Switching Medigap in Mauldin? Know the Fine Print First

Switching Medigap in Mauldin? Know the Fine Print First — plain-language Medicare information for Mauldin, South Carolina.

MAULDIN, S.C. — If you have a Medicare Supplement (Medigap) policy and you're wondering whether you can move to a different one, the answer is often "yes, but it depends." Unlike Medicare Advantage and Part D — which have set enrollment windows every fall — Medigap runs on a different clock. Your ability to switch, and whether an insurer can ask about your health first, comes down to a mix of federal rules and, in some states, extra protections your neighbors in other states may not have.

Here in Mauldin, that means it pays to slow down and read the fine print before you drop a policy you already have.

How Medigap switching actually works

Medigap is different from Medicare Advantage. There is no annual window every fall when everyone can freely change Medigap plans. Instead, federal law gives you one strong window — your six-month Medigap Open Enrollment Period, which starts when you're 65 or older and enrolled in Part B. During that window, insurers must sell you any Medigap policy they offer at their best available rate, no health questions asked.

After that window closes, the rules change. In most states, if you apply for a different Medigap policy, the insurer can use medical underwriting — asking about your health history and deciding whether to accept you, and at what price. You could be approved, charged more, or turned down.

That's why "Can I switch?" and "Will I be accepted if I try?" are two different questions.

Federal guaranteed-issue rights

Federal law spells out certain situations where insurers must sell you a Medigap policy without underwriting, even after your open enrollment window has closed. These are called guaranteed-issue rights (sometimes called "Medigap protections"). They generally apply when you lose coverage through no fault of your own or when a plan misleads you. Common examples include:

• Your Medicare Advantage plan leaves Medicare or stops serving your area.
• You move out of your plan's service area.
• Your employer or union coverage that supplemented Medicare ends.
• You joined a Medicare Advantage plan when you first became eligible and want to switch back to Original Medicare within the first 12 months (the "trial right").

There are strict timelines — often 63 days — to use a guaranteed-issue right, so acting quickly matters. You can read the full list at Medicare.gov's Medigap section, or call 1-800-MEDICARE.

State rules that can help you switch

Some states go beyond the federal rules and give residents extra chances to change Medigap policies without underwriting. You may have heard of these:

• Birthday rule: A window around your birthday each year to switch to an equal or lesser Medigap plan.
• Anniversary rule: A window tied to your policy's anniversary date.
• Continuous or year-round open enrollment: A handful of states allow Medigap changes at any time with limited or no underwriting.

Whether South Carolina offers any of these extra protections is something to confirm directly — rules change, and details like which plans are eligible and how long the window lasts vary a lot from state to state. Before you assume you have a right you don't, call the South Carolina SHIP (called SHIP or SHIIP depending on your state) or the South Carolina Department of Insurance. Both can tell you, in plain language, what applies to you today.

How this fits with your other Medicare coverage

Mauldin is in Greenville County, where beneficiaries have a range of Medicare Advantage and stand-alone Part D drug plan choices during the Annual Enrollment Period (Oct. 15 – Dec. 7) and the Medicare Advantage Open Enrollment Period (Jan. 1 – March 31). Those windows apply to Advantage and Part D — not Medigap.

Keep in mind a few 2026 program-level facts as you plan:

• Part D has an annual out-of-pocket cap of $2,100 in 2026.
• The Part D maximum deductible is $615.
• The old coverage gap ("donut hole") was eliminated in 2025; Part D now has three phases.
• The Medicare Prescription Payment Plan lets you spread drug costs across the year in monthly amounts.
• IRMAA income-based surcharges start above $109,000 for a single filer in 2026.

None of these change Medigap directly, but they affect the total picture of what you'll pay.

Mistakes to avoid before you switch

A few small missteps can turn a routine switch into a costly one:

1. Don't cancel your current policy first. Wait until the new insurer has approved you and the new policy is active. Most policies come with a 30-day "free look" period so you can compare side by side. 2. Don't assume all Medigap plans of the same letter cost the same. Benefits are standardized by letter, but premiums are not. 3. Don't ignore the 63-day clock when you have a guaranteed-issue right. 4. Don't rely on hearsay about state rules. Get it in writing from an official source before you apply.
