Iowa is one of the most affordable states for Medicare Supplement (Medigap) insurance, with average Plan G premiums around $142 per month. With over 550,000 Medicare beneficiaries and relatively low Medicare Advantage penetration, most Iowa seniors rely on Original Medicare paired with a Medigap plan for comprehensive coverage.
Why Iowa Residents Choose Medigap Over Medicare Advantage
Iowa has one of the lower Medicare Advantage penetration rates in the country, with roughly 36% of Medicare beneficiaries enrolled in MA plans. That means nearly two-thirds of Iowa’s seniors stick with Original Medicare — and most pair it with a Medigap policy for predictable out-of-pocket costs. Iowa’s rural geography means many residents prefer Medigap plans that let them see any doctor who accepts Medicare, without network restrictions that can limit access in less populated areas.
Plan G vs. Plan N in Iowa: Which Is Right for You?
Plan G is the most comprehensive Medigap plan available to new enrollees. It covers everything except the Medicare Part B deductible ($257 annually). Once you meet that deductible, Plan G pays 100% of your Medicare-approved costs with no copays, no coinsurance, and no surprise bills.
Plan N offers slightly less coverage at a lower premium. You’ll pay up to $20 for some office visits and up to $50 for emergency room visits that don’t result in admission. However, Plan N premiums in Iowa typically run $25–$40 less per month than Plan G, which can save you $300–$480 annually.

How Iowa Regulates Medigap Pricing
Iowa allows insurance carriers to use either attained-age or issue-age rating methods for Medigap pricing. Most carriers in Iowa use attained-age rating, meaning your premium may increase as you get older. Issue-age carriers like United American and State Farm lock in your rate based on the age you enroll, which can be advantageous if you sign up at 65.
Iowa does not currently have a Medigap birthday rule. However, Iowa law does provide important protections: during your Medigap Open Enrollment Period (the 6-month window starting when you turn 65 and enroll in Part B), insurance companies cannot deny you coverage or charge more due to pre-existing conditions. The Iowa Insurance Division and SHIIP (Senior Health Insurance Information Program) at (800) 351-4664 provide free counseling to help you compare plans.
