Medigap Plan Letters for Carmel Retirees 2027

CARMEL, Ind. — If you're new to Medicare or thinking ahead to 2027, you've probably heard about "Medigap" plans and noticed they come with letters — Plan A, Plan G, Plan N, and others. The letters can feel confusing at first, but they exist to make shopping easier, not harder.

Making Sense of Medigap in Carmel

Carmel is in Hamilton County, where retirees have the same Medigap options as anywhere else in Indiana. That's because Medigap plans are standardized by the federal government, so the letter tells you exactly what the plan covers, no matter which insurance company sells it.

Here's a plain-English guide to how the letters work and how to think through your choice.

What Medigap Actually Does

Medigap — also called Medicare Supplement Insurance — is a private policy that works alongside Original Medicare (Part A and Part B). It helps pay some of the out-of-pocket costs Original Medicare leaves behind, like coinsurance, copayments, and some deductibles.

A few important things to know:

• Medigap only works with Original Medicare. You can't pair it with a Medicare Advantage plan.
• It doesn't include prescription drug coverage. For that, you'd add a separate Part D plan.
• You pay a monthly premium to the insurance company on top of your Part B premium.

How the Standardized Letters Work

In most states, including Indiana, Medigap plans are sold using ten standardized letters: A, B, C, D, F, G, K, L, M, and N. (Plans C and F are only available to people who became eligible for Medicare before January 1, 2020.)

Because the plans are standardized, Plan G from one company covers the exact same core benefits as Plan G from another company. The differences between carriers usually come down to price, customer service, and extras like discount programs.

The benefits covered across the letters can include:

• Part A hospital coinsurance and hospital costs after Medicare's benefits run out
• Part B coinsurance or copayments
• The first three pints of blood
• Skilled nursing facility coinsurance
• Part A and Part B deductibles (depending on the letter)
• Foreign travel emergency care (on some letters)

Plans K and L work a little differently — they cover a percentage of certain costs and include a yearly out-of-pocket limit.

How to Decide Which Letter Fits

There's no single "right" plan for everyone. The best fit depends on your health, your budget, and how you like to handle medical bills. A few questions to ask yourself:

How much predictability do you want? Plans that cover more benefits usually cost more each month but leave you with fewer surprise bills. Plans that cover less have lower premiums but more out-of-pocket costs when you use care.

Do you travel outside the U.S.? Some letters include foreign travel emergency coverage; others don't.

When did you become eligible for Medicare? If it was on or after January 1, 2020, Plans C and F aren't available to you. Plan G is often compared to Plan F for newer enrollees.

Are you inside your Medigap Open Enrollment Period? This is the six-month window that starts the month you're 65 or older and enrolled in Part B. During this window, insurers can't turn you down or charge you more because of health issues. Outside this window, medical underwriting usually applies in Indiana.

Where Medigap Fits with the Rest of Medicare

Medigap is only one piece of the puzzle. Here's how it fits with other rules worth knowing for 2027:

• Part D drug coverage has an out-of-pocket cap of $2,100 in 2026 and $2,400 in 2027. The maximum deductible is $615 in 2026 and $700 in 2027. The old "donut hole" coverage gap was eliminated in 2025, so drug coverage now works in three phases.
• The Medicare Prescription Payment Plan lets you spread your yearly drug costs across monthly payments if you choose.
• IRMAA surcharges — extra amounts added to Part B and Part D premiums for higher earners — start above $109,000 in income for single filers in 2026.
• The Annual Enrollment Period runs October 15 – December 7 each year, and the Medicare Advantage Open Enrollment Period runs January 1 – March 31.

Keep in mind: Medigap enrollment doesn't follow the same fall window as Part D or Medicare Advantage. You can apply for a Medigap policy at other times, but outside your initial six-month Medigap Open Enrollment Period, acceptance isn't guaranteed in Indiana.
