Choose the right perspective
Ask whether the person's work covered hospital privileging, payer enrollment or both, since medical staff offices and enrollment teams follow different rules and timelines. Also ask whether the person has run a centralized credentials verification organization for a multi-hospital system, because consolidating credentialing across facilities raises its own staffing and accreditation questions.
Questions to take into the conversation
- 01Which steps in credentialing and payer enrollment cause the most delay for a new physician, and how do you shorten them?
- 02How do you keep a credentialing program ready for Joint Commission and NCQA review at the same time?
- 03When does it make sense to centralize credentialing for several hospitals into one verification office?
