Medicare Advantage vs. Medicare Supplement Plans

September 22, 2025

Two Popular Medicare Paths, One Important Choice

If you’re approaching Medicare eligibility, you’ve probably discovered that your choices don’t stop at Original Medicare (Parts A & B). Most people realize they’ll need additional coverage, either through a Medicare Advantage (Part C) plan or a Medicare Supplement (Medigap) policy.


Both options are designed to help protect your health and your wallet—but they work very differently. Choosing between them is one of the most important Medicare decisions you’ll make, and it can affect everything from your monthly costs to which doctors you can see.



At Solutions to Medicare, we’ve been guiding seniors in North Georgia, Chattanooga, TN, and Alabama for over a decade, and here’s what you should know before deciding.

What Is Medicare Advantage (Part C)?

Medicare Advantage, also called Part C, is offered by private insurance companies approved by Medicare. Instead of using Original Medicare, you receive your benefits through the Advantage plan.



Key Features of Medicare Advantage Plans:

  • Includes all the coverage of Parts A & B (hospital and medical insurance)
  • Often includes prescription drug coverage (Part D)
  • May bundle in extra benefits like dental, vision, hearing aids, transportation, or fitness memberships
  • Usually requires using a network of doctors, hospitals, and pharmacies
  • Costs include monthly premiums, copays, and coinsurance


  • Many people choose Medicare Advantage because it feels familiar—it operates like the employer health plans they’ve had in the past, with a single card, one network, and all-in-one benefits.

What Is Medicare Supplement (Medigap)?

Medicare Supplement Insurance (Medigap) works alongside Original Medicare. You keep Parts A & B, and your Medigap plan helps cover the “gaps” that Medicare leaves behind.


Key Features of Medigap Plans:

  • Helps pay deductibles, copayments, and coinsurance
  • Works with any doctor or hospital nationwide that accepts Medicare—no networks
  • Doesn’t typically include extras like dental or vision
  • Requires an additional monthly premium (on top of your Part B premium)
  • Gives you more predictable healthcare costs


People who want flexibility and travel often prefer Medigap, since it allows you to see specialists and providers across the country without referrals.

Head-to-Head Comparison: Medicare Advantage vs. Medigap

Feature Medicare Advantage (Part C) Medicare Supplement (Medigap)
Monthly Premiums Often lower Higher, but more predictable costs
Out-of-Pocket Costs Pay copays/coinsurance as you go Covers most out-of-pocket expenses
Provider Access Must use in-network doctors Any provider nationwide who accepts Medicare
Extra Benefits May include dental, vision, hearing, gym memberships Typically none
Prescription Drugs Often included Requires a separate Part D plan
Travel Coverage Usually local/regional networks Nationwide (and sometimes international emergency)

Questions to Ask Yourself Before Choosing

  • Do you travel frequently or spend time in more than one state?
  • Are your current doctors in-network for Advantage plans in your area?
  • Do you take regular prescriptions, and how are they covered in each plan?
  • Do you prefer lower premiums but more out-of-pocket costs—or higher premiums with fewer surprises?

Common Scenarios

  • Active, budget-conscious senior: Advantage may work well if you want low premiums and don’t mind using a network.
  • Frequent traveler or snowbird: Medigap is often the better fit since you’re not tied to one region’s network.
  • Chronic health conditions: Medigap can reduce frequent copays and give broader provider access.

How Solutions to Medicare Helps

Choosing between Advantage and Medigap isn’t easy, and the wrong choice can cost you money—or limit your access to care. That’s why our team at Solutions to Medicare takes a hands-on approach:

  • Review your prescriptions and doctors to see how they fit into different plans
  • Compare Advantage and Supplement plans side by side from multiple carriers
  • Explain the pros and cons in plain language so you know exactly what you’re choosing
  • Guide you through enrollment and provide ongoing support if your needs change later

The Right Medicare Choice Depends on You

There’s no single “best” Medicare plan. The right choice depends on your health, your budget, and your lifestyle. With personalized, local guidance from Solutions to Medicare, you don’t have to figure it out alone. We’ll help you choose the plan that fits your life today—and adapt as your needs change in the future.

If you are already enrolled in Medicare, the Open Enrollment Period, often called OEP, is one of the most important times of the year. This window gives you a chance to review your current coverage and make changes that better fit your health needs and budget for the year ahead. Understanding how Medicare OEP works can help you avoid unexpected costs, improve your coverage, and feel more confident about your healthcare decisions. What Is Medicare Open Enrollment Period? Medicare Open Enrollment runs every year from January 1 through March 31. This period is specifically for people who are already enrolled in a Medicare Advantage (Part C) plan. During OEP, eligible beneficiaries can make limited but meaningful changes to their Medicare coverage. Who Can Use Medicare OEP? Medicare OEP is available if you are currently enrolled in a Medicare Advantage plan. If you have Original Medicare only, this enrollment period does not apply to you. You can use OEP if: You are enrolled in a Medicare Advantage plan as of January 1 You want to change or drop your Medicare Advantage coverage What Changes Can You Make During OEP? During Medicare Open Enrollment, you can: Switch from one Medicare Advantage plan to another Drop your Medicare Advantage plan and return to Original Medicare Enroll in a standalone Part D prescription drug plan if you return to Original Medicare There are limits. You can only make one change during this period, and once that change is processed, it is final for the rest of the year unless you qualify for a Special Enrollment Period. What You Cannot Do During OEP Medicare OEP does not allow you to: Switch from Original Medicare to a Medicare Advantage plan Enroll in Medicare for the first time Change Medigap plans without underwriting in most states These types of changes typically happen during the Annual Enrollment Period in the fall. Why Medicare OEP Is Important Many people enroll in a Medicare Advantage plan during Annual Enrollment and later realize it does not fully meet their needs. Maybe your doctors are out of network, your prescriptions cost more than expected, or your copays are higher than you planned. OEP gives you a second chance to fix those issues without waiting an entire year. This period is especially helpful if: Your health needs changed You discovered your preferred doctors are not in network Your prescription costs are higher than expected You want more flexibility with Original Medicare When Do OEP Changes Take Effect? Changes made during Medicare Open Enrollment typically take effect on the first day of the month after your plan receives your request. For example, if you submit a change in February, your new coverage usually starts March 1. Tips for Making the Most of Medicare OEP Before making a change, take time to review: Your current medical and prescription costs Your doctors and whether they are in network Your preferred pharmacies Extra benefits you actually use, such as dental or vision It is also smart to compare total out-of-pocket costs, not just monthly premiums. A plan with a lower premium may cost more in copays over the year. Final Thoughts Medicare Open Enrollment Period is a valuable opportunity for Medicare Advantage members to reassess their coverage and make a smart adjustment if needed. Even if you are mostly satisfied with your plan, it is worth reviewing your options to ensure you are getting the best value for your situation. If you are unsure about your choices, speaking with a licensed Medicare professional can help you understand your options and avoid costly mistakes. Taking a little time during OEP can make a big difference in your healthcare experience for the rest of the year.

A new year is a natural time to review important parts of your life, including your health coverage. For many people on Medicare, changes in premiums, benefits, and personal health needs can quietly add up. Starting the year with a clear understanding of your Medicare options can help you avoid surprises and feel more confident about the months ahead. Why the New Year Is the Right Time for a Medicare Review Medicare plans do not always stay the same from year to year. Even small changes can affect your budget and access to care. The start of the year is a smart time to review your coverage because: Premiums and cost sharing may have changed Prescription needs often evolve over time Provider networks and coverage rules can shift Many people are still unclear about what their plan actually covers A review helps ensure your coverage still aligns with your needs and priorities. Common Issues Found During Medicare Reviews Many Medicare beneficiaries discover issues only after a claim is denied or a bill arrives. A proactive review often uncovers: Higher out-of-pocket costs than expected Coverage that no longer matches current health needs Overlapping benefits that increase monthly costs Missed opportunities to simplify coverage Identifying these issues early in the year can prevent unnecessary stress later on. Medicare Supplement Plans and Peace of Mind Medicare Supplement plans are designed to help cover costs that Original Medicare does not, such as deductibles and coinsurance. When reviewed properly, a supplemental plan can provide see-any-doctor flexibility and more predictable expenses throughout the year. A New Year review helps confirm whether your current supplement still offers the value and stability you expect. Start the Year With Clarity, Not Confusion Medicare decisions do not need to be rushed or overwhelming. Taking time now to review your options allows you to make informed choices based on your health, budget, and long-term goals. The New Year is not about making changes for the sake of change. It is about making sure your Medicare coverage continues to work for you. Make This the Year You Feel Confident About Medicare If you have questions about your coverage or simply want reassurance that you are on the right plan, a Medicare review can provide clarity and peace of mind. Starting the year informed is one of the best resolutions you can make.

Many Medicare beneficiaries receive a notice that their current coverage is under review or no longer meeting their needs. This can happen due to rising premiums, changes in health needs, or confusion about benefits that were never fully explained. While this situation can feel stressful, it is also an opportunity to make sure your Medicare Supplemental plan truly fits your needs. Why Medicare Supplemental Plans Get Reviewed A Medicare Supplement plan, also called Medigap, is designed to help cover out-of-pocket costs that Original Medicare does not pay. Over time, several factors can trigger a review of your coverage: Premiums increase each year without added value Health needs change, leading to higher medical expenses Benefits overlap or fail to cover frequent services The plan was chosen without a full comparison of options A review does not automatically mean your plan is bad, but it does mean it is worth taking a closer look. Common Gaps Found During a Review During a Medicare Supplemental plan review, many people discover gaps they did not realize existed, such as: Limited coverage for frequent doctor visits Higher-than-expected out-of-pocket costs A plan that costs more than similar options in the same area Benefits that no longer align with current prescriptions or providers Identifying these gaps early can prevent unnecessary expenses later in the year. How a Medicare Supplement Review Helps You A proper review focuses on understanding your situation, not pushing a one-size-fits-all solution. A thoughtful review can help you: Compare plans side by side using your current doctors and usage Identify ways to lower premiums without sacrificing coverage Confirm whether switching plans makes sense or if staying put is best Gain clarity and peace of mind about your Medicare choices The goal is not always to change plans, but to confirm that your current plan is still working for you. When to Consider Making a Change You may want to explore new supplemental options if: Your premiums have increased significantly You are paying out of pocket more often than expected You feel unsure about what your plan actually covers Your health needs or budget have changed Timing matters, and certain enrollment periods offer more flexibility, so guidance is important. Take the Guesswork Out of Medicare Decisions Medicare does not have to be confusing or overwhelming. A clear, personalized review of your supplemental plan can uncover better solutions and help you move forward with confidence. If your Medicare coverage is under review, take it as a chance to ask questions, compare options, and make sure your plan truly supports your health and financial goals.

When you delay Medicare Part B because you are still working and covered under an employer plan, you will need specific forms to enroll later without penalties. These forms confirm that you had qualifying coverage, and getting them completed correctly can save you money and stress. This guide explains what the forms are, why they matter, and how to get them from your employer. The Two Forms You Need When you are ready to enroll in Part B after age 65, you usually submit two forms together: Form CMS 40B This is the Medicare Part B application. You fill it out yourself. Form CMS L564 This is the Request for Employment Information. Your employer fills out part of it to verify that you had active employer group health coverage. Both forms work together to show Medicare that you qualify for a Special Enrollment Period. This allows you to sign up for Part B without a late enrollment penalty. Why the Employer Form Matters Medicare needs proof that you were covered by active employer health insurance, not retiree coverage or COBRA. The L564 form provides that proof. Without it, Medicare may charge you higher premiums for waiting to enroll. How To Get the Employer Form Completed Step 1: Download the Form You can find Form CMS L564 on the official Medicare or Social Security website. It is a simple one page document. Step 2: Contact Your HR or Benefits Office Reach out to the team that manages your health insurance. Let them know you need Form L564 completed for Medicare. Most HR offices are familiar with it and can return it quickly. Step 3: Provide Any Needed Details Some employers ask for your hire date or proof of current coverage. Having your insurance card and employment history handy can make the process smoother. Step 4: Check That the Form Is Fully Completed Your employer should fill out Section B, sign it, and include their contact information. Double check that nothing is missing. Medicare will not process an incomplete form. Step 5: Submit the Forms Together Send CMS 40B and CMS L564 to Social Security. You can do this by mail, by fax, or by dropping them off at your local office. Many people choose to upload the forms through the online Social Security portal for faster processing. Tips for a Smooth Experience Request the form early so you are not rushing near your enrollment deadline. Keep copies of everything you submit. If you had coverage through multiple employers, you may need separate L564 forms. Ask your HR office who to contact if Medicare needs follow up verification. Final Thoughts Getting employer forms for Medicare is usually straightforward once you know what to ask for. These documents protect you from penalties and allow you to transition from employer coverage to Medicare with confidence. A bit of planning and clear communication with your HR team can make the entire process much easier.

Stepping into Medicare can feel like learning a new language. Deadlines, parts, and plan choices all arrive at the same time, and it is easy to wonder where to start. The good news is that the process is more straightforward once you understand the timeline and what each part of Medicare actually covers. This guide walks through the essentials so readers can approach enrollment with confidence. When You Can Enroll Your first chance to sign up is called the Initial Enrollment Period. It starts three months before the month you turn 65, includes your birthday month, and continues for three months after. Enrolling early helps you avoid gaps in coverage and cuts down on surprises. If you already receive Social Security benefits, you are usually signed up for Medicare Part A and Part B automatically. If not, you will need to enroll on your own. The Four Parts of Medicare Medicare is divided into parts, each covering different services: Part A Hospital insurance. It covers inpatient stays, skilled nursing care, some home health services, and hospice. Most people qualify for Part A with no monthly premium. Part B Medical insurance. It covers doctor visits, outpatient care, preventive services, and durable medical equipment. Part B does have a monthly premium. Part C (Medicare Advantage) These are plans offered by private insurers that bundle Part A, Part B, and often Part D. Many also include dental, vision, and hearing benefits. Part D Prescription drug coverage. Part D plans vary, so comparing formularies, premiums, and pharmacy networks is important. How To Sign Up You can enroll in Medicare in a few different ways: Online at the Social Security Administration website By phone with Social Security In person at your local Social Security office Most people find the online application simple and quick. Before starting, it helps to have your Social Security number, current insurance details, and a list of prescription medications ready. What Happens If You Delay Putting off enrollment can lead to lifetime penalties for Part B and Part D unless you qualify for a Special Enrollment Period. This applies if you or your spouse still have active employer coverage when you turn 65. Once that coverage ends, you get an eight month window to enroll without a penalty. Choosing the Right Coverage After signing up for Parts A and B (also called Original Medicare), you decide whether to stay with Original Medicare or switch to a Medicare Advantage plan. If you stay with Original Medicare, you can add a Part D plan and a Medigap policy to help with out of pocket costs. Your choice depends on your doctors, your medications, your budget, and how much flexibility you want. Shopping around each year during the Annual Enrollment Period can save you money and help you stay matched with the right plan. Final Thoughts Medicare does not have to be overwhelming. When you understand the enrollment window, what each part covers, and how to sign up, the process becomes far more manageable. A little preparation goes a long way in making sure your health coverage fits your needs as you move into the next stage of life.
