Describe the type of medical insurance coverage you have. If you are not insured, describe the policy held by someone you know, or access the website of the Medicare program (Medicare.gov) and click the tab"What Medicare Covers" before answering the following questions. According to the plan's policy information (often printed in a pamphlet that accompanies the policy itself or available online at the plan's website), what benefits does the policy cover? Are some services excluded from coverage? Are any preventive medical services included?
