It also has a strong 4.5-star CMS rating and broad coverage in 57 counties. Aetna Medicare and Devoted Health also rank highly, with Devoted earning Iowa's only 5-star CMS rating, though it's available in just 8 counties.

Iowa offers 42 non-SNP Medicare Advantage plans from 10 insurance companies in 2026. Plan availability varies by location, with the median county offering 18 options. Overall, 81% of plans charge no monthly premium.

Medicare Advantage plans provide Medicare Part A and Part B coverage through private insurers, often with benefits beyond Original Medicare. Vision coverage is included with 92.9% of Iowa plans, while 83.3% offer dental benefits and 35.7% include hearing coverage.

Iowa plans have a median annual out-of-pocket maximum of $4,950, but individual limits range from $3,500 to $9,250. HMOs have the lowest median limit at $4,200, compared with $4,950 for PPOs and $5,900 for HMO-POS plans. PPOs allow greater provider flexibility but have the highest median specialist copay in the state at $40 per visit.

The best Medicare Advantage plan depends on your health needs, budget and where you live in Iowa. Plans vary by county, so a top-rated option in Des Moines won't necessarily be available in rural areas like Mason City or Ottumwa.

Most Iowa Medicare Advantage plans have a $0 monthly premium, but maximum out-of-pocket limits provide a fuller picture of annual costs.
