Medigap premiums vary by carrier, age, and ZIP code. The 2026 Part B premium is $202.90/month and Part B deductible is $283. Part D out-of-pocket cap is $2,100 in 2026.
Iowa consistently ranks among the states with the lowest Medigap Plan G premiums in the country — approximately $116/month at age 65 — reflecting both a lower cost of healthcare delivery and an older but relatively healthy rural population. Wellmark Blue Cross Blue Shield is the dominant carrier in Iowa's commercial and Medigap markets, with deep relationships with major systems like UnityPoint Health and MercyOne (now part of CommonSpirit Health). The MA market in Iowa is less developed than national averages, at about 42% enrollment, partly because the competitive Medigap pricing makes Original Medicare a financially attractive alternative.
Iowa's largely rural character means that outside of Des Moines, Cedar Rapids, and Davenport, MA plan networks can be thin. The Quad Cities market, which spans Iowa and Illinois, benefits from cross-border provider availability and competitive MA plan offerings. Iowa beneficiaries in rural areas often value the freedom of Original Medicare plus Medigap to access Iowa City's University of Iowa Hospitals — a major academic medical center — without network restrictions. Iowa has no birthday rule or annual Medigap switching protections, but given the low premium environment, initial enrollment strategy is manageable for most beneficiaries.
In Iowa, traditional Medicare combined with a Medigap supplement (typically Plan G or N) plus a stand-alone Part D plan provides nationwide access with predictable costs. Plan G covers everything except the $283 Part B deductible.
Medicare Advantage (Part C) plans bundle Medicare Parts A, B, and usually D into one private plan, often with $0 premium beyond Part B. Trade-offs include network restrictions and prior authorization. 42% of Iowa beneficiaries currently choose MA.
No state annual GI rights; Iowa has some of the lowest Medigap premiums in the nation.
💡 Iowa Pro Tip
Iowa beneficiaries in Des Moines and Cedar Rapids typically have access to 25 or more Medicare Advantage plans. Rural Iowa counties may have 10 to 20 options. Wellmark Blue Cross Blue Shield and UnitedHealthcare are the dominant carriers, with Humana also offering plans in metro markets.
Iowa has some of the lowest Medigap Plan G premiums in the country, averaging approximately $116 per month for a 65-year-old. This makes Original Medicare plus Medigap an excellent value in Iowa, and many beneficiaries choose this path over Medicare Advantage precisely because of the affordable premium environment.
Iowa does not have a birthday rule or annual guaranteed-issue protections for Medigap. Outside your 6-month open enrollment at 65 or a qualifying federal event, carriers can apply medical underwriting. Given Iowa's very low Medigap premiums, locking in a plan during open enrollment is a financially sound strategy.
