Medicare is a federally funded insurance program for eligible participants 65 or over. Medicare has two parts, Part A (Hospital Insurance) and Part B (Medical Insurance). Medicare does not cover 100% of all costs. CDI recommends purchasing a Medicare Supplement Insurance policy if you have traditional Medicare to help offset your health care costs. If you have questions related to Medicare, contact Medicare or your local Department of Aging (HICAP).
