Contingency Billing Explained: Why "We Don't Get Paid Until You Do" Changes the Incentives

Most billing arrangements come down to one structural question: does the billing company get paid regardless of whether the practice does? For a flat-fee or per-claim arrangement, the answer is usually yes. AMB works differently. It's paid on contingency, a percentage of what it actually collects for the practice, and nothing else.

What contingency billing actually means

No up-front cost. No setup fees. Free patient record setup. No long-term contract locking a practice in regardless of results. AMB's fee is a percentage of collections, sized against the volume and services a specific practice needs, and that fee only exists once money has actually moved from a payer or a patient into the practice's account. If nothing gets collected, AMB doesn't get paid either.

Why that changes behaviour, not just pricing

A flat-fee billing service has already been paid by the time a claim gets denied. There's no financial reason for that company to spend extra time on an appeal, chase a 45-day-old unpaid claim, or catch a coding error before submission, beyond basic professionalism. A contingency arrangement removes that gap entirely. AMB's own framing of it is direct: "We work harder to collect your money since we don't get paid until you do." That's not a marketing line, it's the actual mechanism. Every unpaid claim is unpaid revenue for AMB too, not just for the practice.

It's also why the appeals work and the 45-day claim-chasing aren't optional extras bolted onto a basic package. Under a contingency model, letting a claim sit unresolved costs the billing company money directly. There's no version of this arrangement where AMB is financially indifferent to whether a claim actually gets paid.

What it costs to find out

Nothing, and that's worth stating plainly because it's unusual. No up-front cost to sign up, no setup fee, free patient record setup, and a new client's approvals to submit electronically usually take about a day. A practice can move from a first phone call to a working claims pipeline faster than most other vendor onboarding takes to even schedule a kickoff meeting.

The trade-off worth understanding

Contingency billing isn't free money for the practice. The fee is real, and it's a percentage of collections that would otherwise be entirely the practice's. The trade is between paying that percentage and getting a partner whose financial interest lines up with actually getting the practice paid, versus paying a flat fee to a vendor with no direct stake in whether any individual claim succeeds. For a practice that's been quietly absorbing a high denial rate or a slow reimbursement cycle under a flat-fee arrangement, the math on that trade usually isn't close.

It shows up as service, not just as speed

Andréa Andrikopoulos, an AMB client, described the effect in a testimonial: "American Medical Billing has done an amazing job with our account. Besides billing accurately on a daily basis and doing timely and detailed follow-up on each unpaid bill, they have tailored their system to help our company manage our clients, employees and payors. The personal touch we receive far exceeds any billing service I've used in the past." A vendor with no stake in the outcome doesn't usually get described as tailoring anything. Tailoring costs the vendor time, and time only makes financial sense on a contingency model if it leads somewhere.

AMB is also veteran-owned and locally owned, which isn't a fact about the fee structure, but it's part of the same picture: a business that has chosen to stay small enough, and local enough, that a client relationship is worth protecting for its own sake, not just for a monthly invoice that gets paid either way.

Why thirty years in, this hasn't changed

AMB has run on this model since it incorporated in Illinois in 1994, more than three decades of being paid only when its clients get paid. A structure that only benefits one side doesn't survive three decades of client relationships, some of them running 17 to 20 years by the clients' own account. Practices don't stay somewhere that long on the strength of a sales pitch. They stay because the incentive actually worked the way it was supposed to.

For a practice comparing billing partners, the question worth asking directly is simple: what happens to your fee if a claim gets denied and nobody appeals it? If the answer is nothing, the fee has already been earned and there's no structural reason for anyone on the other side to keep pushing. Under contingency billing, that answer is different by design.
