Members who have an HMSA plan through an employer 

Please report to your employer any changes to your name. After you update your employer, they will then notify HMSA. Because your employer is the sponsor of your health coverage, the employer is responsible for relaying changes to HMSA for essential information such as the name of an employee. Notifying your employer ensures that their records match our records. 

Members who have HMSA's Plan for Federal Employees

Changes to a subscriber's name must be reported to one of the following offices: 

• For retirees:  the Office of Personnel Management (OPM), Retirement Office.
