For many small practices, outsourcing billing ends up simpler and less risky than relying on a single in-house biller, because the salary is only part of what that role really costs. But in-house is the right call for some practices, especially ones that already have a strong biller, enough volume to keep that person busy, and a plan for when they're out. The honest answer depends on your volume, your payers, and how much of your own time you can give to managing billing.
I've seen this question from both sides. I have 15+ years in medical practice management: front desk, then practice administration, then billing management, and now my own billing company. So yes, I have a stake in the answer. Here's the version I'd want if I were in your seat.
What an in-house biller really costs
Most owners compare a biller's salary to a billing company's fee. That leaves out most of the picture. Here's what actually goes into an in-house biller:
- Salary and payroll taxes. The obvious part.
- Benefits. Health insurance, retirement contributions, and whatever else you offer to stay competitive.
- Paid time off and sick days. You pay for those days, and claims still need to go out. Someone covers, or the work piles up.
- Training. Code sets are updated every year, and payer policies change constantly. A biller who falls behind costs you in denials.
- Software and clearinghouse fees. Billing software or an EHR billing module, clearinghouse fees, eligibility tools. Some of this may be bundled with your EHR, and some won't be.
- Your management time. Someone has to supervise, review reports, and answer the question “are we actually getting paid?” Usually that's you or your office manager.
- Turnover. Recruiting, onboarding, and the time it takes a new biller to learn your payers and your workflow.
The single-point-of-failure problem
This is the cost that never shows up on a spreadsheet. In a lot of small practices, one person knows the portal logins, which claims are waiting on appeal, and which insurer needs a phone call to move anything along. That works fine until it doesn't.
Say you run a small therapy group with one part-time biller, and that person is suddenly out for several weeks with a family emergency. Claims stop going out. Denials sit. Timely filing deadlines keep running. If they don't come back, you're starting over with very little documentation. If that's where you are right now, I wrote about what to do when your biller quits.
What outsourcing does well
A good billing company takes most of those hidden costs off your plate. You aren't recruiting, training, or buying billing software for an employee.
- Follow-up. In-house billers often get pulled into phones and scheduling. A billing company's whole job is getting claims paid, including the denials and old balances that tend to get pushed to “later.” That's the heart of full-service revenue cycle management.
- Specialty knowledge. A company that works with behavioral health or PT/OT practices every day has seen your payers' quirks before.
- A process that isn't in one person's head. A well-run billing company documents how your account works.
Where outsourcing can go wrong
Outsourcing isn't automatically better. These are the problems worth watching for.
Percentage-of-collections pricing
Many billing companies charge a percentage of what they collect. Plenty of honest companies use this model. But understand the incentive: a large claim and a small claim can take the same work, and only one pays the billing company well. Small balances and stubborn low-dollar denials can quietly slide to the bottom of the pile. Your fee also grows as your practice grows, even when the work doesn't grow at the same pace.
That's why S2S charges a flat monthly retainer plus a per-claim fee, never a percentage of collections. Details are on our pricing page.
Offshore hand-offs
Some companies sell you on a local relationship, then hand the work to a team overseas. That isn't automatically a problem, but you deserve to know who is handling your patients' information and where. Time zone gaps can turn a same-day fix into days of back-and-forth.
Poor visibility and slow communication
If all you see is a deposit hitting your bank account, you can't tell whether your billing is healthy. You need to know what's outstanding, what's been denied and why, and what's being done about it. And when a payer changes a rule or a patient calls about a bill, you want to reach someone who actually knows your account, not submit a ticket and wait.
Questions to ask any billing company before you sign
- How exactly do you charge? Get setup fees, per-claim fees, percentages, minimums, and extras like credentialing or patient statements in writing.
- Who will actually work on my account, where are they, and can I talk to them directly?
- Who covers when my contact is out? Ask every company this, big or small.
- Will you sign a Business Associate Agreement before we share any patient information? The answer should be yes, without hesitation.
- What reports will I get, and how often? Ask for a sample. At minimum you want A/R aging, denials, and payments.
- Do you work in my EHR or your own system? Who owns the data if we part ways?
- What happens to claims from before you start? Old A/R is often a separate project. If yours is a mess, ask about A/R cleanup.
- How long is the contract, and how do I leave? Ask about notice, data handoff, and who finishes claims already in progress.
If you already have a billing company and don't like the answers you're getting, switching billing companies is very doable when it's planned well.
Whatever you choose, keep the keys. Your practice, not just your biller or billing company, should have administrator access to your EHR, clearinghouse, and payer portals. That one habit protects you no matter who does the billing.
When in-house is the right call
I'll say it plainly: in-house billing is the right choice for some practices. It may be right for you if:
- You already have an experienced biller who knows your payers and does the job well.
- You have enough volume to keep a biller focused on billing, not filling in at the front desk.
- You or your office manager know billing well enough to supervise it and spot problems early.
- Someone else on staff is cross-trained to cover when your biller is out.
- You want day-to-day control and are willing to spend the management time it takes.
If that's your practice, keep your biller and invest in them. Pay for training, give them good tools, ask them to write down their process, and look at the reports yourself every month.
Hybrid options worth considering
It doesn't have to be all or nothing.
- In-house front desk, outsourced claims. Your staff handles intake, eligibility checks, and copays while the patient is in front of you. A billing company handles claims, denials, and A/R follow-up.
- Outsourced credentialing only. Credentialing comes in waves: a new clinician joins, you add a payer, re-credentialing comes due. It's paperwork-heavy and easy to lose track of, so some practices keep billing in-house and hand off credentialing and payer enrollment.
- Outsourced prior authorizations. For PT/OT clinics and some behavioral health services, authorizations can eat up hours of staff time. That work can be split off on its own.
- A one-time cleanup. Your biller keeps current claims moving while an outside team works the old balances.
How to decide
Start with a few honest questions. If your biller left tomorrow, could someone else pick up where they left off? Do you know, right now, how much money is outstanding and how old it is? How much of your week, or your office manager's, goes to billing questions?
If those answers make you uneasy, it may be time to look at outsourcing or a hybrid. If not, your in-house setup may be working just fine.
At S2S, we sign a BAA before any patient data changes hands, you get monthly reporting, and you work directly with me, not an account manager or an offshore team. If you'd like a straight answer about your practice, get in touch. If I think in-house makes more sense for you, I'll tell you.
