You asked:
When the Social Security Dept. does the conversion, what happens to her Medicare? Will she be able to keep it? If so, will it cost more?
-------------------------------------------------
Most likely nothing will change BUT when she turned 65 years old (the age when most people go on Medicare) - some other choice options may have opened up for her.
In many states, those less than 65 years old cannot get a Medigap policy (Medicare supplemental policy) - so until they reach the age of 65, their only choice in a Medicare Advantage plan until they reach age 65.
At that time, it is kind of like a do-over in their Medicare choice - even if they have had Medicare for many years due to their SSDI disability. At that age of 65, they can pick their Medicare choices just like they are a new enrollee.
This may or may not apply to her cause it depends on the state as to the availability of all or limited Medicare choices before age 65.
However, now that she is turning 66, this may be a mute point anyway because their are timing restrictions based on her 65th birthday. But if you are thinking this might benefit her (a Medigap plan with traditional Medicare) and she missed it - I would start filing a complaint - they should have notified her around her 65th birthday.
I came back to add to your last question on Medicare: Will it cost her more?
Most likely it will not but that depends on her income - If before her SS conversion from SSDI to SS Old Age Retirement she had Medicare and Medicaid or some other extra help - and this amount stays the same and there is no other income added - it will stay as is - meaning that she will continue to pay her Part B premiums just like the majority of us do.
To answer you more specifically you will have to tell us what she had before generally.
