Yes, RenConnect is designed to plug into the systems employers and brokers already rely on, rather than forcing them into a single rigid format. It supports standard and custom eligibility data connections — including EDI 834, Employee Navigator XML, and flat files like .csv, .xls, and .xlsx — so eligibility and enrollment data can flow cleanly into Renaissance systems, helping keep eligibility, billing and claims aligned and reducing re-keying and reconciliation work.
