The Money You Already Earned and Never Collected
A clean claim goes out the door. Roughly 11 times in 100, it comes back denied. That was the initial denial rate across the industry in 2024, up from around 10 percent a few years earlier, and it has kept climbing. For a practice, that number is not an abstraction. It is work you already did, care you already delivered, money sitting on the wrong side of a payer's decision.
Most owners treat the revenue cycle as plumbing. Claims go out, money comes in, and the billing team handles the leaks. That framing is what costs you. The gap between a practice that collects 96 cents of every earned dollar and one that collects 88 does not come from plumbing. It comes from decisions about how the front desk and the billing team actually work, and it is the difference between a good year and a flat one on the exact same schedule of visits.
The denials you never fight
Here is the part that should bother you. When practices do appeal a denial, they win close to half the time. Industry surveys through 2025 put the overturn rate right around 42 percent. Almost half the denied claims that get appealed get paid. So the denials you never appeal are, in large part, money you were owed and simply chose to walk away from.
Most denials never get appealed. Appeals take staff hours, and staff hours are the one thing a busy practice never has enough of, so the denial gets written off, the claim gets closed, and the revenue disappears into an adjustment code nobody reviews. Multiply that by the volume of a $20 million group and the number gets serious fast.
The denials themselves are not random. Payers deny for the same handful of reasons over and over. Prior authorization not on file. Medical necessity not documented to their satisfaction. Eligibility that lapsed between the day the appointment was booked and the day of service. Every one of those is preventable at the front desk or in the first pass of coding, before the claim ever goes out. A denial worked after the fact costs you staff time twice, once to bill it and once to fight it. A denial prevented costs you nothing.
The patient is now your hardest payer
The second leak is newer and it is growing. More than half of people with employer coverage now sit in high-deductible plans, with the average single deductible near $1,900. What that means for you is simple and unpleasant. A larger share of every visit is owed by the patient rather than the insurer, and patients are far harder to collect from than payers.
The numbers are stark. Practices collect somewhere between 95 and 98 cents of what a commercial payer owes. From patients, the collection rate on commercially insured balances runs closer to 34 cents on the dollar. Once a patient balance ages past 90 days, your odds of ever seeing it drop below half. That balance was real revenue when the patient walked in. By spring it is a write-off you are calling bad luck.
The fix is unglamorous and it works. Collect at the time of service. Verify eligibility and estimate the patient's share before the visit, not after. Keep a card on file. Send the statement in days instead of weeks. None of this is clinical. All of it is the business around the medicine, and it is where a surprising amount of your margin is hiding.
What to actually watch
Stop looking only at revenue and start watching three numbers. Your initial denial rate, because it tells you how much rework you are manufacturing for yourself. Your appeal and overturn rate, because a low one usually means you are leaving won claims on the table. And your days in accounts receivable, split between what payers owe and what patients owe, because those two problems have completely different fixes.
A practice that manages those three numbers deliberately does not need more patients to make more money. It needs to keep the money it already earned. That is the cheapest revenue you will ever find, and most of the work is already behind you. You just have to go collect it.
