Humana Medicare Advantage Plans: A 2026 Guide to Coverage and Costs

What Humana Medicare Advantage plans are

Medicare Advantage — also called Part C — is an alternative to Original Medicare offered by private insurers that contract with Medicare and must follow rules set by the Centers for Medicare & Medicaid Services (CMS). Humana is one of the largest private insurers offering these plans nationwide.

When you enroll in a Humana Medicare Advantage plan, the plan provides your Part A (hospital) and Part B (medical) benefits in place of Original Medicare. Most Medicare Advantage plans also include Part D prescription drug coverage built in, and many bundle supplemental benefits such as dental, vision, or hearing. You stay enrolled in Medicare and keep paying your Part B premium.

Plans are sold by county, so the exact networks, premiums, copays, drug formularies, and extra benefits differ from one Humana plan to the next — and from one ZIP code to the next. Nothing in a Humana plan is universal; always read the specific plan's Summary of Benefits.

What they cover in 2026

By law, every Medicare Advantage plan must cover everything Original Medicare Part A and Part B cover (except hospice, which Original Medicare continues to pay). Beyond that baseline, plans compete on cost-sharing and added benefits.

CMS expects supplemental benefit offerings — such as hearing, dental, and vision — to remain broadly available across Medicare Advantage in 2026. Whether a particular Humana plan includes a given extra, and how much it pays, varies by plan.

• Hospital and medical care (the Part A and Part B benefits) — required in every plan
• Prescription drugs (Part D) — included in most, but not all, Medicare Advantage plans
• Possible extras that vary by plan: dental, vision, hearing, fitness, and over-the-counter allowances
• Provider networks: most plans are HMOs or PPOs, so using in-network doctors and getting prior authorization for some services usually matters for cost and coverage

What you'll pay in 2026

You keep paying the standard Part B premium even on a Medicare Advantage plan: $202.90 per month in 2026, with a $283 annual Part B deductible under Original Medicare. Many Medicare Advantage plans charge little or no additional plan premium — CMS estimates the average Medicare Advantage monthly plan premium will be about $14.00 in 2026 — but a $0 plan premium does not mean $0 in costs, because you still owe copays and coinsurance as you use care.

A major protection is the annual maximum out-of-pocket (MOOP) limit, which Original Medicare does not have. For 2026, CMS caps the in-network out-of-pocket maximum at $9,250 for covered Part A and Part B services; individual plans may set a lower limit. Once you hit your plan's MOOP, the plan pays 100% of covered medical services for the rest of the year.

Two important caveats on the MOOP: Part D prescription drug spending does not count toward it, and neither do most supplemental benefits like dental. Separately, Part D itself has its own protection — a $2,100 annual cap on out-of-pocket prescription drug costs in 2026. Actual premiums, deductibles, and copays differ by plan, so compare the numbers for each specific Humana plan.

Humana Medicare Advantage vs. Original Medicare

The core trade-off is networks and rules in exchange for bundled extras and a spending cap. Original Medicare lets you see any provider in the U.S. that accepts Medicare with no referrals, but it has no annual out-of-pocket limit and no built-in drug or dental coverage.

A Humana Medicare Advantage plan typically asks you to use a provider network and may require prior authorization or referrals, but it caps your annual medical spending and often folds in drug and supplemental benefits. Which is better depends on your doctors, your medications, and how you weigh flexibility against a predictable ceiling — there is no single right answer.

• Networks: Original Medicare is nationwide; Medicare Advantage is usually network-based (HMO/PPO)
• Spending cap: Medicare Advantage has an annual MOOP; Original Medicare does not
• Drug coverage: built into most Medicare Advantage plans; a separate Part D plan with Original Medicare
• Medigap: you can buy a Medigap policy with Original Medicare, but not with a Medicare Advantage plan

When and how to enroll or switch

You can first join a Medicare Advantage plan during your Initial Enrollment Period around your 65th birthday. After that, the main window is Medicare's Fall Open Enrollment, October 15 to December 7 each year, when anyone with Medicare can join, switch, or drop a Medicare Advantage or drug plan for coverage starting January 1.

There is also the Medicare Advantage Open Enrollment Period, January 1 to March 31. If you are already in a Medicare Advantage plan, you can use it once to switch to a different Medicare Advantage plan or return to Original Medicare (and add a standalone drug plan). You cannot use this window to move from Original Medicare into a Medicare Advantage plan.

To compare specific Humana plans in your area against other options, use the official Medicare Plan Finder at Medicare.gov/plan-compare or call 1-800-MEDICARE (1-800-633-4227). Check that your doctors are in-network and your drugs are on the formulary before you enroll.
