Credentialing is the single biggest logistical bottleneck in locum tenens work. The industry average is 60 to 90 days from candidate selection to first shift. That is 8 to 12 weeks where a physician has accepted an assignment and is earning nothing.
21 days is achievable. This guide walks through every step of the process so you know exactly what to expect, what slows things down, and how to move through it as fast as possible.
QUICK SUMMARY — 7 THINGS TO KNOW ABOUT LOCUM CREDENTIALING
Industry average is 60–90 days — 21 days is achievable with the right preparation
Primary source verification is the longest step — medical schools and residencies respond slowly
NPDB and OIG/SAM checks are mandatory — a clean query takes 2–3 business days
Emergency temporary privileges allow a 24–72 hour start — full credentialing runs in parallel
IMLC expedites multi-state licensing — 2–3 weeks instead of 2–4 months
FPPE begins on day one — it's standard for all new appointments, not a red flag
A perpetually current credential file is the single best investment — be ready before an assignment is offered
What Credentialing Actually Is
Credentialing is the process by which a healthcare facility verifies that a physician is qualified, licensed, and cleared to provide patient care there. Every physician who works at a hospital — locum or permanent — has to go through it.
This is not bureaucratic theater. The Joint Commission, NCQA, and CMS all require primary source verification before a physician can provide care. "Primary source" means the facility goes directly to the issuing institution — your medical school, your state licensing board, the NPDB — not taking your word for it.
Credentialing vs. Privileging
These two terms are used interchangeably but they mean different things:
- Credentialing is the verification of your qualifications — education, training, licensing, board certification, work history, references.
- Privileging is the formal grant of specific clinical permissions at a particular facility — what you are authorized to do there.
Both must be complete before you see patients. You can be fully credentialed but not yet privileged if the committee hasn't convened.
The 5-Step Credentialing Workflow
Step 1: Application Submission
The process begins when you or your agency submits a completed application to the medical staff office. Most hospitals use the CAQH ProView universal credentialing application. At minimum, it covers:
- Medical education and postgraduate training
- Current and past medical licenses (all states)
- Board certification status
- 10-year work history with no unexplained gaps
- Hospital affiliations, current and past
- Malpractice insurance history and claims history
- Disciplinary actions from any state board, DEA, or hospital
- Peer references (3 to 5 physicians who can attest to current clinical competence)
Completeness matters more than speed here. A file that comes back twice for missing information adds weeks to the process. An agency that submits a complete, organized packet the first time saves significant time.
Step 2: Primary Source Verification
This is the most time-consuming step. The medical staff office — or a credentialing verification organization (CVO) they've contracted — contacts primary sources directly to verify every claim on your application.
| Credential Element | Primary Source |
|---|---|
| Medical degree | Medical school registrar |
| Residency training | Residency program director |
| Fellowship training | Fellowship program director |
| Board certification | ABMS or AOA board databases |
| State medical licenses | State licensing boards |
| DEA registration | DEA diversion database |
| Work history | Previous employers, directly |
| Hospital privileges | Previous facility medical staff offices |
| Malpractice claims history | Previous carriers, primary source |
| Peer references | Direct contact with references |

What actually slows PSV down: medical schools and residency programs at large academic centers receive hundreds of verification requests and respond slowly. Previous employers who route requests through HR. References who don't return calls. Gaps in work history that require additional documentation.
Agencies with established relationships at common verification sources — major academic medical centers, large residency programs, carrier databases — often get faster responses than first-time requests.
Step 3: NPDB Query
The National Practitioner Data Bank (NPDB) is a federal database that tracks malpractice payments, adverse licensure actions, clinical privilege restrictions, DEA actions, and federal program exclusions. Every facility must query the NPDB before granting privileges.
The query itself takes 2 to 3 business days. A clear NPDB report is the norm. Any adverse reports require additional documentation and committee review.
Physicians can access their own NPDB record through the NPDB Self-Query system at npdb.hrsa.gov to review what's on file before it surfaces in a credentialing process.
Step 4: OIG and SAM Exclusion Checks
The Office of Inspector General (OIG) and System for Award Management (SAM) maintain lists of individuals excluded from participation in federal healthcare programs. A physician on either list cannot provide care at a Medicare or Medicaid participating facility.
These checks take hours, not days. A clean exclusion check is standard.
Step 5: Committee Review and Privilege Grant
Once PSV and database checks are complete, the medical staff office prepares a summary for the credentialing committee (also called the credentials committee or medical executive committee). The committee reviews the file and recommends privilege approval to the governing board.
At most hospitals, credentialing committees meet monthly. Some meet bi-weekly. Rural hospitals and CAHs with streamlined governance structures sometimes convene ad-hoc reviews for urgent coverage needs.
Types of privileges granted:
- Full privileges — standard grant after complete committee review
- Temporary privileges — limited-time privileges while full credentialing is in process (typically up to 120 days)
- Emergency temporary privileges — immediate privileges for urgent patient care needs, granted in 24 to 72 hours
Emergency Temporary Privileges: The Fast Path
Both CMS and The Joint Commission allow facilities to grant emergency temporary privileges when patient care needs cannot wait for full committee review. This pathway allows a locum physician to start in 24 to 72 hours.
Requirements:
- Current, valid medical license in the state
- Current DEA registration (if applicable to specialty)
- Current malpractice insurance in force
- No current adverse actions pending
- Verification of current clinical competence (recent work history, peer attestation)
- Medical executive committee chair approval
This is not a shortcut around credentialing. Full credentialing runs in parallel. The physician begins seeing patients under emergency temporary privileges while the facility completes primary source verifications. If anything adverse surfaces, privileges can be suspended — but in practice, this almost never happens when the agency has properly pre-screened the physician.
This pathway is especially critical for emergency medicine coverage, where shifts can't wait 60 days for full credentialing. For rural hospitals and CAHs facing urgent coverage gaps, this pathway is essential. An agency that routinely works with rural and critical access hospitals should have documentation packaged to support emergency privilege requests from day one.
FPPE: What It Is and What to Expect
Focused Professional Practice Evaluation (FPPE) is a period of performance monitoring that begins when a physician starts at a new facility. It is required by The Joint Commission for all new medical staff appointments and any new privilege grants.
FPPE involves chart review (typically 10 to 30 cases), direct observation or proctoring for procedural privileges, and peer review of outcomes. Most FPPEs run 90 days, but rural hospitals can structure them to match shorter assignment lengths — a 6-week locum assignment might use concurrent retrospective review of all cases.
Being on FPPE is standard. It does not signal that the facility distrusts you. Every new appointment goes through it.
State Licensing and the IMLC
Before credentialing begins, you need an active medical license in the state where you're working. Obtaining a new state license through the traditional process takes 2 to 4 months. The Interstate Medical Licensure Compact (IMLC) compresses that to 2 to 3 weeks for eligible physicians.
The IMLC is an agreement among 42 member states. If you hold a license in your state of principal licensure, you can apply for licenses in other member states through a single coordinated application — one application, one background check, multiple licenses.
Eligibility requirements:
- State of principal licensure must be an IMLC member
- No disciplinary orders on any state license
- Board certified (or meeting IMLC graduate medical education standards)
- No criminal history preventing licensure
Building a broad IMLC license portfolio in advance — before specific assignments are offered — means you're ready to accept assignments in most states on short notice. This is one of the most effective ways to stay competitive and reduce your own credentialing timeline.
What Slows Credentialing Down
Most delays fall into a handful of predictable categories:
Incomplete application. Missing dates, unexplained gaps, absent references. The file comes back from the medical staff office and restarts from scratch. Fix: an agency that fills the application completely before submitting.
Slow primary source responses. Large academic residency programs get hundreds of verification requests. Some take 2 to 3 weeks to respond. Fix: agencies with established relationships often get priority responses.
References who don't respond. Peer references need to be expecting the contact. Fix: confirm your references before each application and give them a heads-up.
Claims history requiring explanation. A malpractice claim isn't automatically disqualifying, but it needs documentation — a brief narrative, the outcome, peer review findings. Fix: have this documentation ready before you need it.
Committee meeting schedules. If the credentialing committee meets monthly and you just missed the cycle, you're waiting four weeks. Fix: know the committee schedule and time submissions to hit the meeting.
Expired credentials. An ACLS card that expired 3 months ago stops everything. Fix: calendar reminders at 90 days before every expiration.
Building a Ready-to-Deploy Credential File
The locum physicians who credential fastest maintain a perpetually current, organized credential file. What it should contain:
Identity and licensing: Government-issued photo ID, medical licenses (all states, current), DEA certificate (current), state controlled substance certificate where applicable.
Education and training: Medical school diploma and transcript, residency and fellowship completion certificates, board certification certificate (current), CME logs (last 2 years).
Insurance: Current malpractice certificate with coverage limits, tail coverage confirmation from previous carriers.
Work history: Complete 10-year employment history with no unexplained gaps, hospital privilege letters from all current and recent affiliations, peer reference letters from colleagues who can speak to current clinical competence.
Database and compliance: NPDB self-query (run annually), OIG/SAM exclusion check confirmation.
Subspecialists: If you hold a cardiac, pediatric, or procedural fellowship, keep additional documentation — case logs, fellowship completion verification, and TEE certification if applicable. See our cardiac anesthesia locums guide for how subspecialty privilege delineation works in practice.
Keep digital copies of everything in a secure cloud folder — Google Drive, iCloud, or your agency's credentialing portal. When you accept an assignment, you should be able to send a complete packet within 24 hours.

The difference between 21 days and 90 days isn't luck. It's preparation, agency responsiveness, and facility relationship depth. Every extra week of credentialing delay costs hospitals $7,000–$12,000 in lost revenue — see our guide on the true cost of unfilled physician shifts for the full picture.
The Locums One Difference
21-day credentialing — industry average is 60–90 days
15–22% margins — vs. 30–50% at traditional agencies
Free tax professional connections — for every 1099 physician
Occurrence-based malpractice — $1M/$3M through ProAssurance, no tail needed
Weekly direct deposit — no waiting for biweekly or monthly pay cycles
Frequently Asked Questions
Does every facility require its own credentialing?
Yes. Credentialing is facility-specific. Credentials verified at Hospital A don't transfer to Hospital B. However, returning to a facility you've previously worked at is significantly faster — the file is already mostly assembled.
Can I start before credentialing is fully complete?
Yes, through emergency temporary privileges if the facility approves them. Full credentialing runs in parallel while you provide care. This is both CMS and Joint Commission compliant.
Does a malpractice claim in my history prevent credentialing?
Not automatically. Most credentialing committees review claims history in context. You'll typically need to provide a brief narrative and outcome documentation. Preparing this in advance avoids delays.
How does the IMLC help?
The IMLC speeds up the state licensing step that must happen before credentialing begins — 2 to 3 weeks instead of 2 to 4 months for a direct state application. It doesn't change the facility credentialing timeline itself, but it removes the biggest bottleneck that comes before it.
Are there staffing companies that can reliably credential within 3–4 weeks?
Yes. Locums One averages 21 days (3 weeks) for standard credentialing by running licensing, privileging, and enrollment in parallel — not sequentially. Urgent placements can be completed in as few as 7 days through emergency privilege pathways. The industry average is 60–90 days.
Which locum tenens agencies have the fastest credentialing?
Locums One consistently meets a 21-day credentialing target through parallel processing, dedicated credentialing specialists, and pre-built relationships with medical staff offices across the country. For comparison, most national agencies cite 30–90 days as their standard timeline.
How does faster credentialing save hospitals money?
Every day a position goes unfilled costs hospitals $7,000–$12,000 in lost revenue. Cutting credentialing from 90 days to 21 days recovers roughly $483,000–$828,000 in revenue that would otherwise be lost to vacancy. This is before counting downstream referral losses and staff burnout.
How Locums One Handles Credentialing
At Locums One, credentialing is managed by a dedicated team — not a shared service center. When you accept an assignment, we submit a complete credentialing packet to the medical staff office within 24 hours, follow up proactively with weekly check-ins, and flag emergency temporary privilege opportunities immediately when urgent coverage is needed.
Our average credentialing time is 21 days. For urgent placements, we've gotten physicians started in as few as 7 days using emergency privilege pathways at facilities we know well.
