For a 3 to 5 provider practice, staffing an in house billing function typically costs 110,000 to 146,000 dollars a year in loaded wages, which runs from roughly 4 to 9 percent of collections depending on how much the practice actually bills. Outsourced billing runs 4 to 10 percent of collections industry wide. Neither model wins outright. Which one costs less comes down almost entirely to your collections volume, not your preference.
Every practice owner who has ever gotten a quote from a billing company has run the same mental math: a biller costs maybe 50,000 dollars a year, so why pay a company 7 percent of everything we collect? The math feels obvious right up until someone actually prices out what a biller costs on top of the paycheck, and what happens the day that person quits, takes leave, or simply cannot keep up with a denial from a payer they have never dealt with before.
This is not a pitch dressed up as an analysis. Both models are real businesses run by real practices, and both can be the right call. What follows is the arithmetic, sourced to the Bureau of Labor Statistics, the Society for Human Resource Management, and the Medical Group Management Association, so you can work out which one is cheaper for your practice specifically rather than trusting whichever side is telling you.
What does in house billing actually cost?
Start with headcount. The Medical Group Management Association’s staffing benchmarks put billing staffing at roughly one full time employee for every two to three providers, depending on specialty mix and claim volume. A 3 provider practice needs about 1.5 full time billing staff to keep up. A 5 provider practice needs about 2.
Now price that headcount honestly. The Bureau of Labor Statistics reports a median annual wage of 51,140 dollars for medical records specialists, the occupational category covering medical billers and coders, as of 2025. That is the paycheck. It is not the cost.
The Bureau of Labor Statistics also tracks what employers actually spend per hour of work, wages plus benefits combined. Its most recent Employer Costs for Employee Compensation report found that wages account for 69.9 percent of total compensation in private industry. Benefits, health insurance, retirement contributions, payroll taxes, and paid leave together account for the remaining 30.1 percent. Apply that ratio to the median billing salary and the fully loaded cost per employee comes to roughly 73,160 dollars a year, not 51,140.
| Practice size | Typical billing staff needed | Fully loaded annual staffing cost |
|---|---|---|
| 3 providers | 1.5 FTE | 109,740 dollars |
| 5 providers | 2.0 FTE | 146,320 dollars |
That number still is not the whole cost. It buys claim submission and payment posting. It does not include the practice management software subscription, the clearinghouse fees paid on every claim, a computer and phone line for that employee, or the office manager time spent supervising work nobody else in the building can fully check.
It also does not include what happens when that person leaves. The Society for Human Resource Management puts the cost of replacing an employee at 50 to 200 percent of their annual salary once recruiting, onboarding, lost productivity, and the ramp up time to relearn a practice’s specific payer mix are counted. On a 51,140 dollar salary, that is 25,570 to 102,280 dollars, on top of whatever backlog builds while the seat sits empty. A 1.5 person billing department has no depth. When the one experienced biller leaves, claims do not stop arriving. They stop going out.
What does outsourced billing actually cost, by comparison?
Outsourced medical billing companies typically charge 4 to 10 percent of monthly collections, a range wide enough that the percentage alone tells you little without knowing what is included. WeBill Health charges 6 to 8 percent for full cycle revenue cycle management, prior authorization and advanced eligibility verification included alongside coding, submission, denial defense and accounts receivable follow up, and 8 to 10 percent for accounts receivable recovery work alone. Smaller practices are priced on a flat monthly fee instead, as detailed in our full breakdown of what medical billing companies charge.
Put the two numbers next to each other and the comparison stops being abstract. A 3 provider practice collecting 1.2 million dollars a year, a realistic figure for a primary care or behavioral health group that size, spends roughly 9 percent of collections on loaded in house staffing alone, before software, before turnover risk, before a single denial gets appealed. That already sits above the top of WeBill Health’s full cycle percentage range. A 5 provider practice collecting 4 million dollars a year, more typical of a procedural or higher volume specialty, spends under 4 percent of collections on the same 2 FTE staffing model. That sits comfortably below the outsourced range.
| 3 provider practice, 1.2 million dollars a year | 5 provider practice, 4 million dollars a year | |
|---|---|---|
| Fully loaded in house staffing cost | 109,740 dollars | 146,320 dollars |
| Staffing cost as percent of collections | Roughly 9 percent | Under 4 percent |
| WeBill Health full cycle RCM | 6 to 8 percent | 6 to 8 percent |
Collections volume decides this comparison more than anything else. A smaller practice pays a fixed staffing cost against a smaller revenue base, and the percentage climbs. A larger practice spreads the same headcount over more collections, and the percentage falls. This is arithmetic, not opinion, and it is why the honest answer to which is cheaper is always the same: it depends on your number, not the industry average.
The part the arithmetic still leaves out
None of the figures above account for what actually gets collected, only for what it costs to try. A biller working alone, without a specialty specific payer rule library behind them, is doing every job at once: coding, submission, eligibility, prior authorization, denial follow up, credentialing renewals, all on top of whatever the front desk hands them at 4 in the afternoon. Something on that list gets deprioritized every week, and it is usually the appeal on a denied claim, because appeals are slow and the phones are ringing.
Get your Revenue Defense Score. Six questions, sixty seconds, and a benchmarked view of how much revenue your current billing setup, in house or outsourced, is actually leaving on the table. It will not tell you which staffing model to choose. It will tell you whether the model you have now is working.
When does in house billing actually win?
It wins more often than outsourced billing companies like to admit. A practice collecting well above 3 million dollars a year, with a stable payer mix, low staff turnover, and a biller who already knows that practice’s specialty cold, can run in house billing at a lower percentage of collections than almost any outsourced quote, the table above shows exactly why. Scale is the entire argument for keeping billing in house. A fixed staffing cost divided by a larger revenue base gets cheaper every time collections grow, and an experienced in house biller who has worked the same payer relationships for years carries institutional knowledge that takes an outside partner months of the same relationships to build.
In house also wins on data control for practices that need it, and it avoids the handoff period every outsourcing switch requires, the weeks where an outside partner is still learning a practice’s payer mix and claim history. A practice that already runs a low denial rate, has depth on its billing team so one departure does not stall claims, and collects enough to keep 1.5 or 2 people fully utilized is not a practice that needs to switch.
The practices that lose money on this decision are the ones running in house on the smallest end of the range, at or below the 1.2 million dollar collections figure above, with one biller carrying the whole function, no backup if that person leaves, and a denial rate nobody has actually measured.
What this means for a 3 to 5 provider practice deciding right now
Run your own version of the table above before deciding anything. Pull your trailing 12 months of collections. Price your actual billing staff, fully loaded, not just the paycheck, using the 43 percent benefits load figure above as a floor. Divide one by the other. If the result sits above 8 percent, an outsourced quote is very likely cheaper before you even account for denial recovery, and the in house model is running on borrowed time the day your one experienced biller gives notice. If it sits well under 6 percent and your denial rate is already low, in house is very likely the more economical choice, and no billing company’s percentage will beat what you are already doing.
The one number this arithmetic cannot give you is your actual denial rate, and that number usually matters more than either staffing model. WeBill Health maintains internal payer rule libraries organized by specialty and by carrier, spanning more than 500 payer rulesets, built and updated by people who work claims in your specialty every day. Every claim receives human pre submission review against those libraries before it goes out. There is no black box and no algorithm we ask you to take on faith. When a payer changes a policy, a person updates the library and a person applies it to your claims. That is the piece of the comparison a spreadsheet cannot show you, and it is usually worth more than the percentage itself.
Find out what your billing setup is actually costing you
A Revenue Defense Audit is a forensic review of your existing accounts receivable, whether you bill in house or through an outside partner today. We show you the real denial rate, the real days in accounts receivable, and the real revenue leaking out of your current setup, then quote a specific percentage if outsourcing turns out to be the better number for your practice. Root cause denial work, not resubmission on repeat, is what Denial Defense 2.0 is built for, whichever staffing model you run.
Frequently asked questions
How many billing staff does a 3 to 5 provider practice actually need?
Industry staffing benchmarks put it at roughly one full time billing employee for every two to three providers, so 1.5 full time staff for a 3 provider practice and about 2 for a 5 provider practice, depending on specialty and claim volume.
Is outsourced billing more expensive than in house billing?
Not necessarily. It depends on your collections volume. Below roughly 1.5 million dollars a year in collections, fully loaded in house staffing often costs more than an outsourced percentage quote. Above roughly 3 million dollars, in house staffing usually costs less on a pure percentage basis.
What does in house billing cost besides salary?
Employer benefits, typically adding about 43 percent on top of wages per Bureau of Labor Statistics data, practice management software, clearinghouse fees on every claim, and the cost of replacing a departing employee, which the Society for Human Resource Management puts at 50 to 200 percent of that employee’s annual salary.
Does outsourcing mean losing control of billing?
You lose day to day claim entry, not visibility. A properly run outsourced partner should give you the same accounts receivable data an in house team would, plus a named contact who works your specialty, not a ticket queue.
When does in house billing actually cost less?
At higher collections volumes, with a stable payer mix, low staff turnover, and a billing team already running a low denial rate. Scale is what makes in house billing cheaper, not preference.
What is the fastest way to know which option is cheaper for my practice?
Divide your fully loaded annual billing staff cost by your trailing 12 month collections. Compare that percentage against a 6 to 8 percent outsourced quote, then get a Revenue Defense Score to see whether your current denial rate is quietly erasing whichever number wins.
