Navigate to the “Estimate my Medicare eligibility & premium” section on the official Medicare website of the US Government. This resource will provide an approximation of when you may qualify for Medicare and how much your premiums might be. Should your circumstances not be reflected there, reach out to the Social Security Administration (or the Railroad Retirement Board if you receive railroad benefits) for further insights into your precise qualifications or premiums.
Typically, you become eligible for Medicare upon reaching the age of 65 or above, being a national of the United States, or a lawful permanent resident who has resided in the U.S. for a minimum span of five years. Eligibility also rests on having contributed to the Medicare system through employment for 10 years. Those under the age of 65 might be eligible if they have a disability or certain health conditions.
