Ohio expanded Medicaid, so the federal work requirement that takes effect January 1, 2027 applies to its expansion adults. About 659,491 of them (9.6% of an expansion pool of 705,005) 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 224,631 people in Ohio lose coverage by 2034: 204,847 of them still eligible but lost to paperwork and reporting failures, and 19,785 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. Ohio scores 73 of 100 on this model's ex parte capability index, a low band; its eligibility system is OBIE / Ohio Benefits.

Why eligible people lose coverage
Of the 224,631 projected to lose coverage in Ohio, 204,847 meet the requirement or qualify for an exemption but fail to document it. 98,415 of those are working people who cannot prove their hours through data the state can see, and 106,432 qualify for an exemption the state does not detect automatically.
| Group | Projected to lose coverage |
|---|---|
| Variable shifts / on-call work | 27,326 |
| Multiple part-time jobs (aggregation failure) | 20,361 |
| Self-employed (other) | 19,659 |
| Cash-paid construction & trades | 8,236 |
| Volunteering / job training | 7,297 |
| Full-time students not auto-verified | 7,274 |
| Seasonal: agriculture, hospitality, food service | 5,741 |
| Gig / courier (DoorDash, Uber, Lyft, Instacart) | 2,520 |
| Medically frail without auto-match | 45,071 |
| Caregivers of a disabled adult | 32,109 |
| American Indian / Alaska Native (tribal exemption) | 8,213 |
| Kinship caregivers (non-parent) of children ≤13 | 6,154 |
| SUD treatment not flagged in claims data | 5,338 |
| Parent caregivers of children ≤13 without auto-match | 4,798 |
| Recent incarceration (data-match gap) | 2,418 |
| Other categorical exemptions (foster, AYA cancer, SNAP/TANF) | 2,043 |
| Pregnancy / postpartum data lag | 287 |
Can the state renew people automatically?
The ex parte capability index blends the state's observed automatic-renewal rate (80% in CMS eligibility-processing data), the wage, disability, and other data sources it can query, and its history of churn. Ohio's composite score is 73 (low 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 | 73 |
| Observed ex parte | 80 |
| Core capability | 78 |
| Data sources | 72 |
| 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.
