What is one of the CMS settlement factors to consider during self-disclosure?

The correct choice focuses on "the cooperation in providing additional information" as a significant factor in CMS settlements related to self-disclosures. This aspect is crucial because cooperation can demonstrate a good faith effort to resolve potential issues related to compliance and fraud. When a disclosing party is willing to provide additional information, it helps CMS to assess the situation more accurately and may lead to a more favorable outcome in the settlement process. This willingness can also reflect the disclosing party's commitment to transparency and ethical conduct, factors that are highly valued in settling compliance issues.

In the context of self-disclosure, cooperation can significantly influence the tone of the negotiations and the ultimate resolution of any compliance or fraud allegations. The more transparent and forthcoming the disclosing party is, the more likely it is that CMS may look favorably upon their efforts.
