Miami Medigap in 2027: the plan letters, the Part B reset, and rate-filing season

MIAMI — As 2027 approaches, Miami-Dade residents who have Medigap coverage — or are thinking about buying it — will see a familiar cycle repeat. Plan letters stay standardized, the Part B deductible resets on Jan. 1, and Florida insurers file their new rates with the state. None of this is a crisis, but the timing matters if you want to shop smart.

Here is what is actually changing for Medigap in Miami for the coming year, and how to make a clear-headed decision.

The plan letters available in Miami

Medigap is federally standardized. That means a Plan G sold in Miami covers the same gaps in Original Medicare as a Plan G sold anywhere else in Florida. What differs between insurers is the price and the customer service — not the benefits inside a given letter.

If you are newly eligible for Medicare today, these are the plan letters you can buy in Florida: A, B, D, G, high-deductible G, K, L, M and N. Plans C and F are only available to people who became eligible for Medicare before Jan. 1, 2020. That eligibility rule is unchanged for 2027.

Because the letters are standardized, the shopping question is not "which plan is best?" but "which letter fits how I use care, and which insurer offers a stable price for that letter in my ZIP code?"

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

Plans G and N are the two letters most people newly eligible in Florida consider, and both are structured around the Part B deductible. With Plan G, you pay the Part B deductible yourself each calendar year, and the plan picks up the rest of the Part B coinsurance. Plan N works similarly, with small copays for some office and emergency visits.

Every Jan. 1, that Part B deductible resets. Medicare publishes the new figure late in the prior year on Medicare.gov. Before you renew or switch, check the 2027 number so you know exactly what you'll pay out of pocket before your Medigap plan kicks in.

Rate-filing season in Florida

Medigap premiums are not set by Medicare. In Florida, insurers file proposed Medigap rates with the state, and those filings drive the renewal notices you receive from your carrier. Rate changes can vary from insurer to insurer even for the same plan letter, which is why two Plan G policies in the same Miami ZIP code can carry very different premiums.

There are three official places to check:

• Medicare.gov's Medigap policy search — enter your ZIP code to see which insurers offer which letters in Miami-Dade.
• The Florida Office of Insurance Regulation — publishes Medigap rate guides and filings.
• Florida SHINE, the state's SHIP program — free, unbiased counseling by phone or in person.

Insurers entering or leaving

Carrier participation in Florida's Medigap market can shift from year to year. We are not listing insurers here because that information changes and should be pulled live from the sources above rather than from an article. The Medicare.gov Medigap search is the most current view of who is actively selling which letters in your ZIP code today.

If you get a notice that your current insurer is discontinuing a plan, do not ignore it — call the number on the letter and also call Florida SHINE to understand your options and any protected rights to switch.

How to decide, in plain steps

1. Confirm the plan letter you have (or want). Remember: the benefits inside that letter are the same at every insurer. 2. Look up the 2027 Part B deductible on Medicare.gov so you know your first-dollar exposure under Plan G or N. 3. Use the Medicare.gov Medigap policy search for your Miami ZIP code to see current insurers and starting premiums. 4. Ask each insurer how they rate their policies in Florida (age-based, issue-age, or community-rated) — this affects how your premium may change over time. 5. Call Florida SHINE if anything is unclear. It's free.

Also worth knowing: Florida does not have a broad annual "open enrollment" for Medigap the way Medicare Advantage does. Outside of your one-time Medigap Open Enrollment Period when you first sign up for Part B at 65, insurers can generally use medical underwriting. That makes timing and paperwork more important than in Advantage shopping.
