Section 13.3 - Proceedings covered(a) These rules apply only to adversary adjudications. For the purpose of these rules, only an adjudication required to be under 5 U.S.C. 554 , in which the position of the Department or one of its components is represented by an attorney or other representative ("the agency's litigating party") who enters an appearance and participates in the proceeding, constitutes an adversary adjudication. These rules do not apply to proceedings for the purpose of establishing or fixing a rate or for the purpose of granting, denying, or renewing a license.(b) If the agency's litigating party enters an appearance, Department proceedings listed in appendix A to this part are covered by these rules. Also covered are any other proceedings under statutes that incorporate by reference the procedures of sections 1128(f), 1128A(c)(2), or 1842(j)(2) of the Social Security Act, 42 U.S.C. 1320a -7(f), 1320a -7a(c)(2), or 1395u(j)(2) . If a proceeding is not covered under either of the two previous sentences, a party may file a fee application as otherwise required by this part and may argue that the Act covers the proceeding. Any coverage issue shall be determined by the adjudicative officer and, if necessary, by the appellate authority on review.(c) If a proceeding is covered by these rules, but also involves issues excluded under paragraph (a) of this section from the coverage of these rules, reimbursement is available only for fees and expenses resulting from covered issues.45 FR 45252, Oct. 4, 1983, as amended at 69 FR 2845, Jan. 21, 2004
