TN 60 (01-00)
DI 11070.005 Glossary and General Explanation of Applicable Terms
1. Age 18 Cases
For purposes of disability adjudication an individual is an adult and subject to the adult disability standards upon attainment of age 18. This is true regardless of the individual's designation for other purposes. An age 18 case is any case in which the individual was eligible in the month before the month of attainment of age 18, attained age 18 on or after August 22, 1996, and for whom a disability redetermination or its equivalent, as determined by the DDS, was not performed after the attainment of age 18. (See DI 23570.010B.1.b.)
NOTE: An age 18 disability determination is never applicable to an individual who attained age 18 before August 22, 1996.
2. Childhood (Under Age 18)
For purposes of disability adjudication a child is an individual under age 18 and is subject to the definition of disability for individuals under the age of 18. This is true regardless of the individual's designation for other purposes.
3. Comparable Severity
The prior definition of disability contained the clause “(or, in the case of an individual under the age of 18, if he suffers from any medically determinable physical or mental impairment of comparable severity)” i.e., to one which would disable an adult. SSA's prior rules defined “comparable severity” as meaning that a child's physical or mental impairment(s) so limited his or her ability to function independently, appropriately, and effectively in an age-appropriate manner that the impairment(s) and the limitations resulting from it were comparable to those that would disable an adult. SSA used an individualized functional assessment (IFA) to assess whether a child's impairment(s) was of comparable severity. (See glossary item 5, below.)
4. Disability Redetermination
Disability redetermination means a new determination of an individual's eligibility based on disability using the rules for new applicants appropriate to the individual's age, except the rules pertaining to performance of substantial gainful activity (SGA). For individuals who are working and for whom a disability redetermination is required, apply the rules in SI 02302.001 ff. concerning the work incentive provisions of sections 1619(a) and 1619(b) of the Act. In conducting a disability redetermination, the disability determination service (DDS) will not use the rules for determining whether disability continues set forth in DI 28001.001 ff. (See DDS CDR procedures).
5. Individualized Functional Assessment (IFA)
Under the prior rules, if a child's impairment was severe, but did not meet or equal in severity any of the listings in the Listing of Impairments, SSA did an IFA to determine whether the child had an impairment or combination of impairments which would nevertheless be of comparable severity to an impairment(s) that would disable an adult. SSA assessed the extent to which the child was able to function independently, appropriately, and effectively in an age-appropriate manner despite his/her impairment(s), and used this assessment to determine whether the child was disabled.
6. Maladaptive Behaviors
As defined in the prior rules (prior listing 112.02B.2.c(2)), “Persistent, serious maladaptive behavior destructive to self, others, animals, or property, requiring protective intervention.”
