the marketplaces are not for people with medicare. you can search for a new medicare advantage plan (it sounds like that may be the type of coverage you have). open enrollment for medicare is happening now through december 7th. you can go to the medicare plan finder to search for new options at medicare. gov.
unitedhealth/medicare/medicaid are my current health insurance coverages. . i pay $380/month. any suggestions for a lower cost plan for the same benefits in 2014?
