Part C

 You join a Medicare-approved plan from a private company that offers an alternative to Original Medicare for your health and drug coverage.

In most cases, you can only use doctors who are in the plan’s network.

• Monthly premiums vary based on which plan you join. The amount can change each year.
• You must keep paying your Part B premium to stay in your plan.
• Deductibles, coinsurance, and copayments vary based on which plan you join.
• Plans also have a yearly limit on what you pay out-of-pocket. Once you pay the plan’s limit, the plan pays 100% for covered health services for the rest of the year.
