More than 130,000 Missourians face a major change in their health care coverage. Medicare is switching its prescription drug coverage. Medicaid will no longer be providing coverage. Those who receive coverage under both plans will need to choose a new drug plan by the end of the year. Cindy Keele with the National Alliance for the Mentally ill is concerned recipients will not be able to understand the complicated letters being sent them. Keele advises recipients getting the letters to keep them. If they don’t understand the letters, they should ask a friend or even a doctor to explain them so they can choose the Medicare drug plan that best suits them.
