Secure, real-time EOI decisioning on a benefit technology partner's platform when required by an elected Guardian benefit. Employees required to submit EOI are presented the required health questions during their benefit shopping experience and receive instant notification of approval or referral to underwriting. Where underwriting review is required, the partner can call Guardian's system for EOI transaction status updates.
