3.2 Alabama Medicare Supplement (Medigap) Regulations
Key Takeaways
- The Medigap open enrollment period is the 6 months beginning the first month the insured is both age 65 and enrolled in Medicare Part B
- During open enrollment Medigap is guaranteed issue with no underwriting and no pre-existing waiting period for prior creditable coverage
- Alabama gives Medigap policies a 30-day free look, longer than the 10-day A&H window
- Alabama does NOT have a Birthday Rule, so outside protected windows insurers may medically underwrite
- ALDOI reviews and approves Medicare Supplement rates — an exception to Alabama's general non-regulation of health rates
Medigap Basics and Standardized Plans
Medicare Supplement insurance (Medigap) is private coverage that pays the deductibles, copays, and coinsurance left by Original Medicare (Parts A and B). Plans are standardized by federal law into Plans A through N, so a Plan G from any Alabama insurer carries identical benefits — carriers compete only on price and service.
| Plan | Defining feature |
|---|---|
| A | Core benefits only |
| B | Core + Part A deductible |
| F | Most comprehensive; pre-2020 eligibles only |
| G | Like F but does not cover the Part B deductible |
| K / L | Cost-sharing plans (50% / 75%) with an out-of-pocket maximum |
| N | Lower premium; office-visit and ER copays |
Exam trap: Plans C and F are closed to anyone who became Medicare-eligible on or after January 1, 2020. For new beneficiaries, Plan G is the most comprehensive option available.
Free Look on Medigap
Alabama gives Medigap policies a 30-day free look, longer than the 10-day A&H period. This 30-day window lets a senior keep an existing policy while testing a new one and return the new policy for a full refund — useful guidance when replacing coverage.
What Medigap Does and Does Not Cover
Medigap fills gaps in Original Medicare only. It does not work with Medicare Advantage (Part C) — it is illegal to sell a Medigap policy to someone on an Advantage plan unless they are leaving it. Medigap also does not cover prescription drugs (that requires a separate Part D plan), long-term custodial care, dental, vision, or hearing. A Medigap policy covers one person, so a married couple needs two policies. These boundaries are heavily tested: the most common error is assuming Medigap pays for nursing-home custodial care, which it does not.
Enrollment Mechanics in Alabama
A producer guiding a senior should map the timeline: most people enroll in Part B during their Initial Enrollment Period (the 7 months around the 65th birthday), which automatically starts the 6-month Medigap window. Someone still working past 65 with employer coverage may delay Part B without penalty and trigger a later Medigap window — and a guaranteed-issue right — when that group coverage ends.
Producers must also avoid prohibited acts: high-pressure tactics, selling duplicate Medigap policies, and failing to deliver the required outline of coverage and the official Medicare buyer's guide are all violations subject to ALDOI enforcement.
Open Enrollment Period
The Medigap open enrollment period (OEP) is the single best time to buy. It lasts 6 months, beginning the first day of the month in which the applicant is both age 65 or older AND enrolled in Medicare Part B. During this window the applicant gets:
- Guaranteed issue — the insurer must accept the applicant regardless of health
- No medical underwriting and no rate-up for health conditions
- No pre-existing condition waiting period when prior creditable coverage is credited
- Free choice of any Medigap plan (A–N) the carrier offers
This OEP is a one-time, use-it-or-lose-it window. Miss it and, outside the guaranteed-issue triggers below, the carrier may underwrite.
No Birthday Rule
A handful of states (California, Oregon, others) have a Birthday Rule letting beneficiaries switch to an equal-or-lesser Medigap plan each year around their birthday without underwriting. Alabama does NOT have a Birthday Rule. Outside open enrollment or a guaranteed-issue event, an Alabama insured who wants to change plans is generally subject to health underwriting and can be declined.
Rate Regulation — a Health-Insurance Exception
Under Ala. Code 27-13-2, ALDOI does not rate-regulate most health premiums. Medicare Supplement is an exception: insurers must file Medigap rates and rate increases with ALDOI, which reviews them for reasonableness. This extra layer protects seniors from arbitrary increases. (Medigap is grouped with HMO and long-term care rates, the other reviewed health products.)
Guaranteed-Issue Rights Beyond Open Enrollment
Even after the 6-month OEP closes, federal law preserves guaranteed-issue rights in specific situations. The applicant generally has 63 days from the loss of prior coverage to buy a Medigap plan with no underwriting.
| Triggering event | Guaranteed-issue right |
|---|---|
| Loss of employer/retiree group coverage | Buy Medigap within 63 days |
| Medicare Advantage plan leaves the service area | Buy Medigap (Plan A, B, D, G, K, or L) |
| Medigap insurer becomes insolvent or ends coverage | Switch to a comparable plan |
| Loss of Medicaid eligibility | Buy Medigap |
Trial Right (12-Month Rule)
A beneficiary who drops Medigap to try Medicare Advantage for the first time, or switches to Advantage at age 65, has 12 months to change course. If they return to Original Medicare within that year, they may go back to their former Medigap plan on a guaranteed-issue basis (or, if unavailable, any plan from that insurer with equal or lesser benefits).
Pre-Existing Conditions
Outside open enrollment, a Medigap insurer may impose up to a 6-month pre-existing condition waiting period, but only for conditions treated or diagnosed within 6 months before the policy's effective date. Prior creditable coverage reduces or eliminates this look-back day-for-day.
A man turns 65 on June 20 and enrolls in Medicare Part B effective June 1. When does his 6-month Medigap open enrollment period end?
