What Does a Locum Tenens Agency Actually Do? (Behind the Scenes)

The hospital administrator called me on a Tuesday at 4:47 PM. Their hospitalist had just given two weeks’ notice — effective immediately, given a family emergency — and she had a 200-bed facility, a packed schedule, and zero coverage starting Monday. She’d heard the term “locum tenens agency” from a colleague but had no idea what that actually meant in practice. “Do they just send me a list of doctors? Do I just… pick one?”

I spent the next hour walking her through how the whole thing works. This article is a cleaner version of that conversation.

The Short Version:

A locum tenens agency recruits temporary physicians and advanced practice providers, matches them to facilities with staffing gaps, handles all the credentialing and logistics, and covers malpractice insurance — so you get a qualified provider on-site without managing any of the back-office chaos yourself. Think of them as a specialized staffing firm that speaks fluent medical licensing.

Key Takeaways

• Agencies handle credentialing, licensing, travel, housing, and malpractice — you focus on clinical coverage
• The model has existed since 1979, when Dr. Therus Kolff created it specifically for rural gaps; it now serves urban systems too
• Providers work as independent contractors, paid at higher hourly rates than permanent staff because there are no benefits to fund
• Assignments run from a single shift to 3+ months — the timeline is defined by your need, not the agency’s preference

The Villain: Staffing Gaps Nobody Planned For

Here’s the scenario nobody prepares for until it’s already happening: a physician takes emergency leave, a rural clinic has been posting the same open position for eight months, a hospital hits a seasonal volume spike and suddenly needs two extra intensivists for six weeks. Permanent hiring takes months. Per diem float pools only go so far. The gap is real, the patients are real, and the clock is running.

That’s the problem a locum tenens agency exists to solve. Not hypothetically — it’s been solving it since 1979.

What the Agency Actually Does (Step by Step)

Most people think the agency “finds a doctor.” That’s like saying a general contractor “finds a hammer.” It undersells about 80% of what’s happening behind the scenes.

Step 1: You describe the need. You tell the agency your specialty, coverage dates, shift structure, and facility type. They assign you a dedicated consultant — not a call center, a named human who owns your account.

Step 2: The agency recruits and screens. They maintain networks of physicians and APPs who’ve opted into locum work. Every provider has submitted a CV, active licenses, board certification, and references. The agency verifies all of it before a name ever reaches you.

Step 3: Matching. This is where good agencies separate from mediocre ones. The consultant isn’t just looking for “a hospitalist.” They’re matching based on your facility’s culture, your geographic location, the specific shift structure, and the provider’s stated preferences. A provider who only wants Pacific Northwest assignments and 7-on/7-off schedules shouldn’t be pitched a two-week Florida rotation — and at a real agency, they won’t be.

Step 4: Credentialing and licensing. This is the invisible heavy lift. Getting a physician credentialed at your facility and licensed in your state involves primary source verification, DEA registration, state medical board applications, hospital privilege applications, and a stack of paperwork that typically takes weeks. The agency manages that process. You review the completed packet.

Step 5: Logistics. Flights, rental car or mileage reimbursement, housing or a housing stipend — the agency arranges and pays for all of it. The provider shows up. You don’t manage a travel itinerary.

Step 6: Malpractice coverage. The agency provides occurrence or claims-made malpractice insurance for the assignment. You’re not adding a temporary provider to your policy. That coverage exists independently, for that assignment, handled by the agency.

Step 7: On-site delivery. The provider shows up and does the job — full patient care, call coverage, chart documentation, staff collaboration. They integrate into your clinical workflow. They’re temporary, but they’re not visitors.

Reality Check:

Agencies don’t “supervise” the provider’s clinical work once they’re on-site. That’s your facility’s responsibility. What the agency manages is everything outside the exam room — the paperwork, the logistics, the insurance, the compliance. The medicine is still medicine.

What This Costs (And How the Model Works)

Providers working locum tenens are independent contractors. They don’t get a 401(k), health insurance, or PTO through the agency. In exchange, they command higher hourly rates than permanent equivalents — that differential is the compensation for benefits they’re self-funding.

Facilities pay the agency a bill rate that covers the provider’s compensation plus the agency’s margin (which funds travel, housing, malpractice, and overhead). You’re not cutting a separate check for housing and flights — that’s baked into the arrangement.

The Assignments Themselves

Engagements are more flexible than most administrators expect. A locum arrangement can be:

• A single weekend shift covering an emergency gap
• One shift per week for ongoing light coverage
• A 7-days-on/7-days-off rotation for sustained need
• A two-weeks-per-month structure
• A full-time 3+ month placement while you recruit permanently

Assignments are extendable. If you need someone through Q1 and they’re a fit, the agency extends the contract. If you find a permanent hire, the engagement ends at the agreed date. The structure bends to your timeline, not the other way around.

Pro Tip:

Use locum coverage as a live audition. Administrators who’ve figured this out intentionally extend assignments for strong performers and then convert to permanent — having already seen how the provider handles your specific patient population, culture, and workflow.

Who This Model Actually Serves Well

Locum tenens started as a rural solution — Dr. Kolff built it in 1979 specifically because small communities couldn’t recruit permanent physicians. That origin still shows up in the data: agencies are especially effective for rural and underserved facilities that struggle to attract permanent candidates.

But the model has long since spread to urban health systems. Teaching hospitals use locums for volume spikes. Specialty clinics use them during maternity leaves. Urgent care chains use them to test new markets before committing to permanent hires.

Nobody tells you this: the facilities that get the most value from agencies are ones with a clear, specific need — not ones trying to fill a vague “we always need more coverage” gap. Agencies are best at solving defined problems with defined timelines.

Practical Bottom Line

If you’ve never worked with a locum tenens agency before, here’s how to approach it:

1. Define the need tightly. Specialty, dates, shift structure, location. Vague asks produce vague matches.
2. Ask about credentialing timelines upfront. A good agency will tell you exactly how long it takes to get a provider privileged at your facility — and flag if your timeline is too tight.
3. Vet the agency’s NALTO membership and credentialing standards. The National Association of Locum Tenens Organizations sets baseline standards; NCQA credentialing is the benchmark for quality.
4. Build the relationship before you’re desperate. The administrators who get the best matches are the ones who’ve briefed their consultant on their facility’s culture before a crisis hits.

The model is straightforward once you understand it. The agencies that execute it well are doing a lot of work you never see. That’s exactly how it’s supposed to work.
