Choosing a Medigap Policy is a good starting point. However, before you can choose, it's best to understand Medicare's costs fully.

What Costs Do Medigap Plans Cover?

Medicare Supplement plans help cover out-of-pocket costs for Medicare Part A and B, including deductibles, coinsurance, and excess charges. Plans F and G offer the most comprehensive coverage, while Plan N offers a lower-cost option with some copays.

How Medigap Plans Help with Overall Costs

Medigap plans help cover the gaps in Medicare coverage, which can be significant when considering the costs associated with hospital stays, outpatient care, and other services. Here’s a quick breakdown of the out-of-pocket costs in Original Medicare that Medigap plans can help you manage:

Hospital Deductible and Coinsurance : The Part A deductible of per benefit period and daily coinsurance costs for extended hospital stays can quickly add up. Medigap Plan F, G, and N cover this cost.
Skilled Nursing Facility Coinsurance : After the first 20 days of care, Medicare requires you to pay a daily amount ( in \) for skilled nursing facility care. Medigap plans help cover this expense.
Part B Deductible and Coinsurance : Outpatient care can also be expensive, especially with the 20% coinsurance required after you meet your Part B deductible (\ in \). Medigap plans can significantly reduce these out-of-pocket expenses.
Excess Charges : For those who see providers that do not accept Medicare assignment, excess charges can be an unexpected cost. Medigap plans that cover excess charges protect you from these fees.

Additional Benefits and Considerations

While Medicare Supplement plans offer significant financial protection by covering many out-of-pocket expenses associated with Medicare Part A and Part B, they do not cover everything. For instance, Medigap plans do not cover:

Prescription Drugs : You must enroll in a Medicare Part D plan for prescription drug coverage.
Long-Term Care : Medigap does not cover long-term care , such as extended stays in nursing homes beyond what Medicare covers.
Dental, Vision, and Hearing : Routine dental care, vision care, and hearing aids are also not covered by Medigap plans. You may need to seek separate dental and vision insurance or pay out of pocket for these services.

Medigap plans are standardized across all states (except for Massachusetts, Minnesota, and Wisconsin, which have different plans). This means that regardless of the insurance company, the benefits of each plan type (e.g., Plan A, Plan G) are the same, making it easier to compare costs.

How Much Do Medigap Plans Cost?

Medicare Supplement plans are standardized, but policy prices are set by the individual insurance companies selling them. Companies set their monthly premium rates in one of three ways:

Attained-age-rated: Monthly premiums are based on age at the time of purchase. Premiums increase as you age.
Community-rated: Monthly premiums are the same for everyone in the policy, regardless of age.
Issue or entry age-rated: Monthly premiums are lower if you purchase the policy at a younger age. Rates do not increase with age.

The attained-age rating method is the most common method used.

Which Medigap Plan Is Best?

Medicare Supplement Plans F, G, and N are the most popular plans, but are they the best? Not necessarily. When considering which Medicare Supplement Plan is best for you, you must identify your current and future healthcare needs. This is the only way to determine if a particular supplement is better for you.

Plan F

Medigap Plan F offers the most comprehensive coverage allowed by Medicare. It covers all deductibles, coinsurance, and copayments in Original Medicare. This plan is only available to individuals who qualified for Medicare before January 1, 2020.

Plan G

If you want comprehensive coverage but don't qualify for Plan F, then Plan G is what you want. Plan G covers all Original Medicare costs except the Part B deductible. And, in most cases, it's more affordable than Plan F when you factor in the deductible.

Plan N

If you are a healthy individual, Plan N might offer the best balance of coverage vs. cost. The reason Plan N works so well for healthy people is that they don't use a lot of medical services. As a result, the monthly premiums are often 20% to 30% lower than Plan G. Even though this plan does not cover Part B excess charges, you pay a small copay to see your doctor and use the emergency room.

FAQs About How to Compare Medigap plans

What Medigap plan is the most popular?

Historically, Plan F held the top spot, but it's no longer an option for those new to Medicare after January 1, 2020. For this reason, Plan G and Plan N have taken the lead. Plan G covers everything Plan F did except for the Part B deductible.

Plan N has also gained traction because its premiums are generally lower than Plans F and G, even though it comes with copays for doctor visits and some emergency room visits. Popularity doesn't equal best for you, though. Choosing a plan is all about weighing your own needs and budget.

What is the downside to Medigap plans?

While Medicare Supplement Insurance plans help manage out-of-pocket expenses, it comes with monthly premiums. It also doesn't cover every healthcare need – you'll still need separate plans for dental, vision, hearing, and long-term care.

Finally, it can get a bit pricey if you develop health issues down the road, especially with attained-age-rated plans.

What is the average cost of a Medigap plan?

The average cost of a Medigap plan varies widely. Factors that affect the price tag include the specific plan, your age, gender, health status, location, tobacco use (if any), and even whether you’re married or single.

To understand Medigap plan costs, get quotes from various insurance companies, like Cigna, Humana, or AARP through United Healthcare. These are companies offering nationwide Medigap plans. UseMedicare.gov to check if a specific insurance company sells Medigap plans in your state.

What is the difference between Medigap plans?

Medigap plans differ primarily in what they cover and how much they cost. Some, such as Plan G, offer more comprehensive coverage and, therefore, come with higher premiums.

Plans with lower premiums typically require more out-of-pocket costs for specific services, like Plan N. When you compare Medigap plans, you should weigh the coverage you desire against your financial capacity.
