5 CFR §890.1036

1. (a)Presenting information and arguments to the suspending official. A provider may submit documents and written arguments in opposition to the suspension, and may appear personally, or through a representative, before the suspending official to provide any other relevant information.
2. (b)Specific factual basis for contesting the suspension. The provider shall identify specific facts that contradict the basis for the suspension as stated in the suspension notice. A general denial of the basis for suspension does not raise a genuine dispute over facts material to the suspension, and the suspending official shall not give such a denial any probative weight.
3. (c)Mandatory disclosures. Any provider contesting a suspension shall disclose the items of information set forth in § 890.1023(c). Failure to provide such information completely and accurately may be a basis for OPM to initiate further legal or administrative action against the provider.
