The Centers for Medicare & Medicaid Services (CMS) announced that it is sending "Choosers Reminder Notices" to approximately 944,000 Medicare beneficiaries who are eligible for the Part D low-income subsidy (LIS). The notices, which are being mailed from May 26 – May 31, are designed to remind these individuals that the drug plan in which they are enrolled has a premium that is not fully covered by LIS, and that they may change to a plan whose premium is fully covered (a $0 premium plan) at any time. A copy of the notice is available at https://www.medicareadvocacy.org/wp-content/uploads/2011/05/ChoosersLetter.pdf.
