Medicare Improperly Paid Millions of Dollars for Unlawfully Present Beneficiaries for 2013 and 2014 

The Centers for Medicare & Medicaid Services (CMS) had policies and procedures to ensure that payments were not made for Medicare services rendered to unlawfully present beneficiaries in accordance with Federal requirements, but it did not always follow those policies and procedures. When CMS's data systems indicated that at the time a claim was processed the beneficiary was unlawfully present, CMS had policies and procedures to prevent payment for Medicare services, and CMS followed those procedures.
