Health insurance decisions can change considerably as adults approach retirement and Medicare eligibility.

Before Medicare eligibility, an older adult may receive coverage through an employer, a spouse's employer, an individual health plan or another qualifying source. Once eligible for Medicare, the choices can expand to include Original Medicare, Medicare Advantage, Medicare Supplement insurance and Medicare prescription drug coverage.

Major companies and organizations serving the Medicare market include UnitedHealthcare, Humana, Aetna, Blue Cross Blue Shield and WellCare.

These companies do not offer identical coverage in every location. Premiums, provider networks, deductibles, copayments, prescription formularies and additional benefits can vary by individual plan and service area.

Understanding how the major types of coverage work make it easier to compare plans on more than the monthly premium alone.

Health Insurance Options for Seniors in 2026

Senior health insurance is not one specific insurance product.

Depending on age and eligibility, options can include:

Employer or retiree health coverage — Coverage through current or former employment.

Individual health insurance — Private coverage that may be relevant before Medicare eligibility.

Original Medicare — Medicare Part A and Part B administered by the federal government.

Medicare Advantage — Private Medicare plans that provide Part A and Part B benefits and often incorporate additional benefits.

Medicare Supplement insurance — Private insurance designed to help with certain out-of-pocket expenses under Original Medicare.

Medicare Part D — Prescription drug coverage available through private Medicare-approved plans.

The appropriate combination depends on Medicare eligibility, healthcare needs, prescription drugs, preferred providers, finances and available plans.

Medicare Eligibility for Seniors

Medicare is generally available beginning at age 65.

Some people can qualify before 65 because of disability or certain medical circumstances.

For adults approaching Medicare eligibility, timing is important because enrollment periods can affect when coverage starts and, in some situations, whether late-enrollment penalties apply.

Someone who continues working after 65 or receives health insurance through a spouse's current employer should determine how that coverage coordinates with Medicare before changing insurance.

Original Medicare: Part A and Part B

Original Medicare consists primarily of Part A and Part B.

Medicare Part A

Part A generally helps cover qualifying:

Inpatient hospital care
Skilled nursing facility care
Hospice
Certain home healthcare

Approximately 99% of Medicare beneficiaries do not pay a monthly Part A premium because they or a spouse accumulated sufficient Medicare-covered employment.

Medicare Part B

Part B generally helps cover:

Physician services
Outpatient hospital services
Certain home health services
Durable medical equipment
Other qualifying medical services

Part B generally requires a monthly premium.

2026 Medicare Part A and Part B Costs

CMS has published the official Medicare Part A and Part B amounts for 2026.

Medicare Cost	2026 Amount
Standard Part B premium	$202.90/month
Part B annual deductible	$283
Part A inpatient hospital deductible	$1,736 per benefit period
Part A hospital coinsurance, days 61–90	$434/day
Part A lifetime reserve day coinsurance	$868/day
Skilled nursing facility coinsurance, days 21–100	$217/day
Reduced Part A premium for qualifying individuals	$311/month
Full Part A premium when applicable	$565/month

The standard Part B premium increased to $202.90 per month in 2026, while the annual Part B deductible is $283. Approximately 99% of beneficiaries continue to receive premium-free Part A.

Higher-income beneficiaries can pay an income-related adjustment in addition to the standard Part B premium.

Medicare Advantage Plans for Seniors

Medicare Advantage, also called Medicare Part C, is offered through private insurance companies participating in Medicare.

A Medicare Advantage plan provides Medicare Part A and Part B benefits through the private plan rather than receiving those benefits directly through Original Medicare.

Many Medicare Advantage plans also include additional benefits or services.

Depending on the individual plan, these can include:

Prescription drug coverage
Routine dental
Routine vision
Hearing benefits
Fitness benefits
Transportation
Other supplemental benefits

Benefits vary significantly by plan.

Medicare Advantage plans also have annual limits on qualifying out-of-pocket medical spending, unlike Original Medicare by itself.

Medicare Advantage HMO Plans

Health Maintenance Organization plans generally emphasize a defined provider network.

An HMO may require members to receive non-emergency care from network doctors and hospitals.

Some plans also require a primary care provider or referrals for certain specialist services.

HMO plans can appeal to people comfortable receiving care within a defined network.

Before enrollment, seniors can verify whether their physicians, hospitals and specialists participate in the specific plan.

Medicare Advantage PPO Plans

Preferred Provider Organization plans generally provide more flexibility to use providers outside the plan network, although out-of-network care can cost more.

Aetna's current 2026 PPO information, for example, says members can visit providers inside or outside the network when those providers accept Medicare and the plan's terms.

For seniors who travel frequently or want broader provider flexibility, PPO availability can be an important comparison factor.

UnitedHealthcare Medicare Plans

UnitedHealthcare is one of the largest companies serving Medicare beneficiaries.

Its Medicare offerings can include Medicare Advantage, Medicare Supplement and other Medicare-related coverage depending on location and eligibility.

UnitedHealthcare also insures AARP-branded Medicare Supplement plans.

When evaluating a UnitedHealthcare Medicare Advantage plan, useful factors to compare include:

Monthly premium
Medical deductible
Primary care copayment
Specialist copayment
Hospital costs
Prescription coverage
Provider network
Maximum out-of-pocket amount
Dental benefits
Vision benefits
Hearing benefits

The exact benefits should be checked for the individual plan rather than assumed from the UnitedHealthcare brand alone.

Humana Medicare Plans

Humana remains another major Medicare company in 2026.

Humana reports that its 2026 Medicare Advantage offerings cover 46 states plus Washington, D.C. and approximately 85% of U.S. counties.

Humana Medicare Advantage options can include different plan structures depending on the market.

The company also says its 2026 Medicare Advantage plans include routine dental, vision and hearing benefits, although exact benefits and cost sharing depend on the plan.

Humana continues to offer three standalone Medicare prescription drug plan options in 2026.

For someone considering Humana, comparing the local provider network and prescription formulary can be as important as comparing the premium.

Aetna Medicare Plans

Aetna offers several Medicare Advantage structures in 2026.

Depending on availability, these include:

HMO plans

Members generally use network providers except for emergencies, with specific referral and PCP rules varying by plan.

HMO-POS plans

These plans combine an HMO-style network with certain additional flexibility.

PPO plans

Members can use in-network or qualifying out-of-network providers, although out-of-network care can cost more.

D-SNPs

Dual Eligible Special Needs Plans are designed for qualifying people eligible for both Medicare and Medicaid.

Aetna currently advertises some Medicare Advantage options with monthly plan premiums as low as $0, but premiums, deductibles and benefits vary by plan and location.

A $0 Medicare Advantage plan premium does not mean healthcare is free. Members generally must continue paying any applicable Medicare Part B premium and can have copayments, coinsurance, deductibles and other out-of-pocket expenses.

Blue Cross Blue Shield Medicare Plans

Blue Cross Blue Shield represents independent Blue Cross and Blue Shield companies serving different geographic markets.

Available Medicare coverage can include:

Medicare Advantage
Medicare Supplement
Prescription drug coverage

BCBS explains that Medicare Advantage plans provide Part A and Part B services while potentially incorporating additional services such as wellness, hearing and vision benefits.

Plan availability is determined by the applicable local Blue Cross and Blue Shield company.

This makes the specific BCBS company and plan more important than simply comparing the national brand name.

Wellcare Medicare Plans

Wellcare provides Medicare-related insurance products, including Medicare Advantage and prescription drug coverage in participating markets.

As with other Medicare insurers, available plans can vary by location.

When considering Wellcare, seniors can compare:

Monthly plan premium
Prescription coverage
Pharmacy network
Medical network
Copayments
Deductibles
Out-of-pocket maximum
Additional benefits
Prior authorization requirements

Prescription coverage deserves particular attention for someone taking several ongoing medications.

UnitedHealthcare vs. Humana vs. Aetna vs. BCBS vs. Wellcare

Comparing major companies is useful, but the individual plan ultimately matters more than the brand alone.

Provider	Coverage to Investigate	Important Comparison Area
UnitedHealthcare	Medicare Advantage, Medicare Supplement	Provider network and plan costs
Humana	Medicare Advantage, Part D and other Medicare coverage	Benefits, prescriptions and network
Aetna	HMO, HMO-POS, PPO, D-SNP	Network structure and out-of-network flexibility
Blue Cross Blue Shield	Medicare Advantage, Medigap, Part D	Local BCBS company and network
Wellcare	Medicare Advantage and prescription coverage	Drug formulary and pharmacy network

A company that works particularly well for one Medicare beneficiary may not be the strongest choice for another.

Medicare Advantage vs. Original Medicare

One of the largest decisions is whether to receive Medicare benefits through Original Medicare or a Medicare Advantage plan.

Feature	Original Medicare	Medicare Advantage
Part A hospital coverage	Yes	Yes
Part B medical coverage	Yes	Yes
Private insurer manages core benefits	No	Yes
Provider network	Broad Medicare participation	Usually plan-specific
Prescription coverage	Separate Part D generally needed	Often included
Annual medical out-of-pocket maximum	No	Yes
Additional dental/vision/hearing	Generally not routine coverage	May be included
Medigap compatibility	Yes	No

The best structure depends on individual preferences.

Some people prioritize broader provider access under Original Medicare.

Others prefer Medicare Advantage because medical and prescription coverage may be combined and additional benefits may be available.

Medicare Supplement Insurance

Medicare Supplement insurance, commonly called Medigap, works alongside Original Medicare.

It is designed to help pay certain deductibles, coinsurance and other cost-sharing amounts that Original Medicare does not fully cover.

Medigap is different from Medicare Advantage.

With Medigap, the beneficiary generally remains enrolled in Original Medicare and purchases a standardized supplemental policy from a private insurer.

A person cannot use a Medigap policy to supplement a Medicare Advantage plan.

Medicare Supplement Plan G

Plan G is one of the Medicare Supplement options frequently considered by people newly eligible for Medicare.

For Medicare beneficiaries first eligible after January 1, 2020, Medigap plans cannot cover the Medicare Part B deductible.

With Plan G, a beneficiary generally pays the applicable Part B deductible before Plan G's relevant Part B cost-sharing coverage begins.

In 2026, that Part B deductible is $283.

Medigap premiums vary by insurance company, location, age-rating method and other permitted factors.

Medicare Prescription Drug Coverage

Prescription drug coverage is another major consideration.

Someone using Original Medicare can purchase a standalone Medicare Part D plan.

Many Medicare Advantage plans incorporate Part D prescription coverage directly.

Comparing drug coverage involves more than looking at the monthly premium.

Important considerations include:

Whether medications are on the formulary
Drug tier
Deductible
Copayment or coinsurance
Preferred pharmacies
Mail-order availability
Prior authorization
Quantity limits
Step therapy requirements

A plan with a lower premium can potentially cost more overall if a person's medications receive less favorable coverage.

Dental, Vision and Hearing Benefits

Routine dental, vision and hearing services are not generally covered by Original Medicare in the same way as standard hospital and physician services.

Many Medicare Advantage plans therefore use these supplemental benefits as important plan features.

Coverage can include items such as:

Dental: Exams, cleanings, X-rays and certain additional services depending on the plan.

Vision: Routine eye exams and allowances or benefits for eyewear.

Hearing: Hearing exams and hearing-aid benefits under applicable plans.

The dollar limits, provider networks and covered services vary.

Consumers should review the actual evidence of coverage rather than assuming that “dental included” means unlimited dental treatment.

$0-Premium Medicare Advantage Plans

Some Medicare Advantage plans advertise a $0 monthly plan premium.

This can reduce the additional premium paid directly to the private plan.

However, $0 premium does not mean $0 healthcare cost.

Members generally continue paying the applicable Medicare Part B premium and may also encounter:

Deductibles
Doctor copays
Specialist copays
Hospital cost sharing
Prescription costs
Out-of-network costs
Other plan-specific expenses

In 2026, the standard Medicare Part B premium is $202.90 per month.

For that reason, comparing total expected healthcare spending is more useful than comparing plan premiums alone.

Medicare Out-of-Pocket Costs

A Medicare plan can expose members to several different categories of expense.

These can include:

Premium — Regular amount paid for coverage.

Deductible — Amount the member pays before applicable coverage begins.

Copayment — Fixed amount for a covered service.

Coinsurance — Percentage of a covered cost.

Maximum out-of-pocket amount — Annual limit on qualifying medical expenses under Medicare Advantage.

Prescription drug expenses can follow a separate cost structure.

When comparing plans, seniors can consider both routine expenses and what the policy could cost during a year involving substantial medical care.

Provider Networks

Provider networks can be one of the most important differences between Medicare Advantage plans.

Before changing plans, consumers can check whether their preferred:

Primary care physician
Specialists
Hospital
Clinic
Pharmacy

participate in the plan.

Provider participation can change, so current network information should be verified rather than relying solely on previous-year coverage.

Prescription Formularies

A formulary is the plan's list of covered prescription drugs.

Two Medicare plans from different companies can treat the same medication very differently.

One may place a drug on a preferred tier while another places it on a higher-cost tier or applies additional utilization rules.

Someone taking several medications can therefore compare the estimated annual drug cost rather than simply selecting the lowest-premium plan.

Health Insurance Before Age 65

Adults who are not yet Medicare eligible generally need another source of major medical coverage.

Possible sources can include:

Employer-sponsored insurance
Spouse's employer coverage
Retiree insurance
Individual Marketplace coverage
COBRA
Medicaid when eligible
Other qualifying health coverage

People approaching age 65 should understand when their Medicare eligibility begins before terminating existing coverage.

Health Insurance After Retirement

Retiring does not always occur at the same time as Medicare eligibility.

Someone retiring before 65 may need to bridge the period between employer insurance and Medicare.

Someone working beyond 65 may have a different coordination decision.

The size and type of employer coverage can influence Medicare enrollment considerations.

Before delaying Medicare Part B because of employer insurance, individuals can verify whether the coverage qualifies for the applicable Special Enrollment Period rules.

Comparing Senior Health Insurance Plans

A useful comparison should examine the complete plan rather than focusing only on premium.

Comparison Factor	What to Review
Monthly Premium	Regular plan cost
Medical Deductible	Amount before applicable coverage
Doctor Visits	PCP and specialist costs
Hospital Care	Inpatient/outpatient cost sharing
Maximum Out-of-Pocket	Annual medical spending protection
Prescriptions	Formulary and pharmacy costs
Provider Network	Doctors and hospitals
Dental	Covered services and limits
Vision	Exams and eyewear
Hearing	Exams and hearing aids
Travel	Emergency and non-emergency coverage
Prior Authorization	Services requiring approval

Using the same medications and preferred providers across each comparison can make differences easier to identify.

Conclusion

Health insurance for seniors in 2026 includes several different coverage structures, making it important to compare more than company names.

UnitedHealthcare, Humana, Aetna, Blue Cross Blue Shield and Wellcare all participate in significant parts of the Medicare market, but individual plan availability and benefits vary.

The choice between Original Medicare, Medicare Advantage and Original Medicare combined with supplemental coverage can affect provider access, prescription coverage, monthly premiums and out-of-pocket costs.

For Medicare Advantage comparisons, particularly important factors include the provider network, maximum out-of-pocket amount, prescription formulary, hospital cost sharing and supplemental benefits.

For Original Medicare beneficiaries considering Medigap and Part D, premiums and coverage from multiple private insurers can also be compared.

Reviewing the complete annual cost and confirming preferred doctors and prescriptions can provide a clearer comparison than choosing coverage based solely on an advertised monthly premium.
