3.2 Arkansas Medicare Supplement (Medigap) Regulations

Key Takeaways Explain This Topic AI

The 6-month Medigap open enrollment begins the first month a person is both age 65+ and enrolled in Medicare Part B, with guaranteed issue and no underwriting.

Medigap plans are federally standardized A through N; Plans C and F are closed to people newly eligible for Medicare on or after January 1, 2020.

Plans K and L cap annual out-of-pocket costs (cost-sharing percentages), and high-deductible Plans F and G exist.

Arkansas does NOT have a birthday rule; outside open enrollment or a guaranteed-issue event, insurers may medically underwrite.

An insurer may impose at most a 6-month pre-existing condition wait, reduced by prior creditable coverage.

The 6-Month Open Enrollment Period

The single most-tested Medigap fact is the 6-month open enrollment period . It begins automatically on the first day of the month in which the applicant is both age 65 or older AND enrolled in Medicare Part B . During these six months the consumer has powerful, one-time protections:

Guaranteed issue – the insurer must accept the application regardless of health.

No medical underwriting – health questions cannot raise the premium or cause denial.

No pre-existing condition exclusion if the applicant had at least six months of prior creditable coverage; otherwise a maximum 6-month look-back/exclusion may apply.

Free choice of any Medigap plan (A through N) the carrier offers.

This window does not reset. Someone who declines a Medigap plan at 65 and tries to buy one at 70 can be underwritten unless a separate guaranteed-issue event applies. The protection is a one-time, use-it-or-lose-it right tied to that first six months.

Worked Example

A man turns 65 on July 12 and enrolls in Part B effective July 1. His Medigap open enrollment runs July 1 through December 31 . If he instead delays Part B because he is still working under an employer group plan, his six-month clock does not start until the month his Part B becomes effective after he retires. This is why advisors warn that delaying Part B can also delay the only guaranteed, no-underwriting chance to buy any Medigap plan.

How Medigap Differs From Medicare Advantage

The exam frequently tests the contrast between Medicare Supplement (Medigap) and Medicare Advantage (Part C) , because consumers cannot meaningfully use both at once. A producer may not knowingly sell a Medigap policy to someone enrolled in Medicare Advantage unless they are leaving the MA plan.

• Feature Medigap (Supplement) Medicare Advantage (Part C)
• Pairs with Original Medicare (Parts A and B) Replaces Original Medicare delivery
• Pays Deductibles, coinsurance, copays of Original Medicare Bundled benefits, often incl. Part D
• Provider access Any provider that accepts Medicare Usually network (HMO/PPO)
• Standardized Yes, federally (A–N) No, varies by carrier/plan
• Underwriting after enrollment Yes, outside protected windows Annual election period, no health questions
• No Birthday Rule in Arkansas

Exam alert: Unlike California, Oregon, and a handful of other states, Arkansas does NOT have a birthday rule. There is no annual window letting a beneficiary switch to an equal-or-lesser Medigap plan without underwriting. Outside open enrollment or a guaranteed-issue situation, Arkansas insurers may use full health underwriting and may decline an applicant.

Standardized Plans A Through N

Medigap is federally standardized: a Plan G sold by any carrier in Arkansas covers exactly the same benefits as a Plan G from any other carrier; only price and service differ. A critical rule: Plans C and F are closed to anyone first eligible for Medicare on or after January 1, 2020 , because both cover the Part B deductible, which newly eligible beneficiaries may no longer have fully covered. People already eligible before 2020 can keep or still buy C and F.

• Plan Defining Feature
• A Core benefits only (the mandatory baseline)
• B Core + Part A deductible
• C Comprehensive incl. Part B deductible – closed to newly eligible 2020+
• D Like C but no Part B deductible coverage
• F Most comprehensive incl. Part B deductible – closed to newly eligible 2020+
• G Like F but does not cover the Part B deductible (most popular for new enrollees)
• K 50% cost sharing with an annual out-of-pocket maximum
• L 75% cost sharing with an annual out-of-pocket maximum
• M Covers 50% of the Part A deductible
• N Lower premium; copays up to $20 office / $50 ER, and allows Part B excess charges

High-deductible versions of Plan F (legacy) and Plan G are also offered: the consumer pays a high annual deductible (set federally each year) before the plan pays, in exchange for a much lower premium.

Guaranteed-Issue Rights Outside Open Enrollment

Because Arkansas has no birthday rule, the only way to buy Medigap without underwriting after the open-enrollment window is to trigger a federal guaranteed-issue (trial-right or loss-of-coverage) event :

An employer or union group health plan that supplemented Medicare ends.

The beneficiary's Medicare Advantage plan leaves the service area, stops serving Medicare, or the member moves out of its area.

The Medigap insurer goes insolvent or the coverage ends through no fault of the member.

Trial right: the member tried Medicare Advantage for the first time and disenrolls within 12 months to return to Original Medicare.

The member dropped a Medigap policy to join Medicare Advantage and switches back within 12 months.

In each event the applicant typically has a 63-day window from the loss of coverage to apply, and the insurer must waive both underwriting and the pre-existing waiting period.

Common Trap

Guaranteed issue does not mean every plan is available. After a loss-of-coverage event the beneficiary is usually limited to Plans A, B, D, G, K, or L – not the richest plans – and only certain carriers must offer them.
