Which group is considered eligible for Medicare under the definition of retired federal employees?

Retired federal employees of the Civil Service Retirement System are eligible for Medicare as they are part of a specific group established by the federal government. This group consists of individuals who have served in federal positions and have retired under the Civil Service Retirement System, which provides retirement benefits to federal employees. When they reach the age of 65 or meet the other eligibility criteria for Medicare, they gain access to health coverage provided by the program.

This option is notably distinct from employees of private corporations, self-employed individuals, and employees of non-profit organizations, who do not qualify under the same criteria for being considered federal retirees. Each of these groups may have their own eligibility requirements regarding Medicare, but they do not fall under the designation of retired federal employees that the question specifies. Understanding the specific qualifications for Medicare eligibility is crucial for determining health coverage options for different categories of workers.
