3.2 Rhode Island Medicare Supplement Regulations
Key Takeaways
- The Medigap open enrollment period is six months, beginning the first month a beneficiary is both age 65+ and enrolled in Medicare Part B; it cannot be repeated.
- During open enrollment, Medigap is guaranteed issue with no health underwriting and no pre-existing waiting period beyond a six-month look-back offset by prior creditable coverage.
- Plans are federally standardized A through N; Plans C and F are closed to anyone first eligible for Medicare on or after January 1, 2020.
- Guaranteed-issue rights outside open enrollment generally give the beneficiary a 63-day window after a triggering event such as loss of employer or Medicare Advantage coverage.
- A Medigap policy covers one person only and must be paired with Original Medicare, not Medicare Advantage.
What Medigap Is and Is Not
A Medicare Supplement (Medigap) policy is private insurance that pays the gaps in Original Medicare — deductibles, coinsurance, and copayments under Parts A and B. Three rules drive most exam questions:
- A Medigap policy covers one person. A married couple needs two policies; there is no family Medigap.
- It works only with Original Medicare. It is illegal to sell Medigap to someone enrolled in a Medicare Advantage (Part C) plan unless they are leaving Advantage to return to Original Medicare.
- It does not include drug coverage. Beneficiaries buy a stand-alone Part D plan separately.
The Six-Month Open Enrollment Period
The single most-tested fact: the Medigap open enrollment period (OEP) is six months, and it starts on the first day of the month in which the beneficiary is both age 65 or older AND enrolled in Medicare Part B. It happens once and cannot be restarted.
| During the six-month OEP | Protection |
|---|---|
| Guaranteed issue | Any A–N plan the carrier sells must be issued |
| No medical underwriting | Health questions cannot be used to decline |
| Community/issue-age rate | Cannot charge more for health conditions |
| Pre-existing limit | Look-back capped at six months, offset by prior creditable coverage |
Worked example: Maria turns 65 on March 14 and her Part B starts March 1. Her Medigap OEP runs March 1 through August 31. If she instead delays Part B until she retires at 68, the six months start when Part B begins — the clock keys to Part B enrollment, not merely turning 65.
Exam tip: A common distractor pairs the six-month window with "the month you turn 65." The correct trigger is 65 AND Part B, whichever produces the later start when Part B is delayed.
Why the window matters financially: outside the six months and outside a guaranteed-issue trigger, the carrier can run medical underwriting, decline an applicant outright, or attach a surcharge. A beneficiary who waits, develops a chronic condition, and then tries to buy Medigap can be turned down. Counsel clients to apply during the OEP even if they are healthy, because the one-time guaranteed-issue protection does not return.
Also note RI does not mandate the federal "birthday rule" or annual switching window that a handful of states add, so the six-month OEP and the 63-day triggers are the principal guaranteed-issue paths a producer relies on here.
Guaranteed-Issue Rights Outside Open Enrollment
Once the six-month OEP closes, a carrier may medically underwrite a Medigap applicant — unless a guaranteed-issue (GI) trigger applies. RI follows the federal trigger list, and each generally gives the beneficiary 63 days to apply.
| Triggering event | Window to apply |
|---|---|
| Loss of employer/union retiree coverage | 63 days |
| Voluntarily leaving Medicare Advantage in the trial right (first 12 months) | 63 days |
| Medicare Advantage plan leaves the service area or is terminated | 63 days |
| Medigap insurer becomes insolvent or the policy ends through no fault of the insured | 63 days |
The trial right is worth memorizing: a beneficiary who joined Medicare Advantage when first eligible at 65 may switch back to Original Medicare within 12 months and buy any Medigap plan on a guaranteed-issue basis.
Standardized Lettered Plans
Medigap benefits are federally standardized, so a Plan G is identical in benefits no matter the carrier — only price and service differ. RI uses the standard letters:
| Plan | Notable feature |
|---|---|
| A | Baseline core benefits only |
| B | Core + Part A deductible |
| D | Comprehensive, no Part B excess charges |
| G | Most comprehensive available to new enrollees; covers Part B excess; only the Part B deductible is unpaid |
| K | 50% cost sharing with an out-of-pocket maximum |
| L | 75% cost sharing with an out-of-pocket maximum |
| N | Lower premium with copays up to $20 office / $50 ER |
The C/F closure: Plans C and F pay the Part B deductible. Under federal MACRA rules, they are closed to anyone who became eligible for Medicare on or after January 1, 2020. Someone eligible before that date may still buy or keep C or F. For new enrollees, Plan G is the richest available, and High-Deductible Plan G mirrors the old High-Deductible F.
Two more standardization points the exam likes. First, because benefits are identical across carriers, the only rational reasons to choose one carrier over another are price, financial strength, and service — never "better coverage," since a Plan N is a Plan N everywhere. Second, carriers price Medigap using one of three methods: community-rated (same premium regardless of age), issue-age-rated (premium set by age at purchase and not raised due to aging), or attained-age-rated (premium rises as the insured ages).
Attained-age policies look cheapest at 65 but climb steeply, a classic suitability discussion a producer must document.
Trap: "Plan F is the most comprehensive plan available to a 66-year-old who enrolled in 2024" is false — F is closed to her; Plan G is the answer.
Henry delayed Medicare Part B because he kept working, finally enrolling in Part B at age 68. When does his six-month Medigap open enrollment period begin?
A 66-year-old who first became eligible for Medicare in 2024 wants the Medigap plan that pays the most, including the Part B deductible. What should the producer explain?
