The short version
- In-house billing looks cheaper because the cost is hiding in plain sight: salary, benefits, software, and one person who takes vacation.
- Outsourcing trades that fixed cost for a percentage of what’s collected, plus a team that codes Mohs and path correctly. You manage a vendor instead of an employee.
- Generally speaking, the question isn’t which is cheaper. It’s whether your clean claim rate and days in AR are where they should be. If they’re not, that gap is bigger than the price difference.
The true cost of in-house billing
A biller in the mid-$40,000s, per the BLS, is the sticker price. Then add benefits, payroll tax, clearinghouse fees, software, and the coding education that keeps them current.
The bigger cost never shows up on a pay stub. It’s single-person risk. Your biller takes a week off and the claims don’t. They sit. Days in AR climbs. And aged AR is the most expensive money you own, because the longer a claim sits, the less of it you collect.
Generally speaking, a billing function that runs on one person stops when that person does.
Where dermatology revenue quietly leaks
Roughly 11% of claims get denied on the first pass (Change Healthcare). Flip that around: you code the claim once, then you work it ten times to get paid. MGMA puts the cost of reworking a single denied claim at about $25 in staff time — and that’s before the denials that never get worked at all.
Dermatology makes it worse, not better. Modifier 25 and 59, Mohs staging, path on every specimen. Every one is a place a payer can say no. The leak isn’t dramatic. It’s three percent here, an underpayment nobody appealed there. That’s why it survives: nobody measures clean claim rate against a benchmark, so nobody sees it.
When outsourcing actually wins
Outsourcing wins in three situations. Number one, your denial rate or days in AR sit above benchmark and aren’t moving. Number two, you can’t hire or keep a coder who actually knows derm. Number three, you’re growing, and you don’t want headcount to climb in lockstep with volume.
A real dermatology billing company brings specialty coders, a denial workflow that runs whether the office is slammed or not, and reporting you’d never build for a single practice. It is not automatically better. It’s better when it closes a gap you actually have.
When in-house is the right call
In-house is the right call when you have a tenured biller who knows your providers and your payer grid cold. Your volume is steady. The coordination between front desk, coders, and providers happens because they’re twenty feet apart. That proximity is worth something real.
The point isn’t that one model wins. It’s matching the model to the practice — the same way you’d match a revenue cycle approach to your size and stage.
Five questions before you switch
Five questions. Answer them honestly before you call anyone.
- What’s our clean claim rate and days in AR right now — and how far off benchmark are we?
- If our biller quit tomorrow, how many days until cash flow felt it?
- Are denials getting worked, or getting written off?
- Do we actually have coding depth for Mohs, path, and modifier-heavy visits?
- Are we growing, and can a one-person desk absorb it?
If you can’t put a number on one and three, that’s your answer. You don’t have a build-versus-buy problem yet. You have a visibility problem. Fix that first.
Frequently asked questions
Is outsourced billing more expensive than in-house?
It’s usually a percentage of what gets collected, so it scales with revenue instead of sitting as fixed overhead. Whether it costs more depends on your collections. If it lifts your clean claim rate and works the denials you’re writing off today, it pays for itself. If your in-house desk is already at benchmark, it might not.
Will I lose control of my revenue cycle if I outsource?
You trade oversight down the hall for reporting and scheduled reviews. Generally speaking, a good partner gives you more visibility into your numbers than a one-person desk does, not less. You’re managing a vendor instead of an employee — a different job, not a smaller one.
How long does it take to switch billing companies?
Thirty to ninety days, depending on your PM system, payer enrollments, and how clean your data is. The slow part is credentialing and clearinghouse setup, not the billing itself.
What should a dermatology billing company actually do?
Code Mohs, path, and modifier-heavy visits correctly. Work denials and appeals. Catch payer underpayments. And report clean claim rate, days in AR, and net collections so you can see what’s happening. Submitting claims is the floor, not the job.
Does practice size change the answer?
Usually. A small, stable practice with a strong tenured biller can do fine in-house. A growing or multi-provider practice hits the ceiling of a one-person desk first — that’s typically what forces the decision.
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.
