This guide is designed to help you compare Medicare Supplement programs in a clear, side-by-side format, so you can better understand how standardized options work and how they may align with your budget and healthcare priorities.
What this comparison is designed to do
This comparison is designed for ongoing reference. In one place, you can:
- Compare standardized Medicare Supplement (Medigap) programs by plan letter

- Review general monthly cost patterns associated with different plan types
- Evaluate which approaches may support more predictable healthcare spending
Medicare Basics: Understanding where Supplement Programs Fit In
Original Medicare includes Part A (hospital services) and Part B (medical services). While Medicare pays a large portion of approved amounts, individuals remain responsible for certain costs.
Medicare Supplement programs, often referred to as Medigap, are offered by private companies and are designed to work alongside Original Medicare by helping with some of those remaining expenses.
These programs do not replace Medicare. Instead, they work alongside it.

Notes to take into consideration when you compare Medicare Supplement programs:
- Plans C and F aren’t available to people who are new to Medicare on or after Jan. 1, 2020.
- Plans F and G may also be offered with a high-deductible option in some states; the 2025 high-deductible amount is $2,870 before the plan starts helping with those Medicare-approved costs.
- For Plan N, Part B coinsurance is included, but there are set amounts for some office visits and certain ER visits.
- For Plans K and L, once you meet the plan’s out-of-pocket yearly limit and your Part B deductible ($257 in 2025), the plan supports 100% of Medicare-approved services for the rest of the calendar year.
- Amounts may change each year. Confirm current figures through official Medicare resources.

How To Compare Medicare Supplement Programs With Your Budget In Mind
When reviewing options, it can help to step back and consider how each approach fits your overall financial picture:
- Predictability vs. flexibility
Some programs support more predictable healthcare spending but may come with higher monthly costs.
- Shared responsibility
Lower-cost options may involve more personal responsibility when care is received.
- Lifestyle considerations
Travel habits, frequency of care, and long-term planning all play a role in determining fit.
There is no single right answer. The goal is alignment between your expectations, your budget and how each program functions.

Frequently Asked Questions
What makes Medicare Supplement programs standardized?
Medicare Supplement programs are standardized at the federal level, which means each plan letter includes the same set of features regardless of the company offering it. This standardization allows for clearer comparison based on plan letter rather than plan design.
Why do plans with the same letter still have different costs?
While plan features are standardized, companies may set different pricing based on factors such as location, age, and pricing approach. As a result, monthly costs can vary even when the plan letter is the same.
Are Medicare Supplement programs the same as Medicare Advantage?
No. Medicare Supplement programs are designed to work alongside Original Medicare, while Medicare Advantage is an alternative way of receiving Medicare services. The two approaches function differently and are not interchangeable.
Why do some plans include out-of-pocket limits while others do not?
Only certain Medicare Supplement programs include annual out-of-pocket limits. These limits reflect how those specific plans are structured and can be a consideration for individuals planning around defined spending thresholds.
