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.

Where: 19 states.

Plans with provider listings in each state. A Medicare Advantage plan that serves several states counts in each of them.
