On Dec. 29, 2007, President George W. Bush signed the multi-faceted Medicare, Medicaid, and SCHIP Extension Act of 2007. Section 111 of the bill, titled, Medicare Secondary Payor (MSP), mandated that effective Jan. 1, 2009, all Group Health Plans (GHP) or any related entity (i.e. insurer or third party administrator) serving on behalf of the GHP will be responsible for identifying and submitting "situations where the group health plan is or has been a primary plan to the program," according to Medicare.
