2011 Medicare Plan Star Ratings
·       The Medicare Plan Finder web site provides tools to help beneficiaries compare Medicare health plans with or without prescription drug plans, and stand-alone prescription drug plans.  It includes Medicare Plan Star Ratings, which measure plan quality and performance.  This information will help beneficiaries choose a plan that meets their specific needs. 
·       Plans receive a star rating for each category and every individual measure within the category. A contract can get ratings between one to five stars:
*                    means poor performance
* *               means below average performance
* * *          means average performance
* * * *      means above average performance
* * * * *  means excellent performance
·       Additionally, health and drug plans receive an “Overall Plan Rating” that summarizes all category measures into a single rating: one for health plans, one for health plans with prescription drug coverage, and one for stand-alone prescription drug plans. This overall rating includes half-stars to provide more differentiation between contracts.
