CMS Pub. 100-18, ch. 9, § 50.6.10
Special Investigation Units (SIUs)
(Chapter 21 - Rev. 109, Issued: 07-27-12, Effective: 07-20-12; Implementation: 07 20-12)
42 C.F.R. §§ 422.503(b)(4)(vi)(F), 423.504(b)(4)(vi)(F)
An effective program to control FWA includes policies and procedures to identify
and address FWA at both the sponsor and FDR levels in the delivery of Parts C and
D benefits. An SIU is an internal investigation unit, often separate from the
compliance department, responsible for conducting surveillance, interviews, and
other methods of investigation relating to potential FWA. Depending upon the size
of and resources available within the organization, sponsors must either establish a
specific SIU or ensure that responsibilities generally conducted by an SIU are
conducted by the compliance department. Sponsors are not expected to perform
law enforcement activities and may refer all matters indicative of FWA to the NBI
MEDIC or law enforcement.
SIU responsibilities should include:
• Reducing or eliminating Medicare Parts C and D benefit costs due to FWA;
• Reducing or eliminating fraudulent or abusive claims paid for with federal
dollars;
• Preventing illegal activities;
• Identifying enrollees with overutilization issues;
• Identifying and recommending providers for exclusion, including those who
have defrauded or abused the system to the NBI MEDIC and/or law
enforcement;
• Referring suspected, detected or reported cases of illegal drug activity,
including drug diversion, to the NBI MEDIC and/or law enforcement and
conducting case development and support activities for NBI MEDIC and law
enforcement investigations; and
• Assisting law enforcement by providing information needed to develop
successful prosecutions.
SIUs must be accessible through multiple channels such as via phone, email,
Internet message submission, and mail. Sponsors must ensure that suspicions of
FWA can be reported anonymously to the SIU.
Sponsors must ensure that the SIU and compliance department communicate and
coordinate closely to ensure that the Medicare Parts C and D benefits are protected
from fraudulent, abusive and wasteful schemes throughout the administration and
delivery of benefits, both at the sponsor and FDR levels.
