UnitedHealthcare Medicare Advantage Plans 2027: Coverage, Costs & How to Enroll

Reviewed by Russell Noga, Licensed Medicare Insurance Broker — Last updated August 17, 2026

UnitedHealthcare is one of the largest Medicare Advantage carriers in the country, offering plans across most U.S. counties. This page covers how UnitedHealthcare’s 2027 Medicare Advantage plans work, what plan types are typically available, and how to compare them against other carriers before you enroll.

For the full picture on how Medicare Advantage works overall — plan types, star ratings, enrollment periods, and costs — see our complete 2027 Medicare Advantage guide. If you’d rather see real plan options now, compare 2027 Medicare Advantage plans in your area by ZIP code.

What's Confirmed for UnitedHealthcare in 2027 - and What Isn't

Confirmed: The federal rules every UnitedHealthcare plan must follow. CMS finalized the CY 2027 Medicare Advantage and Part D rule on April 2, 2026 — the $2,400 prescription out-of-pocket cap, the $700 standard Part D deductible, eleven star-rating measures removed, and new supplemental benefit disclosure requirements.

Not confirmed: UnitedHealthcare’s specific 2027 premiums, which counties each plan is offered in, the dental, vision, hearing, and OTC allowances on any given plan, and its 2027 star ratings. All released October 15, 2026.

Any page quoting a specific UnitedHealthcare 2027 premium or benefit right now is guessing. Confirm every benefit you’re counting on in that plan’s official Summary of Benefits before you enroll.

About UnitedHealthcare Medicare Advantage Plans

UnitedHealthcare is a private insurance carrier that contracts with Medicare to offer Medicare Advantage (Part C) plans.

As one of the largest carriers in the Medicare Advantage market, UnitedHealthcare typically offers a wide range of plan types and service areas, though specific plan availability, benefits, and pricing vary by county and change from year to year.

Like other Medicare Advantage carriers, such as Blue Cross Blue Shield Medicare Advantage, UnitedHealthcare must cover everything Original Medicare Part A and Part B cover, and often adds supplemental benefits on top — though the specific extras available depend on the plan and your ZIP code.

UnitedHealthcare by the Numbers

Unitedhealthcare market penetration and numbers

The most recent finalized data — 2026 enrollment figures and 2026 CMS star ratings:

Measure UnitedHealthcare What it means for you
Share of MA enrollment ~26% Largest carrier — plans available in most counties nationwide
Members in 4+ star plans 78% Strong but not top of class — Aetna was above 81%, Kaiser 100% of contracts
Combined with Humana ~46% of market Two carriers cover nearly half of all enrollees
Plan types offered HMO, PPO, SNP Availability varies county by county

Scale is a genuine advantage for provider access — a deeper network lowers the odds that a specialist you need next year falls outside it, and out-of-network care is where unplanned costs come from. It is not a guarantee: UnitedHealthcare sells narrow HMO products in some markets. Check your own doctors against the exact plan number, not the carrier name.

What UnitedHealthcare May Offer for 2027

UnitedHealthcare’s specific 2027 plan details — premiums, star ratings, and supplemental benefits — are finalized by CMS and released publicly during the Annual Enrollment Period. Based on how the carrier has historically structured its Medicare Advantage plans, 2027 offerings may include:

HMO and PPO plan options, depending on your county.

Prescription drug coverage bundled into many plans.

Dental, vision, and hearing benefits on select plans.

Over-the-counter (OTC) allowances and fitness program access on select plans.

Not all plans offer all benefits, and availability depends on your plan and service area. Confirm specific 2027 Medicare Advantage plan benefits directly with a licensed agent or through the plan’s official Summary of Benefits before enrolling.

The 2027 Part D Changes That Affect Every UnitedHealthcare Plan

Medicare Part D cap for 2027

Most UnitedHealthcare Medicare Advantage plans bundle prescription drug coverage, which means these federal parameters apply regardless of which plan you choose:

Part D Parameter 2026 2027 Change
Annual out-of-pocket cap $2,100 $2,400 +$300
Standard deductible $615 $700 +$85
Coverage gap (“donut hole”) Eliminated Eliminated No change
Catastrophic phase cost sharing $0 $0 No change

Once you’ve spent $2,400 out of pocket on covered prescriptions in 2027, you pay nothing more for formulary drugs the rest of the calendar year. Check every medication against the specific plan’s 2027 drug list, including tier — that determines how fast you reach the cap.

UnitedHealthcare Plan Types Available

UnitedHealthcare typically offers Medicare Advantage plans across the main plan type categories, though which types are available depends on your county. For a full breakdown of how each plan type works — network rules, referral requirements, and cost structure — see our 2027 Medicare Advantage plan types guide.

HMO Plans

Unitedhealthcare Medicare advantage hmo for 2027

UnitedHealthcare Medicare Advantage HMO plans in 2027 generally require you to use a network of doctors and hospitals, with a primary care physician coordinating your care. These plans often carry lower premiums and copays in exchange for the network requirement.

PPO Plans

UnitedHealthcare PPO plans offer more flexibility to see out-of-network providers at a higher cost, without needing referrals for specialists. This option tends to suit people who travel or want more provider choice.

UnitedHealthcare Network & Provider Access

UnitedHealthcare maintains one of the larger provider networks among Medicare Advantage carriers, but actual network size and specific in-network doctors and hospitals vary significantly by county. Before enrolling, confirm that your current doctors, specialists, and preferred hospital participate in the specific UnitedHealthcare plan you’re considering — network participation can change year to year, including for 2027.

What Might UnitedHealthcare 2027 Plans Cost?

What Medicare advantage plans in 2027 cost
  • Monthly premium: UnitedHealthcare offers $0-premium plans in many areas, but availability depends on your ZIP code — you’ll still pay your Medicare Part B premium regardless
  • Deductibles & copays: vary by specific plan; always confirm against the plan’s official Summary of Benefits
  • Out-of-pocket maximum: like all Medicare Advantage plans, UnitedHealthcare plans cap your annual out-of-pocket spending
  • Extra benefits: dental, vision, hearing, and OTC allowances vary by specific plan and ZIP code

What Star Ratings Say About UnitedHealthcare Plans

UnitedHealthcare Medicare Advantage star ratings 2027

In 2026, 78% of UnitedHealthcare’s Medicare Advantage members were in plans rated 4 stars or higher. Solid, and below Aetna’s 81%+ and Kaiser’s 100% of contracts.

Ratings matter beyond quality: they drive the bonus payments that fund supplemental benefits and $0 premiums. A plan whose rating slips has less to spend on members the following year.

The industry average fell for 2026 — 3.65 stars, down from 3.92. Ratings moved down across the board, not just at one carrier.

Ratings are assigned at the contract level, so two UnitedHealthcare plans under one contract share a rating even if their benefits differ.

The 2027 measure set changed. CMS removed 11 measures and discontinued one reward, so a 2027 rating isn’t a clean like-for-like against 2025.

Is UnitedHealthcare Medicare Advantage Right for You?

UnitedHealthcare tends to be worth considering if you:

  • Want a carrier with broad provider network reach in most areas of the country
  • Are interested in plans that may bundle dental, vision, and hearing benefits
  • Want the option to choose between HMO and PPO structures depending on your area

As with any carrier, the right choice depends on your specific doctors, prescriptions, and budget — not the carrier name alone. Comparing UnitedHealthcare against other carriers side by side is the best way to confirm fit for your situation.

UnitedHealthcare Medicare Advantage 2027 — Frequently Asked Questions

Does UnitedHealthcare offer $0 premium Medicare Advantage plans for 2027?

UnitedHealthcare offers $0-premium plans in many areas, though availability depends on your specific ZIP code and county. You’ll still need to pay your Medicare Part B premium regardless of which plan you choose.

Does UnitedHealthcare Medicare Advantage include dental and vision coverage?

Many UnitedHealthcare Medicare Advantage plans may include dental, vision, and hearing benefits, but not all plans offer all benefits. Confirm specific coverage for any plan you’re considering before enrolling.

Can I keep my current doctor with a UnitedHealthcare Medicare Advantage plan?

It depends on the specific plan and whether your doctor participates in that plan’s network. HMO plans generally require in-network care, while PPO plans allow out-of-network visits at a higher cost. Always confirm your doctors are in-network before enrolling.

How does UnitedHealthcare compare to other Medicare Advantage carriers?

UnitedHealthcare is one of the largest Medicare Advantage carriers, but the “best” carrier depends on your specific doctors, prescriptions, and budget rather than carrier size alone. Comparing plans by ZIP code is the most reliable way to see which carrier fits your situation.

When can I enroll in a UnitedHealthcare 2027 Medicare Advantage plan?

You can enroll during the Annual Enrollment Period, October 15 – December 7, 2026, for coverage effective January 1, 2027. If you’re new to Medicare, you may also be able to enroll during your Initial Enrollment Period.

  How big is UnitedHealthcare’s Medicare Advantage market share?

UnitedHealth Group covered roughly 26% of all Medicare Advantage enrollees in 2026, the largest share of any carrier. Together with Humana at roughly 20%, the two companies accounted for about 46% of the entire Medicare Advantage market. Scale means broad county availability, but it doesn’t guarantee a strong network in your specific area.

  What are UnitedHealthcare’s Medicare Advantage star ratings?

For 2026, 78% of UnitedHealthcare’s Medicare Advantage members were enrolled in plans rated 4 stars or higher. For context, Aetna had more than 81% of members in 4-star-or-better plans and Kaiser Permanente had 100% of its contracts at 4+ stars. Ratings are assigned at the contract level and recalculated annually, so 2027 figures publish in the fall.

  What is the Medicare Part D out-of-pocket cap for 2027?

The 2027 annual out-of-pocket cap for prescription drugs is $2,400, up from $2,100 in 2026, and the standard Part D deductible is $700, up from $615. These federal parameters apply to every Medicare Advantage plan with drug coverage, including UnitedHealthcare’s. Once you reach the cap you pay nothing more for covered formulary drugs that calendar year.

  What plan types does UnitedHealthcare offer for 2027?

UnitedHealthcare typically offers HMO, PPO and Special Needs Plans, though which types are available depends on your county. HMO plans require in-network providers and usually a referral for specialists, with lower typical costs. PPO plans allow out-of-network care at higher cost without referrals. SNPs serve people with qualifying circumstances such as dual Medicare-Medicaid eligibility or certain chronic conditions.

  Do I still pay the Part B premium with a UnitedHealthcare plan?

Yes. Medicare Advantage changes how your Part A and Part B benefits are delivered, but you remain enrolled in Medicare and keep paying the Part B premium. Some UnitedHealthcare plans in select counties offer a Part B giveback that reduces this amount, but that’s a specific plan feature and not a general rule.

  What is the out-of-pocket maximum on a UnitedHealthcare plan?

Every UnitedHealthcare Medicare Advantage plan caps your annual in-network medical spending — a structural advantage over Original Medicare, which has no cap. The specific amount varies substantially between plans, sometimes by several thousand dollars in the same county, which makes it the single most useful number when comparing two plans. It’s separate from the $2,400 prescription drug cap.
