Medigap in Shreveport: what the lettered plans really cover

SHREVEPORT, La. — If you have Original Medicare and you've ever opened a hospital bill wondering what that 20% coinsurance actually adds up to, you've bumped into the reason Medicare Supplement insurance — better known as Medigap — exists. Medigap is a private policy that helps pay some of the out-of-pocket costs Original Medicare leaves behind. It doesn't replace Medicare. It works alongside it.

Making sense of Medicare Supplement insurance in Shreveport

For readers here in Shreveport, and across Caddo Parish, understanding how Medigap is built can make the difference between guessing and choosing with confidence.

What Medigap actually does

Medigap policies help pay costs that Original Medicare (Part A and Part B) doesn't fully cover. That can include:

• Part A hospital coinsurance and extra days after Medicare's coverage runs out
• Part B coinsurance or copayments
• The first three pints of blood each year
• Part A hospice care coinsurance
• Skilled nursing facility coinsurance
• Part A and (with some plans) Part B deductibles
• Limited foreign travel emergency care (with some plans)

Medigap only works with Original Medicare. If you're enrolled in a Medicare Advantage plan, you can't also use a Medigap policy to cover Advantage cost-sharing.

The lettered plans — and why they're standardized

Here's the part that trips a lot of people up: Medigap plans are labeled with letters — A, B, C, D, F, G, K, L, M, and N. The letters aren't rankings. They're standardized benefit packages set by federal rules, so a Plan G from one company covers the same core benefits as a Plan G from another company.

What can differ between insurers offering the same letter:

• The monthly premium
• Customer service and billing
• Optional extras some carriers bundle in
• How premiums may change as you age

Two important notes from Medicare.gov:

• Plans C and F are only available to people who became eligible for Medicare before January 1, 2020. If you turned 65 after that date, those two aren't options for you.
• Plans K and L have yearly out-of-pocket limits, after which the plan pays 100% of covered services for the rest of the year.
• Plan N typically has small copays for some office and emergency room visits.

Because the benefits inside each letter are fixed by law, comparing Medigap really comes down to comparing companies and prices for the same letter.

Medigap doesn't cover drugs

This surprises a lot of Shreveport readers: Medigap policies sold today don't include prescription drug coverage. For medications, you'd add a stand-alone Medicare Part D drug plan.

A few 2026 Part D facts worth keeping in mind:

• The Part D out-of-pocket cap is $2,100 in 2026.
• The Part D maximum deductible is $615.
• The old "donut hole" coverage gap was eliminated in 2025 — Part D now has three phases.
• The Medicare Prescription Payment Plan lets you spread drug costs out in monthly payments across the year instead of paying big amounts at the pharmacy counter.

Your best window to buy Medigap

Timing matters more with Medigap than almost anywhere else in Medicare. Your Medigap Open Enrollment Period is a one-time, six-month window that starts the month you're 65 or older and enrolled in Part B. During that window, insurers can't turn you down or charge you more based on health.

Outside that window, in most states, insurers can use medical underwriting — meaning your health history can affect whether you're accepted and what you pay. Louisiana follows federal rules on this, so missing the initial window can genuinely limit your choices later.

Note that the Medigap Open Enrollment window is different from Medicare's Annual Enrollment Period (October 15 – December 7) and the Medicare Advantage Open Enrollment Period (January 1 – March 31). Those are for Advantage and Part D changes, not Medigap.

A quick Shreveport snapshot

Medicare plan options in Louisiana are set at the county — here, parish — level. Shreveport sits in Caddo Parish, where residents choose between staying with Original Medicare (often paired with a Medigap policy and a Part D drug plan) or enrolling in a Medicare Advantage plan. Which path fits depends on your doctors, your prescriptions, your travel habits, and your budget — not a one-size answer.
