The EPCS 2.0 Act requires health insurance plans and insurers to implement electronic prescribing for controlled substances starting January 1, 2025. The requirement applies to prescriptions for Schedule II through V controlled drugs covered by group health plans, individual health insurance, and employer-sponsored plans. The bill includes exceptions for situations like hospice care, nursing facility residents, technology failures, and public health emergencies, and it prohibits insurance plans from penalizing pharmacies or denying claims based on how prescriptions are submitted. The legislation also preserves patient choice in pharmacy selection and prevents insurers from burdening pharmacies with excessive verification requirements beyond normal prescription processing.
