I just got approved for disability for mental reasons and the date of onset that ssa established is 6/2011. I had a workers comp claim and a one time settlement for a job injury that happened in 2007 I got the lump payment in 2008. That was 3 years before my disability began for a totally different reason. So the question is will that one lump payment that happened BEFORE my disability onset date affect my back check or monthly payments? When I got approved last week they gave me amounts for both but they ended up being way off because for some reason ssa was under the impression I was getting monthly workers comp payments through and past my onset date. With that not being the case and which they know that now since they have new documents from that comp case that should raise my amounts? They are recalculating and getting back with me Friday to finalize.
