Formulary & Substitution Advisor

The Formulary & Substitution Advisor integrates payer formulary and therapeutic equivalence logic directly into EMR ordering workflows. It surfaces on-formulary options, dosage guidance, and approved therapeutic alternatives at the moment of order entry, reducing prior authorization delays, cost friction, and manual review cycles.

Using CDS Hooks to intercept prescribing events and a SMART on FHIR detail view for contextual comparison, the app presents formulary coverage tiers, alternative agents, and policy-specific substitution recommendations, while preserving prescriber choice and full audit traceability.
