The short version
- Outsourcing billing doesn’t delete the work — it moves it to a vendor and trades your payroll line for their fee. The AR, the denials, and the patient experience are still yours.
- In-house only wins when you actually build the system: filing, follow-up, month-end, the whole machine. Hire a seat and call it a department, and you’ll underperform any competent vendor.
- Generally speaking, the decision isn’t cost. It’s whether you can sustain follow-up discipline in-house — because that’s where the money is, in either model.
The trade isn’t cost. It’s control.
Practices frame this as a price decision. It is not. Outsourcing billing does not remove the work — it moves it. You trade a payroll line for a percentage, and an employee you manage for a vendor you manage.
The revenue cycle is the same machine either way: charges in, claims out, payments posted, denials worked, month-end reconciled. Someone runs that machine. The only question is whether they sit in your office or in someone else’s.
So decide on the thing that actually changes: control, visibility, and who is accountable when the AR slips. Not the fee. We have walked this same decision for dermatology practices — the shape of the trade is identical. The plastics-specific catches are below.
What outsourcing removes — and what it doesn’t
A good billing company genuinely takes things off your plate. It removes the data entry, the software overhead, the hiring and covering for a biller who quits, and the day-to-day production of claims.
Here is what it does not remove:
- Ownership of your denials and your appeals strategy.
- Your payer relationships and contract terms.
- The patient billing experience — the calls, the statements, the goodwill.
- Accountability to your own P&L when days in AR climb.
You handed over the keystrokes. You kept the risk. That is the part most practices miss when they sign the contract.
Who owns the AR
You can outsource the billing. You cannot outsource owning the AR. A vendor that does not chase your aging is still your revenue bleeding — it just bleeds with a third party’s name on it.
The discipline does not change with the model. Every outstanding claim still has to be touched at least once every 30 days. High-dollar claims still get worked first. Days in AR is still the number that tells you whether anyone is actually doing the work.
So whether the biller is yours or theirs, watch the same metric. If days in AR is climbing, someone is not following up — and it is your money, not theirs.
The real cost comparison
Outsourced billing generally runs 4–9% of collections, with 6–8% common for specialty practices. It scales with volume, carries no management overhead, and turns a fixed cost into a variable one. Bill more, pay more; bill less, pay less.
In-house is a fixed cost stack: salaries, benefits, practice management software, training, and your own time managing the function. MGMA benchmark data is the place to sanity-check your staffing cost against peers. Cheap at high volume, expensive at low volume — the opposite shape of the vendor fee.
Generally speaking, lower-volume practices come out ahead outsourcing. Higher-volume practices that will actually build the system come out ahead in-house. The break-even is not a number you copy from a blog — it is your collections against your fully loaded staffing cost. If you want a second set of eyes on it, that math is exactly what a billing operations review covers. Run it for your own practice before you decide.
Plastics is not generic billing
Plastic surgery billing is not primary care billing. The same patient can generate a cosmetic charge paid up front and an insurance charge that runs the full claim cycle. Reconstructive procedures get scrutinized for medical necessity. Combination cases split across both worlds in a single operative report.
A generic billing company that treats plastics like a family practice will leave money on the table — missed insurance portions, weak medical-necessity appeals, prior auth handled as an afterthought.
In-house, you control that training and keep it. Outsourced, you have to verify it — ask the vendor to walk you through a combination case and a denied reconstructive claim before you sign.
When each one actually wins
There is no universal answer, but there is a clean rule. In-house wins when:
- Your volume is high enough that a percentage fee costs more than a staffed department.
- You will actually build the system — filing, follow-up, month-end — not just hire a seat.
- You want direct control of denials, reporting, and the patient experience.
Outsourcing wins when:
- Your volume does not justify a full in-house team.
- You have no in-house revenue-cycle expertise to lean on.
- You cannot reliably sustain follow-up discipline yourselves — and you would rather pay someone whose whole job is to.
Pick the model you can run well. If you are leaning in-house, we published the full build blueprint — what the in-house billing system actually looks like, including the manual to run it. A disciplined vendor beats a neglected in-house office, and a built-out in-house office beats a vendor you never hold accountable. The model is not the point. The follow-up is.
Frequently asked questions
Is it cheaper to outsource medical billing or keep it in-house?
Generally speaking, lower-volume practices come out ahead outsourcing, because a percentage fee costs less than a fully staffed department. Higher-volume practices that will actually build and run the system come out ahead in-house. The break-even depends on your collections versus your fully loaded staffing cost — salaries, software, training, and management time — not on a fixed industry number.
What percentage do medical billing companies charge?
Most outsourced medical billing companies charge a percentage of collections, generally in the range of 4–9%, with 6–8% common for specialty practices. The fee scales with volume, so it rises as you collect more and falls when you collect less — the opposite cost shape of a fixed in-house team.
Who is responsible for accounts receivable when you outsource billing?
The practice still owns the AR. A billing company produces and follows up on claims, but the revenue, the denials, and the financial outcome remain the practice’s. If the vendor does not work the aging, it is the practice’s revenue that suffers — which is why days in AR should be monitored regardless of who does the billing.
What is a good days in AR for a medical practice?
Days in AR measures how long, on average, money sits unpaid after a claim goes out. Lower is better. Many practices target under 40 days, and a healthy cycle keeps the majority of claims current — under 60 days aged. The number matters more than the billing model: rising days in AR means follow-up is slipping, in-house or outsourced.
Does a billing company need to know your specialty?
Yes. Specialty knowledge directly affects collections. Plastic surgery in particular splits cosmetic and insurance billing, carries heavy medical-necessity scrutiny on reconstructive cases, and generates combination cases that cross both. A generic billing company that does not handle these well will under-collect. Verify specialty expertise before outsourcing.
Should a plastic surgery practice outsource its billing?
Generally speaking, outsourcing makes sense for practices that cannot justify or staff a full revenue-cycle team, and in-house makes sense for higher-volume practices that will build the full system and want direct control. The deciding variables are claim volume, in-house expertise, and follow-up discipline. Either way, the practice owns the AR and should track days in AR and clean claim rate to hold whoever does the billing accountable.
Not sure where your revenue cycle stands?
If your clean claim rate or days in AR aren’t where they should be, that’s a conversation worth having. We’ll look at your numbers and tell you straight.
