The Social Security Act was passed by Congress, and is the source of retirement benefits. In the 1970s, it was amended to include disability benefits, and then, what is called “supplemental security income” (Title XVI) to cover “disabled” people who don’t have the requisites earnings to be entitled to “Title II” benefits. The Act is implemented by Regulations passed by the administrative body known as the Social Security Administration, which used to be part of Health & Human Services, but is now an independent agency. The interpretation of its regulations is promulgated by its Rulings. The Act and the Regulations (insofar as the regulations are consistent with the Act) are binding on the courts, not only the Administration. The Rulings are not binding on the courts.
I use “disabled” in quotation marks, because it has a special meaning under the Act. (Whenever I refer to the Act, I’m also including the corresponding regulations.) In order to be “disabled” one must be so “disabled” for 12 continuous months or have an impairment which resulted in death before that time. This eliminates all of the acute disorders, which resolve within 12 months.
To be “disabled” there is a “sequential evaluation” which includes five steps. (1) Engaging in substantial gainful activity (sga), you cannot be “disabled.” If you engaged in sga within 12 months you will usually be found not “disabled.” There are exceptions involving a trial work period after five months, but I’m not going to go into all the technical details. (2) Not “severe,” as that term is defined in the Act, you’re not “disabled.” “Severe” means significant limitations on the ability to work. (3) Impairment meets a Listed impairment in the Listing of Impairments, you will automatically be found “disabled.” There are listings for impairments which involve over a dozen generic types of disorders, such as osteoarthritis, rheumatoid arthritis, blindness, cardiac problems, systemic disorders, mental impairments, etc. (4) If the impairment does not meet a Listing, you will be found “not disabled” if you can return to the requirements of your “relevant past work” as that term is defined in the Act. (5) If you are unable to return to the type of work you did within the vocationally relevant past (last 15 years) and you cannot make a vocational adjustment to other work considering your education, age, vocational factors, and your “residual functional capacity” then you will also be found “disabled.” So you will be found “disabled” if (1) the impairment or combination of impairments meets a Listing, or (2) you cannot return to your past work, and you cannot make a vocational adjustment to other work.
If your impairment(s) is only exertional, the Admn has enacted regulations in a grid fashion, establishing whether you are disabled at step five, which is dependent upon the factors I noted. That grid was upheld by the US Supreme Court as being constitutional, since it is based on data supporting it. If you have a “severe” non-exertional impairment, a vocational expert must be used at the hearing.
Which brings us to the hearing. After you file your application, a determination is made by a state agency whether you are “disabled.” If the determination is unfavorable, you can request a reconsideration by the state agency. If that too is unfavorable, you can request a hearing before an administrative law judge. If that too is unfavorable, you can appeal to the Appeals Council. That is the last step in this administrative process. Having exhausted your administrative review, you can now, and only now, file a suit in the appropriate District Court. (The Commissioner of Social Security is the defendant, so it must be brought in a federal court.)
So, under Social Security, there is no such thing as “partially disabled” or “totally disabled.” You are either “disabled” or not. Disability benefits will be that you would have if you were able to retire, computed as if you were age 62. (20% reduction - 5/9% a month from age 65 [36 x 5/9 = 20%)
