Any individual dissatisfied with any determination under subsection (a), (b), (c), or (g) shall be entitled to a hearing thereon by the Commissioner of Social Security to the same extent as is provided in section 405(b) of this title with respect to decisions of the Commissioner of Social Security, and to judicial review of the Commissioner’s final decision after such hearing as is provided in section 405(g) of this title.
Each State which is making disability determinations under subsection (a)(1) shall be entitled to receive from the Trust Funds, in advance or by way of reimbursement, as determined by the Commissioner of Social Security, the cost to the State of making disability determinations under subsection (a)(1). The Commissioner of Social Security shall from time to time certify such amount as is necessary for this purpose to the Managing Trustee, reduced or increased, as the case may be, by any sum (for which adjustment hereunder has not previously been made) by which the amount certified for any prior period was greater or less than the amount which should have been paid to the State under this subsection for such period; and the Managing Trustee, prior to audit or settlement by the Government Accountability Office, shall make payment from the Trust Funds at the time or times fixed by the Commissioner of Social Security, in accordance with such certification. Appropriate adjustments between the Federal Old-Age and Survivors Insurance Trust Fund and the Federal Disability Insurance Trust Fund with respect to the payments made under this subsection shall be made in accordance with paragraph (1) of subsection (g) of section 401 of this title (but taking into account any refunds under subsection (f) of this section) to insure that the Federal Disability Insurance Trust Fund is charged with all expenses incurred which are attributable to the administration of section 423 of this title and the Federal Old-Age and Survivors Insurance Trust Fund is charged with all other expenses.
All money paid to a State under this section shall be used solely for the purposes for which it is paid; and any money so paid which is not used for such purposes shall be returned to the Treasury of the United States for deposit in the Trust Funds.
In the case of individuals in a State which does not undertake to perform disability determinations under subsection (a)(1), or which has been found by the Commissioner of Social Security to have substantially failed to make disability determinations in a manner consistent with the Commissioner’s regulations and guidelines, in the case of individuals outside the United States, and in the case of any class or classes of individuals for whom no State undertakes to make disability determinations, the determinations referred to in subsection (a) shall be made by the Commissioner of Social Security in accordance with regulations prescribed by the Commissioner.
