The protocol is the source document for every billing decision, but reading it for billing purposes takes a different lens than reading it for operations. This session walks through a protocol section by section to identify qualifying criteria, standard-of-care versus research-only procedures, screen failure handling, unscheduled visits, and hidden cost drivers. We will cover the specific language cues that signal a billing designation and the questions to send back to the sponsor when the protocol is silent. Attendees will see how a careful protocol read prevents rework in the budget, consent form, and study calendar. Ideal for anyone new to coverage analysis or looking to sharpen an existing process.
