Medicare Advantage, sometimes called Part C, lets you receive your Medicare benefits through a Medicare-approved private insurer. These plans cover everything Original Medicare Part A and Part B cover, with the exception of hospice care, which Original Medicare continues to pay for. Most also bundle Part D drug coverage, and many may tack on extras like routine dental, vision and hearing benefits.

The trade-off is that Medicare Advantage plans generally rely on doctor and hospital networks and may call for referrals or prior authorization for certain services. Each Medicare Advantage plan sets a yearly out-of-pocket maximum for covered medical care, something Original Medicare lacks. You still pay your Part B premium, along with the plan’s premium if there is one.

Benefits are not offered by every plan. They differ by plan and county and may change for 2027. Review the Evidence of Coverage for each plan before enrolling.

Each fall, Medicare gives every Medicare Advantage and Part D plan a rating of 1 to 5 stars, based on factors such as preventive care, how well chronic conditions are managed, member complaints, customer service and accuracy of drug pricing. You can see the ratings in Medicare Plan Finder.

A non-renewal notice should have reached you in early October if your plan won’t be available in your county for 2027. Coverage doesn’t end immediately; it runs through December 31, 2026, which gives you time to decide.

The Annual Notice of Change must reach members by September 30. It is the most useful single document you receive each fall, since it spells out exactly how your plan will change on January 1.

Outside of the fall and early-year windows, changing plans generally requires a Special Enrollment Period. Typical reasons include:

Every Special Enrollment Period has a separate time limit, so move as soon as the event occurs.

Prior authorization is required by most Medicare Advantage plans for certain services, including some surgeries, advanced imaging, skilled nursing stays and some drugs. While your doctor usually submits the request, ask whether a scheduled service needs approval so you are not caught off guard by a denial.

You or your doctor can appeal a denied request. Medicare rules give plans deadlines for decisions, and those deadlines are shorter when a wait could seriously harm your health.

Emergency and urgent care are covered by every Medicare Advantage plan anywhere in the U.S., whether in or out of network, and an emergency does not require prior approval. Routine care while traveling is different: HMOs generally do not cover it, and PPOs cover out-of-network care at a higher cost.

If you’re away from home for months each year, ask every plan how it covers care where you stay. This is among the most frequent reasons people change plans partway through the year.

You have the right to appeal if your plan denies a service, a drug or payment for care. The denial notice from the plan explains the process. Appeals have several levels, beginning with the plan and moving on to independent reviewers.

If your issue isn’t about coverage, such as wait times or customer service, you can file a grievance with your plan. For help, you can also reach out to 1-800-MEDICARE or your State Health Insurance Assistance Program.

You do not need to compare plans by yourself, and help should not cost you anything. Here are the free options:

Gather your Medicare card, a list of your drugs and doses, your doctors and your preferred pharmacies before you call. That way a long conversation becomes a quick one.
