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 Humana plans generally rely on networks of doctors and hospitals and may require prior authorization or referrals for some services. Unlike Original Medicare, every Medicare Advantage plan has a yearly out-of-pocket maximum for covered medical care. You continue to pay your Part B premium, along with your plan’s premium if there is one.

Part D drug coverage is included in most Humana Medicare Advantage plans. Every plan has its own formulary, drug tiers and pharmacy network, and plans often charge less through mail order and at preferred pharmacies. In 2027, the Part D deductible on any plan can be as high as $700, and out-of-pocket costs for covered drugs are capped at $2,400.

Each plan sets its own tiers. Review every plan’s formulary.

If your Humana plan won’t be available in your county for 2027, a non-renewal notice should have arrived in early October. Your coverage doesn’t end immediately: it runs through December 31, 2026, which gives you time to decide.

Special Needs Plans (SNPs) are Medicare Advantage plans designed for particular groups. Their benefits, networks and drug lists are shaped around the members they serve, and many come with care coordinators. In 2027, SNPs are one of the few places large insurers are adding plans, even while cutting PPOs.

When you turn 65 in 2027, you get a seven-month Initial Enrollment Period: the three months before your birthday month, the birthday month itself and the three months that follow. If you sign up in the first three months, coverage begins on the first day of your birthday month.

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.

When your income and savings are limited, two programs can greatly lower your Medicare costs:

If you qualify for both Medicare and full Medicaid, you may also be able to join a Dual Special Needs Plan. See help for low-income Part D beneficiaries.

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.
