More detail
Confirming a staff member's license, certification, education or board status directly with the body that issued it, rather than accepting a copy from the applicant. Health plans credentialing providers must verify through the primary source, a recognized source or a contracted agent such as a credentials verification organization (CVO), and NCQA certifies CVOs on that basis. Accreditors apply the same expectation to the treatment program's own files, so a copy of a CADC card is not enough; the file needs a dated lookup from MHACBO, the Oregon or Washington license search, DOPL or the BBS. Operators care because payer credentialing stalls when PSV is missing, and surveyors cite files that hold only self-reported credentials.
Also called primary source verification, credential verification, CVO, credentials verification organization
