The law requires us to conduct a disability redetermination within one year of the
SSI recipient's 18th birthday or, in lieu of a CDR, whenever we determine that an
age-18 redetermination was required but was not performed.
The field office (FO) must make every effort to initiate an age-18 redetermination:
prior to the recipient’s attainment of age 19; or
later if an age-18 redetermination was not performed prior to the recipient’s attainment
of age 19.
