The contract is signed. The locum is booked. The service line has been waiting for weeks. Then the start date slips, and slips again, because a reference hasn't come back or a license verification is stuck in someone's inbox. Provider credentialing delays commonly run 90 to 120 days [TechTarget].
Most physician recruitment leaders know this story by heart. What gets less attention is how much of that time is avoidable. Locum tenens credentialing is detailed work, and it should be. But a large share of the wait comes from documents collected twice, files passed between agencies and medical staff offices, and nobody owning the clock.
This guide walks through where the time goes, what credentialing delays really cost, and how to shorten the timeline without cutting a single corner on patient safety.
Every locum physician or advanced practitioner has to clear the same core checks before they can see patients. At a minimum, that usually means:
None of these steps is optional. The delays come from how they're handled. The agency builds a credentialing file. The hospital builds its own. Documents get requested twice, verifications run one after another instead of side by side, and a missing signature can hold up an entire file for a week before anyone notices.
You'll often see a striking number attached to credentialing delays: up to $122,144 lost per physician over a 120-day delay. It's worth knowing where that comes from. The figure is from an Assured analysis, and it's based on the average physician salary of $239,200 from Bureau of Labor Statistics data. In other words, it measures what the physician loses in earnings while they wait [TechTarget].
For the hospital, the math is usually bigger. Merritt Hawkins' 2019 revenue survey found that physicians generate an average of about $2.4 million a year for their affiliated hospitals [Healthcare Dive]. Divide that by 365 and each open day works out to roughly $6,500 in revenue a physician would otherwise help bring in. Your number will vary by specialty and setting, but the direction is clear: every day a locum waits is a day of care and revenue the organization doesn't get back.
And revenue is only part of it. While a start date slides, the rest of the team absorbs the gap through extra call, longer clinic days, and deferred cases. That's how credentialing delays turn into burnout and turnover, which cost far more than the original vacancy.
Here's where a typical file tends to stall, and what usually causes it.
| Stage | What happens | Common cause of delay |
|---|---|---|
| Document collection | Provider and agency submit the application packet | Missing or outdated documents, requested more than once |
| Verification | Licensure, education, training, NPDB and exclusion checks | Checks run one at a time instead of in parallel |
| References | Peers confirm clinical competence | Slow responses, no follow-up owner |
| Committee review | Chair, credentials committee, MEC, governing body | Files miss the meeting cycle and wait for the next one |
| Payer enrollment | Enrollment with Medicare, Medicaid and commercial plans | Started only after privileging is approved |
| Onboarding | EHR access, orientation, badge, scheduling | IT and department tasks kicked off too late |
Notice the pattern. Very few delays come from the verification itself. Most come from handoffs, waiting, and work that starts later than it could.
Credentialing shouldn't begin when a provider is selected. Attach the credentialing requirements to the requisition itself, so every candidate arrives with the right documents from day one.
If each agency submits files in its own format, your medical staff office spends its time translating. Give every vendor the same specialty-specific checklist and the same submission standard.
Many locums return to the same facility or system. Keep their verified documents in one place so a returning provider isn't starting from zero, and so the file only needs updating, not rebuilding.
License, board, education, NPDB and exclusion checks don't depend on each other. Launch them together, and send reference requests on day one instead of day ten.
The Joint Commission allows temporary privileges in two situations: to fulfill an important patient care, treatment, and service need, or when an applicant with a complete application that raises no concerns is awaiting final approval. For new applicants, those temporary privileges are granted for no more than 120 days [The Joint Commission]. The expedited governing body approval process under standard MS.06.01.11 can also shorten the wait for clean files. Use these tools as designed, not as a workaround. As Credentialing Resource Center puts it, "the overuse of temporary privileges has long been considered a red flag" during surveys [Credentialing Resource Center].
Payer enrollment can add weeks if it starts after privileging. Loop in your revenue cycle team at the requisition stage. When a locum is covering for an absent physician, Medicare's fee-for-time rules let the regular physician bill the substitute's services with modifier Q6 for up to 60 continuous days [Noridian Medicare]. Confirm with your billing team which arrangement applies before the start date.
What gets measured gets faster. Track days from offer to approved privileges, and days from approval to first shift, for every file and every agency. Within a quarter you'll know which partners submit clean files and which ones stall.
Approved privileges don't mean a locum can work tomorrow. EHR access, orientation schedules, parking, badges, and department introductions all take time. The fastest programs treat the physician onboarding process as a parallel track that starts while credentialing is still underway, so the last approval signature is also the last step before the first shift.
Credentialing delays are rarely a people problem. They're a visibility problem. When files live in email threads, agency portals, and spreadsheets, nobody can see which one is stuck or why. Ringo puts every file, every document, and every deadline in one place.
The result is a locum program where the start date on the contract is the start date that actually happens. For more on the operational side, see why most hospitals still manage locum tenens with spreadsheets and what locum tenens coverage really costs.
Locum tenens credentialing will always take real work, and it should. Patient safety depends on it. But most of the time lost between a signed contract and a first shift comes from duplicate documents, sequential steps, and files nobody is watching.
Start credentialing at the requisition. Give every vendor the same standard. Run checks in parallel, use expedited pathways correctly, and measure every file. Each day you take out of the timeline is a day of coverage your patients and your team get back.
Ringo is the leading vendor-neutral workforce management platform purpose-built for healthcare, managing locum tenens, nursing, allied health, APP, and nonclinical staffing in one place with no agency affiliations. Ringo earned a 94.2 overall satisfaction score in the KLAS 2025 First Look Report, with 100% of interviewed customers saying they would buy again.
Provider credentialing commonly takes 90 to 120 days, and incomplete files can push it longer. The timeline depends on how quickly documents are collected, how fast verifications and references come back, and when committee and governing body meetings fall.
It depends on the specialty and setting. An often-cited Assured estimate of up to $122,144 over 120 days reflects the physician's lost earnings. For hospitals, Merritt Hawkins' 2019 survey found physicians generate about $2.4 million a year on average, or roughly $6,500 a day. Unfilled days also add overtime, extra call, and burnout for the rest of the team.
Yes, within limits. The Joint Commission allows temporary privileges to meet an important patient care need, or for a new applicant with a complete, clean application awaiting final approval. For new applicants, temporary privileges are granted for no more than 120 days. They should be used as designed, not as a routine shortcut.
Attach credentialing requirements to the requisition, give every vendor the same checklist, reuse verified documents for returning providers, run verifications in parallel, start payer enrollment and onboarding early, and track time to credential by vendor. A single platform for all of it removes most of the handoffs that cause delays.
FROM SIGNED CONTRACT TO FIRST SHIFT
Your locum is ready. Is the paperwork?
Picture the file for your next anesthesiologist. The agency uploads the credentialing package the moment they submit the candidate. Your medical staff office sees exactly what's verified, what's missing, and what expires next month. References go out on day one. Nobody has to ask for the DEA certificate twice.
That's how Ringo works. Credentialing, onboarding, scheduling, and billing live on one vendor-neutral platform, so every agency submits to the same standard and every file is visible from submission to first shift. Because Ringo owns no staffing agency, every supplier competes fairly, including on how fast they deliver a clean, complete file.
Fewer stalled files. Faster start dates. A recruitment team that can finally show exactly where the days went, and how many it got back. It's part of why Ringo earned a 94.2 overall satisfaction score in the KLAS 2025 First Look Report.
