Why locum tenens credentialing starts over at every facility

A locum hospitalist is due to start on the first Monday of the month. His state license is active, and the signed contract and the malpractice certificate are both in the file. The medical staff office has everything it needs except one item: a written response from the residency program that trained him. The coordinator has chased it three times. The credentials committee meets on the second Tuesday, the governing body two weeks after that. He will not start on the first Monday, and the hospital will cover those shifts some other way.

That is the ordinary shape of locum tenens credentialing, and travel nurse credentialing behaves the same way. He was fully credentialed at another facility ten weeks earlier, and the same residency verification is sitting in that file. None of it helps here. The reason sits in the federal condition of participation and in the verification standards the profession works to, upstream of anything the receiving medical staff office controls.

What a multistate license does not do for the receiving facility

Licensure is a state's authority to practice a profession within its borders. Privileges are one facility's decision about what a named individual may do inside its walls, granted by that facility's governing body.

Nurse licensure has real cross-border portability. The Nurse Licensure Compact map published by the compact itself records 43 jurisdictions that have enacted the NLC, of which 40 carry an implementation date. Massachusetts and the U.S. Virgin Islands remain pending, and Guam sits at partial implementation.

Physicians have an expedited licensure pathway through an interstate compact of their own, which shortens the time to a license in another state without changing what a license is. A travel nurse with a multistate license can lawfully work in the next state on the day she arrives, and still cannot see a patient until the facility's own process has run. The hospitalist waiting on his first Monday already holds an active license in the state he is standing in.

Where the credentialing decision sits under 42 CFR 482.22

The Medicare condition of participation puts both the appraisal and the appointment inside the individual hospital. Under 42 CFR 482.22 the medical staff must examine the credentials of all eligible candidates for membership and make recommendations to the governing body on their appointment, and must periodically conduct appraisals of its members. The governing body holds the appointment authority.

Two consequences follow. The decision cannot be delegated to a licensing state or a staffing partner, because the rule names the governing body of the hospital where the care will be delivered. The rule also sets no numeric interval for appraisal; it says "periodically". The three-year privileging period belongs to the Joint Commission and the 36-month recredentialing cycle to NCQA, so a policy manual that attributes either to CMS is citing the wrong authority. Nothing in the rule gives a medical staff office a route around the committee for a clinician due to start before it meets.

Credentialing by proxy exists, and only for telemedicine

One place in the regulation lets a hospital rely on someone else's credentialing and privileging decision. Under 482.22(a)(3) a hospital may accept the decisions of a distant-site Medicare-participating hospital, and under (a)(4) those of a distant-site telemedicine entity. Both require a written agreement and a current list of the practitioner's privileges. The provisions were introduced in the Federal Register rule of May 5, 2011.

That exception states the general rule more clearly than anything else. CMS built a reliance mechanism and confined it to telemedicine. A travel nurse on a med-surg floor and a locum physician covering a colleague's leave both fall outside it.

180 days, and why another facility's file counts as a secondary source

The NAMSS Ideal Credentialing Standards for Initial Practitioner Applicants, January 2024 edition, instruct that medical services professionals "should primary-source verify all information to support the following 13 criteria within 180 days prior to the credentialing decision". They run from proof of identity and education through licensure, board certification, practice history, the National Practitioner Data Bank query and peer references.

The same document is explicit about what a file from elsewhere is worth. Credential verification obtained from another facility is a secondary source, for use only where the primary source no longer exists, and unacceptable for many data elements.

Together they explain why locum tenens credentialing repeats. The hospitalist's file from his last assignment is recent, complete and correctly verified, and it fails on both counts at once. It is the wrong kind of source, and the verifications inside it sit on a clock that runs to 180 days from the next decision rather than the last one. NAMSS also records that staffing and locum tenens companies may perform credentialing, which settles who may run a verification and leaves untouched whose decision a receiving facility may rely on.

Where locum tenens credentialing time actually goes

The sequence is longer than the verification. In the process description the American Medical Association published with NAMSS in November 2019, the file passes from the medical services professional to the department chair, the credentials committee, the medical executive committee and the governing body. Committees meet on a calendar the file does not control.

The same material names where delay concentrates: incomplete documentation, overlooked releases, ancillary documents and, above all, obtaining appropriate responses from authoritative sources. Work history, peer references and malpractice carrier verification are the hardest to close.

Line those causes up against the NAMSS 13 and the problem becomes countable. Four of the criteria depend on somebody else writing back: education and training, the practice history timeline, malpractice carrier verification and peer references. The other nine resolve against a register, a database or a document the applicant holds, and close when the work is done. The four close when a third party replies, so the only lever anyone has on them is the day they were sent.

What can be made portable: the candidate's side of the file

The verification decision cannot be inherited. The raw material behind it can be collected once and reused indefinitely, and that distinction is where the recoverable time in locum tenens credentialing sits.

A diploma has no expiration date. Neither does a residency completion date, a DEA number or an employment history timeline. What expires is the verification. When the hospitalist retypes the same eight years of practice history into another facility's PDF form, those keystrokes produce no verification at all.

For the clinician, the good version is short. He photographs his DEA registration and his immunization record on his phone between shifts, without downloading anything, and the documents are classified and the data pulled out of them automatically. His practice history is parsed from the resume already on file, so the next assignment asks only for what is new to it. Credentially, in this market since 2017, configures the workflow behind the portal per role. Expiration dates are monitored on a daily cycle and flagged before they lapse.

The same assignment, with the transcription removed

Change nothing about 42 CFR 482.22 or the committee calendar. Change only what the staffing firm and the medical staff office control between them.

His identity documents, education dates, license number, DEA registration and eight-year practice history are collected once and held as a record. The receiving facility still verifies every one of them from the primary source. The record removes only the re-entry.

The four that wait on a reply move the date. Primary source verifications are initiated automatically against the source, so a coordinator's list stops deciding when a request goes out. Sent with reminders on the day his application opens, the residency verification and the peer reference requests run alongside the other nine. The primary source verification overview and the compliance monitoring detail set out what Credentially checks and against which source.

The residency office still takes as long as it takes. What moved is the day it was asked. His file stalled on one of the four because that request went out after the other nine had closed.

The credentials committee still meets on the second Tuesday and the governing body two weeks after that. The one thing a receiving facility controls is whether a file reaches that agenda or the one after it, and on a monthly cycle the gap between them is a month of cover somebody has to find.

What genuine portability would require

A verified file could only travel with a clinician if two separate things changed.

The first is the reliance rule. 42 CFR 482.22 permits a governing body to accept another organization's decisions only for telemedicine, under a written agreement. Extending that to on-site contract clinicians means answering who carries the liability when a privileging decision made in another state turns out to have been wrong. That is a question for CMS and hospital boards, and no vendor settles it.

The second is the status of the verification itself. While another facility's verification remains a secondary source under the NAMSS standards, and while the checks behind it lapse at 180 days, a receiving organization has no defensible basis for inheriting them. Nothing on the accreditation agenda proposes changing either.

Neither change is close. What a receiving facility and a staffing firm can settle between them is everything in locum tenens credentialing that was never verification: requests for documents the clinician has already supplied, and the days a complete file spends queuing for a committee that could have received it on day one. The hospitalist's first Monday was decided in the week his application opened.
