Enrolling in Medicare

[haele]

13. I did that last year. Has to enroll to keep my Tricare for life

Here's the issue. You are required to enroll in Medicare, but you can put off paying for it if you're working and it's going to be too expensive to have both your workplace insurance and Medicare. However, once you retire and stop getting your work insurance, you will need to pay back the time you weren't paying after you turned 65.
Which, if you plan to stay employed to get max SSI or Pension/TSP, ect...might end up close to $10k or more, depending on how much they determined your income would bear.

My situation is such that I need to pay $157 a month for my Medicare to keep my Tricare for Life, which so far has paid everything for me (severe arthritis, old age problems in general) that my Aetna Health and United Concordia Dental/Vision doesn't. My younger spouse and grandkids still get the Tricare, it's just an additional cost for me.
