Medicare Advantage vs. Medigap in Southaven for 2026

If you're turning 65 in Southaven, or helping a parent sort through Medicare mail, you've probably noticed something confusing: people keep talking about two very different ways to get Medicare. One is called Original Medicare with a Medigap policy. The other is Medicare Advantage.

Southaven, Miss. — Two Paths, One Big Decision

They're not small variations of the same thing. They're two separate paths, with different rules for how you see doctors, how you pay, and what happens if you get sick. Understanding the structure — before you look at any specific plan — is the single most useful thing you can do.

Path One: Original Medicare + Medigap (+ usually a Part D drug plan)

Original Medicare is the federal program run directly by the government. It has two pieces:

• Part A covers hospital stays.
• Part B covers doctor visits, outpatient care, and many preventive services.

Original Medicare pays its share, and you're responsible for the rest — deductibles, coinsurance, and so on. There's no yearly cap on what you could owe out of pocket.

That's where Medigap (also called Medicare Supplement Insurance) comes in. Medigap is a separate policy you buy from a private insurance company to help pay the costs Original Medicare doesn't cover. Medigap policies are standardized by letter (Plan G, Plan N, and so on), so a Plan G from one carrier covers the same things as a Plan G from another.

Two important notes:

• Medigap does not include prescription drug coverage. Most people on this path also enroll in a stand-alone Part D drug plan.
• Original Medicare lets you see any doctor or hospital in the U.S. that accepts Medicare — no network. That's a big deal if you split time between Mississippi and another state, or travel to see family.

Path Two: Medicare Advantage (Part C)

Medicare Advantage is different. Instead of getting your coverage from the federal program, you get it from a private insurance company that has been approved by Medicare to bundle your benefits together.

A Medicare Advantage plan typically includes Part A, Part B, and usually Part D drug coverage in one plan. Many plans also add extras like routine dental, vision, or hearing coverage.

The trade-off is structure. Medicare Advantage plans generally use networks of doctors and hospitals — often HMOs or PPOs — and may require referrals or prior authorization for certain services. They also come with a yearly out-of-pocket maximum, which Original Medicare alone does not have.

What's Available Around Southaven

Southaven is in DeSoto County, where plan availability is set at the county level by the Centers for Medicare & Medicaid Services (CMS). That means the specific menu of Medicare Advantage plans, stand-alone Part D drug plans, and Medigap carriers offered to a Southaven resident is the same as anywhere else in DeSoto County — but different from what someone in Memphis or Tupelo sees.

2026 Numbers Worth Knowing

A few program-wide figures for 2026, regardless of which path you take:

• Part D out-of-pocket cap: $2,100. Once your covered drug spending hits that amount, you pay $0 for covered drugs the rest of the year.
• Part D maximum deductible: $615.
• The old "donut hole" coverage gap is gone (as of 2025). Part D now works in three phases.
• The Medicare Prescription Payment Plan lets you spread drug costs into monthly payments across the year, if that helps with cash flow.
• IRMAA — an income-related surcharge on Part B and Part D — begins above $109,000 in income for a single filer in 2026.

Deadlines to Circle

• October 15 – December 7: Medicare Annual Enrollment Period. You can join, switch, or drop a Medicare Advantage or Part D plan.
• January 1 – March 31: Medicare Advantage Open Enrollment. If you're already in a Medicare Advantage plan, you get one chance to switch to a different one or return to Original Medicare.

One rule that trips people up: the best time to buy a Medigap policy is during your six-month Medigap Open Enrollment window, which starts the month you're 65 and enrolled in Part B. During that window, insurers can't turn you down or charge more for health reasons. After it closes, medical underwriting may apply in most states, including Mississippi.

Reader Questions

Can I have both Medigap and Medicare Advantage? No. Medigap only works with Original Medicare. It's illegal for someone to sell you a Medigap policy if you're on a Medicare Advantage plan.

If I pick Medicare Advantage now, can I switch to Medigap later? You can switch back to Original Medicare during the right enrollment window, but buying a Medigap policy later may require answering health questions. Some people find they can't get the Medigap plan they want after their initial window closes.

Do I have to take Part D if I don't take any prescriptions? Not required, but if you go without "creditable" drug coverage for too long, you may owe a late enrollment penalty later — for life. Many people enroll in a low-cost plan just to avoid the penalty.

Where can I get unbiased help in Mississippi? The Mississippi State Health Insurance Assistance Program (SHIP) offers free, one-on-one Medicare counseling. They don't sell anything.

Take your time. The choice between these two paths shapes your care and your costs for years, and it's worth understanding before anyone shows you a specific plan.
