Credentialing

What gets verified

The scope depends on the role. For physicians and advanced practice providers it is extensive; for allied and support staff it is lighter but still strict.

• Licenses: state license, status, expiration date and any disciplinary actions. For nurses, multistate compact licenses also need checking.
• Education and training: medical or nursing school, residency, fellowship.
• Board certification where relevant.
• Certifications: BLS, ACLS, PALS, CNA, phlebotomy, pharmacy technician and others.
• Work history with explanations for gaps, often through employment verification.
• Malpractice history and claims, and for physicians, a query to the National Practitioner Data Bank.
• Exclusion and sanction lists, including the HHS Office of Inspector General exclusion list and the federal System for Award Management. Employing an excluded person in work paid by federal health programs can lead to penalties.
• Health requirements: immunizations, TB screening, sometimes drug testing, alongside a background check.

Primary source verification

Primary source verification means confirming a credential with the organization that issued it (the state board, the school, the certifying body) rather than accepting a copy from the candidate. A photocopy of a license proves nothing on its own; licenses get suspended, and documents get altered.

Accrediting bodies such as The Joint Commission and NCQA set standards for what must be verified and how. NCQA standards, for example, call for recredentialing of practitioners at least every 36 months. Licenses and certifications with shorter expiry cycles must be tracked continuously, not just at hire.

Credentialing vs privileging vs enrollment

These terms get mixed up:

• Credentialing: verifying qualifications.
• Privileging: a hospital's decision about which specific procedures a credentialed practitioner may perform there.
• Payer enrollment: getting a provider set up with insurers and Medicare or Medicaid so their services can be billed. It depends on credentialing but is a separate process with its own delays.

For non-clinical support hires (patient access, medical billing, unit clerks), credentialing usually means a lighter set of checks: identity, background, exclusion lists and any required certification.

Timelines

Typical ranges: two to five business days for a nurse, CNA or allied health worker with clean records and online license lookups; 60 to 120 days for a physician joining a hospital medical staff, including committee review and privileging; longer when payer enrollment is needed before the provider can bill.

A worked example: a health system staffing agency places 40 travel nurses a month. Its median credentialing time is nine days, mostly waiting for candidates to upload BLS cards and immunization records. Collecting documents during the interview stage, and checking state boards and exclusion lists the day an offer is accepted, brings it to four days and gets nurses on shifts a week earlier. The same approach applies to locum tenens physicians, where every day of delay is lost revenue.

Common mistakes

• Accepting copies instead of verifying with the source.
• Checking exclusion lists only at hire. Many organizations check monthly, since the OIG list is updated monthly.
• Not tracking expiry dates for licenses and certifications, then discovering a lapsed BLS card during an audit.
• Starting credentialing only after the offer is signed. Collect documents early.
• Treating staffing agency credentialing as a substitute for your own obligations. Contracts usually split responsibilities; audit the agency's files.
