How Medicare Advantage works—and what to compare before choosing a plan.
Medicare Advantage can combine hospital, medical and often prescription drug coverage into one private Medicare plan. But provider networks, costs, drug coverage and plan rules can differ substantially.
What Should I Compare? ↓More than a monthly premium.
What is Medicare Advantage?
Medicare Advantage, also called Medicare Part C, is another way to receive Medicare Part A and Part B benefits.
Instead of receiving those benefits directly through Original Medicare, you enroll in a Medicare-approved health plan offered by a private insurance company.
You remain in the Medicare program, but the Medicare Advantage plan administers your covered healthcare benefits according to the plan's rules.
Most Medicare Advantage plans also include Medicare Part D prescription drug coverage, and many offer additional benefits that Original Medicare does not routinely cover, such as certain dental, vision or hearing benefits. :contentReference[oaicite:1]{index=1}
You generally must have Medicare Part A and Part B to enroll in a Medicare Advantage plan, and you usually continue paying your Medicare Part B premium in addition to any premium charged by the plan.
HMO vs. PPO: one of the first distinctions to understand.
The letters may look minor, but they can materially affect which doctors you can see, whether referrals are required and what happens when you receive non-emergency care outside the network.
Health Maintenance Organization
HMO plans generally emphasize receiving care through participating network providers.
- You usually select or use providers within the plan network.
- Non-emergency out-of-network care may not be covered.
- Some plans require referrals for specialist care.
- Emergency and urgent care rules are different from routine network care.
Preferred Provider Organization
PPO plans generally offer more flexibility to use providers outside the plan's preferred network.
- You typically pay less when using in-network providers.
- Out-of-network covered care may cost more.
- Specialist referrals generally aren't required.
- Always verify that an out-of-network physician will accept the plan.
Medicare describes several Medicare Advantage plan structures in addition to HMOs and PPOs, including Special Needs Plans and certain Private Fee-for-Service and Medical Savings Account plans. Availability varies. :contentReference[oaicite:2]{index=2}
Don't start with the premium. Start with these six questions.
A plan that looks inexpensive can become much less attractive if your doctors aren't in-network, an important medication isn't favorably covered, or your normal healthcare requires substantial cost sharing.
Are my doctors in-network?
Check your primary care physician, specialists and other clinicians you want to continue seeing.
Are my hospitals in-network?
Look beyond individual physicians. Confirm preferred hospitals, medical groups and major health systems as well.
How are my prescriptions covered?
Each Medicare drug plan has its own formulary. Check medication tiers, restrictions and pharmacy options rather than assuming coverage is the same.
What will I pay when I use care?
Compare specialist copays, hospital costs, diagnostic imaging, outpatient procedures and other services you may realistically use.
What is the maximum out-of-pocket exposure?
A low monthly premium does not tell you your potential annual healthcare cost if you become seriously ill or require extensive treatment.
What happens when I travel?
If you routinely leave Nevada or spend part of the year elsewhere, understand the plan's rules for non-emergency care outside its service area.
The plan is only as useful as the network you can actually access.
Provider network evaluation deserves particular attention when comparing Medicare Advantage plans.
A beneficiary in Reno may care about access to particular Northern Nevada physicians and hospitals. Someone in Las Vegas or Henderson may have a completely different set of preferred medical groups, hospitals and specialists.
For rural Nevada residents, network depth and geographic access may be even more important.
Consider specialists you already see, preferred hospitals, cancer centers, outpatient surgery facilities, rehabilitation providers, durable medical equipment suppliers and other services that could become important.
Provider directories can change, so confirm important providers directly with the plan and provider rather than relying solely on an old directory or advertisement.
What is prior authorization?
Some Medicare Advantage services may require plan approval before coverage.
Medicare notes that Medicare Advantage beneficiaries typically need prior authorization before a plan covers certain services or supplies. :contentReference[oaicite:3]{index=3}
Beginning in 2026, applicable payers, including Medicare Advantage organizations, are subject to new federal prior-authorization requirements for certain medical items and services, including decision timeframes and specific reasons for denials. CMS states that standard decisions generally must be made within seven calendar days and expedited decisions within 72 hours under these requirements. :contentReference[oaicite:4]{index=4}
Prior authorization isn't necessarily a reason to reject Medicare Advantage, but it is an important operational difference to understand—especially for people who regularly require specialty care, procedures, imaging or other complex services.
Don't assume your medications are covered the same way by every plan.
Most Medicare Advantage plans include Part D prescription drug coverage.
Each drug plan has its own list of covered medications, called a formulary. Plans may place medications on different tiers and may use requirements such as prior authorization. :contentReference[oaicite:5]{index=5}
When comparing plans, look at more than whether a medication appears on the formulary.
- What tier is the medication on?
- What is the expected copay or coinsurance?
- Is prior authorization required?
- Does step therapy apply?
- Is your preferred pharmacy in the plan's network?
- Would a preferred pharmacy or mail-order option reduce your cost?
Make a current medication list before comparing Medicare Advantage plans. Use the exact drug, dose and frequency when possible.
Four numbers matter more than the advertised premium alone.
Monthly premium
Some plans charge an additional plan premium while others may advertise a low or $0 plan premium. You generally continue paying your Part B premium.
Copays & coinsurance
Understand what you pay when seeing specialists, receiving imaging, having procedures or using hospital services.
Drug costs
Prescription costs depend on the plan's formulary, tiers, pharmacy network and benefit structure.
Maximum out-of-pocket
Medicare Advantage plans have an annual limit on what beneficiaries pay for covered Part A and Part B services. The amount varies by plan.
Medicare confirms that Medicare Advantage out-of-pocket limits vary by plan and that, once the plan's annual limit for covered health services is reached, the plan pays covered health-service costs for the remainder of the calendar year according to Medicare rules. :contentReference[oaicite:6]{index=6}
Dental, vision and hearing benefits can be valuable—but compare the details.
Many Medicare Advantage plans offer benefits beyond what Original Medicare routinely covers, such as dental, vision or hearing services. :contentReference[oaicite:7]{index=7}
These benefits can certainly matter, but they shouldn't overshadow the core medical coverage.
Before choosing a plan primarily because of an extra benefit, examine the actual benefit structure.
- Is there an annual allowance or maximum?
- Are particular providers required?
- Does the benefit cover preventive services only?
- Are copays or coinsurance involved?
- Are there restrictions or exclusions?
Provider access, prescription coverage, hospital costs and maximum out-of-pocket exposure can have much greater financial consequences than a modest dental or vision allowance.
Medicare Advantage is local.
Medicare Advantage plan availability is based on geographic service areas, so the plans available to a resident of one Nevada ZIP code may differ from those available elsewhere in the state.
That makes ZIP code one of the first pieces of information needed for any meaningful Medicare Advantage comparison.
NevadaHealthPlans.com therefore organizes resources around communities including:
- Reno and Sparks
- Las Vegas
- Henderson
- Carson City
- Elko
- Rural Nevada
Medicare's official Plan Compare tool similarly begins with location information to show available health and drug plans. :contentReference[oaicite:8]{index=8}
