Oregon expanded Medicaid, so the federal work requirement that takes effect January 1, 2027 applies to its expansion adults. About 644,844 of them (25.3% of an expansion pool of 689,347) 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 192,348 people in Oregon lose coverage by 2034: 173,003 of them still eligible but lost to paperwork and reporting failures, and 19,345 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. Oregon scores 74 of 100 on this model's ex parte capability index, a low band; its eligibility system is ONE.

Why eligible people lose coverage
Of the 192,348 projected to lose coverage in Oregon, 173,003 meet the requirement or qualify for an exemption but fail to document it. 72,496 of those are working people who cannot prove their hours through data the state can see, and 100,506 qualify for an exemption the state does not detect automatically.
| Group | Projected to lose coverage |
|---|---|
| Multiple part-time jobs (aggregation failure) | 23,588 |
| Self-employed (other) | 16,811 |
| Variable shifts / on-call work | 13,948 |
| Full-time students not auto-verified | 5,074 |
| Volunteering / job training | 3,924 |
| Seasonal: agriculture, hospitality, food service | 3,830 |
| Cash-paid construction & trades | 3,528 |
| Gig / courier (DoorDash, Uber, Lyft, Instacart) | 1,794 |
| Medically frail without auto-match | 43,237 |
| Caregivers of a disabled adult | 27,850 |
| American Indian / Alaska Native (tribal exemption) | 10,433 |
| Parent caregivers of children ≤13 without auto-match | 7,220 |
| SUD treatment not flagged in claims data | 6,113 |
| Kinship caregivers (non-parent) of children ≤13 | 2,384 |
| Other categorical exemptions (foster, AYA cancer, SNAP/TANF) | 1,998 |
| Recent incarceration (data-match gap) | 992 |
| Pregnancy / postpartum data lag | 280 |
Can the state renew people automatically?
The ex parte capability index blends the state's observed automatic-renewal rate (79% in CMS eligibility-processing data), the wage, disability, and other data sources it can query, and its history of churn. Oregon's composite score is 74 (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 | 74 |
| Observed ex parte | 79 |
| Core capability | 93 |
| Data sources | 76 |
| 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.
