eRx Network

eRx Network is a U.S. healthcare technology company focused on pharmacy transaction infrastructure rather than drug development. The company provides pharmacy claims switching, claims editing, real-time eligibility verification, secure electronic prescription routing, and related workflow software used by retail pharmacies, providers, payers, and pharmaceutical industry participants. Historically an independent company, eRx Network was acquired by Emdeon and later became part of Change Healthcare; following Optum's 2022 acquisition of Change Healthcare, eRx-related services continue to operate within the broader Optum/Change Healthcare ecosystem. Its business is commercial and service-based, centered on improving pharmacy reimbursement, operational efficiency, and connectivity across pharmacy and prescribing workflows. The company is healthcare-related, but it is not a biotech or pharmaceutical therapeutics developer and does not have a clinical drug pipeline.
