I HAVE the "named condition" and the "severity of symptoms" listed in the Adult Impairments list on the Soc. Sec. website. And, I was STILL denied the first time. I got a lawyer -- who fully expected to have to take my case before a judge -- but, I was rather QUICKLY approved the second go-round via mail.
My lawyer DID say that IF your doctor(s) don't use the SPECIFIC wording that Soc. Sec. wants/expects, you can be denied. He sent forms for my doctors to fill out.
BTW, I've heard rumors of ALS patients being denied in my state -- and that is supposed to be a "for sure".
