Enrollment, funding, and managed care facts for Iowa Medicaid.
Get Iowa's Medicaid Fee Schedule →Enrollment
Iowa Medicaid covered approximately 0.65-0.67M people. Two independent sources give different-period figures for total Iowa Medicaid/CHIP enrollment: CMS's 2024 Medicaid Managed Care Enrollment and Program Characteristics report counted 649,899 total Medicaid enrollees as of July 1, 2024; KFF's Total Monthly Medicaid & CHIP Enrollment indicator shows 674,796 as of May 2026. Reported as a range rather than a false-precision single number; the increase across this window is plausible (Iowa is an expansion state) but not independently decomposed here.
Funding & federal match
Iowa has adopted ACA Medicaid expansion, effective 2014-01-01.
For FFY2026 (Oct 1, 2025 - Sep 30, 2026), Iowa's Federal Medical Assistance Percentage (FMAP) is 62.7%.
Delivery system & managed care
A large share of Iowa Medicaid is delivered through managed care organizations (MCOs) rather than fee-for-service — estimates range from 93-95% of Medicaid enrollees.
Waivers
Iowa operates Medicaid managed care under the Iowa Wellness Plan / Iowa Health and Wellness Plan (IHAWP), a Section 1115 demonstration waiver. Section 1115 demonstration authorizing Iowa's ACA Medicaid expansion population coverage with healthy-behavior incentives, a Dental Wellness Plan component, and (pending Dec 2026 sunset) non-emergency medical transportation provisions. Approved December 10, 2013, effective January 1, 2014. Current authority runs through December 31, 2026; a temporary extension/amendment was approved by CMS on November 28, 2025 while a formal renewal (including new work requirements effective December 1, 2026) is under review.
