What Medicare Part B (medical insurance) covers

Medicare Part B covers two types of services:

  • Medically necessary services: Services or supplies that are needed to diagnose or treat your medical condition and that meet accepted standards of medical practice.
  • Preventive services: Health care to prevent illness (like the flu) or detect it at an early stage, when treatment is most likely to work best. You pay nothing for most preventive services if you get the services from a health care provider who accepts Medicare (also referred to as assignment).

*** If the hospital gets blood from a blood bank at no charge, you won't pay for replacing it. If the hospital buys blood for you, you must either pay the hospital costs for the first three units of blood you get in a calendar year or have the blood donated by you or someone else.

Monthly Part B premium: The standard Part B premium amount in  2019 is $135.50 (or higher depending on your income). However, about 3.5% of people who get Social Security benefits will pay less due to the “hold harmless” provision. Social Security will tell you the exact amount you’ll pay.
