A: Medicare does not have spousal or dependent coverage. Medicare is individual. If your spouse has reached age eligibility (65), then they can enroll in Medicare of their own accord 90 days in advance of the month they turn 65.
A: Part “A” is typically in place, and a paid-up benefit when you turn 65. Part “B” is not, unless you have enrolled in Social Security prior to age 65. If you have not filed to receive Social Security benefits, then you need to proactively enroll in Part “B” benefits and begin paying for them.
A: In addition to having a huge gap in coverage, you will likely face a penalty from Medicare. A Part “B” penalty can be 10% of your Part “B” premium for each 12-month period outside of Medicare, and up to 1% of the national average of a Part “D” plan for each month absent Part “D”.
