3.2 Florida Medicare Supplement (Medigap) Regulations
Key Takeaways
Medigap open enrollment is a 6-month window that starts the first month you are both age 65 and enrolled in Medicare Part B.
Florida uniquely extends a 6-month Medigap open enrollment to under-65 disabled beneficiaries, plus a fresh window at age 65.
Guaranteed-issue rights are triggered by specific events and generally must be exercised within 63 days.
Medigap plans are federally standardized A through N; Plans C and F are closed to anyone newly Medicare-eligible on or after January 1, 2020.
Medigap carries a 30-day free look, and producers must deliver an Outline of Coverage and the official Buyer's Guide.
Medigap Open Enrollment
A Medicare Supplement (Medigap) policy fills gaps in Original Medicare (Parts A and B) such as deductibles and coinsurance. The single most-tested fact is the 6-month open enrollment period (OEP).
When the 6 months starts
The OEP begins on the first day of the month in which the beneficiary is BOTH:
- age 65 or older, AND
- enrolled in Medicare Part B
Both conditions must be met. If someone turns 65 in March but delays Part B until July, the window opens in July. During the OEP the beneficiary has:
| Protection | Effect |
|---|---|
| Guaranteed issue | Any participating insurer must sell, regardless of health |
| No medical underwriting | No health questions used to decline |
| No pre-existing waiting period | Conditions covered from day one (subject to crowd-out by prior creditable coverage rules) |
| Standard rates | Cannot surcharge for health |
Exam trap: the window is tied to Part B, not Part A. Someone with Part A only has not started the clock.
Florida's Under-65 Disability Protection
Federal law does not require insurers to sell Medigap to people on Medicare due to disability who are under 65. Florida goes further and is a frequent exam distinction:
- A disabled beneficiary under 65 receives a 6-month open enrollment when first enrolled in Part B
- They receive a second 6-month window when they turn 65
- After those windows, medical underwriting may apply
- Plan choice may be limited (commonly Plans A, and sometimes B, D, G, K, L depending on the insurer's filings), and premiums for the under-65 block are typically higher
Scenario: a 47-year-old on Social Security Disability enrolls in Part B. Florida gives them a guaranteed-issue Medigap window now, and another at 65 — two bites at the apple, which a non-Florida question would not offer.
Guaranteed-Issue Rights Outside Open Enrollment
Even after the OEP closes, federal/Florida rules grant guaranteed-issue (GI) rights when certain events occur. The deadline to act is almost always 63 days from the qualifying event:
| Triggering event | Guaranteed-issue right |
|---|---|
| Employer or union retiree coverage ends | Buy Medigap within 63 days |
| Medicare Advantage (MA) plan leaves your area or you move out of its service area | Return to Medigap |
| Medigap insurer becomes insolvent or ends coverage through no fault of yours | Switch to a comparable plan |
| Medicare SELECT moves out of its service area | Buy a standard Medigap |
| You drop a Medigap plan to try MA for the first time and want out | Trial-right return (see below) |
The 12-Month Trial Right
If a beneficiary leaves a Medigap policy to try Medicare Advantage for the first time, they have 12 months to change their mind and return — guaranteed issue, no health questions — to their prior Medigap plan if still sold, or to specified plans otherwise. The trial right only applies the first time they enroll in MA.
Standardized Plans A through N
Medigap is federally standardized: a Plan G from any insurer covers exactly the same benefits as a Plan G from any other; insurers compete on price and service, not benefit design.
| Plan | Defining feature |
|---|---|
| A | Core benefits only (baseline every insurer offering Medigap must sell) |
| B | Core + Part A deductible |
| C | Comprehensive incl. Part B deductible (closed post-2020) |
| D | Comprehensive, no Part B excess charges |
| F | Most comprehensive incl. Part B deductible (closed post-2020); high-deductible F also closed |
| G | Like F but does not pay the Part B deductible — top seller for new enrollees |
| K | 50% cost-sharing with annual out-of-pocket maximum |
| L | 75% cost-sharing with annual out-of-pocket maximum |
| M | 50% of Part A deductible |
| N | Copays for some office and ER visits |
Closed-plan rule: anyone first eligible for Medicare on or after January 1, 2020 cannot buy a plan that pays the Part B deductible — that closes Plans C and F (and high-deductible F). Those already eligible before 2020 keep access. Plan G became the de facto replacement.
Pre-Existing Conditions and Rating
During open enrollment
No waiting period applies; the plan covers pre-existing conditions immediately and may not surcharge for health. Prior creditable coverage can reduce or eliminate any waiting period that would otherwise apply.
Outside guaranteed-issue periods
If the beneficiary buys outside a GI window, the insurer may impose up to a 6-month pre-existing condition waiting period for conditions treated or diagnosed in the 6 months before the policy's effective date — reduced by months of prior creditable coverage.
Three rating methods
| Method | How premium behaves | Buyer impact |
|---|---|---|
| Attained age | Rises as the insured grows older | Cheapest early, costliest later |
| Issue age | Fixed by age at purchase; rises only with general inflation | Locks in a younger-age basis |
| Community (no-age) rated | Same premium for everyone regardless of age | No age-based increases |
All Medigap rates and rate increases must be filed with the OIR, and insurers must meet a minimum loss ratio (the share of premium returned as benefits) — generally 65% individual / 75% group for Medicare Supplement.
Marketing Rules and Required Disclosures
Medigap sales are tightly policed. Producers are prohibited from:
- High-pressure tactics or cold-lead advertising disguised as government mail
- Stating or implying the policy is part of Medicare or a government program
- Twisting or misrepresenting coverage to induce a switch
- Selling a beneficiary a duplicate Medigap policy (an applicant must sign a statement that any existing Medigap will be replaced)
Before or at the time of application the producer must deliver:
- An Outline of Coverage summarizing benefits and limits
- The official Guide to Health Insurance for People with Medicare (Buyer's Guide)
- A plain comparison of the standardized plans offered
Medigap also carries a 30-day free look. Scenario: an agent persuades a beneficiary who already owns Plan G to also buy Plan N for "extra protection" — that is an illegal duplicate sale, regardless of the 30-day free look.
