Medicare Coverage: Medicare Advantage vs. Original Medicare + Medigap + Part D – Which Option Is Right for You?

Choosing Medicare is one of the most important financial and healthcare decisions you’ll make in retirement. Every year, thousands of Floridians ask the same question:

Should I enroll in a Medicare Advantage plan, or should I keep Original Medicare (Parts A & B), purchase a Medicare Supplement (Medigap) policy, and add a standalone Part D prescription drug plan?

The truth is there isn’t a one-size-fits-all answer. The best option depends on your health, budget, travel habits, preferred doctors, and prescription medications.

At Health Insurance Santa Claus, our job isn’t to push one option over another—it’s to help you understand your choices so you can make an informed decision.

In this guide, we’ll compare both options, discuss the advantages and disadvantages of each, and explain who may benefit most from each type of coverage.

Understanding Your Two Main Medicare Choices

Once you’re enrolled in Original Medicare Part A and Part B, you generally have two ways to receive your Medicare benefits:

Option 1:

Original Medicare

Part A (Hospital Insurance)
Part B (Medical Insurance)
Medicare Supplement (Medigap)
Standalone Part D Prescription Drug Plan

Option 2:

Medicare Advantage (Part C)

Most Medicare Advantage plans combine:

Part A
Part B
Prescription Drug Coverage (Part D)

Many also include additional benefits like dental, vision, hearing, fitness memberships, transportation assistance, and more. Medicare.gov provides an official comparison of Original Medicare and Medicare Advantage, including provider access, costs, prior authorization, and drug coverage.

Original Medicare + Medigap + Part D

Many people refer to this as the “traditional Medicare” option.

Original Medicare pays its share of approved healthcare costs, while a Medigap policy helps cover many of the remaining deductibles, copays, and coinsurance. Since Medigap plans don’t include prescription coverage, you’ll also enroll in a separate Part D drug plan.

Advantages

Freedom to Choose Your Doctors

Perhaps the biggest benefit is flexibility.

You may see any doctor or hospital in the United States that accepts Medicare, without worrying about provider networks.

This can be especially valuable if you:

Travel frequently
Live in multiple states during the year
Want access to major specialty hospitals
Already have physicians you don’t want to change

No Network Restrictions

Unlike many Medicare Advantage plans, Original Medicare generally doesn’t limit you to a provider network.

You don’t have to worry whether your cardiologist, orthopedic surgeon, or cancer specialist is “in-network.”

Fewer Prior Authorization Requirements

Original Medicare generally does not require prior authorization for many medically necessary services that may require approval under some Medicare Advantage plans.

Predictable Medical Expenses

One of the reasons many beneficiaries purchase Medigap coverage is predictability.

Depending on the Medigap plan selected, many out-of-pocket medical costs can be significantly reduced, making healthcare expenses easier to budget throughout the year. Medicare.gov offers a standardized comparison of Medigap plan benefits.

Excellent for Frequent Travelers

If you travel throughout the United States or spend winters in Florida and summers elsewhere, Original Medicare often provides greater flexibility.

Certain Medigap plans may also include limited emergency foreign travel coverage.

Disadvantages of Original Medicare + Medigap

Higher Monthly Premiums

This option usually involves paying:

Part B premium
Medigap premium
Part D premium

While medical expenses may become more predictable, monthly premiums are often higher than Medicare Advantage.

No Extra Benefits Included

Original Medicare generally doesn’t include:

Routine dental
Routine vision
Hearing aids
Fitness memberships

These services may require separate insurance or out-of-pocket payment.

Separate Drug Plan Required

Prescription coverage isn’t included.

You’ll need to enroll in a standalone Part D plan to help pay for medications and to avoid potential late enrollment penalties if you delay enrolling without other creditable drug coverage.

Medicare Advantage Plans

Medicare Advantage plans are offered by private insurance companies approved by Medicare.

They provide all Part A and Part B benefits and often include prescription drug coverage as well.

Many plans also include additional benefits beyond what Original Medicare covers.

Advantages of Medicare Advantage

Lower Monthly Premiums

Many Medicare Advantage plans have very low—or even $0—additional monthly premiums beyond the Part B premium.

This makes them attractive for individuals looking to reduce monthly healthcare costs.

Built-In Prescription Drug Coverage

Most Medicare Advantage plans already include Part D prescription drug coverage.

That means:

One insurance card
One plan
One premium in many cases

Extra Benefits

Many plans include benefits that Original Medicare doesn’t cover, such as:

Dental care
Vision exams
Eyewear allowances
Hearing exams
Hearing aid benefits
Fitness memberships
Telehealth services
Over-the-counter benefit allowances (on some plans)
Transportation benefits (on some plans)

Benefits vary by plan and county.

Annual Maximum Out-of-Pocket Limit

Unlike Original Medicare alone, Medicare Advantage plans include an annual maximum out-of-pocket limit for covered Part A and Part B services. Once you reach that limit, the plan pays 100% of covered medical costs for the remainder of the year. Original Medicare does not have this type of limit unless you have supplemental coverage such as Medigap.

Convenient All-in-One Coverage

Many beneficiaries appreciate having:

Medical
Hospital
Drug coverage

all managed through one plan.

Disadvantages of Medicare Advantage

Provider Networks

Most Medicare Advantage plans use provider networks such as HMOs or PPOs.

Depending on your plan:

You may need to use network doctors.
Out-of-network services may cost more.
Some HMOs require referrals for specialists.

Before enrolling, it’s important to verify that your preferred physicians and hospitals participate in the plan’s network.

Prior Authorization

Some services may require prior authorization before the plan covers them.

Although this process is designed to ensure medical necessity, it can sometimes delay treatment if approval is required.

Benefits Can Change Each Year

Medicare Advantage plans are renewed annually.

Each year, items such as:

Premiums
Copays
Provider networks
Drug formularies
Extra benefits

can change.

That’s why reviewing your Annual Notice of Change (ANOC) every fall is so important.

Coverage Is Local

Because Medicare Advantage plans are generally based on service areas, moving to another county or state may require selecting a different plan.

Which Option Is Better?

The honest answer is:

It depends on your individual situation.

Original Medicare + Medigap may be better if you:

Travel frequently
Want maximum doctor flexibility
See multiple specialists
Prefer predictable medical expenses
Don’t mind paying higher monthly premiums

Medicare Advantage may be better if you:

Want lower monthly premiums
Prefer bundled coverage
Value extra dental, vision, and hearing benefits
Primarily receive care locally
Are comfortable using provider networks

Questions to Ask Before Choosing

Before enrolling, consider:

Are all of my doctors in-network?
What prescriptions do I take?
How often do I travel?
Can I comfortably afford higher monthly premiums?
Would predictable medical costs give me peace of mind?
Do I want dental, vision, and hearing benefits included?

These questions often have a greater impact than simply comparing premiums.

Don’t Forget About Part D

If you choose Original Medicare with a Medigap policy, you’ll usually need a standalone Medicare Part D prescription drug plan.

Even if you currently take few or no medications, enrolling in Part D when you’re first eligible may help you avoid a permanent late enrollment penalty if you need drug coverage later and don’t have other creditable prescription coverage.

Final Thoughts

There is no universally “best” Medicare option—only the option that’s best for you.

Some beneficiaries prioritize nationwide access to providers and predictable out-of-pocket costs, making Original Medicare paired with Medigap and Part D an attractive choice. Others value lower monthly premiums, bundled coverage, and additional benefits like dental, vision, and hearing, making Medicare Advantage a better fit.
