How does Original Medicare work?

You don't automatically get Medicare when you become eligible. You must sign up.

You can enroll in Medicare during the initial enrollment period that begins three months before the month you turn 65 and ends three months after the month you turn 65.

To apply, call or visit your local Social Security office, or call Social Security at (800) 772-1213 between 7 a.m. to 7 p.m., Monday through Friday. TTY users should call (800) 325-0778.

If you have health insurance through your employer or your spouse's employer, look at your options before signing up for Part B. Please note that Part B has a monthly premium.

Ask your broker, human resources representative, or benefits administrator for help with choosing the right option for you.


Costs of Original Medicare

Part A (inpatient hospital, skilled nursing facility, certain home health and hospice care)

Most people don't need to pay monthly premiums for Part A. You won't pay a premium if you or your spouse paid Medicare taxes for at least 10 years while working.

However, you will need to help cover the cost of some fees when you receive care. These expenses come in the form of deductibles and copayments.
