42 U.S.C. § 1382h: Benefits for individuals who perform substantial gainful activity despite severe medical impairment

such individual continues to have the disabling physical or mental impairment on the basis of which such individual was found to be under a disability; and the income of such individual, other than income excluded pursuant to section 1382a(b) of this title , is not equal to or in excess of the amount which would cause him to be ineligible for payments under section 1382 of this title and such individual meets all other non-disability-related requirements for eligibility for benefits under this subchapter. The Commissioner of Social Security shall make a determination under paragraph (1)(A) with respect to an individual not later than 12 months after the first month for which the individual qualifies for a benefit under this subsection. such individual continues to be blind or continues to have the disabling physical or mental impairment on the basis of which he was found to be under a disability and, except for his earnings, meets all non-disability-related requirements for eligibility for benefits under this subchapter; the income of such individual would not, except for his earnings and increases pursuant to section 415(i) of this title in the level of monthly insurance benefits to which the individual is entitled under subchapter II that occur while such individual is considered to be receiving supplemental security income benefits by reason of this subsection, be equal to or in excess of the amount which would cause him to be ineligible for payments under section 1382(b) of this title (if he were otherwise eligible for such payments); the termination of eligibility for benefits under subchapter XIX would seriously inhibit his ability to continue his employment; and such individual’s earnings are not sufficient to allow him to provide for himself a reasonable equivalent of the benefits under this subchapter (including any federally administered State supplementary payments), benefits under subchapter XIX, and publicly funded attendant care services (including personal care assistance), which would be available to him in the absence of such earnings. Determinations made under paragraph (1)(D) shall be based on information and data updated no less frequently than annually. In determining an individual’s earnings for purposes of paragraph (1)(D), there shall be excluded from such earnings an amount equal to the sum of any amounts which are or would be excluded under clauses (ii) and (iv) of section 1382a(b)(4)(B) of this title (or under clauses (ii) and (iii) of section 1382a(b)(4)(A) of this title ) in determining his or her income. qualifies for a benefit under subsection (a), or meets the requirements of paragraph (1); and was eligible for medical assistance under the State plan approved under subchapter XIX in the month immediately preceding the first month in which the individual qualified for a benefit under such subsection or met such requirements, Subsection (a)(2) and section 1383(j)(2)(A) of this title shall not be construed, singly or jointly, to require more than 1 determination during any 12-month period with respect to the continuing disability or blindness of an individual. The Commissioner of Social Security and the Secretary of Education shall jointly develop and disseminate information, and establish training programs for staff personnel, with respect to the potential availability of benefits and services for disabled individuals under the provisions of this section. The Commissioner of Social Security shall provide such information to individuals who are applicants for and recipients of benefits based on disability under this subchapter and shall conduct such programs for the staffs of the district offices of the Social Security Administration. The Secretary of Education shall conduct such programs for the staffs of the State Vocational Rehabilitation agencies, and in cooperation with such agencies shall also provide such information to other appropriate individuals and to public and private organizations and agencies which are concerned with rehabilitation and social services or which represent the disabled.
