I’m sure you’ve heard the phrase “Nothing in life is free,” and nothing is – not even Medicare. In most cases, you won’t have to pay a premium to get Medicare, at least for Part A (here’s a refresher on the different parts of Medicare), but that doesn’t mean it’s free. You’ve just pre-paid in the form of taxes. So you don’t have to worry about a premium for Part A, which covers in-patient hospital expenses, assuming you or your spouse paid Social Security for at least 10 years. However, there are other costs associated with Medicare, which vary depending on the specific insurance.
