SSR 82-52 Titles II and XVI: Duration of the Impairment
To receive benefits from Social Security, at a minimum, you will need to have at least one severe impairment which lasts twelve consecutive months, or be expected to result in death, or is expected to last twelve months.
Severe impairments lasting less than twelve months cannot be combined with successive, unrelated impairments to meet the duration requirement. For example, if you break you back and are disabled from January 1, 2012 and it heals by September 30, 2012, that back injury cannot be combined with gastrointestinal hemorrhaging which starts June 1, 2012 and goes away by March 31, 2013. Although you are disabled for more than one year, Social Security will not pay benefits.
In order to prove twelve consecutive months of disability, it is of the utmost importance to seek treatment regularly.
