Medicare Advantage vs. Medicare Supplement Plans

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.

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:

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.
