How Medicare Advantage Works

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.

Feature	HMO	PPO
Out-of-network care	Not covered except emergencies and urgent care	Covered at a higher cost
Referrals for specialists	Usually required	Usually not required
Premiums	Usually lower	Usually higher
Out-of-pocket maximum	In-network limit	In-network limit plus a higher combined limit
Best for	Lower costs, local care	Flexibility, travel, keeping specific doctors

Humana Drug Coverage for 2027

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.

Tier	Typical Drugs	Typical Cost
Tier 1	Preferred generics	Lowest copay
Tier 2	Generics	Low copay
Tier 3	Preferred brand-name drugs	Moderate copay
Tier 4	Non-preferred drugs	Higher copay or coinsurance
Tier 5	Specialty drugs	Highest coinsurance

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

A drug you take may not be on a plan’s 2027 formulary, or it may come with a rule such as prior authorization. Even then, you have options:

If Your Drug Is Not Covered

Request a transition fill. During the first 90 days of a new plan or plan year, plans generally have to provide a temporary supply of a drug you already take, giving you time to change drugs or ask for an exception.

Talk to your doctor about other options. A covered drug from the same class could work just as well for less money.

Ask for a tiering or formulary exception. Your doctor sends a statement explaining why you need the drug or a lower copay. Plans have to decide within set time limits.

Challenge a denial. When the plan turns you down, you have the right to appeal through several levels of review.

See steps to appeal a Medicare Part D denial.

If Your Plan Is Ending

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.

If Your Plan Is Ending

Review your non-renewal letter. It verifies that your plan is ending and lays out your choices.

Write down your doctors and drugs. Comparing replacement plans requires them.

Compare your 2027 plan choices. Look at networks, drug coverage and the out-of-pocket maximum, not only the premium.

Pick a plan by December 31 to avoid a gap. If you enroll during Annual Enrollment by December 7, your coverage starts January 1, 2027.

Rely on your Special Enrollment Period if necessary. If your plan is ending, you generally have until the end of February 2027 to make a choice.

If you take no action: on January 1, 2027, you go back to Original Medicare, and you will have no drug coverage unless you pick a Part D plan. Being without drug coverage may result in a late enrollment penalty.

Medigap rights: if your Medicare Advantage plan exits your area, you generally get a guaranteed issue right, lasting up to 63 days after your coverage ends, to purchase certain Medicare Supplement plans with no health questions.

How to Compare Humana Plans for 2027

How to Compare

Review your Annual Notice of Change. It spells out every 2027 change to the plan you have now.

Verify your doctors and hospitals. Make sure every provider is in the 2027 network, not only the 2026 network.

Review your prescriptions. Verify every drug, the tier it falls on and any step therapy or prior authorization rules.

Look at the full annual cost. Total up the premium, usual copays and drug costs, and review the out-of-pocket maximum.

Look at star ratings. Medicare scores plans on quality and service using a 1 to 5 star scale.

Sign up by December 7. Coverage under your new plan begins January 1, 2027.

2027 Enrollment Dates

Enrollment Period	Dates	What You Can Do
Annual Enrollment Period	October 15 to December 7, 2026	Join, change or drop a Medicare Advantage or Part D plan effective January 1, 2027
Medicare Advantage Open Enrollment	January 1 to March 31, 2027	In Medicare Advantage, you can change to another plan or go back to Original Medicare one time
Initial Enrollment Period	7 months around your 65th birthday month	Sign up for Medicare and choose your first plan
Special Enrollment Periods	Varies	Switch plans after events such as a move, a loss of other coverage or your plan exiting your area

Annual Enrollment is when most people make changes. If you like your current plan, no action is needed; it renews on its own. Even so, review your Annual Notice of Change, since networks, premiums, copays and drug lists can all change on January 1.

Special Needs Plans

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.

Type	Who Qualifies	What Is Different
Dual Special Needs Plan (D-SNP)	People with both Medicare and Medicaid	Coordinates both programs; costs are often very low, with extra benefits
Chronic Condition SNP (C-SNP)	People who have qualifying conditions like diabetes, heart failure or chronic lung disease	Doctors, drugs and programs designed around the condition
Institutional SNP (I-SNP)	People who live in a nursing home or need that level of care at home	Care delivered where the member lives

Turning 65 in 2027

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.

Turning 65 Checklist

✔

Enroll in Part A and Part B, unless you have qualifying employer coverage and decide to postpone Part B

✔

Choose between Medicare Advantage and Original Medicare plus Medigap

✔

Enroll in a drug plan, or a Medicare Advantage plan that includes drugs, to avoid a late Part D penalty

✔

If you go with Medigap, purchase during your six-month Medigap Open Enrollment Period

Star Ratings

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.

Using Star Ratings

✔

Ratings of 4 stars or more are generally a good indicator of quality and service

✔

A special enrollment period lets you move into a five-star plan once during the year

✔

A new plan may not have a rating yet, and that alone isn’t a bad sign

✔

Ratings reflect the plan as a whole, not how well it covers your particular doctors and drugs

Medicare Advantage or Medigap?

	Medicare Advantage	Original Medicare + Medigap
Monthly premium	Often low or $0 (2027 average $12, CMS)	Higher; varies by plan letter, age and ZIP
Doctors	Usually a network	Any provider in the U.S. that accepts Medicare
Costs when you get care	Copays and coinsurance up to a yearly maximum	Low and predictable; on Plan G, little or nothing once the Part B deductible is met
Drug coverage	Usually included	Add a separate Part D plan
Dental, vision, hearing	Many plans may include some coverage	Not included
Changing later	Every year during Annual Enrollment	Health questions in most states once your Medigap Open Enrollment Period ends

Guaranteed issue: when your Medicare Advantage plan exits your area, you can generally purchase certain Medicare Supplement plans with no health questions asked, up until 63 days after that coverage ends.

Help Paying Medicare Costs

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

Medicare Savings Programs

✔

Run by your state Medicaid office

✔

May cover your Part B premium, and in some cases deductibles and coinsurance

✔

Income and asset limits vary by state

Extra Help (Part D)

✔

Run by Social Security

✔

Lowers Part D premiums, deductibles and copays

✔

Those enrolled in a Medicare Savings Program qualify automatically

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.

Reading Your Annual Notice of Change

Check Every Line

✔

Your 2027 premium and deductible

✔

Doctor, specialist and hospital stay copays

✔

The out-of-pocket maximum

✔

Updates to your formulary, drug tiers and coverage rules

✔

Whether your doctors, hospitals and pharmacy stay in network

✔

Updates to dental, vision, hearing and other extras

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.

Special Enrollment Periods

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

You May Qualify If

✔

Your plan is leaving your area or ending

✔

You move outside your plan’s service area

✔

You lose employer or union coverage

✔

Your Medicaid status changes, or you qualify for a Medicare Savings Program or Extra Help

✔

You want to join a 5-star plan, once a year

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