Medicare Part B Self Pay Premium Overpayment Question
Hello: I have not yet started Social Security but am on Medicare (Basic and Part B). I am new to Medicare by a few months. I pay my Part B premium on-line (not autopay) via credit card not via Social Security. I believe I have paid my Part B Premium multiple months in advance since I mistakenly didn't wait for bill. Is there a way to see when my next Part B premium is due (how far in advance I have paid)? Will paying my Part B Premium in advance by a few months cause any issues or will medicare just apply the premium?
Thanks in advance for assistance
