3.2 Alaska Medicare Supplement (Medigap) Regulations

The 6-Month Open Enrollment Window

Medicare Supplement (Medigap) policies pay the gaps in Original Medicare — deductibles, coinsurance, and copays. The single most-tested Alaska rule is the 6-month Medigap open enrollment period (OEP).

The window opens on the first day of the month in which the applicant is both:

• age 65 or older, and
• enrolled in Medicare Part B.

It is a one-time window and does not reset annually. During those six months the applicant has the strongest possible rights:

• Guaranteed issue — the insurer must accept the applicant regardless of health.
• No pre-existing condition waiting period if the applicant had at least 6 months of prior creditable coverage.
• No health-based rate-up — the applicant pays the same rate as a healthy buyer.
• Any plan offered by the insurer, A through N, is available.

Trap: The trigger is age 65 plus Part B, not merely turning 65. Someone who delays Part B because of active employer coverage does not start the clock until Part B begins.

No Birthday Rule

A handful of states (notably California) have a Birthday Rule that lets enrollees switch to an equal or lesser Medigap plan each year around their birthday without underwriting. Alaska has no Birthday Rule.

Worked example: Bob, age 70, has Plan G and feels healthy. He wants to switch to a cheaper Plan N. In California a Birthday Rule might let him do this without health questions; in Alaska the new insurer may ask health questions and decline him. The right advice is to apply only when a guaranteed issue right exists.

Guaranteed Issue Triggering Events

Outside the 6-month OEP, federal guaranteed issue (GI) rights still protect applicants after certain events, generally with a 63-day application window:

During a GI event the insurer cannot deny coverage, cannot impose a pre-existing condition waiting period, and cannot charge more for health status — but the menu of plans may be limited to A, B, C, D, F, G, K, or L depending on eligibility date.

The Medicare Advantage Trial Right

Alaska honors the federal trial right. A beneficiary who drops a Medigap policy to try a Medicare Advantage (MA) plan for the first time may change their mind within 12 months and:

• return to the exact same Medigap policy if the insurer still sells it, or
• buy any Medigap plan A, B, C, D, F, G, K, or L from any insurer in the state,
• on a guaranteed issue basis with no health questions.

The same 12-month trial right applies to someone who joined an MA plan when first eligible for Medicare at 65 and disenrolls within the first year.

Standardized Plans A Through N

Medigap plans are federally standardized, so a Plan G in Alaska covers exactly what a Plan G covers anywhere else — only price and service differ. Memorize which plans are closed.

Trap: Plans C and F are barred for anyone who became eligible for Medicare on or after January 1, 2020, because both cover the Part B deductible. People eligible before that date may keep or buy them.

Rating Methods and Pre-Existing Conditions

Alaska permits three rating methods, all subject to Division rate filing:

• Attained-age — premium rises as the insured ages (cheapest at issue, costliest later).
• Issue-age — premium locked to age at purchase; does not rise with age.
• Community — same premium regardless of age.

Pre-existing conditions: During open enrollment, no waiting period applies. Outside open enrollment an insurer may impose up to a 6-month waiting period for conditions treated or diagnosed in the 6 months before the effective date, reduced by any prior creditable coverage.

What Medigap Does and Does Not Cover

Medigap fills gaps in Original Medicare (Parts A and B) only. It is critical for the exam to keep these boundaries straight:

• Medigap pays the Part A hospital deductible, coinsurance, and skilled nursing facility coinsurance, plus the Part B 20% coinsurance, depending on plan letter.
• Medigap does not include prescription drug coverage — that requires a separate Part D plan.
• A beneficiary cannot hold both a Medigap policy and a Medicare Advantage plan at the same time; Medigap pays nothing toward MA cost sharing.
• It is illegal for a producer to sell a second Medigap policy to someone who already has one, or to sell Medigap to someone enrolled in Medicaid.

Trap: A common distractor claims Medigap includes drug coverage. Since 2006, newly issued Medigap plans exclude drugs; the buyer needs a stand-alone Part D plan.
