Medicare Annual Enrollment 2026: Your Complete Guide Before the December 7 Deadline

Medicare Annual Enrollment 2025: Your Complete Guide Before the December 7 Deadline

Time-Sensitive: You have until December 7, 2025, to make changes to your Medicare coverage for 2026

The clock is ticking. Right now, millions of Medicare beneficiaries are in the middle of the Annual Enrollment Period - the narrow window each year when you can make changes to your Medicare coverage. Whether you're happy with your current plan or sensing something's off, what you decide (or don't decide) in the next few weeks will impact your healthcare and finances for all of 2026.

This isn't just another administrative task to put off. Your current plan may have changed dramatically for 2026-even if you haven't changed at all.

What Is Medicare Annual Enrollment Period?

The Medicare Annual Enrollment Period runs from October 15 through December 7 every year, giving you nearly eight weeks to review and modify your Medicare coverage. Any changes you make during this period take effect on January 1, 2026.

Think of it as your annual opportunity to course-correct. Last year's perfect plan might be this year's expensive mistake.

What You Can Change During Annual Enrollment

During this period, you have wide-ranging flexibility:

Switch Medicare Types

• Move from Original Medicare to Medicare Advantage
• Switch from Medicare Advantage back to Original Medicare
• Change from one Medicare Advantage plan to another

Modify Drug Coverage

• Join a Medicare Part D prescription drug plan
• Switch between Part D plans
• Drop Part D coverage (though this can trigger penalties)

Adjust Your Coverage Level

• Switch from a Medicare Advantage plan without drug coverage to one with it
• Add or remove supplemental benefits

Why This Year's Enrollment Is Especially Critical

Major Changes Taking Effect in 2026

One of the biggest changes is the $2,000 cap on out-of-pocket prescription drug costs that took effect in 2026. This change continues to reshape how Part D and Medicare Advantage plans structure their costs and coverage.

The cap includes out-of-pocket expenses and certain payments made by other entities, such as Medicare's Extra Help program, but only applies to drugs covered under Medicare prescription drug plans.

Your Plan Changed Even If You Didn't

Here's what most people don't realize: The share of Medicare Advantage plans offering certain benefits has declined significantly, including over-the-counter benefits (from 85% in 2024 to 73% in 2026), remote access technologies (from 74% to 53%), meal benefits (from 72% to 65%), and transportation (from 36% to 30%).

Insurance companies can modify:

• Monthly premiums
• Deductibles and copayments
• Provider networks (which doctors and hospitals are covered)
• Prescription drug formularies (which medications are covered)
• Extra benefits like dental, vision, and gym memberships

That Medicare Advantage plan that was perfect last year? It might have cut benefits, raised costs, or dropped your doctor from the network.

The Numbers Behind the Changes

In 2025, 54% of Medicare beneficiaries are enrolled in Medicare Advantage-more than half of all eligible beneficiaries. While the total number of Medicare Advantage plans declined by 6% (from 3,959 to 3,719), most beneficiaries still have robust choices.

In 2025, the standard Part B premium is $202.90 per month with a deductible of $283 annually, representing increases that impact everyone's healthcare budget.

Understanding Your Medicare Options

Original Medicare (Parts A & B)

What It Covers

Part A provides hospital insurance and Part B provides medical insurance for physician visits and outpatient care.

2025-2026 Costs

Most beneficiaries pay no premium for Part A if they paid Medicare taxes. Part B requires a $202.90 monthly premium with a $283 annual deductible. Part A has a $1,676 deductible for inpatient hospitalizations.

Part B services are subject to coinsurance of 20 percent with no out-of-pocket maximum, meaning costs can theoretically be unlimited without supplemental coverage.

Pros:

• Freedom to see any doctor who accepts Medicare nationwide
• No network restrictions
• Consistent coverage across the country
• Predictable structure

Cons:

• No prescription drug coverage (requires separate Part D)
• No out-of-pocket maximum
• 20% coinsurance on most services adds up quickly
• No coverage for dental, vision, or hearing
• Typically requires Medigap supplemental insurance

Medicare Advantage (Part C)

What It Includes

Medicare Advantage plans cover all benefits under Medicare Part A, Part B, and in most cases Part D, and typically offer extra benefits such as dental services, eyeglasses, and hearing exams.

2025-2026 Costs

In 2025, three quarters (76%) of Medicare Advantage enrollees are in plans that charge no additional premium apart from the Part B premium. The average monthly premium for Medicare Advantage plans is projected to be $17.00 in 2026.

Medicare Advantage plans are required to include a cap on out-of-pocket expenses. In 2025, this cap may not exceed $9,350 for in-network services or $14,000 for all covered services, though most plans have lower limits averaging $5,320 for in-network services.

Pros:

• Often $0 or low monthly premiums
• Capped out-of-pocket costs
• Prescription drug coverage usually included
• Extra benefits (dental, vision, hearing, gym, OTC items)
• All-in-one convenience

Cons:

• Network restrictions (must use plan providers)
• May need referrals for specialists
• Coverage limited to service area
• Plans can change significantly year to year
• Prior authorization requirements

Medicare Part D (Prescription Drug Coverage)

If you choose Original Medicare, you'll need standalone Part D coverage to get prescription drug benefits.

2025-2026 Changes

The average stand-alone monthly premium for a Medicare Part D prescription drug plan is projected to be $46.50 in 2026.

In 2025, Part D plans can have a deductible of up to $590. The big news is the $2,000 out-of-pocket cap that helps millions avoid catastrophic drug costs.

How to Navigate Annual Enrollment: Step-by-Step

Step 1: Gather Your Documents (Days 1-2)

You'll Need:

• Your Annual Notice of Change (ANOC) mailed in September
• Current plan details and ID card
• Complete list of prescription medications (names, dosages, frequencies)
• List of doctors and specialists you see regularly
• Medical history and anticipated healthcare needs for 2026

The ANOC is crucial-it outlines every change your plan is making for 2026. Don't skip reading it.

Download our comprehensive Annual Enrollment Period Checklist to ensure you don't miss any important documents or steps.

Step 2: Review Your Current Coverage (Days 3-4)

For Medicare Advantage enrollees:

• What's changing in your plan's costs?
• Are your doctors still in-network?
• Are your prescriptions still covered?
• What benefits are being added or removed?

For Original Medicare + Part D:

• Is your Part D formulary changing?
• Are your drug costs increasing?
• Would a different plan save you money?

Step 3: Assess Your Healthcare Needs for 2026

Think honestly about:

Your Doctors

• Do you need to keep your current providers?
• Are you willing to change doctors for lower costs?
• Do you need specialists or just primary care?

Your Medications

• Have your prescriptions changed?
• Are you on expensive specialty drugs?
• Do you anticipate new medications?

Your Health Status

• Are you managing chronic conditions?
• Do you expect surgeries or procedures?
• Has your health changed significantly?

Your Budget

• What can you afford in monthly premiums?
• How much can you handle in copays?
• Do you value extra benefits like dental?

Your Lifestyle

• Do you travel frequently?
• Do you spend time in multiple states?
• Do you need nationwide coverage?

Step 4: Compare Plans Using Medicare.gov (Days 5-7)

The Medicare Plan Finder at Medicare.gov/plan-compare is your most powerful tool.

Visit our Annual Enrollment Period page for tools, checklists, and resources to help you compare plans effectively.

The best way to enroll in a new plan is via the Medicare Plan Finder website or by calling 1-800-MEDICARE.

How to Use It Effectively:

1. Enter your exact zip code - Plans vary dramatically by location
2. Add ALL your prescriptions - Include exact names, dosages, and pharmacy
3. List your doctors - Verify they're in-network
4. Compare total annual costs - Not just monthly premiums
5. Check plan star ratings - Quality matters (aim for 4-5 stars)

CRITICAL: Focus on total estimated annual cost, not monthly premium. A $0 premium plan might cost you $3,000 more annually due to higher copays and drug costs.

Common Mistakes to Avoid

Avoiding these common mistakes can save you thousands of dollars and ensure you get the coverage you need. For a complete guide on what to watch out for during enrollment, visit our Annual Enrollment Period page.

Mistake #1: Ignoring Annual Enrollment Entirely

Assuming your plan is fine without checking is risky. Despite changes in plan offerings, most Medicare beneficiaries report that they do not compare coverage options on an annual basis.

Your plan can change dramatically without your knowledge or consent. Don't learn about higher costs or dropped coverage when you need care in February.

Mistake #2: Focusing Only on Monthly Premium

A $0 premium doesn't mean free healthcare. Look at:

• Deductibles
• Copays for doctor visits
• Coinsurance rates
• Prescription drug costs
• Out-of-pocket maximums
• Total estimated annual cost

Mistake #3: Not Verifying Your Drug Coverage

Formularies change every year. A medication that was tier 1 (lowest cost) might become tier 3 or be removed entirely. This can cost you hundreds of dollars monthly.

Mistake #4: Ignoring Network Changes

Your doctor being in-network last year means nothing for 2026. Always verify current network status-don't assume.

Mistake #5: Falling for Marketing Gimmicks

Free grocery cards, gym memberships, and OTC allowances are nice extras, but they shouldn't drive your decision. Many plans have reduced supplemental benefits. Focus on core medical coverage and prescription drug costs first.

Mistake #6: Waiting Until December 7

The Medicare Annual Enrollment Period runs through December 7. Waiting until the last day leaves no room for mistakes, questions, or enrollment problems. Start now.

Mistake #7: Not Reading Plan Star Ratings

Star ratings (1-5 stars) measure plan quality based on customer satisfaction, staying healthy, getting care, and member complaints. Plans with 4-5 stars generally provide better service.

Nearly one-third of beneficiaries (31%) in 169 counties can choose from plans offered by 10 or more firms, giving most people solid options.

The Bottom Line

Medicare Annual Enrollment isn't optional, it's not tedious paperwork, and it's definitely not something to put off. It's your annual opportunity to take control of your healthcare costs and coverage.

What worked last year might cost you thousands more in 2026. Plans change. Your health changes. Your medications change. The only way to ensure you have the right coverage is to review your options every single year during Annual Enrollment.

You have until December 7, 2025. That deadline will arrive faster than you think.

Don't leave money on the table. Don't risk being stuck with coverage that doesn't meet your needs. Don't wait until December 6 to start looking.
