5 C.F.R. § 890.1026 – Procedures if a fact-finding proceeding is not required.

(a) Debarring official's procedures. If a fact-finding proceeding is not required, the debarring official shall issue a final decision of a provider's contest within 30 days after the record closes for submitting evidence, arguments, and information as part of the contest. The debarring official may extend this timeframe for good cause.
(b) No further administrative review available. There are no further OPM administrative proceedings after the presiding official's final decision. A provider adversely affected by the decision may appeal under 5 U.S.C. 8902a(h)(2) to the appropriate U.S. district court.
