Good afternoon John,
I'm Doug, and I'm sorry to hear of the confusion. My goal is to provide you with excellent service today.
First of all, unless you (unwisely) try to demand to be converted from SSDI to your retirement benefit at age 62, then your benefit will not decrease in the least when you reach age 62. However, you will also not be able to collect both SSDI and retirement at the same time. Social security only pays one benefit to a person at a time. Let me explain.
Your present SSDI benefits are based on your full retirement age benefit ($2412 monthly). So you are already getting the exact amount that you will get when you reach your full retirement age of 66. And your SSDI benefits do not automatically end until you reach full retirement age. In fact your SSDI will automatically convert to your social security retirement at age 66 and the same benefit will continue to be paid to you for the remainder of your life, increasing each year that there is a cost of living increase granted.
While your social security statement does state what your early retirement benefit will be at age 62, you are not obligated to, and should not, try to take it so long as you remain disabled. When you turn 66 it will automatically switch over to retirement for you. You don't have to do anything to make that occur.
