Medicare Supplement insurance (also called Medigap) is private coverage that helps pay certain costs not covered by Original Medicare. These costs include deductibles, copayments, and coinsurance that can add up quickly without supplemental coverage.
If you have Original Medicare (Part A and Part B), a Medicare Supplement plan works alongside your existing coverage to reduce or eliminate many out-of-pocket expenses.
At Kentucky Medicare Help, we help residents across Kentucky understand their Medicare Supplement options, compare plans from multiple insurance companies, and choose coverage that fits their healthcare needs and budget.
Original Medicare pays for many healthcare services, but it doesn't cover everything. Depending on the care you receive, you may still owe significant out-of-pocket costs.
The specific benefits depend on which plan letter you choose. Plans are standardized, meaning Plan G from one company covers the same benefits as Plan G from another company. What differs between companies is the monthly premium, available discounts, customer service, and rate history.

Medicare Supplement plans do not replace Original Medicare. They work alongside it.
Here's how the relationship works:
Original Medicare (Part A and Part B) pays its share of approved healthcare costs first.
Your Medicare Supplement plan then helps pay some or all of the remaining costs, depending on your plan letter.
Because Medicare Supplement plans work with any doctor or hospital that accepts Medicare (nationwide), you generally don't need referrals or network restrictions. This is one of the key differences between Medicare Supplement plans and Medicare Advantage plans.
If you want prescription drug coverage, you'll need to enroll in a separate Medicare Part D plan. We can help you compare Part D options based on your medications and preferred pharmacies.
There are several standardized Medicare Supplement plan letters available in Kentucky. The most commonly chosen plans today are Plan G and Plan N, though other options exist depending on your eligibility and enrollment date.
The most comprehensive standardized plan available to those newly eligible for Medicare. Covers nearly everything Original Medicare doesn't, except the annual Part B deductible ($257 in 2025). Plan G is the most popular choice among new Medicare beneficiaries in Kentucky.
A lower-premium alternative to Plan G with some cost sharing at the point of care. You may pay up to $20 for certain office visits and up to $50 for emergency room visits that don't result in admission. Plan N also does not cover Part B excess charges.
Offers the same benefits as standard Plan G, but with a higher annual deductible ($2,870 in 2025) that you must meet before the plan begins paying. Monthly premiums are typically much lower than standard Plan G.
Previously the most comprehensive plan, covering all gaps in Original Medicare including the Part B deductible. Plan F is no longer available to individuals who became newly eligible for Medicare on or after January 1, 2020. If you were eligible before that date, Plan F may still be an option.
While Medicare Supplement plans significantly reduce out-of-pocket costs, there are certain things they don't cover:
You'll need a separate Medicare Part D plan for medication coverage.
Dental, vision, & hearing are generally not covered by Medicare or Supplement plans.
Extended nursing home stays or in-home custodial care are not covered.
If Medicare doesn't cover a service, your Supplement plan won't cover it either.
If you need prescription drug coverage, dental, vision, or hearing benefits, we can help you explore additional coverage options alongside your Medicare Supplement plan.
A common question we hear is: "If Plan G benefits are the same everywhere, why do premiums vary so much?"
The answer is that each insurance company sets its own pricing based on several factors:
Many companies adjust premiums as you get older.
Rates can differ even between neighboring Kentucky counties.
Non-tobacco rates are typically lower
Some carriers offer savings when multiple household members are insured.
Companies may use attained-age, issue-age, or community-rated pricing. Each method affects how your premium changes over time.
The overall health of a company's policyholders affects pricing.
This is why comparing multiple companies is one of the most valuable things you can do when choosing or reviewing a Medicare Supplement plan.
The lowest rate today isn't always the best value over time.
One of the most significant advantages of Medicare Supplement plans is provider freedom.
With a Medicare Supplement plan, you can generally visit any doctor, specialist, or hospital in the United States that accepts Medicare patients. You don't need:
Referrals to see specialists
Prior authorization for most services
To stay within a network
This means if you travel within the U.S., move to a different part of Kentucky, or want to see a specialist in another state, your Medicare Supplement coverage typically goes with you.
This nationwide flexibility is a key reason many beneficiaries prefer Medicare Supplement plans over Medicare Advantage plans, which often require you to use a specific network of providers.
Medicare Supplement plans work alongside Original Medicare to cover out-of-pocket costs and allow you to see any Medicare-accepting provider. Medicare Advantage plans replace Original Medicare with a private plan that often includes networks, copayments, and additional benefits like dental or vision. The right choice depends on your priorities.
No. You cannot have both. Medicare Supplement plans work only with Original Medicare (Parts A and B). If you enroll in a Medicare Advantage plan, your Medicare Supplement plan cannot pay benefits.
Medicare Supplement plans are standardized at the federal level, meaning Plan G in Kentucky covers the same benefits as Plan G in any other state. However, premiums vary by state, county, and insurance company.
In most cases, yes. You can apply to switch companies at any time, though medical underwriting may apply outside of certain guaranteed issue situations. We help Kentucky residents compare options and coordinate the switch.
No. You'll need a separate Medicare Part D plan for prescription drug coverage. We can help you compare Part D options based on your specific medications.
No. There is no additional fee for our Medicare guidance, plan comparisons, or enrollment assistance. Your premium is the same whether you enroll through us or directly with the insurance company.
We'll compare premiums, discounts, and long-term value from multiple insurance companies to help you find the right coverage.
