PPO dependency is one of the most common, and most invisible, problems I see in dental practices. After 42 years of coaching, I can tell you that most practice owners who have it do not think of themselves as PPO-dependent. They think of themselves as busy.
The schedule is full. Patients are coming in. Production looks healthy on paper. But when we sit down and look at what they actually keep, the picture changes.
PPO dependency is not about whether you accept insurance. Nearly every practice does. It is about whether the structure of your revenue has quietly shifted to a point where insurance contracts are dictating your income, your schedule, and your growth ceiling without you realising it.
Here are the signs I look for.
What is PPO dependency in dentistry?
PPO dependency means your practice has reached a point where the majority of your revenue, typically 75% or more, comes from patients on PPO insurance plans. That means the fees you collect are not set by you or by the market. They are set by contracts you may have signed years ago.
The problem is not the insurance itself. The problem is that your costs rise every year (team compensation, lab fees, supplies, rent) while your PPO reimbursement rates stay flat or decrease. The gap between what you produce and what you keep widens silently, year after year.
Your PPO write-offs are climbing but reimbursements have not
Pull your write-off total from the last 12 months. Not the line item on your P&L, but the actual dollar amount you produced in clinical work and then contractually returned to insurance companies.
For practices that are more than 75% PPO-dependent, that number typically lands between $200,000 and $400,000 per year.
Here is the part that makes it worse. Your PPO reimbursement rates have likely stayed flat or decreased over the last five years. But your overhead has gone up every single year. That means the gap between what you earn and what you keep is widening, and it will continue to widen for as long as those contracts are in place.
Your dental practice schedule is full but your profit margins are thin
This is the most common version of PPO dependency I see. The practice looks busy. The schedule is packed. But the doctor is working harder every year and taking home roughly the same amount, or less.
The reason is that PPO plans cap what you can charge per procedure. That cap does not move with inflation. So your production per hour of chair time is fixed by a contract you may have signed a decade ago, while every cost around you has increased.
A practice producing $5,000 per day on a full PPO schedule could be producing $7,000 to $8,000 per day on a fee-for-service schedule. Same hours, same chair, same team. Over a year, that difference is $400,000 to $600,000 in revenue that was never collected. Not because the work was not done, but because the contract said so.
You have not run a PPO write-off report by plan
Most practice owners can tell you their total write-off number. Very few can tell you which specific insurance plan is responsible for the largest share of those write-offs relative to the number of patients it brings in.
This distinction matters. A plan that accounts for $80,000 in annual write-offs sounds expensive. But if it also represents 400 active patients, the per-patient cost is $200. Another plan might only account for $30,000 in write-offs but only bring in 60 patients, making the per-patient cost $500. That second plan is far more expensive on a per-patient basis, even though the raw number is lower.
Until you run a write-off report sorted by plan and cross-referenced against patient volume, you are making decisions about PPO participation based on incomplete information.
Your patient mix has shifted toward insurance-driven patients
This is the fear that keeps most PPO-dependent practices locked in. The concern is that if you resign from a plan, the patients on that plan will leave.
Some will. But the question is how many, and which ones.
Patients who chose your practice because of the insurance benefit, not because of your clinical reputation, your location, or their relationship with you, are the ones most likely to leave. Over time, a heavily PPO-dependent practice accumulates more and more of these insurance-driven patients. The patient mix shifts without you noticing.
The result is a schedule filled with patients whose loyalty is to their insurance card, not to you. And that creates fragility. If a plan changes its terms, drops your reimbursements further, or removes you from the network, you lose patients you never truly had.
Your team is not trained for a fee-for-service conversation
Here is a test I recommend to every practice owner I coach. Ask your front desk this question: if a patient calls and says “Do you still take my insurance?”, what does your team say?
If the answer is a stammer, a redirect, or an apology, you have a verbal skills gap that will cost you patients the moment you make any changes to your PPO participation.
The practices that successfully transition away from PPO dependency train their teams before sending a single resignation letter. The front desk needs to be able to articulate the value of staying with the practice in terms the patient understands, not in terms of insurance networks.
This is not a clinical issue. It is a communication infrastructure issue. And it is one of the five mistakes I see most often when practices try to reduce PPO dependency without preparation.
Your dental fee schedule is below the 80th percentile
Fee-for-service practices update their fees annually using regional data. PPO-contracted practices often do not, because the reimbursement is fixed regardless of what you charge.
The result is that many PPO-dependent practices have fee schedules sitting at the 40th or 50th percentile for their zip code. Not because they chose to price low, but because they stopped paying attention to fees that the insurance company was going to override anyway.
This creates a compounding problem. If you ever do resign from a PPO, your fee schedule is now too low to capture the full value of fee-for-service patients. You traded insurance discounts for self-imposed discounts.
Before making any moves on PPO participation, your fees need to be recalibrated to at least the 80th percentile using current NDAS data. That is not about charging more for the sake of it. It is about aligning your fees with the actual market value of the work you do.
How to assess your PPO dependency and what to do next
If three or more of these signs apply to your practice, PPO dependency is likely the primary structural issue holding back your profitability. Not your clinical skills, not your patient volume, not your team. Your revenue structure.
The good news is that this is fixable, and the first moves cost you nothing but attention.
Start with the numbers you already have. Pull your write-off total for the last twelve months and sort it by plan, then divide each plan’s write-offs by the number of active patients it brings you. You will almost certainly find that one or two plans are quietly costing you far more per patient than the rest. Then pull your fee schedule and compare it against current regional data. If you are sitting below the 80th percentile, you are discounting yourself before the insurance company even gets involved.
Neither of those exercises requires you to resign from anything. They simply replace assumption with fact.
Because that is what PPO dependency really is: a problem that persists because it is invisible. It does not announce itself with an empty schedule or an angry patient. It shows up as a busy practice, a tired owner, and a bank balance that never quite reflects the work being done. The contracts keep their terms. Your costs keep climbing. And the gap between what you produce and what you keep widens quietly, year after year, until someone finally looks.
I resigned from 34 PPO plans at my own practice. It was not a leap of faith. It was a decision made with the numbers in front of me, after preparation, one plan at a time.
You do not have to make that decision today. But you should know what it would cost you not to.
