UnitedHealthcare Medicare Advantage Cuts for 2026 & 2027

UnitedHealthcare has been shrinking its Medicare Advantage business since 2025, and that story is now extending into 2027.

It started with UnitedHealthcare announcing plans to exit Medicare Advantage products that served more than 600,000 members going into 2026.

Since then, the company's own enrollment projections have grown well past that number, and a new report shows it's already considering additional county exits for 2027.

Here's the full timeline, what it actually means if you have a UnitedHealthcare Medicare Advantage plan, and what to watch for this fall.

UnitedHealthcare Medicare Advantage Reduction Timeline

UnitedHealthcare's reported Medicare Advantage membership, per its own earnings disclosures.

Is It 600,000 or 1.1 Million? Here's the Difference

These are two different numbers measuring two different things, and mixing them up is where most of the confusion comes from.

The 600,000 figure is the number of members in the specific Medicare Advantage products UnitedHealthcare announced it would exit for 2026 — a targeted, company-announced list of plans.

The 1.1 million figure is UnitedHealthcare's own projection for how much its total Medicare Advantage enrollment will shrink during 2026, across the entire book of business.

That's a much broader number. It includes the members from those targeted plan exits.

But it also reflects other enrollment gains and losses across UnitedHealthcare's Medicare Advantage business, including members who chose coverage outside UnitedHealthcare.

In other words: the 600,000 figure relates to targeted product exits.

The 1.1 million figure reflects UnitedHealthcare's projected overall enrollment contraction, which includes those exits plus other enrollment gains and losses across its Medicare Advantage business.

Neither number means 600,000 or 1.1 million people lost Medicare coverage entirely. Most had other Medicare Advantage options, a different UnitedHealthcare plan, or Original Medicare available to them.

Framed this way, the original 600,000-member headline was really the opening chapter of a larger, ongoing contraction — not the whole story.

What the Preliminary 2027 County Exits Look Like

UnitedHealth Group told Modern Healthcare that the 34-county list is preliminary and still subject to change.

Carriers can't confirm 2027 plan details to members until October 1.

Is my county affected? The preliminary list is broken out by state below.

Remember that UnitedHealthcare has described these possible exits as not final — official 2027 plan availability in your specific county should be verified once Medicare's 2027 plan information becomes available on October 1.

More than 20,000 current UnitedHealthcare Medicare Advantage members are in the plans on this preliminary list. That's about 0.3% of the company's roughly 7.5 million Medicare Advantage members nationwide.

Many of the counties are rural, and roughly two-thirds of the affected plans are reportedly PPOs.

Most members in the affected plans are expected to have another UnitedHealthcare Medicare Advantage option available.

That's not the same as an equivalent option — a replacement plan can have a different network, formulary, copays, and maximum out-of-pocket limit, even under the same company name.

We'd recommend comparing the actual plan details rather than assuming continuity.

UnitedHealthcare May Also Reduce Supplemental Benefits in 2027

County exits aren't the only change to watch.

UnitedHealthcare's CEO has also said the company plans to reduce supplemental benefits as part of its broader effort to improve Medicare Advantage profitability.

A plan doesn't have to be discontinued for a member to feel a real change. A plan renewing into 2027 could still see its:

• Dental, vision, or hearing benefits change
• Other supplemental extras reduced
• Copays or cost-sharing adjusted
• Provider network narrowed
• Drug formulary or pharmacy network changed

Seeing that your plan renewed isn't the end of the review — how it renewed matters just as much.

Our guide on why Medicare Advantage plans change every year goes deeper into why this happens even to plans that aren't discontinued.

Why Is UnitedHealthcare Doing This?

UnitedHealthcare has cited higher medical utilization and rising healthcare costs as major pressures on its Medicare Advantage business.

At the same time, insurers have been adapting to changes in Medicare Advantage payment methodology, risk adjustment, Star Ratings, and other program rules.

For 2027, CMS finalized policies it estimates will increase average Medicare Advantage payments by 2.48%, or more than $13 billion — a 4.98% increase when accounting for the agency's estimated risk-score trend.

Even with higher overall payments, individual insurers still have to decide whether particular plans, benefits, and service areas meet their own financial targets.

This isn't unique to UnitedHealthcare. Humana has made similar reductions heading into 2026 and 2027, and Aetna made cuts of its own.

This kind of contraction has become a recurring pattern across the Medicare Advantage market in recent years. See our breakdown of the 2026 Medicare Advantage enrollment winners and losers for the wider picture.

What to Watch This Fall

September 2026: Read Your Annual Notice of Change

Plans send members an Annual Notice of Change (ANOC) explaining what's different for the following year.

Don't assume 2027 coverage is identical just because the UnitedHealthcare name is still on the card.

When your ANOC arrives, compare these against what you have today:

• Monthly premium
• Primary and specialist copays
• Hospital and outpatient costs
• Maximum out-of-pocket limit
• Drug formulary
• Doctors and hospitals in network
• Dental, vision, hearing, and other extras

Compare your 2027 plan to the coverage you have today first — not to another plan.

That's the comparison that actually tells you what's changing for you.

If you receive a nonrenewal or termination notice, keep it — it may matter for the guaranteed issue rights covered below.

October 1, 2026: Official 2027 Plan Details Become Available

UnitedHealth Group told Modern Healthcare that carriers can't announce 2027 plans to members until October 1, which is also when CMS typically updates Medicare Plan Finder.

That's when the preliminary 34-county list either becomes final, changes, or partially reverses.

October 15 – December 7, 2026: Annual Enrollment Period

This is when you can compare and switch plans for 2027.

If your plan changed, don't decide off a headline — compare your actual doctors, prescriptions, costs, and network against your other options.

If Your Plan Is Discontinued: Guaranteed Issue Rights

If UnitedHealthcare discontinues your Medicare Advantage plan or leaves your service area, you may qualify for Medicare enrollment protections — and potentially Medigap guaranteed issue rights.

Guaranteed issue can let you enroll in certain Medicare Supplement plans without medical underwriting, regardless of pre-existing conditions.

That's normally not the case — applying for Medigap outside your initial enrollment window can otherwise mean a health-history review, and possibly a higher rate or a decline.

Timing matters. For certain guaranteed-issue situations, Medicare advises applying no later than 63 days after your previous coverage ends, and keeping your plan termination notice as proof.

State laws can also provide additional Medigap protections beyond the federal rules.

Rules and timing depend on your specific circumstances, so it's worth confirming exactly what applies to you before choosing your next plan.

Bottom Line

UnitedHealthcare's Medicare Advantage story has grown from a single 600,000-member headline into a multi-year contraction.

That contraction includes an expected 1.1 million member decline in 2026, and a preliminary look at further county exits and benefit reductions for 2027.

If you have a UnitedHealthcare Medicare Advantage plan, don't react to the headline alone.

Read your ANOC, check your doctors and prescriptions, and compare your real options during Annual Enrollment.

And if your plan is discontinued, it's worth finding out whether that opens a guaranteed issue window — it may create an important opportunity to consider Medigap without medical underwriting.
