Medicare Part D 2008 Data Spotlight: Utilization Management

This Medicare Part D data spotlight examines three common techniques used by Medicare stand-alone prescription drug plans in 2008 to manage enrollees’ use of formulary drugs, such as quantity limits, prior authorization, and step therapy rules. This is one in a series analyzing key aspects of the 2008 Medicare Part D prescription drug plan choices.

It analyzes data from the 47 stand-alone prescription drug plans available nationwide using a sample of 169 commonly-used and high-cost prescription drugs. It finds that utilization management restrictions are more common in 2008 than in 2006, with 30% of sample drugs subject to some use restriction in 2008, up from 20% in 2006.

The analysis was conducted jointed by Jack Hoadley of Georgetown University, Elizabeth Hargrave and Katie Merrell of NORC at the University of Chicago, and Juliette Cubanski and Tricia Neuman of the Kaiser Family Foundation.
