Context
Who gets hit and who walks free
Group coverage tied to a job you or your spouse currently hold keeps you safe. Retiree plans, COBRA, and marketplace policies do not. Once that active work ends the clock starts, and you get eight months to pick up Part B clean.
Drug coverage carries a second, separate penalty. Thinking about delaying? Read up on Part D drug plans too, and see the full list of mistakes to avoid.
