What is Joe's Medicare Part A eligibility date if he turns 65 on October 25 and stops working on that day?

Joe's Medicare Part A eligibility date is October 1 because Medicare coverage typically begins the first day of the month in which the individual turns 65. Since Joe turns 65 on October 25, even though he stops working on that same day, the eligibility for Medicare Part A is effective on the first day of the month in which he reaches that age. This ensures continuity of health coverage as individuals transition into retirement or a new phase of their lives, and it aligns with the standard Medicare enrollment timeline. Therefore, by turning 65 in October, Joe is eligible for Medicare starting on October 1.
