For Medicare beneficiaries seeking to change their options for 2018, the clock is ticking. Now is the time to make changes to Part C and/or Part D that better fits your health needs. But the opportunity to make any revisions will end on December 7, 2017, with one exception. If you are a survivor of the recent hurricanes (Harvey, Irma and Maria), there is a special enrollment period just for you through the end of the year. If you have other questions about Medicare, visit USA.gov.
