Retirement sometimes comes with a new ZIP code; perhaps you’re moving closer to grandchildren, escaping high housing costs, or finally heading somewhere warmer. But packing boxes isn’t the only thing Medicare beneficiaries need to think about because some types of Medicare coverage are tied directly to where you live.
