In-House Billing or Outsourced? A Decision Guide for Practices of 1–5 Providers

The thought you had at the end of the month

End of the month. Your billing company's report lands in your inbox — three pages of charts that never answer your one question: why is the money slower than it used to be? The over-90 column, the money owed to you for more than three months, grew again. And the thought arrives, the one every owner has: I should just hire my own person and do this in-house.

Maybe. But “my billing is broken” is not one problem. It is three different problems wearing the same face — and the fix for each one is a different door. There are four doors, not two: fix the relationship with your current vendor, switch vendors, bring billing in-house, or run a hybrid — keep your strong people, buy help only where you are thin. Which door is yours depends on which problem is yours. So diagnose first.

Problem one is your vendor: reports you cannot read, denials nobody can show you working, questions answered in a week or never. That is a company failing — it says nothing about whether outsourcing itself is wrong for you.

Problem two is the model: a percentage fee grows with your collections forever; a salary would have stayed put. Or the opposite: a salary that only looks cheap.

Problem three is your own front end. In Experian Health's State of Claims survey, the top reasons claims get denied are born before the claim exists: missing or wrong information first, authorizations second. The practices that cut denials, in MGMA's polling, fixed the front end and gave denial work a named owner.

What bringing it in-house really costs each month

Picture the first morning of the month. Your new biller's paycheck says about $4,800 — the number you negotiated, and not what she costs you. On top of it leave the payroll taxes, her health insurance, her paid days off: federal employer-cost data put that invisible layer at about 34 cents on top of every wage dollar for employers under 50 workers. So she costs your practice about $6,400 a month, every month, before a single claim is sent — plus roughly $600 more for software, clearinghouse and training.

Then the question that decides everything: how many people does the work take? One person has two hands and one Monday. Practice data work out to roughly one billing person per two providers, at the median; one full-time biller moves 550 to 830 claims a month. Estimates, not promises. And the work she cannot reach does not vanish — it waits in the aging report.

Two short warnings belong here. Billing and coding are related, but they are not the same job. Coding translates the visit into the codes payers pay on, and those code sets change all year (four CMS HCPCS updates in 2026 alone). One economical hire is rarely both jobs, plus the denial specialist, plus her own backup. And taxes do not pick your door: under IRS rules, both models are deductible business expenses, her pay and a company's fee alike.

What the percentage really costs — and what stays yours

A billing company usually charges a percentage of what it collects for you. 2026 pricing guides put the market at roughly 4% to 10% of net collections; small practices are typically quoted 6% to 9%. A reported range, never a quote. Ask what the percentage is calculated on: money collected, not charges billed. Ask what sits outside it: setup fees, monthly minimums, side charges. And ask how it ends before it begins. Many real contracts run one to three years, with 90 to 180 days' notice to leave. The safer structures run six to twelve months, with thirty to sixty days' notice either way. One line is not negotiable: a billing company handles your patients' data, which makes it a business associate under HIPAA, and federal rules require that relationship in a written agreement.

And the part the brochure skips: the day after you outsource everything, a patient still checks in at your front desk. Someone on your payroll registers her, checks her eligibility, captures the charge. That work stays in your building under every model. Outsourcing removes the back office of billing — the front of it, and the oversight, remain yours.

Your two numbers, side by side

Here is the whole comparison, built so each model honestly wins once. Two practices, same collections — $150,000 a month — different amounts of work inside the money. In the first, the money arrives as about 650 claims a month, each one worth a lot — high-value visits, and one strong biller can carry it. In the second, a waiting room that never empties produces about 1,500 much smaller claims: more than double the work for the same dollars, and the work takes two people.

Same dollars, opposite answers: a salary is paid for work, a percentage is paid on money — so the winner depends on the shape of your collections, never just their size. Two honest edges: on salary alone, the two cross somewhere in a wide band — roughly $65,000 to $110,000 of monthly collections. A zone, not a point; an exact break-even is invented. And give the second practice the first one's prices, and its collections — and its fee — would more than double, while its two salaries would not move a dollar. And at lower collections, around $75,000 a month, the fee wins both rows of this table on cost alone — which is exactly why the diagnosis comes first. Now run it with your own month: your collections, your biller's real all-in cost, the fee you were actually quoted. Two numbers. That is the comparison.

The risk that is not on either invoice

Everything above assumed the chairs are filled. In a small practice, billing is usually one person, and she holds what no file does: which payer wants which modifier, which password expired. On vacation, her queue sits untouched — and a claim or appeal that misses its window is typically lost, not delayed. If she resigns, Gallup puts the cost of replacing an employee at half to twice the annual salary. A second chair is not automatically a bench, either: if both people run at full capacity, the day one is out, the hardest accounts slip first. A bench is slack held on purpose, plus real cross-training. Whichever door you choose, build that — and get her knowledge into a file.

What switching companies costs

Door two deserves its price tag. Picture two Mondays. Last Monday under the old company, claims are in flight — submitted, pending, mid-appeal. First Monday under the new one, somebody must own exactly those claims, by name. In-flight work is where switches bleed. Claim connections get re-pointed payer by payer. Your old contract may charge for the exit; the new one charges to set up. Collections usually wobble for a month or two while the new team learns your documentation. So run it with the lights on: the in-flight list as a written deliverable, an overlap of a few weeks if you can, and both ends in the contract.

So which door? Run the rehire test

Start with the diagnosis, because it outranks the math. If your problem is the vendor, fix the relationship or switch companies. If your problem is your front end, no door fixes it — fix it in your building. Only if your problem is the model itself does the cost comparison get the final word.

And when it speaks, it turns on one question — call it the rehire test: is there a biller in the chair today whom you would rehire tomorrow? If yes, the default is the hybrid. Keep her, and buy her the bench she lacks: an independent set of eyes on denials, hands for the backlog, cover for her weeks away — scoped, written, with end dates. If the chair is empty, or the person in it is the problem, full outsourcing earns its percentage. And if your collections are high and stable — roughly $100,000 a month and upward — with a proven biller and a real bench built, pure in-house is the strongest seat at the table. A capped salary beats an uncapped percentage.

One caution about the hybrid: it draws a seam down the middle of your revenue cycle. When a denial traces back to registration, whose is it? If the contract does not answer that first, claims fall through the seam. Our own company sells this — and on our published page, focused projects come “with clearly defined ownership.” Hold any seller to that phrase.

The one page to look at every month

Whichever door you walk through, you need to know — not feel — whether it worked. Once a month, one page, three numbers. First, how fast money comes in: the average days your receivables sit waiting; healthy, in industry summaries, is under roughly 35 days. Second, how much of what you are owed has gone old: the share over 90 days. Healthy is under roughly 15% — and a growing old pile is the earliest symptom of every problem in this guide. Third, how often claims are denied on first submission. Healthy is under roughly 5%. The habit is the point: an owner watching those three numbers sees a problem a full quarter before an owner watching only the bank balance.

Four questions, in order

The first question decides which problem you have. The rest price your door.

1. When a claim is denied, can your company show you — as a list with names and dates — who is working it and since when? If not, your problem has a name, and it is not the model.
2. Of everything insurers and patients owe you, how much has waited more than 90 days — and is that pile smaller or bigger than three months ago?
3. If your biller quit on Friday — or your company lost your account team on Friday — whose job is billing on Monday?
4. How much of your denial problem starts at your own front desk — registration, eligibility, documentation — where no model change reaches?

Our reading

Our answer, in one line: diagnose before you move. If the vendor is the problem, fix the vendor or switch. If your biller passes the rehire test, keep her and buy her a bench. Change the whole model only when the model itself is what is broken.

And here is where we stand, stated plainly, because you should know what each door looks like from where we sit. If you choose full outsourcing, a company like ours runs the whole back office for a percentage — that is the service we lead with, and our fee belongs in your two numbers like anyone else's. If you choose to keep billing in-house, you are not on your own: we also work alongside in-house teams — focused denial reviews, training for your biller, workflow support, hands for a backlog — as defined projects, not a bundle you are pushed into. And the hybrid is simply the two combined, with ownership written down before the first claim. Decide with the pros and cons in front of you; whichever door you pick, pick the version of it that still works your claims during the worst week of the year.
