"What does medical billing cost?" is the first question every practice asks and the one billing companies answer most vaguely. The honest answer: most U.S. practices outsourcing their billing pay 4–9% of monthly collections, with the majority landing between 5% and 7%. But the percentage is only half the story — pricing models, what's included, and the fees hiding in the contract's back pages change the real cost dramatically. This guide breaks down every model with realistic numbers so you can compare quotes like someone who's seen a hundred of them.
The dominant model: the billing company keeps a percentage of what it actually collects for you. Small practices and low-average-claim specialties (mental health, physical therapy) tend to see 6–9%; high-volume or high-dollar specialties (surgery, cardiology, radiology) negotiate 4–6%. The built-in advantage is alignment — the biller earns nothing on claims that don't get paid, so they're motivated to work denials rather than write them off. Verify one thing: the percentage should apply to collections, never to billed charges.
A flat fee for every claim submitted, regardless of whether it pays. It looks cheap for high-volume practices, but the incentive problem is obvious: the biller gets paid for submission, not collection. If you consider per-claim pricing, demand performance metrics in the contract — clean claims rate, denial follow-up turnaround, and AR aging targets.
A fixed retainer scaled to practice size, common for small practices that want budget predictability. It works when volume is stable; it works against you in growth months (you keep the upside) and for the biller in slow months. Most contracts revisit the fee annually against actual volume.
A smaller base fee plus a reduced percentage (for example, $500/month + 3%), or percentage pricing with a monthly minimum. Hybrids exist mostly to protect the billing company on very small accounts — reasonable, but do the math at YOUR volume before comparing to a straight percentage quote.
Specialty: a mental-health practice with $80 average claims takes nearly as much work per claim as a cardiology practice with $400 claims — so lower-dollar specialties pay higher percentages. Claim volume: more volume means better rates. Scope: "billing" quotes may or may not include eligibility verification, prior authorizations, patient statements and support calls, denial appeals, and credentialing — the cheapest quote usually includes the least. Your current mess: practices with months of aged AR to clean up often pay a one-time backlog project fee, or a temporarily higher percentage on old-AR recovery.
Read the agreement for: setup/implementation fees ($0–$1,000 — often negotiable to zero), clearinghouse fees passed through per claim, patient statement fees ($0.75–$1.50 per statement adds up fast), credentialing charged separately ($100–$300 per payer application is typical when it's not bundled), software/EHR access fees, minimum monthly charges that quietly turn your "5%" into 8% in a slow month, and termination clauses — who works the AR from your final 90 days, and what do they keep of it? The percentage on the proposal is the beginning of the price, not the end of it.
An in-house biller costs roughly $45,000–$58,000 in salary, plus 20–30% in benefits and payroll taxes, plus billing software and clearinghouse fees ($400–$800/month), plus training — call it $65,000–$85,000 per year for one person who takes vacations, gets sick, and might quit with your entire AR knowledge. A practice collecting $1M/year would pay $50,000–$70,000 at 5–7% outsourced — comparable money for a team instead of a person, with no turnover risk. Below roughly $800K in collections, outsourcing is usually cheaper outright; above $2–3M, a managed in-house team starts to compete. The full breakdown is in our in-house vs outsourced guide.
Ask every company you evaluate: What is your clean claims rate? What exactly is included — eligibility, prior auth, patient calls, appeals, credentialing? How fast do you work denials, and do you appeal or adjust? What reports do I get monthly? Who owns my data and what happens at termination? Is the percentage on collections only? A company that answers these precisely is worth 1–2 points more than one that doesn't — a 7% biller who collects 96% of what you're owed beats a 4% biller who collects 82% by tens of thousands of dollars a year. Cost matters; net collections after cost is what you actually keep. Our net collection rate calculator shows you where you stand today.
Budget 4–9% of collections for full-service billing, verify what's in scope, hunt the hidden fees, and judge vendors on net collections — not headline rate.
