Short answer: Your enrollment window is 7 months around your 65th birthday — enroll in the first 3 months so coverage starts on time and you avoid lifelong penalties. Below: the Michigan-specific piece most guides skip.
Turning 65 in Michigan means the same federal deadline as everywhere — plus state specifics worth knowing before you choose. Here's the plain-English version.
Your 7-month Initial Enrollment Period
The window: 3 months before your birthday month, the month itself, and 3 months after. Enroll early for coverage that starts the first of your birthday month. Miss it without other creditable coverage and the Part B penalty (10% per full year delayed, for life) and the Part D drug-coverage penalty apply.
Michigan: check your retiree benefits before you touch anything
Michigan has one of the country's largest concentrations of employer and union retiree health benefits — auto-industry and public-sector retirees especially. If you have retiree coverage, how it coordinates with Medicare (and whether enrolling in other coverage could permanently forfeit it) is the first question to answer at 65 — before you sign anything.
