What we hold in Ohio.

|---|---|---|---|---|
| Marketplace (ACA) | 189 | 10 | 2026 | 2026-10-29 |

How we count: a plan counts when its provider directory lists at least one provider in our data. A provider-plan link is one listing of one provider in one plan. For marketplace plans it counts each plan year and network tier the directory gives; for Medicare Advantage plans it counts each provider once per plan.
