Medigap plan comparison chart (2027)
What each standardized Medigap plan pays in Missouri. Medigap plans are standardized by federal law, so a plan letter covers the same benefits whichever insurer sells it; the price is what differs. “100%” means the plan pays the whole benefit, a lower percentage means it pays that share, “No” means it does not cover it.
| Benefit | Plan A | Plan B | Plan C | Plan D | Plan F | Plan G | Plan K | Plan L | Plan M | Plan N |
|---|---|---|---|---|---|---|---|---|---|---|
| Part A coinsurance and hospital costs, up to 365 days after Medicare benefits are used | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% |

Plans C and F can be bought only by people who were eligible for Medicare before January 1, 2020; people new to Medicare since then can buy the other letters. Plans F and G also come in a high-deductible version that pays after a yearly deductible. * Plan N pays the Part B coinsurance except for a copayment for some office visits and for emergency-room visits that do not lead to an inpatient admission. ** Plans K and L pay 100% of covered services for the rest of the year once you reach their yearly out-of-pocket limit, which CMS sets each year. Massachusetts, Minnesota and Wisconsin standardize Medigap their own way, so this chart does not apply there.

What Medigap does — and doesn't — cover
Think of Medigap as the layer that sits on top of Original Medicare to absorb the costs it leaves you: the deductibles, the 20% coinsurance, the copays that otherwise have no annual ceiling.
The catch that trips people up is that these plans are federally standardized — a Plan G from one insurer covers exactly what a Plan G from another does. So the letter defines the benefits, and price and service are what separate companies. Medigap doesn't include drug coverage, so most people in Liberty, Missouri pair it with a stand-alone Part D plan.
Below we break down what each standardized plan covers and the enrollment rights that matter most in Liberty, Missouri. It's a framework, not a ranking — and we don't quote premiums.

How people get Medicare in Clay County
(MA penetration in Clay County)
MA penetration from CMS enrollment data; Medigap share is an estimate. U.S. average is about 54% Medicare Advantage. These are area-level figures, not plan-specific.

The 2027 numbers, from shared to plan-specific
Start with what's fixed for everyone. The standard Part B premium is $202.90 per month in 2026 (2026 amount; 2027 figure will be posted when CMS releases it), and Part A is premium-free for most people who paid Medicare taxes long enough while working.
On the drug side, Part D has real guardrails for 2027: a deductible capped at $700 and, a hard $2,400 ceiling on your out-of-pocket costs for covered prescriptions — the old coverage gap is gone.
Higher earners pay more for Parts B and D through an income-related adjustment called IRMAA, which for 2026 starts above $109,000 in annual income for an individual and is based on your 2024 tax return. Most people fall below that line and pay the standard amounts. The 2027 brackets will be posted when CMS releases them.
Everything past that is plan-specific: the premiums, copays, and coverage details of an individual Advantage or Medigap plan change from plan to plan and year to year. Rather than quote or rank those, we point you to Medicare's Plan Finder and a licensed agent for your exact numbers.
By the numbers

When you can enroll or make changes
Medicare's enrollment windows are federal — the same nationwide — so the timing below applies wherever you live.
Your first window (IEP). When you're new to Medicare, your Initial Enrollment Period is the 7-month window around your 65th birthday month. Signing up on time helps you avoid late penalties that can follow you for years.
Annual Enrollment Period (AEP). Each fall, from October 15 – December 7, anyone with Medicare can join, switch, or drop a Medicare Advantage or Part D plan. Changes take effect January 1.
Medicare Advantage Open Enrollment. From January 1 – March 31, if you're already in an Advantage plan you get one chance to switch plans or return to Original Medicare.
Special Enrollment Periods can also open after certain life events, like moving or losing other coverage. The interactive calendar further down lays the year out visually.
