Federal employees historically did not have FICA coverage and did not have Medicare. When coverage became mandatory, action was never changed to provide a supplement to Medicare as an option for Federal employees who take federal health insurance. Instead of buying (and the government also paying for a significant part) a full health insurance, federal employees who have Medicare should be able to choose a Medicare supplement. This would save the government a significant amount and it would allow the employee to have good coverage without duplicating coverage with Medicare plus a full coverage health insurance.
