3.2 Minnesota Medicare Supplement (Medigap) Regulations
Key Takeaways
- Minnesota is one of only three waiver states (with Massachusetts and Wisconsin) that does NOT use standardized Plans A through N
- Minnesota offers two core Medigap forms — the Basic Plan and the Extended Basic Plan — plus optional riders and MN versions of K, L, M, and N
- The Medigap open enrollment period lasts 6 months and begins when the applicant is 65+ AND enrolled in Medicare Part B
- Guaranteed issue applies during open enrollment and during specific triggering events with a 63-day window
- Medigap does not cover long-term custodial care, dental, vision, hearing aids, or private-duty nursing
Minnesota Is a Medigap "Waiver State" — Memorize This
This is the single most-tested and most-misunderstood Minnesota fact. The federal Medigap standardization that created lettered Plans A through N does not apply in three waiver states: Massachusetts, Minnesota, and Wisconsin. Minnesota received its waiver before standardization and keeps its own plan design.
So if a national study aid tells you to compare "Plan F" and "Plan G" in Minnesota, that framework is incorrect for this state exam. Minnesota instead sells:
- A Basic Plan (the core mandatory benefit package)
- An Extended Basic Plan (a richer package with additional cost-sharing coverage)
- A menu of optional riders attached to the Basic Plan
- Minnesota-specific versions of Plans K, L, M, and N
- A high-deductible option
Basic Plan vs. Extended Basic Plan
| Benefit Area | Basic Plan | Extended Basic Plan |
|---|---|---|
| Part A coinsurance + 365 extra lifetime hospital days | Covered | Covered |
| Part B coinsurance (usually 20%) | Covered | Covered |
| First 3 pints of blood | Covered | Covered |
| Part A hospice cost-sharing | Covered | Covered |
| Part A deductible | Optional rider | Covered |
| Part B deductible | Not standard | Covered |
| Skilled nursing coinsurance | Limited | Broader |
| Foreign travel emergency | Optional rider | Covered |
Optional riders a consumer can add to the Basic Plan include the Part A deductible rider, the Part B deductible rider (for those Medicare-eligible before Jan. 1, 2020), a usual-and-customary fees rider, and a foreign travel emergency rider. The Extended Basic Plan bundles most of these in automatically, which is why its premium is higher.
Exam trap: "Minnesota requires standardized Plans A through N." That statement is false — Minnesota is a waiver state using Basic and Extended Basic.
Open Enrollment Period
Minnesota follows the federal 6-month Medigap open enrollment period (OEP). It begins on the first day of the month in which the applicant is both age 65 or older AND enrolled in Medicare Part B, and it is a one-time window that does not reset.
During OEP the applicant gets:
- Guaranteed issue — accepted regardless of health
- No medical underwriting and no pre-existing condition waiting period
- Community/standard pricing — cannot be surcharged for health status
Exam tip: OEP is the only time guaranteed issue is automatically available to every eligible person. Miss it, and the insurer may underwrite outside the protected situations below.
Guaranteed Issue Outside Open Enrollment
Minnesota grants additional guaranteed-issue (GI) rights when specific triggering events occur. The beneficiary generally must apply within 63 days of losing the prior coverage.
| Triggering Event | Guaranteed-Issue Right |
|---|---|
| Loss of employer/group retiree coverage | Buy Medigap within 63 days |
| Medicare Advantage plan exits the service area | Return to Medigap |
| "Trial right" — first MA enrollment, disenroll within 12 months | Return to Medigap |
| Medigap insurer becomes insolvent | Switch to comparable plan |
| Loss of Medical Assistance (Medicaid) | Buy Medigap |
Rating Methods and Pre-Existing Conditions
Minnesota permits insurers to file premiums using attained-age, issue-age, or community rating; all rate changes must be filed with the Department of Commerce.
| Situation | Pre-Existing Waiting Period |
|---|---|
| During open enrollment | None |
| Triggered guaranteed issue | None |
| Underwritten application outside both | Up to 6 months may apply |
Prior creditable coverage reduces or eliminates any waiting period day-for-day.
What Medigap Never Covers
A recurring exam item: Medigap supplements Original Medicare only and does not cover long-term custodial care, routine dental, vision, hearing aids, eyeglasses, or private-duty nursing. It also cannot be paired with a Medicare Advantage plan.
Replacement, Suitability, and Required Disclosures
When a producer replaces an existing Medigap policy, Minnesota requires a replacement notice signed by the applicant, and the new policy must waive any pre-existing waiting period already satisfied under the old coverage so the insured is not penalized twice. Producers must also deliver the federal "Guide to Health Insurance for People with Medicare" at or before application and the carrier's outline of coverage.
Minnesota prohibits knowingly selling a duplicate or unnecessary policy. Selling a Medigap policy to someone already enrolled in a Medicare Advantage plan, or stacking two Medigap policies, is an unfair trade practice. Producers must screen for Medicaid/Medical Assistance eligibility, because Medigap is rarely suitable for a dual-eligible whose cost-sharing is already covered.
| Required at Medigap Sale | Purpose |
|---|---|
| "Guide to Health Insurance for People with Medicare" | Standardized federal disclosure |
| Outline of coverage | Summarizes Basic vs. Extended Basic benefits |
| Replacement notice (if replacing) | Prevents unnecessary churn and waiting periods |
Worked Enrollment Scenario
Marta turns 65 on June 14 and enrolls in Part B effective June 1. Her Medigap open enrollment period runs June 1 through November 30 — six months of automatic guaranteed issue. If she instead delays Part B while still working under a large-employer group plan, her open enrollment does not start until she finally enrolls in Part B, and a separate 63-day guaranteed-issue window protects her when the employer coverage ends. Understanding this timing prevents the classic mistake of telling a still-working 65-year-old to buy Medigap immediately.
