The lawyer can give you some advice and, if his/her rates past the initial consultation are acceptable, help you fight back!
I don't think being on dialysis is an automatic qualifier for SSDI, if you are able to make a " gainful " amount of money working , you would not qualify. SSDI is income based as well as being based on a disability. Being on dialysis automaticity makes you eligible for Medicare right away. For SSDI you have to be completely unable to work for 5 months to qualify, then you get the first check on the 6 th month. The ticket to work is a tricky program , if you make more than the allowable amount, it's counted as a " gainful " month of employment. The months don't have to be in a row and I don't think they start counting over each year. I believe it's 6 "gainful " months that they need to disqualify a person. I haven't read anything about this subject recently but think it is still pretty much the same rule. I think the amount you can make goes up every year or two. I did do some extensive research on this a while back, if I am wrong please tell me.
When you start dialysis your clinic files a form with medicare cms2728 https://www.cms.gov/Medicare/CMS-Forms/CMS-Forms/Downloads/CMS2728.pdf This form is accepted by Social Security as evidence of having ESRD and being on dialysis. You could get a copy of this form from your clinic and submit it with your application or drop it off at your local SSA office. Thats what I did. Of course you have to meet the non medical requirements for SSDI which are having the work credits and being a U.S. citizen. If you lack the work credits you can qualify for SSI which is a needs based program.
