If you’re a Medicare beneficiary in Las Vegas or anywhere in Clark County, it’s crucial to understand how the Annual Enrollment Period (AEP) affects your coverage. Each fall, Medicare gives you the opportunity to evaluate, update, or switch your Medicare Advantage and Part D Prescription Drug plans. But many beneficiaries overlook this window or don’t fully understand its significance—often leaving money or better benefits on the table.
Let’s break down what AEP is, when it takes place, and how you can make the most of it in 2025.
What Is Medicare’s Annual Enrollment Period (AEP)?
The Annual Enrollment Period (AEP) is the time each year when people with Medicare can make changes to their Medicare Advantage (Part C) and Medicare Prescription Drug (Part D) coverage. This period allows you to switch plans, add or drop drug coverage, or go back to Original Medicare.
AEP is often confused with Initial Enrollment Period (IEP) (which is when you first sign up for Medicare) or Open Enrollment for Medigap (a separate window for Medicare Supplement plans). AEP is specifically about reviewing and possibly changing your existing Medicare Advantage or Part D plan for the upcoming year.
Key Dates for AEP 2025
October 15 to December 7, 2025
These dates are set by the federal government and apply to all Medicare beneficiaries nationwide, including those in Las Vegas, Henderson, and throughout Clark County, Nevada.
Here’s what you can do during this time:
- Switch from Original Medicare to a Medicare Advantage plan
- Switch from a Medicare Advantage plan back to Original Medicare
- Change from one Medicare Advantage plan to another
- Add, drop, or switch a Part D Prescription Drug Plan
Any changes you make during AEP will take effect January 1, 2026.
Why AEP Matters: Reviewing Your Coverage Can Save You Money
Even if you’re happy with your current plan, changes can happen every year that affect your benefits, costs, or provider access. Here are a few reasons why reviewing your plan during AEP is essential:
1. Premiums and Copays Can Change
Insurance companies update their pricing annually. Your plan may increase monthly premiums, change deductibles, or raise copayments. That bargain plan in 2024 may be less competitive in 2025.
2. Your Medications May No Longer Be Covered
Each Part D and Medicare Advantage plan with drug coverage has a formulary (a list of covered drugs). This list can change each year. If your medications are removed or moved to a higher tier, you could end up paying much more out of pocket.
3. Doctors and Pharmacies May Leave Your Network
If you’re on a Medicare Advantage plan, your preferred doctors, specialists, or hospitals might no longer be in-network in 2026. AEP is your opportunity to ensure you can still see the providers you trust.
4. New Plans Might Offer Better Benefits
New plans enter the Las Vegas market each year, and existing plans often enhance their benefits. Some plans may now include:
- Dental, vision, and hearing coverage
- Over-the-counter (OTC) allowances
- Transportation services
- Gym memberships like SilverSneakers®
- Grocery card benefits for those with chronic conditions
By working with a licensed Medicare agent during AEP, you can compare plans and potentially find one with better coverage or lower costs.
Common Mistakes People Make During AEP
Avoid these pitfalls to get the most out of your Medicare benefits:
❌ Not Reviewing Your Annual Notice of Change (ANOC)
Every September, your plan sends an Annual Notice of Change letter outlining what’s changing for next year. Ignoring this document could mean missing vital updates about your costs or benefits.
❌ Assuming Your Plan Is Still the Best Option
Even if your health hasn’t changed, your plan might not be as competitive as it once was. Prices, networks, and benefits change—review your options annually.
❌ Waiting Until the Last Minute
Many people wait until early December to start looking at their options. This puts pressure on decision-making and increases the chance of errors. Starting early gives you time to explore and ask questions.
How to Prepare for AEP 2025
✅ Make a List of Your Current Medications
Include the dosage, frequency, and whether you prefer brand-name or generics. This helps determine which plans offer the best value for your specific prescriptions.
✅ Confirm Your Preferred Doctors and Pharmacies
Check which plans include them in-network for 2026. This is especially important for specialists or those receiving ongoing care.
✅ Set Your Healthcare Budget
Know how much you can afford monthly for premiums and out-of-pocket expenses like copays and deductibles. Your agent can help find a plan that fits your budget.
✅ Keep an Eye on Plan Ratings
Medicare assigns Star Ratings to Medicare Advantage and Part D plans based on quality and performance. Plans with higher ratings typically offer better customer service, fewer complaints, and improved health outcomes.
✅ Work With a Local, Licensed Medicare Agent
Working with a knowledgeable, independent agent like Las Vegas Medicare ensures you’re reviewing all your options, not just one insurance company. We provide unbiased guidance and personalized help to find the plan that best suits your healthcare and financial needs.
Special Considerations for Las Vegas Medicare Beneficiaries
Las Vegas and Clark County have a highly competitive Medicare market. That’s good news for you—it means there are more options to choose from, including plans from:
- UnitedHealthcare
- Aetna
- Humana
- Wellcare
- Cigna
- Alignment
- Devoted Health
- And many more
But with more options comes more complexity. It’s easy to feel overwhelmed trying to compare everything yourself. At Las Vegas Medicare, we make the process easier by breaking down your options and giving you side-by-side comparisons based on your needs.
We’re also aware of local provider networks and which plans work best for certain hospitals and medical groups in Southern Nevada, such as:
- Dignity Health
- Intermountain Healthcare
- Southwest Medical
- Comprehensive Cancer Centers of Nevada
Whether you’re seeing a primary care physician in Summerlin, a specialist in Henderson, or a pharmacist in North Las Vegas, we can help you stay covered.
What Happens If You Miss AEP?
If you don’t make changes during AEP, your current plan will automatically renew—but with the updated 2026 costs and coverage. You won’t be able to make another change unless you qualify for a Special Enrollment Period (SEP) due to life events like moving, losing other coverage, or becoming eligible for Medicaid.
The next opportunity to make changes won’t come until:
- Medicare Advantage Open Enrollment Period: January 1 – March 31 (only for people already enrolled in a Medicare Advantage plan)
- AEP 2026: Starting October 15, 2026
