After Parts A and B, most people choose one of two paths, and the decision shapes how you'll experience healthcare for years.
The Medigap path
Original Medicare plus a Medicare Supplement policy. You pay a monthly premium, and in exchange most of your out-of-pocket costs are covered. You can see any provider in the country that accepts Medicare — no networks, no referrals. You'll add a standalone Part D plan for prescriptions.
This path tends to fit people who travel, split time between states, want predictable costs, or have providers they refuse to lose.
The Medicare Advantage path
A private plan that replaces how you receive your Medicare benefits. Premiums are often low or zero, and plans frequently bundle dental, vision and hearing. The trade: provider networks, prior authorizations, and an out-of-pocket maximum you could reach in a bad health year.
This path tends to fit people who stay local, whose doctors are in-network, and who prefer a lower monthly cost while accepting more cost-sharing when care happens.
The one-way door most people miss
When you first enroll in Medigap, you generally can't be turned down or charged more for health conditions. Later, in most states, you can be. Moving from Advantage back to Medigap after your window closes may require medical underwriting — which makes the first decision more permanent than it looks.
Run the comparison with your actual doctors, prescriptions and travel habits before choosing. That's exactly what a no-cost consultation is for.
