When a Medical Assistant gives notice, the clinic feels it immediately. Rooming slows down, providers start doing their own vitals and intake, and the schedule you built around a full team stops working by mid-morning. A medical assistant staffing agency exists to cover that gap — supplying screened, credentialed MAs on a per diem, contract, or direct-hire basis while you decide what the permanent fix looks like.
This page is for clinic administrators, practice managers, and site leads at urgent care and outpatient locations across Minnesota who are deciding how to handle an MA vacancy. It covers where agency MAs actually get used, how the three staffing models differ for this role specifically, what a good agency screens for before sending anyone to you, and how the cost works.
Where Minnesota Clinics Use Agency Medical Assistants
Medical Assistants aren't a single job. What the role looks like day to day depends heavily on the setting, and that shapes who you should be asking for.
Primary Care and Family Medicine Clinics
This is one of the most common settings where agency MAs pick up shifts across the Twin Cities and Southern Minnesota. Primary care MAs room patients, take vitals, update medication and allergy lists, administer immunizations, handle injections, run point-of-care testing, and manage a steady stream of refill requests and patient messages between visits.
The pace is predictable but relentless, and the panel size means one open MA seat is felt by every provider on the schedule that day. Per diem coverage tends to fit here because the gaps are often short — a call-out, a vacation week, a leave that starts before your replacement does.
Urgent Care
Urgent care MAs work with less warning and a wider case mix. In a single shift you might see splinting, wound care, EKGs, rapid testing, and a walk-in volume that spikes without notice. Weekend and evening coverage is a common need at urgent care sites, and it's often the coverage that's hardest to fill internally without pushing your existing staff into overtime.
Agencies tend to be useful here because per diem MAs are often specifically looking for the nights, weekends, and holidays your staff would rather not take.
Specialty and Outpatient Surgical Centers
Orthopedics, dermatology, cardiology, ophthalmology, and ASCs each ask for something different — casting, assisting with in-office procedures, pre-op and post-op instruction, specialty-specific documentation. The clinical baseline is the same, but the specific skill set is narrower.
That narrowness matters when you're staffing. An MA with three years in family medicine may be excellent and still need real ramp-up time in a specialty setting. A good agency will ask you which of those skills are non-negotiable for your site before proposing anyone.
Employer and Occupational Health Clinics
Occupational health MAs handle pre-employment physicals, drug screens, DOT exams, injury intake, and workers' comp documentation. The clinical demands are lighter than urgent care; the documentation and compliance demands are heavier, and the volume moves with your employer contracts rather than with patient census.
Sites like these often need coverage in bursts — an onboarding wave for a large employer client, a seasonal hiring cycle — which is a natural fit for short contract placements rather than permanent headcount.
Per Diem, Contract, or Direct-Hire: Which Fits Your Medical Assistant Vacancy
The three models solve different problems, and the difference is more practical than it sounds.
- Per diem covers individual shifts with no ongoing commitment. Use it for call-outs, a provider adding clinic days, or a single uncovered Saturday. You get flexibility; you don't get the same face every time unless the agency can request the same MA back.
- Contract places one MA at your site for a defined stretch — typically weeks to months. Use it for a parental or medical leave, or to bridge coverage while you run a permanent search. Both sides get predictability, and the MA learns your workflow well enough to stop asking where things are.
- Direct-hire is a permanent placement where the agency runs the search and screening and the MA goes on your payroll. Use it when the seat is genuinely permanent and you'd rather not spend your own weeks sourcing and interviewing.
Most clinics end up using more than one. A common pattern: per diem to stop the bleeding this week, contract to stabilize the next few months, direct-hire to close the seat for good. If you want the fuller breakdown of how these models work across roles, see our comparison of per diem vs. contract vs. travel staffing.
One note on scope before you decide: if you're weighing an MA against an LPN or RN for the same seat, the delegation rules and the range of tasks are genuinely different, and that difference should drive the decision more than availability does. Our breakdown of medical assistant vs. nurse covers where the line falls.
What a Medical Assistant Staffing Agency Actually Screens For
"Credentialed" is a word every agency uses. What matters is what specifically gets verified before an MA walks into your clinic.
Certification and Clinical Competency
Minnesota doesn't license Medical Assistants the way it licenses nurses, so certification is a credential, not a state requirement. In practice, most clinics ask for it anyway — CMA through the AAMA, RMA through AMT, or CCMA through the NHA are the common ones — and many employers and payer-driven policies effectively require it.
Beyond the certificate, an agency should be verifying the hands-on pieces: current BLS/CPR, immunization records, a background check, and documented competency in the skills you'll actually need — venipuncture, injections, EKG, vitals, point-of-care testing. Ask how those skills are documented, not just whether they're claimed on an application.
EHR/EMR Familiarity
This is the single most underrated screening question for MA placements, and it's the one that most often determines whether day one is productive or painful.
An MA who has spent four years in Epic will move fast in another Epic shop and slowly in athenahealth or eClinicalWorks. The clinical skills transfer instantly; the charting doesn't. Tell your agency which system you run and ask specifically about experience in that system — including which modules, since inpatient Epic experience isn't the same as ambulatory.
If your candidate pool for a system is thin, that's worth knowing up front rather than discovering it in week one.
Front-Office vs. Back-Office Skill Mix
Some clinics want a clinical MA who rooms patients and nothing else. Others need someone who can also register patients, verify insurance, handle prior authorizations, and cover the front desk when it gets buried. Plenty of MAs do both well. Plenty of strong clinical MAs have never touched a scheduling queue.
Be explicit about the mix when you place the request. A vague request produces a candidate who's excellent at half the job and unprepared for the other half, and neither side finds out until the shift is underway.
What It Costs to Staff a Medical Assistant Through an Agency
Agencies charge an hourly bill rate: the MA's pay plus a markup that covers payroll taxes, workers' compensation and liability insurance, credentialing and compliance costs, and the agency's margin.
For Medical Assistant placements specifically, a few things move that number:
- Skill mix and specialty. A general primary care MA and an MA with casting or in-office procedure experience aren't priced the same, because the available pool isn't the same size.
- Urgency. A shift you need covered tomorrow morning prices differently than one booked three weeks out.
- Shift type. Evenings, weekends, and holidays carry the same kind of premium your own staff differentials reflect.
- Duration. A defined multi-week contract often carries a more favorable hourly rate than scattered one-off shifts, since both the agency and the MA get stability in exchange.
- Location and local supply. The Twin Cities metro and a smaller Southern Minnesota market have different candidate depth, and rates follow.
Any agency that quotes you a flat number before asking about your setting, your EHR, your shift pattern, and your skill requirements is giving you a placeholder, not a price. The more useful comparison isn't bill rate versus your posted MA wage — it's bill rate versus the real cost of the seat staying open: overtime for the MAs you still have, providers absorbing rooming and intake, slower throughput, and the turnover risk that builds when a short-staffed team stays short-staffed. Our fuller breakdown of what agency staffing costs walks through that math.
Getting Started
If you're at the point of making the call, a little prep gets you a better match:
- Define the role precisely. Setting, patient volume, specific clinical skills required, front-office expectations, and your EHR by name.
- Pick a model. Per diem for unpredictable gaps, contract for a known timeline, direct-hire for a permanent seat. Say which one you want, or describe the situation and let the agency recommend.
- Name your shift pattern. Days, evenings, weekends, and how far out you can typically forecast the need.
- Ask the screening questions. How certification is verified, how skills competency is documented, and how deep their MA pool is for your specific EHR.
- Ask about continuity. For per diem in particular, whether you can request the same MA back matters more than most administrators expect. Repeat placements stop needing orientation.

Frequently Asked Questions
What's the difference between hiring a Medical Assistant per diem vs. on contract?
Per diem covers individual shifts with no ongoing commitment — useful for call-outs, vacation coverage, or a single uncovered clinic day. Contract places one MA at your site for a defined stretch, typically weeks to months, which fits a leave of absence or a bridge while you recruit permanently. Contract gives you the same person every day and less repeat orientation; per diem gives you flexibility you don't have to commit to.
Do agency Medical Assistants need to be certified?
Minnesota doesn't license Medical Assistants the way it licenses nurses, so certification isn't a state requirement. In practice, most clinics require it, and the common credentials are CMA through the AAMA, RMA through AMT, and CCMA through the NHA. Tell your agency whether certification is mandatory at your site, and ask how they verify it along with current BLS/CPR, immunizations, and background checks.
How fast can a staffing agency fill a Medical Assistant vacancy?
It depends on the model and the specificity of the role. Per diem shifts move fastest, because the agency is drawing from MAs who are already credentialed and looking for work. Contract and direct-hire placements take longer since they involve matching for fit, not just availability. The biggest variables are how specialized the skill mix is, which EHR you run, and how much notice you can give.
Can a Medical Assistant staffing agency help with EHR/EMR training for a new system?
Agencies generally screen and match for existing EHR experience rather than train MAs on a specific system, since system-specific training is usually tied to your own instance, your templates, and your access provisioning. What a good agency will do is tell you honestly how deep their pool is for your system and flag when a candidate is strong clinically but new to your EHR, so you can plan the ramp-up instead of being surprised by it.
What does it cost to use a Medical Assistant staffing agency in Minnesota?
Agencies charge an hourly bill rate: the MA's pay plus a markup covering payroll taxes, workers' compensation and liability insurance, credentialing costs, and the agency's margin. The rate moves with skill mix, urgency, shift type, placement length, and local candidate supply, so there's no single number that applies to every clinic. The useful comparison is that rate against the full cost of leaving the seat open — overtime, provider time spent on rooming and intake, and slower patient throughput.
