How many staff members does my practice actually need?

Figuring out the right number of staff for your practice is one of the most persistent management challenges in medicine. Too few people and your team burns out, patient wait times balloon, and revenue slips through the cracks. Too many and overhead climbs faster than collections. There is no universal answer, but there are smart ways to find yours.

Q: Is there a standard staffing ratio I can use as a starting point?

Yes, though you should treat it as a benchmark, not a target. The most widely cited starting point comes from the American Academy of Family Physicians, which describes a ratio of support staff per FTE physician: Divide your total full-time equivalent support staff by your total FTE physicians to get your number. Across primary care, that ratio often lands somewhere between 3 and 5 staff members per physician, depending on specialty and practice size.

Research on primary care practices found an average ratio of 4.5 FTE staff per FTE physician, with smaller practices actually running higher ratios (around 5.3) than larger ones (closer to 3.4), likely because larger groups can spread administrative functions more efficiently, according to a study published in the Annals of Family Medicine.

As Physicians Practice has noted, one benchmark study puts the average administrative to physician ratio at about 0.75 administrative staff per physician, though that figure shifts considerably based on your circumstances.

Q: How do I calculate my own staffing ratio?

Start by converting everyone to full-time equivalents. Take each employee’s average weekly hours and divide by the number of hours your practice considers full-time (typically 40). A medical assistant working 20 hours a week is 0.5 FTE. Two front-desk staff working 30 hours each total 1.5 FTE. Add all support staff FTEs together, then divide by your total physician FTEs. The result is your ratio.

To calculate physician FTEs, you can also use a patient encounter approach: Divide total annual patient encounters by the average encounters per full-time physician in your specialty, which typically runs 3,600 to 4,800 annually. This method accounts for part-time physicians more accurately than simply counting heads.

One thing to keep in mind: a 0.5 FTE physician who only works two days a week may still need nearly a full unit of support staff, because patients keep calling for prescription refills and lab results even on days the physician is out. The math does not always scale the way you expect.

Q: Do staffing needs differ by specialty?

Significantly. A high-volume primary care practice running 25 or more patient visits per physician per day has very different staffing demands than a single-specialty surgical practice with fewer but more complex cases.

For orthopedics, for instance, MGMA benchmarks suggest 7.7 FTE staff per physician, though efficient cross-trained teams sometimes operate closer to 5. Ophthalmology and other procedure-heavy specialties typically need more clinical assistants and technicians to prep patients, assist during visits and manage follow-up. Practices with robust in-office ancillary services, such as imaging or lab, need additional staff to run those functions.

Some practices also structure their staffing around encounters rather than physicians. A large ophthalmology group might calculate staff needs based on the number of tests ordered per visit, not just the visit count, since a single patient may generate two or three chargeable encounters during one appointment.

Q: How many billing staff do I need?

A common benchmark, drawn from MGMA’s Benchmarking Success guide, is approximately 2.7 billing staff per physician. That figure is an average across specialties and does not account for practice-specific variables like denial volume, payer mix complexity or how much of your revenue cycle is outsourced.

If you handle billing entirely in-house, a reasonable rule of thumb is one billing person for every two providers. But that assumes your billing staff is experienced, your workflows are tight, and your EHR is doing some of the heavy lifting on claim scrubbing and coding prompts. Practices that outsource portions of their revenue cycle, such as denial management or accounts receivable follow-up, can sometimes run leaner internally, though you still need a point person to manage the vendor relationship.

Q: What factors should I account for beyond headcount?

Several. Here are some of the most important:

Whether billing is in-house or outsourced. In-house billing requires experienced coders, claim submission staff, denial managers and payment posters. Each function may need dedicated coverage once your volume reaches a certain threshold.

Prior authorization volume. Practices that handle a high volume of prior auths internally often need at least one dedicated staff member once the practice reaches three or four providers, because the task is time-consuming and can stall patient care if it falls behind.

Telehealth. Virtual visits require scheduling support, patient onboarding and sometimes technical troubleshooting. If telemedicine is a significant portion of your volume, that creates staffing needs that a purely in-person model would not have.

How well you cross-train. Staff who can rotate between clinical support, front desk and basic billing functions give you flexibility that single-role employees do not. Practices with strong cross-training programs tend to manage short-staffed periods with less disruption and can often operate leaner overall.

Work performed outside the practice. If a hospital system or management services organization handles credentialing, HR, transcription or contract negotiation for you, those functions do not need dedicated in-house staff. Many practices do not fully account for what outside vendors cover when calculating their own staffing needs, which can lead to either overstaffing or confusion about who is responsible for what.

Q: How do I know if I’m understaffed versus overstaffed?

A few warning signs point in each direction. On the understaffing side, watch for consistently long patient wait times, a high rate of billing errors or claim denials, staff members regularly working late and physician time spent on tasks that could be delegated. As Physicians Practice has covered, workload inequity, where one person carries a disproportionate share of the load, is often a sign the practice needs to reassess how it is distributing work before simply adding headcount.

On the overstaffing side, look for idle time, low per-employee productivity and staff unclear on what their role actually is. If tasks are redundant or nobody is sure who owns a given function, that is often a sign that role definitions have not kept pace with how the practice has grown or changed.

One practical method: Have every staff member keep a log over several weeks of every task they perform and estimate the percentage of time spent on each. Then audit those logs together. You will often find tasks no one needs to be doing, functions that could be consolidated and roles that are genuinely understaffed while others have slack.

Q: What role does technology play in staffing decisions?

A significant one, though it cuts both ways. A well-configured EHR can reduce the need for manual data entry, automate appointment reminders, streamline scheduling and simplify claim submission, potentially reducing the headcount required for those functions. Patient check-in kiosks can take registration tasks off your front-desk staff. Integrated practice management systems eliminate duplicate data entry between scheduling and billing.

The flip side: A poorly implemented EHR can actually increase staffing demands, as staff spend more time navigating inefficient workflows or compensating for system limitations. Legacy systems, in particular, can force IT staff and clinical staff alike to work around the technology rather than with it, as Physicians Practice has reported.

Technology investment should be evaluated in terms of what administrative tasks it genuinely eliminates, not just what it promises to. Before hiring to fill a gap, ask whether a technology solution could close it more efficiently.

Q: How does turnover affect my staffing calculations?

Considerably. Physicians Practice has noted that turnover is often a far more costly drain on resources than most managers realize, because you lose accumulated knowledge each time someone leaves, even when they train their replacement. For practices that treat staffing like a simple numbers game, high turnover creates a permanent treadmill of recruiting, onboarding and reduced productivity.

If your staff turnover rate is above 30% annually, it may explain why you seem perpetually understaffed even when your headcount looks adequate on paper. New staff, regardless of experience, are less efficient than veterans, meaning your effective capacity is lower than the raw numbers suggest. Reducing turnover, through competitive pay, flexible scheduling and a reasonable workload, is itself a staffing strategy. Staff burnout affects the entire team, not just physicians, and an overwhelmed front desk or billing department will eventually generate errors that cost the practice more than a new hire would have.

Q: Where should I go for benchmarking data specific to my specialty?

The MGMA publishes the most comprehensive benchmarking data available for physician practices, including staffing ratios by specialty, region and practice size. MGMA’s DataDive tool and its annual Cost and Revenue reports are the go-to sources for practices that want to compare themselves against peers.

The American Academy of Family Physicians and specialty societies for internal medicine, pediatrics and others also publish periodic staffing guidance. For practices that want a more hands-on assessment, a health care management consultant, many of whom work through MGMA's consulting network, can evaluate your specific workflows and recommend adjustments calibrated to your actual operations rather than national averages.

The most important thing is to benchmark against practices of similar size, specialty and ownership structure. A solo primary care physician and a 20-physician multispecialty group are not playing the same game, and treating their benchmarks as interchangeable will lead you in the wrong direction.
