I'm a CSRS annuitant, age 66. When I turned 65 I chose to have Medicare deducted from my CSRS monthly annuity. I'm getting ready to apply for my Social Security benefit, where Medicare premiums are automatically deducted. Do I need to do anything to stop the Medicare deduction from my CSRS annuity? I talked to a CMS rep and they implied that the system(s) will automatically catch, stop the deduction from my CSRS annuity once my Social Security benefit begins.

Hi,

No. When you apply for Social Security benefits, Social Security will automatically stop deducting your Medicare premiums from your CSRS payments and instead deduct them from your Social Security benefits.

Best, Jerry
