Medical Billing Cost: What Practices Actually Pay

Medical billing cost falls into three models that show up whether you are comparing an in-house team, an outside billing company, or billing software. The first is a percentage of what the practice actually collects, so the biller only gets paid when the claim pays. The second is a flat fee for each claim submitted, charged whether the claim pays or denies. The third is a flat monthly fee for a set volume of claims, with anything over that volume billed separately. Dental and chiropractic offices that bill on the CMS-1500 or the ADA claim form run into the same three structures, because the work behind each claim, coding review, submission, payment posting, and follow-up, is the same no matter the specialty. The real cost difference between models only shows up when you run your own numbers: multiply your monthly collections by a percentage rate, or multiply your monthly claim count by a per-claim rate, and compare that total to what a flat monthly fee would cost at your volume.

There is no single number, because a cardiology practice with prior authorizations on every imaging order has a different claim mix than a family practice billing mostly office visits. What you can do is run the math yourself. If a billing company charges a percentage of collections, take your average monthly collections and multiply by the quoted rate. If they charge per claim, take your monthly claim count and multiply by the per-claim rate. If they charge a flat monthly fee, divide that fee by your claim count to see your effective per-claim cost, then compare it to the per-claim quote from another company. None of these numbers mean much on their own. They only mean something next to your actual claim volume and your actual collection rate.

The same math applies if you are comparing outside billing to keeping it in house. Add up the hours your front desk and billing staff spend on claim submission, payment posting, and calling payers about denied or aging claims each week, multiply by their hourly pay, and add whatever you spend on clearinghouse and claim scrubbing fees. That total is your real in-house cost, even if no single invoice says
