 Statewideness refers to a requirement that the managed care program must be operational statewide.
 Comparability refers to a requirement that benefits for managed care enrollees must be equivalent to fee-for-service benefits.
 Freedom of choice refers to enrollees’ ability to receive services from any qualified provider; waiving this requirement requires enrollment in a managed care program and limits choice of providers to those in the health plan’s network.
