Before You Renew Medigap in Kansas City for 2027

Kansas City, Mo. — If you have a Medigap policy in Kansas City, or you are thinking about buying one for 2027, a handful of moving parts are worth watching this season: which standardized plan letters you are eligible to buy, the yearly reset of the Part B deductible that Plans G and N are built around, and the rate filings insurers submit to the Missouri Department of Commerce and Insurance. Kansas City is in Jackson County, and Medigap policies in Missouri follow the same federal standardization rules that apply statewide.

Here is a plain-English snapshot of what is changing — and what is not — for the coming year.

The plan letters you can buy in 2027

Medigap plans are standardized by the federal government and identified by letter. In Missouri, the letters available to someone newly eligible for Medicare today are A, B, D, G, G-HD (a high-deductible version of Plan G), K, L, M and N.

Plans C and F are still sold, but only to people who became eligible for Medicare before Jan. 1, 2020. That rule does not change for 2027. If you were eligible before that date and never enrolled in a C or F plan, you may still be able to buy one; if you became eligible after, those two letters are off the menu for you.

Because the letters are standardized, a Plan G at one company covers the same medical benefits as a Plan G at another. The differences you actually shop on are price, customer service, and how the insurer handles rate increases over time.

The Part B deductible reset that Plans G and N are built around

Plans G and N — the two most commonly chosen letters for new enrollees — are designed to kick in after you pay the Part B deductible. That deductible resets every January to a new amount set by the Centers for Medicare & Medicaid Services (CMS).

For 2027, CMS will announce the new Part B deductible before the year begins. Whatever the figure is, that is what you pay out of pocket for Part B services before your Plan G or Plan N starts paying its share. The high-deductible Plan G (Plan G-HD) works similarly but has its own, much larger, separate deductible before benefits begin.

For the current-year figure, check Medicare.gov's "Medicare costs at a glance" page or call 1-800-MEDICARE.

Rate-adjustment season: how Missouri handles it

Unlike Medicare Advantage and Part D, Medigap premiums are not set on the federal AEP calendar. Insurers file proposed rate changes with the Missouri Department of Commerce and Insurance throughout the year, and changes typically take effect on a policyholder's renewal date rather than every Jan. 1.

That means two neighbors on the same plan letter, at the same insurer, can see rate changes hit in different months. If you get a renewal notice with a higher premium, that is the rate-adjustment cycle at work — not a change to your benefits, which are locked in by the plan letter.

To see what has been filed in Missouri, the state insurance department publishes a Medigap rate guide, and Medicare.gov's Medigap policy search lets you compare current premiums by ZIP code side by side.

Insurers entering or leaving Missouri

Medicare.gov's Medigap policy search is the authoritative, up-to-date list of insurers licensed to sell each plan letter in your ZIP code. Insurer participation can shift from year to year, so before you assume your current company is still writing new business — or before you shop a new one — check the search tool for your Kansas City ZIP.

If your current insurer is not accepting new applications, your existing policy generally continues; the change usually affects only new buyers.

What to do before renewing or switching

A few practical steps for Kansas City readers:

• Read the renewal notice from your current insurer. Note the new premium and the effective date.
• Compare the same plan letter across insurers on Medicare.gov's Medigap policy search using your ZIP.
• Remember that switching Medigap plans outside your initial open enrollment window can involve medical underwriting in Missouri, which may affect whether you are accepted or what you pay.
• If you are new to Medicare, your six-month Medigap Open Enrollment Period — starting the month your Part B begins — is the strongest window for guaranteed acceptance.
