5 CFR §890.1010

1. (a)Prior adjudication is dispositive. Evidence indicating that a provider was formally adjudicated for a violation of any type set forth in 5 U.S.C. 8902a(b) fully satisfies the standard of proof for a mandatory debarment.
2. (b)Debarring official's decision. The debarring official shall issue a written decision, based on the entire administrative record, within 30 days after the record closes to receipt of information. The debarring official may extend this decision period for good cause.
3. (c)No further administrative proceedings. The debarring official's decisions regarding mandatory debarment and the period of debarment are final and are not subject to further administrative review.
