Iowa expanded Medicaid, so the federal work requirement that takes effect January 1, 2027 applies to its expansion adults. About 167,800 of them (9.1% of an expansion pool of 179,380) will have to prove 80 hours a month of work, school, or service, or an exemption, to keep coverage.
This model's bottom-up estimate is that 74,381 people in Iowa lose coverage by 2034: 69,347 of them still eligible but lost to paperwork and reporting failures, and 5,034 not meeting the requirement. Nationally the same model gives 5,461,400, against CBO's 5,200,000.
Whether those eligible people keep coverage depends on the state's ability to renew them automatically (ex parte) from data it already holds. Iowa scores 56 of 100 on this model's ex parte capability index, a mid band; its eligibility system is ABE.

Why eligible people lose coverage
Of the 74,381 projected to lose coverage in Iowa, 69,347 meet the requirement or qualify for an exemption but fail to document it. 29,376 of those are working people who cannot prove their hours through data the state can see, and 39,971 qualify for an exemption the state does not detect automatically.
| Group | Projected to lose coverage |
|---|---|
| Variable shifts / on-call work | 7,773 |
| Multiple part-time jobs (aggregation failure) | 6,912 |
| Self-employed (other) | 6,648 |
| Full-time students not auto-verified | 2,213 |
| Cash-paid construction & trades | 2,006 |
| Volunteering / job training | 1,857 |
| Seasonal: agriculture, hospitality, food service | 1,127 |
| Gig / courier (DoorDash, Uber, Lyft, Instacart) | 841 |
| Medically frail without auto-match | 15,823 |
| Parent caregivers of children ≤13 without auto-match | 9,118 |
| Caregivers of a disabled adult | 5,403 |
| SUD treatment not flagged in claims data | 3,093 |
| American Indian / Alaska Native (tribal exemption) | 2,418 |
| Kinship caregivers (non-parent) of children ≤13 | 1,801 |
| Recent incarceration (data-match gap) | 1,336 |
| Other categorical exemptions (foster, AYA cancer, SNAP/TANF) | 866 |
| Pregnancy / postpartum data lag | 113 |
Can the state renew people automatically?
The ex parte capability index blends the state's observed automatic-renewal rate (59% in CMS eligibility-processing data), the wage, disability, and other data sources it can query, and its history of churn. Iowa's composite score is 56 (mid band). A low score means more eligible people will be dropped for paperwork unless the state changes its process before January 1, 2027.
| Component | Score |
|---|---|
| Composite | 56 |
| Observed ex parte | 59 |
| Core capability | 43 |
| Data sources | 55 |
| Historical churn | 50 |

State brief and methodology
Estimates, not counts. The model rakes to CBO's national subject total and allocates by ACS microdata; state agencies hold the administrative data that would replace these figures.
