En español | Being in a domestic partnership means living as a couple with a person of the same or opposite sex without being formally married. In this situation, many people receive health insurance from their partner’s employer and assume that they can continue to do so after becoming Medicare-eligible, just like married people can. That is not so, except in the following circumstances:
If you do not meet these conditions, you will not be entitled to a special enrollment period to sign up for Part B without penalty when your partner’s employment ends. Instead, you should sign up during your seven-month initial enrollment period.
Note that couples of the same sex who are legally married under the laws of their state or country have the same rights as any married couples, anywhere in the United States. This includes the right to delay Part B and use a special enrollment period to sign up without penalty when coverage from their spouse’s employment ends — provided that the coverage is primary.
