In short

Original Medicare lets you see any doctor that takes Medicare.
An Advantage plan is private. It often has a network.
You need Parts A and B to join one.

What this means

Medicare.gov describes two main ways to get Medicare. With Original Medicare, you pay for services as you get them. You can see any doctor or hospital that takes Medicare, anywhere in the U.S. [1]. With Medicare Advantage, you join a plan from a private company that Medicare approves.

In many cases you can only use doctors in the plan's network [1]. Most Advantage plans add extra benefits, like vision, hearing and dental [1]. You must have both Part A and Part B to join one [1].

Your next step

Compare the two options on Medicare.gov: Original Medicare lets you see any doctor or hospital that takes Medicare, and in many cases an Advantage plan limits you to its network [1]. The sources give no deadline.
