Ignoring the OIG Exclusions list could result in lost revenue for your EMS Agency. What is the OIG’s List of Excluded Individuals/Entities (LEIE)? LEIE is a published list of individuals and health care entities that the Office of Inspector General has excluded from participating in Medicare, Medicaid, and all Federal health care programs. Why it is important for EMS providers and EMS Billing Services to know who is on LEIE? Severe penalties can be imposed for employing, contracting with, or billing for items or services ordered by a person excluded from participating in federal health care programs.
