MD-Staff vs Medallion (2026)
Software your team runs against a service that runs it for you. MD-Staff, from Applied Statistics and Management, a family owned company founded in 1982, is the credentialing, privileging, enrollment and peer review platform a medical staff office operates itself, sold as modules, with more than 3,000 client organizations reported and a number one KLAS ranking for credentialing. Its Aiva engine verifies against issuing organizations, gathers documents, sends reminders, summarizes provider histories and flags files with potential issues. Medallion runs provider network operations as a managed service through its own NCQA certified credentials verification organization, publishes which tasks its agents do and what sends a case to a specialist, backs turnaround and a 99.9 percent file accuracy figure with contractual commitments, and acquired Andros in September 2026. If your failure mode is keeping the work in house on an established system, start with MD-Staff. If it is getting the work done under contract, start with Medallion.
- It is the system of record a medical staff office runs itself, covering credentialing, privileging through E-Priv, enrollment, peer review and committee tooling, sold as modules.
- Aiva runs verification directly against issuing organizations, including the American Medical Association and state licensing boards, and summarizes provider histories for committee review.
- It scales from a single clinic to a large state health system, with more than 3,000 client organizations reported and a number one KLAS ranking for credentialing.
- The work is done for you by a certified credentials verification organization, across credentialing, payer enrollment, rosters, delegated credentialing, privileging, cross state licensing and monitoring.
- The split between agents and people is published. Agents extract data, fill profiles, submit enrollments and chase stalled providers, while credentialing specialists take flagged exceptions and review every critical stage.
- Commitments come with contract, with guaranteed turnaround times and 99.9 percent average file accuracy, and the help center names SOC 2 Type II with a trust center.

MD-Staff's pages say its verification ensures all credentialing information is accurate and up to date and that its algorithms guarantee compliance, and nothing published measures any of it: no accuracy figure, no turnaround at a named customer and no named customer at all. It publishes no security attestation and no document addressing health information, and it is a software vendor rather than an accredited verification organization. Medallion's 99.9 percent figure is a contractual commitment whose definition and remedy are not published, and Medallion publishes no business associate terms. Neither publishes a price.
