What is the Definition of "Disability" Under the Social Security Act?

As defined in the Social Security Act, a “disability" is the "inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or has lasted or can be expected to last for a continuous period of not less than 12 months." It’s important to understand that not everyone uses the same definition as Social Security. Your doctor, hospital, and even other governmental agencies will use different definitions, which can lead to confusion for many claimants. For example, some agencies’ definition of “disability” allows for partial disability. Social Security, however, does not provide for partial disability.

As you can see, Social Security uses a very technical and precise definition for “disability.” We can help you prove that you are disabled and unable to work.
