A Health Policy Institute of Ohio data snapshot published July 10, 2026 reports Ohio's effectuated ACA marketplace enrollment fell from 497,443 in February 2025 to 336,058 in February 2026 — "161,000 fewer Ohioans are enrolled in an ACA plan this year" — and states that "Ohio saw the largest drop in the nation in percentage of enrollees who are no longer covered by a marketplace plan."
HPIO notes "Every state except New Mexico saw a decrease in marketplace enrollment from 2025 to 2026," with New Mexico up 14%. The two absolute figures imply a decline of roughly 32%, consistent with KFF's separately published state percentages.
Average premiums more than doubled in 27 Ohio counties, with the ten steepest increases running from about +136% to +161% and concentrated in Appalachian and rural counties: Clark, Pike, Vinton, Adams, Jackson, Crawford, Hardin, Highland, Scioto and Coshocton. Ohioans who remain covered shifted sharply toward lower-cost bronze plans (43% to 60%) and away from silver (52% to 36%), and HPIO warns bronze enrollees "are also not eligible for subsidies for cost-sharing expenses such as deductibles and co-payments."
The underlying data is CMS Health Insurance Exchanges Monthly Effectuated Enrollment, so these are OBSERVED COUNTS, not projections. This materially supersedes the "at least 113,000" marketplace-loss PROJECTION we track separately for Ohio: the observed figure is roughly 40% larger.
Cross-reference the two; do not add them together. HPIO does not name FQHCs — the health-center relevance is that these are newly uninsured or underinsured patients who fall to sliding-fee schedules.
Note the convergence worth planning around: the same Appalachian counties where premiums more than doubled (Pike, Adams, Jackson, Scioto, Vinton, Highland) substantially overlap the six counties Ohio is reportedly declining to grant Medicaid hardship exemptions to.
