A credentials verification organization (CVO) independently confirms that a clinician’s credentials are genuine, current, and documented — going to the issuing board, school, registry, or employer rather than accepting the clinician’s copy. That process is primary source verification, the backbone of every credentialing file you will be asked to defend. AMS Solutions delivers CVO services to healthcare staffing agencies: primary source verification at intake, expirables tracking across every assignment, facility privileging support, and ongoing exclusion monitoring. We have worked in healthcare administration since 1992, and every verification is performed by U.S.-Based Specialists. Request a scoped quote below, or call 866-973-2221.
Built for Healthcare Staffing Agencies
Most CVO credentialing companies were built to serve health plans and medical groups. We built this one for the agency side — organizations that must produce a complete, defensible file on a compressed timeline, for a clinician recruited nine days ago, for a facility that will audit it. We serve:
- Locum tenens agencies placing physicians, CRNAs, and advanced practice providers into short-term coverage across several states at once.
- Travel nursing agencies running 13-week cycles where a credentialing delay is a lost placement, not a scheduling problem.
- Allied health staffing firms placing therapists, imaging technologists, laboratory personnel, surgical techs, and respiratory therapists whose certifications vary by discipline and facility.
- Per diem and float pool programs where one clinician may work at four facilities under four different file requirements.
We are the verification engine behind your recruiters and compliance team: you decide who to place, we make sure the file holds up when someone outside your organization reads it.
What We Verify
Our scope is built against the eleven credentialing evaluation areas that define the industry standard for CVO certification — License to Practice; DEA or CDS Certification; Education and Training; Board Certification Status; Work History; Malpractice Claims History; State Licensing Board Sanctions; Medicare/Medicaid Sanctions; Practitioner Application Processing; Application and Attestation Content; and Ongoing Monitoring of Sanctions. AMS is not an NCQA-certified CVO; we treat that eleven-area framework as the benchmark our files are built to satisfy.
Licensure and Multistate Practice Authority
We verify licensure with the issuing state board and capture status, expiration, and any board action. For nursing placements, we confirm whether a license carries multistate privileges. More than 40 jurisdictions participate in the Nurse Licensure Compact; California, New York, and Illinois are not among them — so single-state planning is part of assignment feasibility, not an afterthought.
DEA and Controlled Substance Registration
For prescribing clinicians we verify DEA registration, including registered address, schedules, and expiration date. DEA practitioner registration carries a three-year period under 21 CFR 1301.13; state controlled substance registrations run on separate clocks. Both go into the expirables calendar.
Education, Training, and Board Certification
Medical and nursing school, residency, fellowship, and discipline-specific training, verified with the institution. Board certification is verified with the certifying body and re-checked at renewal.
Work History and Malpractice Claims History
A documented work history with gaps identified and explained rather than quietly passed over, plus malpractice claims history — where an incomplete file most often draws a facility’s objection.
Sanctions, Exclusions, and NPDB Queries
State licensing board sanctions, Medicare and Medicaid sanctions, and OIG List of Excluded Individuals/Entities screening, plus National Practitioner Data Bank queries and Continuous Query enrollment where required.
Job-Appropriate Credentials, Competency, and Background Screening
BLS/ACLS/PALS and discipline-specific certifications, evidence of current competency, health and immunization records where the facility requires them, and background check completion — assembled so each file contains what a reviewer looks for.
Why Agency Credentialing Is Different
If you have bought credentialing before, you probably bought payer enrollment — getting a physician contracted with commercial plans, Medicare, and Medicaid. AMS has done that for practices for decades. It is the wrong shape for a staffing agency.
Payer enrollment is a slow, application-driven process measured in health plan turnaround times: the CAQH Provider Data Portal (formerly CAQH ProView), where providers are prompted to review and attest every 120 days; Medicare revalidation every five years, or every three years for DMEPOS suppliers; health plans that commonly recredential on a three-year cycle. The provider is enrolled once, at one practice, under one tax ID.
Agency credentialing inverts all of that:
- The clock is days, not months. A file that clears in six weeks has already cost you the assignment.
- The clinician is mobile. One traveler may hold licenses in five states and work at three facilities in a year, each with its own requirements.
- The requirements come from facilities, not payers. Your client hospital’s medical staff office decides what the file must contain, and no two clients ask for the same thing.
- Volume turns over constantly. Practice credentialing manages a stable roster. You re-verify, re-onboard, and offboard continuously.
- The file has to travel. It is read by people who did not build it, under audit conditions, months after the placement started.
That last point matters most to whoever is accountable for compliance. Practice credentialing produces an enrollment outcome; agency credentialing produces evidence, and evidence has to be legible to a stranger. Every verification we complete is recorded with the source, date, method, and verifier.
Joint Commission Health Care Staffing Services Certification Support
Joint Commission Health Care Staffing Services (HCSS) certification is not a federal requirement; some states and payers recognize it, and some client health systems require it contractually. For agencies pursuing or maintaining it, the credentialing file is the center of gravity.
Certification runs on a two-year cycle, and reviews are announced. For an initial review, you will receive thirty days advance notice of your review dates; for recertification, notice comes seven business days prior to the first day of the scheduled review dates. An intra-cycle evaluation conference call falls as close as possible to the one year mid-point of the current two year certification cycle.
The file review is substantial: a minimum of 20 clinical staff personnel files will be reviewed per day, and reviewers select and examine a minimum of ten credentials files that cross the specialties within the discipline of licensed independent practitioners.
Two standardized measures speak directly to this work. HCSS-6, Completeness of Personnel File – Per Diem, and HCSS-7, Completeness of Personnel File – Travel, measure the proportion of clinical placements whose personnel file contains all three of: Job Appropriate Credentials, Evidence of Current Competency, and Background Check. We structure files so all three are present and locatable, and we support your reporting: quarterly reporting of standardized performance measure data no later than 45 days following the end of the calendar quarter is a requirement to maintain certification, with monthly data points for each standardized HCSS measure.
Delegation is explicitly contemplated. The Joint Commission states that the Joint Commission certified staffing firm must complete the credentialing process for all clinical staff that are assigned in the field, and that the hospital that contracts with the certified staffing firm may use the credentialing process of the staffing firm, and should have confidence in the completeness, accuracy, and timeliness of the information. Confidence is earned through documentation, and documentation is what we produce.
Ongoing Monitoring and Expirables Management
A credentialing file is accurate the day it is built and decaying the day after. Licenses lapse, certifications expire, DEA registrations come due, and a clinician clear at intake can appear on an exclusion list mid-assignment.
We maintain a live expirables calendar for every clinician you place — licenses, DEA and state controlled substance registrations, board certifications, BLS/ACLS/PALS, immunization and health requirements, facility-specific items — with tiered advance notice, so recruiters act before an assignment is interrupted.
On exclusions, we follow OIG’s stated best practice for limiting liability: OIG advises that because it updates the LEIE monthly, screening employees and contractors each month best minimizes potential overpayment and CMP liability. We screen on that cadence and document every screening.
OIG’s example is the staffing scenario: if a hospital contracts with a staffing agency for temporary or per diem nurses, the hospital will be subject to overpayment liability and may be subject to CMP liability if an excluded nurse from that staffing agency furnishes items or services. OIG is equally clear about where the exposure lands: because it is the provider’s responsibility to determine whether employees are excluded, the providers will retain the potential CMP liability if they employ or contract with an excluded person. Documented monthly screening is how you prove to a client facility that you take that seriously — increasingly, it is what their contracting teams ask for in writing.
Compliance and Data Security
Credentialing files hold licensure records, screening results, health information, and malpractice history. AMS Solutions maintains HIPAA compliance and holds AAPC credentials, and all verification work is performed by U.S.-based specialists.
Access is role-based and limited to the staff on your account, and files are retained so they can be reconstructed after an assignment ends. When a client facility or a reviewer asks how a credential was verified, the answer is in the record, not in someone’s memory.
Frequently Asked Questions
What is a credentials verification organization, and what does a CVO do?
A credentials verification organization is a specialized third party that performs primary source verification of clinician credentials for another entity — a health plan, a hospital, or, in our case, a healthcare staffing agency. CVO credentialing delegates that work to a dedicated team with established source relationships and documented procedures; accountability for placement decisions stays with you.
What does primary source verification actually mean?
The credential is confirmed with the organization that issued it: a license with the state board, not from a scanned copy; a degree with the school; board certification with the certifying body. Anything short of that is document collection, and document collection is what auditors find deficient.
How often should we screen clinicians for exclusions?
OIG advises that because it updates the LEIE monthly, screening employees and contractors each month best minimizes potential overpayment and CMP liability. We screen monthly and retain the documentation your clients will ask for.
Do you also handle payer enrollment for medical practices?
Yes — a separate, long-standing AMS service line covering payer enrollment, CAQH Provider Data Portal maintenance, and revalidations for physician practices. The CVO services on this page are the agency-side offering; if you run both a staffing operation and an owned clinic, we can scope both.
Do you support locum tenens credentialing and multistate travel assignments?
Yes. Locum tenens credentialing, multistate travel nursing, allied health, and per diem placements are all in scope. We track licensure by jurisdiction, manage facility-specific privileging packets, and keep expirables current across concurrent assignments.
Do you query the National Practitioner Data Bank?
Yes, where your program or client facility requires it. There is no cost to register with the NPDB and no cost for reporting to it; there is a per-query fee, and Continuous Query carries an annual per-practitioner enrollment fee. We run the queries and fold the results into the file.
