“Now may be the time for employers to look toward using an EGWP (Employer Group Waiver Plan) with a wraparound supplemental plan to provide more cost-effective prescription drug benefits. For health plans that offer their retired employees prescription drug benefits, new rules from the Centers for Medicare and Medicaid Services (CMS) make the option of an EGWP/wrap attractive as a way to achieve significant plan savings.” – Steven P. May and David M. Liner, FSA, Milliman
