Navigating Medicare can feel overwhelming, especially with all the unique terms and jargon. As a Las Vegas resident, understanding these terms is critical to making informed decisions about your healthcare. Whether you’re new to Medicare or looking to change your plan, this guide will break down the most common Medicare terms and explain how they apply to local plans and providers in Clark County, Neva
Original Medicare
Original Medicare refers to Parts A and B, which are managed by the federal government.
- Part A covers hospital stays, skilled nursing facilities, hospice care, and some home health services. In Las Vegas, this means coverage for inpatient care at local hospitals like Sunrise Hospital or University Medical Center (UMC).
- Part B covers outpatient care, including doctor visits, preventive services, and durable medical equipment. For example, it would cover your annual wellness visit at a primary care clinic in Las Vegas or lab tests ordered by your doctor.
Medicare Advantage (Part C)
Medicare Advantage plans are offered by private insurance companies and include all benefits of Parts A and B, often with additional coverage like dental, vision, hearing, and prescription drugs.
In Las Vegas, many Medicare Advantage plans are available, such as those from Humana, Aetna, and UnitedHealthcare. These plans often have provider networks, meaning you’ll need to choose doctors and hospitals within the plan’s local network to maximize your benefits.
Medicare Part D
Part D refers to prescription drug coverage and is offered through private insurance companies. Plans vary widely in their formularies (lists of covered drugs) and costs.
For Las Vegas beneficiaries, choosing a Part D plan means finding one that works with your preferred pharmacy, such as Walgreens, CVS, or Smith’s. Many plans also offer mail-order pharmacy options, which can be convenient for residents in Clark County.
Premium
A premium is the monthly amount you pay for your Medicare plan. While Part A is often premium-free if you’ve worked for 10 years or more, Part B premiums are standard and may increase based on your income.
For example, in 2025, the standard Part B premium is $174.70 per month, though this could vary for Las Vegas residents with higher incomes.
Deductible
A deductible is the amount you pay out-of-pocket before your Medicare plan begins to pay.
For instance, if your Part A deductible for 2025 is $1,600, you’ll need to pay this amount if you’re admitted to a hospital like Summerlin Hospital before Medicare covers the remaining costs.
Coinsurance
Coinsurance is the percentage you pay for services after you’ve met your deductible.
For example, under Part B, Medicare pays 80% of covered services, and you pay the remaining 20%. If you visit a specialist at Southwest Medical, you’ll be responsible for 20% of the Medicare-approved amount.
Copayment (Copay)
A copayment is a fixed dollar amount you pay for specific services.
For example, if you’re enrolled in a Medicare Advantage plan in Las Vegas, you may have a $25 copay for a primary care visit and a $50 copay to see a specialist.
Formulary
A formulary is the list of prescription drugs covered by a Medicare Part D or Medicare Advantage plan. Plans in Las Vegas often have different formularies, so it’s crucial to ensure your medications are covered. For instance, if you take insulin, you’ll want to confirm it’s included and check the tier it’s categorized under.
Network
A network refers to the group of doctors, hospitals, and providers that contract with your Medicare Advantage plan.
In Las Vegas, plans like Aetna Medicare Advantage or Humana HMO have specific networks. Visiting providers outside the network could result in higher costs or no coverage, so it’s essential to verify that your preferred doctors are in-network.
Medicare Supplement (Medigap)
Medigap plans are supplemental insurance policies that help cover out-of-pocket costs like deductibles, copayments, and coinsurance under Original Medicare.
For example, if you have a Medigap plan in Las Vegas, it could help pay for the 20% coinsurance not covered by Part B when you see a doctor at Centennial Hills Hospital.
Special Enrollment Period (SEP)
An SEP is a time outside of the Initial Enrollment Period or Annual Enrollment Period when you can make changes to your Medicare coverage due to qualifying life events.
For example, if you move to Las Vegas from another state, you’ll qualify for an SEP to choose a new plan that works with local providers and pharmacies.
