Medicare Supplement plans, without the confusion
A Medicare Supplement, also called Medigap, helps pay the costs Original Medicare leaves to you. The concept is simple. The decisions that matter are which plan level, which company, and most of all, when you enroll.
How it works
Original Medicare pays its share of your medical bills, and a Supplement helps pay some or most of what's left, depending on the plan level you choose. You keep Original Medicare as your primary coverage, which means you can see any provider in the country that accepts Medicare, with no networks and no referrals.
The tradeoff is a monthly premium that's typically higher than Medicare Advantage. In return, your costs when you actually use care are more predictable, and your access to doctors is as broad as Medicare itself.
Timing is the part people miss
When you first enroll in Part B at 65, you get a six-month Medigap Open Enrollment Period. During that window, companies must accept you regardless of your health history. After it closes, medical underwriting can apply in many situations, and a health condition could affect your options or your price.
This is the single biggest reason to understand your choices before you turn 65 rather than after. Our Turning 65 Resource Center lays out the full timeline.
Common questions
Can I use any doctor with a Medicare Supplement?
Yes. Medicare Supplement plans work alongside Original Medicare, so you can see any doctor or hospital in the country that accepts Medicare. There are no networks and no referrals.
When is the best time to buy a Medicare Supplement?
Your Medigap Open Enrollment Period starts when you're 65 and enrolled in Part B, and it lasts six months. During that window, companies can't turn you down or charge you more because of your health history. Outside that window, your health can affect approval and pricing in many cases, which is why timing matters so much.
Why are Medicare Supplement plans named with letters?
The federal government standardized them. A Plan G from one company has the same core benefits as a Plan G from another, which means you're mostly comparing price, the company's rate history, and service. That standardization makes this one of the more comparable products in insurance.
Does a Medicare Supplement cover prescriptions?
No. Supplements help with Original Medicare's out-of-pocket costs like deductibles and coinsurance. For prescriptions, you'd pair it with a separate Part D drug plan.
Comparing Supplement options?
Because these plans are standardized, an independent agency can compare companies side by side. We'll show you how the pricing works and let you decide.
