuing payments until your settlement is paid out in full.
But really....talk to your attorney about this stuff.
It's highly unusual to see an injured worker have to pay money back in a case. If there is a credit against settlement that can be applied towards a settlement. In this scenario I don't quite understand the question. If you have Retroactive money due to you it will be paid. If there is a credit against your settlement because you've been paid too much or have been afvanced money that should be disclosed to you. A 15% increase comes when they do not offer you regular or modified work. A 15% decrease comes when they can offer you that work. (Within certain time limits). Often there arguments about which is the right answer in each particular case and parties end up settling on the standard number. Since every case is very Specific to the facts You want to address these questions to your attorney who Knows the details of your case Especially with the surgeries you indicate will be needed in the future.
I can't really think of a scenario where you would have to pay back the 15% additional pd, unless there's language in the settlement documents stating so - you need to ask these questions to your attorney. PD payments are usually paid bi-weekly.
