HealthChoice Illinois covers urgent care billing for eligible Illinois beneficiaries, delivering most of that benefit through managed care organizations with a remaining fee-for-service population.

Across Naperville's 40 organizations, even a few percentage points of MCO-routing error compounds into material rework.
