To my understanding, the only thing that changes when you reach retirement age is where your social security payments come from; Social Security instead of Social Security Disability, and no changes are made to the amount you currently receive as that was already calculated, and taken into consideration the shortened work time, and minus any increase for cost of living lol, and deductions for Medicare, if you do receive it.
You can call SS and ask. I have about 10 more years to reach retirement age.
Here is a link from SS regarding the issue:
