Mainstreet Financial Education · Medicare Enrollment
Medicare's first-year decisions are the ones that follow you. Avoiding these five keeps the avoidable penalties off your premium for good.
The best windows in your first year open only once, and the late penalties never expire.
This is the seven-month window around your 65th birthday. Skip Part B without active employer coverage and you owe a 10% penalty for every year you wait, added to your premium for life.
You are enrolled automatically only if you already collect Social Security. Everyone else has to sign up on their own, on time.
With no creditable drug coverage, a late-enrollment penalty accrues at roughly 1% of the national base premium for every month you wait, and it is added for as long as you have Medicare.
A $0 premium can hide a narrow network, prior-authorization hurdles, and a high out-of-pocket limit. Check the formulary and confirm your doctors first.
Your guaranteed Medigap window is six months at 65, plus a 12-month trial right if you start on Medicare Advantage. After that, most states let an insurer turn you down based on your health.
Late penalties do not expire. The Part B and Part D late-enrollment penalties are not one-time fees. Both ride on your premium for as long as you have Medicare, which is why the first-year windows matter so much.
The first-year windows only open once.
