Medicare Advantage vs Medicare Supplement

Choosing between Medicare Advantage and Original Medicare with a Medicare Supplement policy is a decision about how you want to receive care, manage costs, and use providers. Neither path is a universal fit. The better match depends on your doctors, prescriptions, budget, travel, preferred level of cost predictability, and eligibility to buy a Medicare Supplement policy.

This guide explains the two paths without recommending one over the other. Plan availability, premiums, networks, drug formularies, and extra benefits vary by location and can change. Review the specific coverage available at your home address before enrolling.

Does Medicare move with you to another state? Original Medicare can cover care from providers who take Medicare across the United States. Private coverage needs a separate review: Medicare Advantage and Part D plans have service areas, and a Medigap policy follows different rules. Check every part of your coverage before relocating.

Every fall, Medicare gives you a window to review your coverage and make changes for the year ahead. This year's version of that window — running October 15 through December 7, 2026 — decides what your Medicare Advantage or Part D coverage looks like starting January 1, 2027. Here's what's worth knowing before it opens, and a simple way to get ready.

Medicare covers an enormous amount — hospital stays, doctor visits, most prescription drugs through Part D, and more. But there's a short list of everyday health needs it was never designed to cover, and it tends to catch people off guard right when they need it most. Here's what's actually excluded, and the common ways people handle each gap.
