Social Security Disability (SSDI) lawyers specialize in helping applicants get benefits, especially after having been denied. “Disability” is defined as the “inability to engage in any substantial gainful activity by reason of any medically determinable physician or mental impairment which can be expected to last for a continuous period of not less than 12 months or result in death.” This benefit is only available to those who are under the age of 65, since 65 is the age when most are allowed to collect social security retirement benefits. Most applications for disability are denied in the first stage. Therefore it is worth considering the value of having the advice and services of an attorney from the very beginning. When serious illness is affecting a person’s ability to work, it may also impact the energy available to wage a battle with the Social Security Administration. SSI is a different program and stands for “Supplemental Security Income.” It is similar to SSD or SSDI but the biggest distinction between the two is the number of work credits earned. Someone who is receiving SSD has worked most of their life and has enough credits to qualify. SSI is generally someone who has had nearly no ability to work and does not have enough credits to receive benefits under the “disability” program. Generally, a person on SSI also has no assets, such as a home.
