UnitedHealthcare Plans May Include
Hospital and medical coverage, the same as Original Medicare Part A and B
Part D prescription drug coverage on most plans
Routine dental, vision and hearing benefits
Fitness programs and over-the-counter allowances
Telehealth visits and care coordination programs

Not all plans offer all benefits. Benefits vary by plan and county and can change for 2027. Check each plan’s Evidence of Coverage before you enroll.
Watch for: if your plan is ending, you will get a non-renewal letter. Your coverage continues through December 31, 2026. If you do nothing, you return to Original Medicare without drug coverage.
Guaranteed issue: if your Medicare Advantage plan leaves your area, you generally can buy certain Medicare Supplement plans without health questions, until 63 days after your coverage ends.

Medicare Advantage, also called Part C, is a way to get your Medicare benefits through a private insurance company approved by Medicare. The plan covers everything Original Medicare Part A and Part B cover, except hospice care, which Original Medicare still pays. Most plans also include Part D drug coverage, and many may add extras such as routine dental, vision and hearing benefits.
In exchange, UnitedHealthcare plans generally use networks of doctors and hospitals, and may require referrals or prior authorization for some services. Every Medicare Advantage plan has a yearly out-of-pocket maximum for covered medical care, which Original Medicare does not have. You keep paying your Part B premium, plus your plan’s premium if it has 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 |
Advantages
Often a low or $0 premium
A yearly out-of-pocket maximum
Drug coverage usually included
Many plans may include dental, vision and hearing benefits
One card and one plan
Tradeoffs
Networks; HMOs require in-network care except emergencies
Prior authorization and referrals are common
Copays add up if you use a lot of care
Plans and networks can change every year
Switching to Medigap later may require health questions
Most UnitedHealthcare Medicare Advantage plans include Part D drug coverage. Each plan has its own formulary, drug tiers and pharmacy network, and plans commonly charge less at preferred pharmacies and through mail order. For 2027, any plan’s Part D deductible can be up to $700, and the out-of-pocket cap on covered drugs is $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 |
Tier structures vary by plan. Check each plan’s formulary.
Sometimes a drug you take is not on a plan’s 2027 formulary, or it carries a rule like prior authorization. You still have options:
If Your Drug Is Not Covered
Ask for a transition fill. In the first 90 days of a new plan year or a new plan, plans generally must give you a temporary supply of a drug you were already taking, so you have time to switch or request an exception.
Ask your doctor about alternatives. A covered drug in the same class may work as well and cost less.
Request a formulary or tiering exception. Your doctor submits a statement explaining why you need the drug or a lower copay. Plans must decide within set time limits.
Appeal a denial. If the plan says no, you can appeal, and there are several levels of review.
If your UnitedHealthcare plan will not be offered in your county for 2027, you should have received a non-renewal notice in early October. Your coverage does not stop right away: it continues through December 31, 2026, so you have time to choose.
If Your Plan Is Ending
Read the non-renewal letter. It confirms your plan is ending and explains your options.
List your doctors and drugs. You will need them to compare replacement plans.
Compare plans for 2027. Check networks, drug coverage and the out-of-pocket maximum, not just the premium.
Choose by December 31 for no gap. Enrolling during Annual Enrollment by December 7 gives you coverage on January 1, 2027.
Use your Special Enrollment Period if needed. People whose plans end generally can still make a choice through the end of February 2027.
If you do nothing: you return to Original Medicare on January 1, 2027, without drug coverage unless you choose a Part D plan. Going without drug coverage can lead to a late enrollment penalty.
Medigap rights: when your Medicare Advantage plan leaves your area, you generally have a guaranteed issue right to buy certain Medicare Supplement plans without health questions, up to 63 days after your coverage ends.
How to Compare
Read your Annual Notice of Change. It lists every change to your current plan for 2027.
Check your doctors and hospitals. Confirm each provider is in the 2027 network, not just the 2026 one.
Check your prescriptions. Confirm each drug, its tier and any prior authorization or step therapy rules.
Compare total yearly cost. Add the premium, typical copays and drug costs, and look at the out-of-pocket maximum.
Check star ratings. Medicare rates plans from 1 to 5 stars on quality and service.
Enroll by December 7. Your new coverage starts January 1, 2027.
| Enrollment Period | Dates | What You Can Do |
|---|---|---|
| Annual Enrollment Period | October 15 to December 7, 2026 | Join, switch or drop a Medicare Advantage or Part D plan for January 1, 2027 |
| Medicare Advantage Open Enrollment | January 1 to March 31, 2027 | If you are in Medicare Advantage, switch to another plan or return to Original Medicare once |
| Initial Enrollment Period | 7 months around your 65th birthday month | Sign up for Medicare and choose your first plan |
| Special Enrollment Periods | Varies | Change plans after events like moving, losing other coverage or your plan leaving your area |
Most people make changes during Annual Enrollment. If you are happy with your current plan, you do not have to do anything; it renews automatically. Still, read your Annual Notice of Change, because premiums, copays, networks and drug lists can all change on January 1.
Special Needs Plans (SNPs) are Medicare Advantage plans built for specific groups. Benefits, networks and drug lists are designed around the members they serve, and many include care coordinators. For 2027, Special Needs Plans are one of the few areas where large insurers are adding plans, even as they cut PPOs.
| Type | Who Qualifies | What Is Different |
|---|---|---|
| Dual Special Needs Plan (D-SNP) | People with both Medicare and Medicaid | Coordinates both programs; often very low costs and added benefits |
| Chronic Condition SNP (C-SNP) | People with qualifying conditions such as diabetes, heart failure or chronic lung disease | Doctors, drugs and programs built around the condition |
| Institutional SNP (I-SNP) | People living in a nursing home or who need that level of care at home | Care delivered where the member lives |
If you turn 65 in 2027, your Initial Enrollment Period lasts seven months: the three months before your birthday month, your birthday month and the three months after. Signing up during the first three months means your coverage starts on the first day of your birthday month.
Turning 65 Checklist
Sign up for Part A and Part B, unless you have qualifying employer coverage and choose to delay Part B
Decide between Medicare Advantage and Original Medicare with Medigap
Join a drug plan, or a Medicare Advantage plan with drugs, to avoid a Part D late penalty
If you choose Medigap, buy during your six-month Medigap Open Enrollment Period
Medicare rates every Medicare Advantage and Part D plan from 1 to 5 stars each fall, based on things like preventive care, how well the plan manages chronic conditions, member complaints, customer service and drug pricing accuracy. The ratings are shown in Medicare Plan Finder.
Using Star Ratings
A rating of 4 stars or higher is generally a good sign of quality and service
Five-star plans have a special enrollment period, so you can switch into one once during the year
New plans may not have a rating yet, which is not a bad sign by itself
Ratings measure the plan overall, not how well it covers your specific doctors and drugs
| 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; little or nothing on Plan G after the Part B deductible |
| 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 after your Medigap Open Enrollment Period |
If your income and savings are limited, two programs can cut your Medicare costs sharply:
Medicare Savings Programs
Run by your state Medicaid office
Can pay your Part B premium, and sometimes 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
People in a Medicare Savings Program qualify automatically
Those who are eligible for Medicare along with full Medicaid might also have the option of enrolling in a Dual Special Needs Plan. Learn more about help for low-income Part D beneficiaries.
You do not have to compare plans alone, and you should not have to pay for help. These are the free options:

Before any call, have your Medicare card, your list of drugs and doses, your doctors and your preferred pharmacies ready. It turns a long conversation into a short one.
The Bottom Line
Choose the UHC path that fits your doctors and budget, and compare during Annual Enrollment.
UnitedHealthcare offers Medicare Advantage plans, Medicare Supplement (Medigap) plans and standalone Part D prescription drug plans. Which specific plans you can buy depends on your county and state, so check availability by ZIP code before comparing benefits and costs.
You can join or switch to a UnitedHealthcare Medicare Advantage plan from October 15 to December 7, 2026, with coverage starting January 1, 2027. If you are already in a Medicare Advantage plan, you also get one change between January 1 and March 31, 2027.
A non-renewal is not an emergency, because your current plan stays active through December 31, 2026. The notice qualifies you for a Special Enrollment Period, and you generally have a guaranteed issue right to buy certain Medigap plans, typically within 63 days after the old coverage ends.
UnitedHealthcare will offer 852 Medicare Advantage plans for 2027, up from 846, while exiting about 140 counties and leaving Wyoming entirely. It is also cutting 34 PPO plans and adding 40 Special Needs Plans, so read your Annual Notice of Change closely.
It might be, since UnitedHealthcare is exiting about 140 counties and all of Wyoming for 2027. The surest way to know is your Annual Notice of Change or a non-renewal letter, and you can also check plan availability for your ZIP code.
Yes. UnitedHealthcare is adding 40 Special Needs Plans for 2027, which are designed for people with certain chronic conditions, people with both Medicare and Medicaid, or those living in an institution. Eligibility rules and availability vary by plan and county, so confirm before enrolling.
It depends on your priorities. Medicare Advantage often has lower premiums but uses networks and copays, while Medigap with Original Medicare costs more monthly but lets you see any provider that accepts Medicare. Medigap cannot be combined with Medicare Advantage, and switching to Medigap later may involve health questions.
Some may. UnitedHealthcare plans may include dental, vision, hearing or over-the-counter benefits, but not all plans offer all benefits, and the details can change each year. Check the 2027 Summary of Benefits for the specific plan in your county.
Yes, UnitedHealthcare offers standalone Part D plans, though availability and premiums vary by region. For 2027 a Part D deductible can be up to $700, out-of-pocket drug costs are capped at $2,400, and low-premium options are widely available from various insurers.
