Question 1

What is the single biggest difference between Original Medicare and Medicare Advantage?

Accepted Answer

Freedom vs. structure. Original Medicare (usually paired with a Medigap supplement) lets you see almost any doctor or hospital that takes Medicare, anywhere in the country — no networks, no referrals. Medicare Advantage bundles everything into one private plan, often with a low premium and extras like dental, but you are limited to its network and many services need prior approval.

Question 2

What is the one Medicare deadline people regret missing most?

Accepted Answer

The 6-month Medigap Open Enrollment window. It opens once — when you are 65 and enrolled in Part B — and during it no insurer can deny you or charge more based on health. Miss it, and in most states insurers can medically underwrite you later.

Question 3

What does a Medigap (Supplement) plan actually do?

Accepted Answer

It fills the gaps in Original Medicare — the deductibles, coinsurance, and copays Medicare itself doesn't cover. You keep the freedom to see any Medicare provider, and the supplement makes your costs predictable.

Question 4

I'm working past 65 with employer insurance — do I have to enroll in Medicare?

Accepted Answer

Usually not, if your employer has 20+ employees and you have active coverage. You can typically delay Part B and Part D without penalty and pick them up later through a Special Enrollment Period when the job or coverage ends.
