What we hold in Wisconsin.
Plans whose provider directories list providers in our data. Together the marketplace plans hold more than 20 million provider-plan links.
| MARKET | PLANS | INSURERS | PLAN YEARS | LATEST READ |
|---|---|---|---|---|
| Marketplace (ACA) | 284 | 11 | 2026 | 2026-10-29 |
| Medicare Advantage | 4 | 1 | 2027 | 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.
