The provisions of subsection (a) shall apply to any group of providers of services if each provider of services in such group would, upon the filing of an appeal (but without regard to the $10,000 limitation), be entitled to such a hearing, but only if the matters in controversy involve a common question of fact or interpretation of law or regulations and the amount in controversy is, in the aggregate, $50,000 or more.
A decision by the Board shall be based upon the record made at such hearing, which shall include the evidence considered by the intermediary and such other evidence as may be obtained or received by the Board, and shall be supported by substantial evidence when the record is viewed as a whole. The Board shall have the power to affirm, modify, or reverse a final determination of the fiscal intermediary with respect to a cost report and to make any other revisions on matters covered by such cost report (including revisions adverse to the provider of services) even though such matters were not considered by the intermediary in making such final determination.
The Board shall have full power and authority to make rules and establish procedures, not inconsistent with the provisions of this subchapter or regulations of the Secretary, which are necessary or appropriate to carry out the provisions of this section. In the course of any hearing the Board may administer oaths and affirmations. The provisions of subsections (d) and (e) of section 405 of this title with respect to subpenas shall apply to the Board to the same extent as they apply to the Secretary with respect to subchapter II.
The Board shall be composed of five members appointed by the Secretary without regard to the provisions of title 5 governing appointments in the competitive services. Two of such members shall be representative of providers of services. All of the members of the Board shall be persons knowledgeable in the field of payment of providers of services, and at least one of them shall be a certified public accountant. Members of the Board shall be entitled to receive compensation at rates fixed by the Secretary, but not exceeding the rate specified (at the time the service involved is rendered by such members) for grade GS–18 in section 5332 of title 5. The term of office shall be three years, except that the Secretary shall appoint the initial members of the Board for shorter terms to the extent necessary to permit staggered terms of office.
