Medicare offers an interactive online tool called the Medicare Plan Finder that allows for comparison of coverage and costs for all plans in a geographic area. The tool lets users enter a list of medications along with pharmacy preferences and Social-Security-Extra-Help/LIS and related status. The Finder can show the beneficiary's total annual costs for each plan along with a detailed breakdown of the plans' monthly premiums, deductibles and prices for each drug during each phase of spending (initial, gap, catastrophic). Plans are required to update this site with current prices and formulary information every other week throughout the year.
