(a) CMS may at any time require an HHA to make a specific showing of being in compliance with the requirements of this Subpart F and may require the HHA to submit such additional evidence as CMS considers sufficient to demonstrate the HHA's compliance.

(b) If requested by CMS to do so, the failure of an HHA to timely furnish sufficient evidence to CMS to demonstrate compliance with the requirements of this Subpart F is sufficient for CMS to terminate the HHA's provider agreement under § 489.53(a)(1) or to refuse to enter into a provider agreement with the HHA under § 489.12(a)(3), as applicable.
