I have a question, I am retiring and the main things I am claiming are hearing loss/tinnitus, lumbago(lower back pain), and pertygium with vision loss. If I were to say get rated at 20% would i get the money or do they subtract it from my retirement pay and make it not taxable? Like say I get $200 for 20%. It would be better to get cash in my opinion. I know 50% they get a payment but what about 20%. I don't think i will get close to 50%. My fault for staying in shape..haha. But seriously, I am confused about this. I though they changed the law(concurrent reciept). Thanks
