31.8% of Dentists Are Dropping PPOs. Here's the Playbook.

Here's the playbook up front: rank every PPO you're in by effective write-off, drop the single worst contract first, tell your patients yourself before the insurer does, and keep at least as many of them as your reimbursement rate demands. That last clause is the whole game, and we'll put hard numbers on it below. If your worst plan pays you 65 cents on the dollar, you break even by keeping 65% of that plan's patients. Every patient above that line is a raise.

The trend behind the headline is real and it's accelerating. 31.8% of US dentists said they planned to resign from PPO plans in 2025, per ADA Health Policy Institute data cited by Thriving Dentist. Then the number went up. The ADA's own Q4 2025 economic update found that 35.0% of dentists plan to drop out of some insurance networks in 2026, making network exits the second-most-cited plan for the year, behind only adding staff at 42.3%. This isn't a fringe move anymore. Better than one in three of your peers is doing it or planning to. The question is no longer whether dropping PPOs can work. It's whether you'll execute it in the right order or torch a decade of goodwill by doing it in the wrong one.

Why the Exodus Is Accelerating

The economics stopped penciling. In that same Q4 2025 update, over 55% of dentists named insurance issues, meaning low reimbursement and denials, as a top-3 challenge, and the report states flatly that provider reimbursement rates are not keeping pace with inflation or practice expenses. Your rent went up. Your hygienist's wage went up. Your reimbursement schedule did not. That's not a cycle you wait out. That's a contract you renegotiate or leave.

And this isn't a new complaint that showed up last quarter. In an ADA Health Policy Institute poll conducted in late 2024, more than half of dentists said one of their top concerns heading into 2025 was insurance-related. Two straight years of the majority of the profession flagging the same problem, while write-offs quietly become most practices' single largest expense line, is what turned a grumble into a migration.

There's a structural reason the timing favors owners, too. Dentistry is a supply-constrained profession. The Bureau of Labor Statistics counts 161,400 dentist jobs as of 2025, with employment projected to grow just 6% from 2025 to 2035 and about 4,800 openings per year. Patients in most markets can't simply swap you for an identical in-network dentist down the street, because there aren't enough dentists to make that frictionless. Meanwhile the pool of independent owners is shrinking: 72.5% of U.S. dentists were private practice owners as of 2023, down from 84.7% in 2005. The owners who remain have more pricing power than they think, and the 35% planning exits have figured that out.

Step One: Rank Your Plans Before You Touch a Contract

Do not start by dropping anything. Start with a spreadsheet. For each PPO, pull twelve months of data and compute three numbers: gross production at your full fee for that plan's patients, actual collections after write-offs, and the count of active patients attached to the plan. Divide collections by production and you have your effective reimbursement rate per plan. It will not match the fee schedule the rep showed you, because downgrades, bundling, and denials all live in the gap.

Now rank the plans from worst rate to best. Your exit order is that list, worst first. Two adjustments before you commit. First, check patient overlap: a family with three plan-B members and one plan-A member will behave as a household, not a claim. Second, check referral flow. A plan whose patients feed your highest-margin procedures earns a stay of execution even at a mediocre rate. Everything else gets a date on the calendar.

Operator Math

Let's walk a real scenario, because percentages hide the money. Take a solo GP collecting $1,150,000 a year. The worst plan on the ranking covers 320 active patients who generate $185,000 in gross production at full fee. The contract's effective reimbursement rate, after write-offs and downgrades, is 65%, so those patients actually bring in $120,250 a year. That means the practice hands the insurer $64,750 in write-offs annually for the privilege of staying in network.

Now run the exit. Divide full-fee production by patient count and each of those patients is worth about $578 a year at your posted fees. Your breakeven patient count is the current collections divided by that full-fee value, which comes to 208 patients. And 208 out of 320 is a 65% retention rate. Notice what just happened: your breakeven retention rate equals your reimbursement rate. That's not a coincidence, it's arithmetic, and it's the single most useful rule in this entire decision. A plan paying you 65 cents on the dollar only requires you to keep 65% of its patients to come out even, and practices that communicate well routinely keep more than that.

Say you run a competent transition, which we'll define below, and retain 80% of the plan's patients, which is 256 people. At full fee those 256 patients produce $147,968 a year. That's $27,718 more than you collected in network, from fewer patients and fewer chairs occupied. The 64 patients who left also hand you back their chair time, which your hygiene reactivation list and new-patient flow can refill at full fee. The downside case matters too: keep only 55%, or 176 patients, and you collect $101,728, a $18,522 hole. So the entire bet rides on retention, which is why the next two sections exist.

Retention Is the Whole Game

Patients don't leave because you went out of network. They leave because they found out from a cold letter their insurer sent, framed exactly the way the insurer wanted it framed. Beat the letter. That means:

• Ninety days of runway. Send your resignation letter to the plan, then immediately start telling patients at every visit, by phone for your top 200 by production, and by a plainly written letter to everyone else. Your team should say the same three sentences every time: we're staying your dental office, we'll still file your claims, your out-of-pocket may change modestly and here's the number to call with questions.
• Stay a courtesy biller. Out-of-network doesn't mean cash-only. File claims on the patient's behalf and have benefits assigned where the plan allows it. The patient's experience at the front desk should barely change.
• Build a membership plan before you exit. A flat annual fee covering cleanings, exams, and X-rays with a discount on treatment gives price-sensitive patients a reason to stay and gives your team an answer to "but I need my insurance."
• Script the money conversation. The gap between a patient's old copay and new out-of-pocket is usually smaller than they fear. Show them the actual dollar difference on their actual treatment plan, not a hypothetical.

The Out-of-Network Traps Nobody Warns You About

The ADA News Dear ADA column on out-of-network providers lays out two barriers that catch owners off guard. First, cost estimates get harder. In network, the plan's fee schedule made estimates mechanical. Out of network, you're estimating against a "maximum plan allowance" you can't always see, so your treatment-plan presentations need wider ranges and clearer disclaimers, or you'll spend your mornings on billing disputes. Second, patient steering is real. Insurers actively push members toward in-network providers through their directories, their call centers, and those letters. You will not out-shout an insurer's mail machine. You can only out-relationship it, which is why the ninety-day runway and the personal phone calls aren't optional niceties. They're the countermeasure.

One more operational note: drop one plan at a time and let the dust settle for at least two quarters before the next exit. Sequencing gives you real retention data from your own practice instead of an industry average, and it means a miss on one plan is a bruise instead of a broken leg.

Fund the Transition Before You Need To

Even a well-run exit puts a dip in collections for a quarter or two while the insurer's accounts-receivable cycle changes and a slice of patients wanders. Plan for it like you'd plan for an equipment purchase. Owners can feel this squeeze coming. A working capital cushion of two to three months of overhead, arranged while your numbers are strong, turns the transition dip from a crisis into a line item. Arrange it before you send the resignation letter, not after the first soft month.

Our own numbers back up how live this decision is for operators. It's a small sample and we'll say so plainly, but the pattern in the PPO-exit submissions matches the scenario above: the worst plan in a practice's book is usually far worse than the owner assumed, because nobody had computed the effective rate with denials and downgrades included. Run your real numbers through the exercise before you trust anyone's average, including ours.

The Takeaway

Pull twelve months of data this week and rank your PPOs by effective reimbursement rate, because your breakeven retention rate equals that number and you can't make this decision without it. Drop only the worst plan first, give yourself ninety days of patient communication before the change hits, and keep filing claims so the front-desk experience barely moves. Line up two to three months of working capital before you resign, not after. A third of your peers are already running this play; the ones who win are the ones who sequence it.
