Premium-Free Medicare Part A Based on Age
To be eligible for premium-free Part A on the basis of age:
A person must be age 65 or older; and
Be eligible for monthly Social Security or Railroad Retirement Board (RRB) cash benefits.
An individual who is receiving monthly Social Security or RRB benefits, at least 4 months prior to turning age 65, does not need to file a separate application to become entitled to premium-free Part A. In this case, the individual will get Part A automatically at age 65.
An individual who is not receiving monthly Social Security or RRB benefits must file an application for Medicare by contacting the Social Security Administration.
Part A coverage begins the month the individual turns age 65, provided he or she files an application for Part A (or for Social Security or RRB benefits) within 6 months of the month in which he or she becomes age 65. If the application is filed more than 6 months after turning age 65, Part A coverage will be retroactive for 6 months.
NOTE: For an individual whose 65th birthday is on the first day of the month, Part A coverage begins on the first day of the month preceding their birth month. For example, if an individual's birthday is on December 1, Part A begins on November 1.
