How does Medicare Advantage work?

Medicare Advantage plans, also called Part C, are offered by private insurers that contract with Medicare. Instead of Medicare paying your doctors directly, the government pays the insurance company a set amount to cover your care. You still have Medicare, but your benefits run through the plan.Most Advantage plans work like an HMO or PPO. That means you may need to use a specific network of doctors and hospitals, or pay more to go outside it. Some plans require referrals to see specialists. Others give you more flexibility.The appeal is that many plans bundle in things Original Medicare does not cover, like dental cleanings, glasses, hearing aids, and Part D drug coverage. Some plans have low or even zero monthly premiums, though you still pay your Part B premium to Medicare.The tradeoff is that your costs and coverage depend heavily on the specific plan and where you live. Network restrictions, prior authorization requirements, and out-of-pocket limits vary a lot from plan to plan. A plan that works well for your neighbor may not work for you, especially if you have preferred doctors or take specific medications. Always verify current plan details before enrolling.
