What You Need to Know
- Medicare Supplement plans, also known as Medigap, help pay for out-of-pocket costs not covered by Medicare Part A and Part B.
- Iowa insurance companies must accept your Medicare Supplement (Medigap) plan application if you’re in your Medigap Open Enrollment Period or have guaranteed issue rights.
- The three most popular Medigap policies are typically Plans F, G, and N.
What Are Medicare Supplement Plans in Iowa?
Medicare is a federal health insurance program for individuals aged 65 and older, as well as younger people with qualifying disabilities or certain health conditions like end-stage renal disease (ESRD).
Original Medicare includes Part A (Hospital Insurance) and Part B (Medical Insurance). While it covers many services, it doesn’t pay for all healthcare costs. You’re still responsible for deductibles, copayments, and coinsurance. Medicare Supplement plans, also known as Medigap, help cover those expenses.
These plans are standardized by letter (A through N). This means a Plan G policy provides the same benefits no matter which insurance company offers it—though premiums may vary by provider.
Medigap plans are a valuable resource for Iowa residents who want more predictable healthcare costs.
When Can You Enroll in a Medicare Supplement (Medigap) Policy?
You can apply for a Medigap policy at any time. However, outside your Medigap Open Enrollment Period—or if you don’t have guaranteed issue rights—insurers may use your health history to deny your application or charge you more.
Your Medigap Open Enrollment Period begins when you are both 65 (or older) and enrolled in Medicare Part B. It lasts for six months. During this time, Iowa insurers must offer you any Medigap policy they sell without charging more or asking health questions.
Guaranteed issue rights occur under certain circumstances—such as losing other health coverage—that require insurers to sell you a plan regardless of your health. These rights protect you from being denied coverage or charged more because of medical conditions.

What Are the Most Popular Medicare Supplement Plans?
In Iowa, the most commonly selected Medigap plans are:
- Plan F: Provides the most comprehensive coverage, including all Medicare-approved out-of-pocket expenses. Only available to those eligible for Medicare before January 1, 2020.
- Plan G: Covers nearly everything Plan F does, except the Medicare Part B deductible.
- Plan N: Offers robust coverage, but you may pay copayments for doctor visits and emergency room care. It also does not cover Part B excess charges.
These plans are favored for their broad coverage and ability to reduce or eliminate surprise healthcare costs.
How Do You Choose a Medicare Supplement Plan?
To choose the best Medigap plan in Iowa:
- Select a plan letter that matches your healthcare needs and budget.
- Compare premiums from different insurers. While benefits are standardized, pricing structures vary.
- Understand pricing models used by insurers:
- Attained age rating: Premiums increase as you get older.
- Issue age rating: Premiums are based on your age at purchase and don’t rise due to age.
- Community rating: Everyone pays the same premium regardless of age.
Always compare the same plan across insurers—for example, Plan N vs. Plan N—to ensure you’re comparing equivalent coverage.

How Much Do Medigap Policies Cost?
Medigap premiums in Iowa vary depending on:
- Your age and gender
- Whether you use tobacco
- The specific plan you choose
- The pricing method used by the insurer
Rates differ by provider, even for identical plans, so it’s important to shop around.

What If You Want to Change Your Medicare Supplement Plan?
You can apply to change your Medigap plan at any time. However, unless you qualify for guaranteed issue rights, your new insurer may evaluate your health and choose to increase premiums or deny coverage.
Iowa does not impose specific restrictions on when you can change Medigap plans, but switching after your Open Enrollment Period may be subject to medical underwriting.
What Are Alternatives to Medicare Supplement Plans?
Medicare Advantage plans, also called Part C, are an alternative to Original Medicare, offered by private insurance companies approved by Medicare.
These plans include Part A and Part B, and most also offer prescription drug coverage (Part D). Many also include added benefits like vision, dental, hearing, and fitness services.
If you enroll in a Medicare Advantage plan, you cannot have a Medigap plan at the same time. Medicare Advantage may be a suitable option if you prefer bundled coverage with additional benefits.

Medicare Part D?
Medicare Part D plans offer standalone prescription drug coverage for those with Original Medicare.
- Who needs it: If you’re enrolled in Medicare Parts A and/or B and need drug coverage.
- What it covers: A range of prescription medications, with variations in formulary and cost.
- How it’s offered: Through Medicare-approved private insurers.
- Not needed if: You have a Medicare Advantage plan that includes prescription drug coverage (MAPD).

Do Medigap Plans Cover Prescription Drugs?
No, Medigap plans do not cover prescription medications. You’ll need to purchase a separate Medicare Part D plan for prescription drug benefits.
