3.2 Iowa Medicare Supplement (Medigap) Regulations

Medigap Open Enrollment in Iowa

A Medicare Supplement (Medigap) policy pays the deductibles, coinsurance, and copayments that Original Medicare (Parts A and B) leaves to the beneficiary. Iowa gives every new beneficiary a single 6-month open enrollment period. The window 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 ends six months later.

Why the Trigger Matters

Both conditions must be met. A 64-year-old already on Part B due to disability has not triggered the 65-based open enrollment; their window opens when they turn 65. Someone who turns 65 but delays Part B (still working with group coverage) has not started the clock either — it begins when Part B takes effect. The exam loves this two-condition test.

Guaranteed Issue During Open Enrollment

During the 6-month window the applicant has guaranteed issue rights:

• The insurer cannot deny any Medigap plan it sells in Iowa.
• The insurer cannot use health underwriting or impose a health-based surcharge.
• The insurer cannot impose a pre-existing-condition waiting period if the applicant had at least 6 months of prior creditable coverage; otherwise a waiting period of up to 6 months is allowed.

No Birthday Rule in Iowa

A frequent trap: some states (California, Oregon, Nevada, Idaho) have a birthday rule letting beneficiaries switch Medigap plans annually around their birthday with no underwriting. Iowa has no such rule. Outside open enrollment or a guaranteed-issue event, an Iowa applicant who wants to switch Medigap plans is generally subject to medical underwriting and can be declined or surcharged.

Standardized Plan Letters

Medigap plans are federally standardized; a Plan G in Iowa carries the identical core benefits as a Plan G anywhere else, so insurers compete on price and service, not benefit design. Beneficiaries first eligible on or after January 1, 2020 cannot buy Plans C or F, because those plans covered the Part B deductible, which newly eligible enrollees may no longer have paid for them.

Guaranteed-Issue Events Beyond Open Enrollment

Iowa grants guaranteed issue (usually 63 days to apply) when a beneficiary involuntarily loses coverage, including:

• Loss of employer or union retiree health coverage that supplemented Medicare.
• A Medicare Advantage plan leaving the service area or terminating.
• Disenrolling from Medicare Advantage during the 12-month trial right after first joining at 65.
• The Medigap insurer becoming insolvent or the plan being discontinued through no fault of the insured.

Producer Duties: Disclosure, Replacement, and Marketing

Iowa enforces strong consumer protections for the Medicare population:

• Outline of coverage must be delivered at or before application; the official "Guide to Health Insurance for People with Medicare" (the CMS buyer's guide) must be delivered no later than policy delivery.
• 30-day free look on Medigap policies — longer than the 10 days on standard health policies.
• Replacement: when replacing one Medigap policy with another, the producer must furnish a replacement notice, and the applicant must sign a statement; the producer cannot misrepresent benefits to induce the switch.
• Prohibited duplicate coverage: an agent cannot knowingly sell a beneficiary a second Medigap policy that duplicates coverage they already have. High-pressure tactics, cold-lead advertising, and twisting Medicare beneficiaries are unfair practices.

Exam strategy: when two answers seem plausible, pick the one giving the beneficiary clearer disclosure and avoiding pressure or duplication. Iowa Medigap rules exist to let buyers compare standardized benefits and understand what they give up before replacing coverage.

Medigap Versus Medicare Advantage

A frequent point of confusion the state section probes is the difference between a Medicare Supplement (Medigap) policy and a Medicare Advantage (Part C) plan. A Medigap policy works alongside Original Medicare, paying the beneficiary's share of Part A and Part B costs, and lets the member see any provider who accepts Medicare nationwide. A Medicare Advantage plan replaces Original Medicare with a private network plan that often bundles Part D drug coverage and extras like dental or vision.

A beneficiary cannot legally use a Medigap policy to pay cost sharing under a Medicare Advantage plan — it is illegal for a producer to sell a Medigap policy to someone enrolled in Medicare Advantage unless they are disenrolling and returning to Original Medicare.

What Medigap Does Not Cover

Standardized Medigap plans do not cover long-term custodial care, routine dental, routine vision, hearing aids, eyeglasses, or private-duty nursing. They also do not include prescription drug coverage — a beneficiary who wants outpatient drug coverage must enroll in a separate Part D plan. Older Medigap plans sold before 2006 that included drug coverage were discontinued; new plans never include Part D.

Rate-Setting and Premium Pricing

Iowa permits three Medigap pricing methods, and producers should be able to explain them to clients comparing premiums on identical standardized benefits:

• Community-rated (no-age-rated): every policyholder pays the same premium regardless of age.
• Issue-age-rated: premium is based on the age at purchase and does not rise simply because the insured grows older.
• Attained-age-rated: premium is based on current age and increases as the insured ages, often cheapest at 65 but most expensive later.

Because benefits are identical across insurers for a given plan letter, price and the rating method are the real differentiators — a key talking point the exam frames as suitability.
