The Hidden Minefield in Your Medical Billing Contract 

Percentage-based fees are the industry default. In most of the country, they’re also legally questionable — or outright banned. Here’s what every provider and third-party biller needs to know before signing anything. 

Every medical practice that outsources its revenue cycle to a third-party billing company has signed some version of the same document: a billing services agreement. Most providers skim it. Many sign it the same day they receive it. And nearly all of them have no idea that a single clause buried in the fees section may expose them to regulatory liability, license suspension, or government investigation. 

That clause is the percentage-based billing arrangement — the industry-standard structure where the biller receives a cut, typically 4–10%, of everything collected on the provider’s behalf. It aligns incentives, the argument goes. The biller works harder when the upside is shared. 

The problem is that more than two-thirds of U.S. states have laws that treat this arrangement as fee-splitting — and fee-splitting between a licensed medical professional and a non-physician is, in many jurisdictions, a form of professional misconduct.
