A listed impairment is a physical or mental condition that automatically qualifies for a disability under the Social Security Administration’s rules.
If your condition meets or equals a listed impairment, it still must last or be expected to last 12 months. Once it is found that a claimant’s medical condition equals or meets a listed impairment, the Administration will find that claimant disabled without any consideration for age, education, or past work experience.
The listing of impairments can be found in what is called the Social Security’s “Blue Book” which is broken down into adult listings “Part A” and child listings “Part B”.
