Why your Medigap bill in St. Lucie County may shift in 2026

PORT ST. LUCIE, Fla. — If you have a Medigap policy in St. Lucie County, or you are shopping for one, a few moving pieces line up every winter: the standardized plan letters you are allowed 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 Florida regulators. None of it is dramatic on its own, but together they shape what your coverage looks like heading into 2026.

Here is a plain-English snapshot for Port St. Lucie readers.

What plan letters you can actually buy

Medigap policies are standardized by letter, which means a Plan G from one insurer covers the same gaps as a Plan G from another. What differs is the price, the customer service and the insurer's rate history.

The catch newer enrollees keep bumping into: Plans C and F are only sold to people who were eligible for Medicare before January 1, 2020. If you turned 65 after that date, or you are just now aging in, those two letters are not options for you. The letters open to newly eligible people today are A, B, D, G, G-HD, K, L, M and N.

The table below lists every insurer selling Medigap in Florida and the letters each one offers. You will see familiar names like AARP - UnitedHealthcare Insurance Company, Florida Blue, Humana (Humana Insurance Company) and Mutual of Omaha (United World Life Insurance Company), alongside smaller carriers such as Everence Association Inc. and WoodmenLife.

The Part B deductible reset — why it matters for Plans G and N

Plan G and Plan N are the two letters most new enrollees look at, and both are structured the same way at the front end: you pay the Part B deductible first, and the policy picks up from there (Plan N also leaves some office and ER copays with you).

That Part B deductible is a federal number that resets every January 1. When it goes up, the amount you pay out of pocket before your Plan G or N kicks in goes up with it. When it holds steady, so does your share. We are not printing a figure here because it changes year to year — you can confirm the 2026 amount on medicare.gov under "Medicare costs."

The high-deductible version of Plan G (G-HD) works differently: you pay a much larger deductible before the plan pays, in exchange for a lower monthly premium. Several Florida insurers offer it, and you can see which ones in the table below.

Rate-adjustment season in Florida

Medigap monthly premiums are not set by Medicare or by CMS. In Florida, insurers file proposed rate changes with the state's Office of Insurance Regulation, and those filings are public. Rates can change for a number of reasons — the age of the policyholder pool, medical inflation, claims experience — and different insurers can move in different directions in the same year.

Two practical points for Port St. Lucie readers:

• Your renewal letter is the document that matters. It will tell you your new premium and when it takes effect.
• Same letter, different price. Because the benefits are standardized, if your Plan G premium jumps, it is worth getting quotes from other insurers offering Plan G in Florida (the table below shows who does).

If you want to see filings directly, the Florida Office of Insurance Regulation posts them on its website, and Florida's SHINE program (the state's SHIP) can help you read them.

Insurers entering or leaving

Medigap carriers do come and go from the Florida market, but changes are usually quieter than in Medicare Advantage. We are not naming any entries or exits here because we do not have confirmed 2026 changes to report. What you can do:

• Look up your current policy on the Medicare.gov Medigap policy search to confirm it is still being offered.
• If you get a non-renewal notice, read it carefully — it will spell out your guaranteed-issue rights and any deadlines to switch without medical underwriting.

Switching plans: the Florida rule you should know

Florida does not have a year-round "birthday rule" or open-switching window like some other states. Outside your one-time six-month Medigap Open Enrollment Period (which starts when you are 65 and enrolled in Part B), insurers can generally use medical underwriting to decide whether to accept you and at what price.

There are federal guaranteed-issue situations — for example, if a Medicare Advantage plan leaves your area or you move out of its service area — but they are narrow. Before you drop or switch a Medigap policy, it is worth a free call to SHINE (Florida's SHIP) at 1-800-963-5337 to make sure you will qualify for the new one.
