The Revenue Mix That Decides What You Are Worth
2 practices in the same specialty, in the same city, book the same revenue. One is worth close to twice the other. The difference has nothing to do with the medicine and everything to do with who pays the bills.
A dollar of revenue is not a dollar of revenue in healthcare. Commercial insurers pay a large premium over government programs for the identical service. National benchmarking in 2025 put commercial rates somewhere between roughly 196 and 230 percent of Medicare, depending on the service and how you count. Call it around double. The same procedure, the same room, the same fifteen minutes of a physician's time pays twice as much when a commercial plan is on the other end instead of Medicare.
That gap is the most important economic fact about your practice, and most owners track it loosely if at all.
Payer mix is a lever, not weather
Owners tend to treat their payer mix as whatever walks through the door. But the share of revenue that comes from commercial plans, versus Medicare, Medicare Advantage, and Medicaid, is the single biggest driver of your margin, and you have more control over it than you think.
The commercial line is what funds everything past your fixed costs. Physician compensation, new hires, the equipment you keep postponing, the cushion that lets you sleep. Government programs, by design, pay near or below the cost of delivering the care. A practice heavy on Medicare and Medicaid can be busy, well run, full of good clinicians, and still have almost no margin to reinvest, because the mix is doing the deciding.
You can move it. Which plans you contract with and renegotiate. Which referral sources you cultivate. Which service lines you expand and which you let shrink. Where you open the next location and what its neighborhood's coverage looks like. None of these is a fast lever. Each of them is a lever, and a practice that pulls them deliberately over a few years looks financially different from one that let the door decide.
The ground is moving under the government line
The pressure is not holding still, and it runs the wrong way. Medicare's conversion factor, the number that sets what the program pays, has been flat to falling in real terms for years while your costs have not. A useful rule of thumb from the people who model this: 2 percent change in the conversion factor moves total practice revenue by roughly 0.4 to 0.7 percent, depending on how much of your book is government. If a third or more of your revenue is Medicare, every cut lands straight on your margin, and the cuts keep coming.
Medicare Advantage deserves its own warning. It looks like Medicare with a private administrator, and it does not behave like one. Advantage plans deny initial and final claims at more than double the rate of traditional Medicare, which means more prior authorizations, more appeals, more staff time, and slower cash, all on top of the lower reimbursement. Growth in your Advantage panel is not the same kind of growth as commercial. Know which one you are adding before you celebrate the new patients.
What this means the day you sell
If a transaction is ever in your future, this is where value gets made or lost. Buyers pay up for commercial revenue because it is higher and steadier, and they discount government revenue because it is thinner and exposed to political decisions no owner controls. A shift in mix can move enterprise value by millions on the same top line. The practice that has managed its payer mix for years before any conversation is the one that gets the number it wants when the conversation finally comes.
You do not need a sale on the horizon to care about this. The mix that makes you attractive to a buyer is the same mix that pays for the hires and the equipment while you still own the place. Look at your revenue by payer this quarter. If you have never seen it laid out that way, that first look tends to explain a lot.
