Sun Life Financial Now Offers Stop-Loss Customers Access to CIGNA LifeSOURCE Transplant Network

The Employee Benefits Group division* of Sun Life Financial Inc. (NYSE: SLF, TSX: SLF) today announced that it is offering its Medical Stop-Loss customers access to the CIGNA LifeSOURCE Transplant Network^® for organ and bone marrow transplants. The CIGNA LifeSOURCE Transplant Network includes more than 400 transplant programs at over 115 nationwide transplant centers that meet stringent quality and cost management requirements.

"In today’s economy, many employers are struggling to maintain their employees’ health plans,” said Michael E. Shunney, Senior Vice President and General Manager, Employee Benefits Group. "We’re pleased to select CIGNA LifeSOURCE, which gives our customers access to some of the nation’s top transplant facilities at highly competitive rates. In health care, better outcomes can result in higher quality care and lower costs. With CIGNA LifeSOURCE, patients can gain access to highly experienced surgical teams at the network’s facilities. It’s a great example of a value-centric approach to health care that can really make a difference in our customers’ bottom line.”

CIGNA LifeSOURCE is the latest addition to SunExcel^®, Sun Life’s Centers of Excellence program. SunExcel connects Stop-Loss customers, who self-fund their employee health care plans, to Centers of Excellence that specialize in complex procedures like transplants, heart surgery, and kidney dialysis. A voluntary program, SunExcel is available to all Stop-Loss customers and their Third Party Administrators (TPAs) at no additional cost. SunExcel is part of the SunResources^® cost-containment program, which connects Sun Life’s Stop-Loss customers to a wide range of money-saving networks and services, in order to lower the total cost of self-funding.

"The agreement with Sun Life Financial marks another milestone for CIGNA LifeSOURCE,” said Ryan Johnson, national sales director of CIGNA LifeSOURCE. "We are excited to be part of the SunExcel^® program and look forward to working with Sun Life’s customers to demonstrate our capabilities and the strength of our transplant network.”
