Medicare Supplement Plan G (Medigap Plan G) is a private insurance policy that fills most of the cost-sharing gaps in Original Medicare — the Part A hospital deductible and coinsurance and nearly all Part B cost-sharing — after you pay the annual Part B deductible yourself.
Short answer: Medicare Supplement Plan G covers the Part A hospital deductible, Part A and Part B coinsurance, Part B excess charges, the first three pints of blood, skilled nursing facility coinsurance, and foreign travel emergency care (80%, up to plan limits). It covers everything Original Medicare's gaps except the Part B deductible, which you pay once each year before Plan G pays anything. After that deductible, Plan G pays 100% of Medicare-approved costs for the rest of the year, with no network restrictions — you can see any doctor or hospital that accepts Medicare nationwide.

Plan G covers the Part A deductible and hospital coinsurance, skilled nursing facility coinsurance, Part B coinsurance and copayments, the first three pints of blood, Part B excess charges, and 80% of foreign travel emergency care up to plan limits. That is the full standardized Medigap benefit set minus one item: the Part B deductible.
That one exclusion is the whole design of the plan. You pay the Part B deductible out of pocket each calendar year. Once Medicare has processed enough of your claims to satisfy it, Plan G pays its share of everything else Medicare approves — doctor visits, outpatient surgery, lab work, durable medical equipment — at 100% of the Medicare-approved amount. No copays. No coinsurance. No per-visit charges for the rest of the year.
One everyday example makes this concrete. Ground ambulance transportation to a hospital is covered by Medicare Part B when it is medically necessary. Per Medicare.gov, "After the Part B deductible, you pay 20% of the Medicare-approved amount." With Plan G, that 20% is what your supplement pays instead of you. The same logic applies to outpatient procedures, imaging, and specialist visits.
Part B excess charges deserve special attention in Florida. Some doctors who accept Medicare do not accept Medicare's approved amount as payment in full; they may charge up to 15% more. Original Medicare pays its 80% of the approved amount and you would owe the rest. Plan G covers excess charges in full. In markets with many specialists who bill this way, that single benefit can matter more than any other line in the plan's benefit chart.
The most common comparison we walk through with clients in Lee County is Plan G versus Plan N. Both cover the same core hospital and medical gaps. Three differences separate them.
First, Plan N requires copayments — up to $20 for office visits and up to $50 for emergency room visits that do not result in admission (illustrative of the standardized Plan N design; confirm current cost-sharing with the carrier). Plan G has no copays after the Part B deductible. Second, Plan N does not cover Part B excess charges. Plan G does. Third, Plan N premiums are typically lower than Plan G premiums from the same carrier, because you are accepting more cost-sharing.
Which wins depends on how often you see doctors and whether your local providers bill excess charges. A client who visits specialists monthly in Fort Myers may find Plan G's flat coverage simpler and more predictable. A healthy client with few visits may prefer Plan N's lower premium and pay the occasional copay. The carrier sets rates and approves or declines the application either way, so the honest answer is: run both quotes and compare them against your actual usage.
| Feature | Plan G | Plan N | Medicare Advantage |
|---|---|---|---|
| Part B excess charges | Covered | Not covered | Not applicable (network plans) |
| Doctor/hospital choice | Any provider accepting Medicare nationwide | Any provider accepting Medicare nationwide | Plan network; referrals may apply |
| Office visit cost-sharing | None after Part B deductible | Copay per visit | Copay per visit, varies by plan |
| Part B deductible | You pay it | You pay it | Handled within plan design |
| Foreign travel emergency | 80% up to plan limits | 80% up to plan limits | Varies by plan |
Takeaway: Plan G trades a higher premium for the fewest out-of-pocket surprises; Plan N trades copays and excess-charge exposure for a lower premium; Medicare Advantage trades provider freedom for plan-managed networks.
Plan G premiums are set by each carrier and vary with your age when you enroll, your zip code, tobacco use, and gender. Two 70-year-olds in different Florida counties can receive meaningfully different quotes for the identical standardized benefit, because pricing method (attained-age vs. issue-age), carrier claims experience, and county rating factors all differ.
What we can show from our own records is the pattern, not a promise. In our plan-comparison work with Lee County clients, the relative pattern we see is consistent: clients on Plan G report the lowest year-to-year variation in what they pay after premiums, because there are no copays and no excess-charge exposure; Plan N clients pay somewhat more in moderate-usage years; Medicare Advantage out-of-pocket costs depend heavily on whether care stays in network. The exact figures behind this comparison come from the client's own plan records and vary person to person — treat the chart as a picture of relative patterns, not a quote.
When you request quotes, ask each carrier two questions: Is this an attained-age or issue-age rating? And does the premium increase with age bands or only with general rate adjustments? The answers shape what your premium looks like ten years from now, not just next January.
Your Medigap Open Enrollment Period runs the six months beginning the month you are 65 or older and enrolled in Medicare Part B. During that window, carriers generally must accept your application and does not price it based on health conditions. Outside that window, the carrier sets rates and approves or declines the application, and medical underwriting may apply.
Florida adds one protection worth knowing: the state has guaranteed-issue windows tied to certain events, such as employer coverage ending or a Medicare Advantage plan leaving your service area. If you are in one of those situations, ask a licensed agent to confirm which window applies to you before you apply, because timing determines whether underwriting is involved.
Another timing note: you can switch from Plan G to Plan N or to a Medicare Advantage plan at various points, but switching back into Plan G later usually requires underwriting unless a guaranteed-issue window applies. Direction matters. Clients often tell us they wish they had understood that asymmetry before their first switch.
Plan G tends to fit people who want predictability: those who see several specialists, travel between Florida and another state for part of the year, or simply prefer a known premium over variable cost-sharing. Snowbirds value the nationwide provider access — any doctor or hospital that accepts Medicare, no networks, no referrals. Seasonal residents of Cape Coral and Fort Myers tell us this is often the deciding factor.
Plan G also fits people who want protection against excess charges. In counties where a meaningful share of specialists balance-bill above the Medicare approved amount, the excess-charge benefit quietly does real work every year.
It is a weaker fit for someone with very low healthcare usage who is comfortable with copays and wants the lowest premium available. For that profile, Plan N or a Medicare Advantage plan may align better. There is no single right answer — there is the right answer for your usage, your providers, and your budget.
Our agency has served Lee County for years, and the Cape Coral and Fort Myers service mix shapes what we see: a large seasonal-resident population, many clients managing multiple specialists, and steady attendance at our local Medicare seminars where plan-comparison questions come up year after year. That local pattern is why we emphasize excess charges and travel coverage when we review Plan G with clients here.

Because Medigap plans are standardized, Plan G from Carrier A covers exactly what Plan G from Carrier B covers. The benefit chart is identical. What differs is price, rating method, rate-increase history, and service. So the comparison work is really about the carriers, not the benefits.
Check three things for each quote. Rating method: issue-age pricing generally holds steadier over time than attained-age pricing. Rate-increase history: ask how often the carrier has raised Medigap rates in recent years and by how much — a low starting premium with frequent steep increases can cost more over a decade. Household discount and underwriting: some carriers offer multi-policy or household discounts, and each carrier's underwriting rules differ outside guaranteed-issue windows.
Our team compares these factors across carriers for clients throughout Lee County as a routine part of a plan review. You can also start with our broader guide to Medicare Supplement plans in Florida for the full picture of lettered plans and how they fit together.
Two questions come up at nearly every seminar we hold in Cape Coral and Fort Myers. First: "Does Plan G cover dental, vision, or prescriptions?" It does not — Medigap plans supplement Original Medicare's medical cost-sharing only. Prescription drug coverage requires a separate Part D plan, and dental and vision are typically handled through standalone policies or a Medicare Advantage plan. Second: "Do I need Plan G if I have retiree coverage?" It depends on how your retiree plan coordinates with Medicare, and that coordination is plan-specific. Bring the summary of benefits to an agent before assuming you need a supplement at all.
A third pattern we see: clients who enrolled in a Medicare Advantage plan years ago and now want to return to Original Medicare with a supplement. This is possible, but the timing and underwriting rules are specific. Review the options with a licensed agent before you disenroll, because the window you use determines whether the carrier can decline the application.
For related reading, see our comparison of Medicare Advantage plans in Southwest Florida and our breakdown of Medigap Plan N benefits and costs.
No. Plan G covers every standardized Medigap benefit except the annual Part B deductible, which you pay out of pocket each calendar year before Plan G's Part B coverage begins. Once the deductible is satisfied, Plan G pays 100% of the Medicare-approved amount for covered Part B services for the rest of the year. The Part B deductible amount is set by Medicare and can change annually, so confirm the current figure at Medicare.gov.
Neither plan is universally better; they trade cost for cost-sharing. Plan G has no copays after the Part B deductible and covers Part B excess charges, but its premium is typically higher. Plan N has a lower premium but charges office and ER copays and does not cover excess charges. The better choice depends on your doctor-visit frequency, your local providers' billing practices, and your budget.
You can apply, but acceptance is not automatic. Outside guaranteed-issue situations, the carrier sets rates and approves or declines the application, and medical underwriting may apply. Certain events — such as your Medicare Advantage plan leaving your service area — may open a guaranteed-issue window in Florida. Confirm your specific situation with a licensed agent before disenrolling from your current plan.
Plan G works with any doctor or hospital that accepts Medicare, anywhere in the country, with no networks or referrals. That is a property of how Medigap supplements Original Medicare, not of a particular carrier. For snowbirds and seasonal residents of Southwest Florida, this nationwide access is one of the most frequently cited reasons for choosing Plan G over network-based coverage.
Your Medigap Open Enrollment Period — the six months starting the month you turn 65 and enroll in Part B — is generally the strongest position, because carriers generally must accept your application regardless of health. Outside that window, underwriting applies unless a guaranteed-issue situation applies. If you are approaching 65 or losing employer coverage, talk to a licensed agent a few months ahead so you can time the application well.
