Both approaches can return specific benefit details. The difference is cost structure and consistency. Every call has a duration and a price, and two representatives at the same payer will answer the same question differently on the same day. Data-first tools need upfront configuration, fee schedules and a stack of representative EOBs, before they are useful, which is the trade-off.
Few vendors say where they sit. Veribrance completes more than 95% of verifications without a payer call. When you evaluate a tool, ask for that number and whether it is going up or down for existing customers.
