Medicare Advantage vs. Medigap: A Guide for The Villages Area
You've enrolled in Medicare Part A and B. Now you're comparing two common coverage approaches: Medicare Advantage and Medigap. Here's how they differ in cost, provider access, prescriptions, and enrollment rules.

The Two Common Approaches
After you have Original Medicare (Part A and Part B), you may choose one of two common coverage approaches. Some people have other supplemental coverage, such as employer or retiree coverage or Medicaid, and don't need either one.
Medicare Advantage (Part C)
A private, Medicare-approved plan that provides your Medicare Part A and Part B benefits. Most plans also include Part D prescription drug coverage. You enroll with one insurance company, use its network of providers, and follow the plan's rules for referrals, authorizations, and cost-sharing.
You still pay your Part B premium. The plan may charge its own premium, copays, and coinsurance, and may offer extra benefits like dental, vision, hearing, fitness, or over-the-counter allowances.
Medigap (Medicare Supplement Insurance)
A supplemental insurance policy that works alongside Original Medicare. Depending on the policy, Medigap helps pay specified out-of-pocket costs that Original Medicare leaves to you, such as deductibles, coinsurance, and copayments.
Medigap does not pay every expense Medicare does not cover. It does not pay Medicare Advantage cost-sharing. Medigap policies sold today do not include Part D prescription drug coverage, so you would add a separate Part D plan for prescriptions.
Key Differences at a Glance
Monthly Costs
Medicare Advantage
Premiums vary by plan; some plans have a $0 monthly premium. A $0 plan premium does not mean all healthcare is free. You generally remain responsible for your Part B premium unless assistance or a plan benefit helps pay it. Copays and coinsurance vary by service and plan.
Medigap
Medigap premiums vary by plan letter, insurer, your age at purchase, ZIP code, and tobacco status. You also pay your Part B premium and, if applicable, a separate Part D premium. Cost-sharing for covered services depends on the specific Medigap plan.
Doctor Choice & Networks
Medicare Advantage
Provider rules depend on the plan type:
- • HMOs generally require network care, with exceptions including emergency care, out-of-area urgent care, and temporary out-of-area dialysis. Some HMO-POS plans allow additional out-of-network services.
- • PPOs generally allow covered out-of-network services, usually at higher cost.
- • Confirm both the plan's coverage and the provider's willingness to treat you, since participation can change.
Original Medicare with standard Medigap
You can generally use providers nationwide who accept Medicare. Not every provider accepts Medicare or is accepting new patients. Medicare SELECT policies may restrict you to a network for full benefits. Original Medicare generally does not require specialist referrals or prior authorization, but exceptions and coverage requirements exist.
Prescription Drug Coverage
Medicare Advantage
Most plans include Part D prescription drug coverage. If you are enrolled in an HMO or PPO Medicare Advantage plan with drug coverage, you generally cannot add a separate standalone Part D plan.
Medigap
Medigap policies sold today do not include Part D prescription drug coverage and do not pay Part D copays. This is separate from cost-sharing for certain medications covered under Part B, which a Medigap policy may help pay according to its benefits. You can add a standalone Part D plan.
Out-of-Pocket Limits
Medicare Advantage
Medicare Advantage plans have a medical out-of-pocket limit that applies to covered Part A and Part B cost-sharing. The limit varies by plan and year, and some plans have separate in-network and combined in/out-of-network limits. This limit does not combine all premiums, Part D drug spending, and noncovered services into one cap.
Medigap
Most Medigap plans do not have an annual out-of-pocket limit. Plans K and L do have defined limits. Your remaining costs depend on the specific Medigap plan. For example, standard Plan G does not cover the annual Part B deductible, and it should not be confused with high-deductible Plan G or taken to eliminate every possible healthcare expense.
Extra Benefits & Travel
Medicare Advantage
Dental, vision, hearing, fitness, and over-the-counter benefits are plan-dependent, not universal or unlimited. Medicare Advantage covers emergency and urgently needed care outside the local network within the United States. Routine care away from home depends on the plan.
Medigap
Medigap benefits are standardized by plan letter. Some Medigap policies provide limited foreign-travel emergency benefits, but this is not comprehensive international medical coverage. Optional insurer discounts or extra programs are separate from the standardized benefits.
What to Compare: A Cost Checklist
Instead of relying on fixed dollar scenarios, use this checklist to compare the plans available to you. The right choice depends on your specific doctors, prescriptions, healthcare needs, and budget.
- Applicable Part B premium — you generally pay this under either approach.
- Medicare Advantage premium, if any — varies by plan.
- Medigap premium, when applicable — varies by plan letter, insurer, and other factors.
- Separate Part D premium, when applicable — if you have Original Medicare with Medigap or a Medicare Advantage plan without drug coverage.
- Medical deductibles, copayments, and coinsurance — vary by service and plan.
- Prescription deductibles and cost-sharing — vary by plan and medication tier.
- The applicable medical out-of-pocket limit — for Medicare Advantage, varies by plan and year.
- Costs for services the coverage does not pay — such as noncovered services or out-of-network care.
- Any financial assistance or premium reduction relevant to your situation.
Part D has separate out-of-pocket protection for covered drugs. Neither approach is always or almost always cheaper based solely on whether someone is healthy or has chronic conditions. The comparison depends on the specific plans and your individual situation.
Enrollment and Switching Rules
Medigap Open Enrollment Period
The federal six-month Medigap Open Enrollment Period begins the first month you are both 65 or older and enrolled in Part B. During this period, an insurer cannot use your health status to deny a policy it offers for which you are eligible, or charge you more because of your health.
Example: If you are 65 or older and your Part B coverage begins March 1, your six-month Medigap Open Enrollment Period runs from March 1 through August 31.
This does not mean all pre-existing-condition waiting periods are automatically waived. Prior creditable coverage and applicable protections matter. After this period ends, underwriting may apply unless another guaranteed-issue or state protection applies.
Fall and Medicare Advantage Enrollment Periods
- Fall Medicare enrollment (October 15 to December 7): You can join, switch, or drop Medicare Advantage plans and Part D plans.
- Medicare Advantage Open Enrollment (January 1 to March 31): If you are already in a Medicare Advantage plan, you can switch to a different Medicare Advantage plan or return to Original Medicare.
- Qualifying Special Enrollment Periods: Certain life events, such as moving or losing other coverage, may give you a window to change plans.
Medigap applications are not limited to the fall Medicare enrollment period. However, being allowed to leave Medicare Advantage does not automatically mean an insurer must accept a Medigap application.
Trial Rights and Guaranteed-Issue Situations
If you join a Medicare Advantage plan for the first time, you may have a 12-month trial right to return to Original Medicare and buy a Medigap policy. This right does not mean every person in their first year of any Medicare Advantage plan automatically qualifies. Other guaranteed-issue situations exist, such as losing employer or retiree coverage through no fault of your own, or your Medicare Advantage plan leaving your service area.
Florida also provides protections for certain Medicare beneficiaries under 65 and certain people losing group coverage. The federal age-65 window is not the only possible protection. If you are considering switching, coordinate acceptance and effective dates before ending existing coverage.

Florida Medigap Premium Information
Florida Medicare Supplement policies are sold on an issue-age basis. Premiums do not increase simply because the insured gets older, but approved increases can occur for other reasons. This is not an attained-age pricing model, and an issue-age policy is not guaranteed to remain at the same dollar premium forever.

Reader Questions
Can I change from Medicare Advantage to Medigap?▼
You can apply for a Medigap policy at any time, but after your six-month Medigap Open Enrollment Period closes, insurers in Florida can require medical underwriting unless another guaranteed-issue right applies. Fall Medicare enrollment (October 15 to December 7) and Medicare Advantage Open Enrollment (January 1 to March 31) let you change Medicare Advantage plans or return to Original Medicare, but being allowed to leave Medicare Advantage does not automatically mean an insurer must accept your Medigap application.
What if my doctor leaves my Medicare Advantage network?▼
A doctor leaving your plan's network does not automatically guarantee a Special Enrollment Period. Contact the plan and Medicare about continuity of care and whether your circumstances qualify for a Special Enrollment Period.
Do I need Part D with Medigap?▼
Medigap policies sold today do not include Part D prescription drug coverage and do not pay Part D copays. If you have Original Medicare with Medigap, you can add a separate Part D plan. Someone without other creditable prescription coverage should consider Part D even if they currently take few or no medications, because a gap of 63 consecutive days or more without Part D or other creditable drug coverage after the initial enrollment period can result in a late-enrollment penalty. See our Medicare Part D guide for more information.
What are the different Medigap plan types?▼
Medigap plans are standardized by letter (A, B, C, D, F, G, K, L, M, N). The same plan letter generally has the same basic benefits across insurers in Florida, while different letters have different benefits. Eligibility for Plans C and F depends on whether you were first eligible for Medicare before January 1, 2020 — not simply whether you already owned one of those plans.
Can I use Medicare Advantage when traveling?▼
Medicare Advantage covers emergency and urgently needed care outside the local network within the United States. Routine care away from home depends on the plan. Some Medigap policies provide limited foreign-travel emergency benefits, but this is not comprehensive international medical coverage.
How much do Medigap plans cost in The Villages area?▼
Medigap premiums vary by plan letter, insurer, your age at purchase, ZIP code, and tobacco status. Florida uses issue-age pricing, so your age at enrollment helps set your premium. I compare current premiums from the carriers I represent so you can see the full picture before choosing.
