PPO Rates Are Frozen. Here's How to Recover the Margin.
January 2025: Your Delta Dental statement shows zero rate increases. Metlife? Same.
A general practice that collected $1.1 million in 2021 and ran a textbook 62% overhead is, five years later, collecting $1.31 million and keeping roughly $348,700 in 2021 purchasing power. That is about $69,000 a year less than it kept before, on more production, with more staff, and no clinical mistake anywhere in the chain. The reason is arithmetic: since January 2021 the dental reimbursement rate index rose 19% while overall inflation rose 27%, and in the first half of 2026 alone reimbursement moved 1.1% against 1.8% inflation, according to the ADA Health Policy Institute.

Here is the part most owners will argue with. The answer to a frozen fee schedule is almost never to drop the plan. For the large majority of PPO-heavy practices, the highest-return move available in the next 90 days is repricing contracts you have never once asked to reprice, and re-sorting which hours those contracts get, not an exit letter. We would renegotiate before we would drop, and we would do it in that order even when the write-off percentage looks indefensible.
A 19% raise against 27% inflation is not a soft market. It is a pay cut you signed, and you renew it by doing nothing.
This Is Erosion, Not Drift
Every adverse trend in a practice is one of two things. Drift is small, steady, recoverable, and you manage it operationally: a supply line creeping up, a lab bill you renegotiate at renewal, a schedule that leaks 20 minutes a day. Erosion is structural and compounding, and it requires renegotiation, repricing, or exit. Our Drift vs. Erosion call on PPO reimbursement is not close. This is erosion, and treating it as drift is the expensive mistake.
Run the numbers on that 2021 practice and you can see the mechanism. Collections grow with the rate index: $1,100,000 times 1.19 gives $1,309,000 today, assuming flat volume. Costs grow with inflation: 62% of $1,100,000 is $682,000 of overhead in 2021, and that same basket at 27% inflation costs $866,140 now. Nominal profit goes from $418,000 to $442,860, which looks like growth on the P&L. Deflate it and the owner is taking $348,709 in 2021 dollars, a real cut of $69,291.
The tell is the overhead ratio. It moved from 62% to 66.2% without a single new hire or a single bad decision. That pushes the practice outside the 58-65% band that Dental Practice Insider puts as normal total overhead, and well outside the 55-60% range high performers hold, with staff and payroll alone consuming 25-28% of collections. You did not lose control of your overhead. Your denominator stopped moving.
And it is structural, not cyclical. Eighteen states passed 37 dental insurance reform laws in 2025, up from 16 laws in nine states the year before, targeting downcoding, bundling, and the other carrier practices that quietly cut the effective rate below the contracted one, per ADA News. Legislatures do not pass 37 laws about a temporary problem. Meanwhile PPO plans account for more than 80% of the dental benefits market, and average reimbursements in many states sit below 50% of provider charges, with plenty of practices paid the same or less than they were a decade ago, as the Georgia Dental Association lays out. Waiting this out is not a strategy. There is nothing to wait for.
What Most Owners Get Wrong: Write-Off Percentage Is a Discount, Not a Margin
The specific mistake is ranking plans by adjustment percentage and making chair-time and exit decisions off that ranking. The owners who make it are usually the ones with the best books: they can tell you to the decimal that Plan A writes off 44% and Plan B writes off 31%, and they have concluded from that alone that Plan A is the one to cut. Consultants reinforce it, because write-off percentage is easy to pull from any practice management system and it produces an outrage number. Average PPO adjustments run 42-45% across general practices, and a $1 million practice with an 80% PPO mix gives up roughly $360,000 a year to write-offs, by Veritas Dental Resources' math. That figure is real and it is worth being angry about. It is also not a decision input.
Our view: write-off percentage is the wrong metric. It measures the size of the discount off a fee you set yourself, which means you can improve it tomorrow by raising your UCR and changing nothing that matters. It says nothing about what the work actually earns. A plan with a 44% adjustment on a restorative-heavy mix that schedules tightly can out-earn a plan with a 31% adjustment on a hygiene-heavy mix with a 22% failed-appointment rate, and most owners have never checked which of theirs is which.
The metric that answers the question is Collections per Provider Hour: net collections divided by the provider chair hours that produced them, computed separately for every payer. Not production. Not per patient. Per hour of the one input you cannot buy more of. Until you have that number for each contract, every plan decision you make is a guess dressed up as analysis.
Plan A Nets $489 an Hour. A 15% Ask Makes It $562.
Take a practice producing $1.4 million, with its largest PPO at 38% of production and a 43% adjustment. Gross production under Plan A is $532,000, and net collections come in at $303,240. That work consumes 620 doctor hours a year, so Collections per Provider Hour under Plan A is $489.
Now price the renegotiation. Contract renegotiation commonly recovers 10-30% increases on major codes, per the Veritas analysis above, so assume a conservative blended 15% lift on the allowed amounts. Net collections go to $348,726. That is $45,486 more. Collections per Provider Hour rises to $562.
Notice what that $45,486 costs you: no marketing spend, no new operatory, no added chair hours, no patient attrition, no staff training, and no change to your clinical day. It drops almost entirely to the bottom line because your overhead is already paid. Against the $69,291 real cut in the earlier scenario, one successful renegotiation on one contract closes roughly two thirds of five years of erosion. There is no other lever in a general practice that pays like that for the hours invested.
The Break-Even Retention Test on Plan A Is 62%
Now run the exit, properly. The Break-Even Retention Test asks what share of a plan's patients you must keep for collections to stay flat: net collections per visit under the plan, divided by net collections per visit out of network.
Plan A averages $328 in full fee per visit and nets $187 after the 43% adjustment. Out of network, on the same procedure mix, assume you actually collect 92% of full fee once you account for courtesy adjustments and the balances that never land, so $302 per visit. Break-even retention is $187 divided by $302, or 62%.
Plan A generates about 1,622 visits a year. Keep 70% of them and you collect $342,770, essentially matching what a 15% renegotiation delivers, but with 487 fewer visits on the books. Keep 55%, which is a perfectly plausible outcome when a carrier steers hard and a competitor two miles away stays in network, and you collect $269,384, a $33,856 loss against simply staying.
The honest version of the exit case is the freed capacity. Losing 30% of Plan A visits frees roughly 186 chair hours, and if you genuinely backfill those at $562 an hour the exit wins outright. If you do not backfill them, you have bought yourself a lighter schedule and flat collections against a rising cost base. We would not take that deal on hope. Backfill demand has to exist before the letter goes out, not after.
Why 35% Plan to Drop and Only 23.5% Actually Do
The ADA's Q2 2026 data shows 35% of dentists planning to drop out of an insurance network while only 23.5% had actually done it. That gap is the most useful number in the whole report. It is not weakness of will. It is what happens when owners run the retention math late, discover their break-even sits north of 60%, and cannot answer where the replacement patients come from.

So do the math first, then decide, and accept that for most practices the answer is: stay, reprice, and re-sort. Drop the plan whose Collections per Provider Hour stays lowest after a serious renegotiation attempt, in a market where you have demonstrated out-of-network demand. Keep the rest, on better paper.
The Renegotiation Ask That Actually Gets Answered
Carriers do not respond to grievance. They respond to specifics and to credible alternatives. Bring the 20 codes that make up the bulk of your plan production, your current allowed amounts, the regional allowables you can document, and your use: chair time, case acceptance, specialty referrals you keep in house. Ask for a defined percentage on named codes with an effective date, not a vague review. If you reach the contract through a third-party network rather than direct, find out which one and whether you can renegotiate that lease separately, because most owners have no idea how many of their fee schedules they are renting rather than holding.
Expect a no on the first pass from the largest carriers. Ask again in 90 days with one more data point: a competing schedule, a new specialty service line, a location. Rate freezes are a negotiating posture, and postures move when the other side keeps showing up with numbers.
Four Moves Before Your Next Renewal Date
This week, pull net collections and doctor chair hours by payer for the last 12 months and compute Collections per Provider Hour for every plan, then rank them. Run the Break-Even Retention Test on your two worst plans so you know your real exit threshold before anyone talks about dropping anything. Identify which contracts are direct and which come through a shared network, and put renegotiation requests in writing on your top two by production with specific codes and specific percentages. Put the renewal and notice dates for every contract on one calendar, because the ask lands differently 90 days out than it does the week after auto-renewal.
What we are watching next: whether that 23.5% exit figure crosses 30% in the Q4 data, and whether the 37 new state reform laws produce measurable movement in effective rates rather than just cleaner denial language. If downcoding enforcement starts returning real dollars to practices, the case for staying and repricing gets stronger still. If the rate index stays frozen through 2027 while inflation runs near 2%, we will revise toward exit faster than we are recommending today, and we will say so.
Before you send a single renegotiation letter, get your own exit threshold on paper. Our free PPO-exit calculator runs the Break-Even Retention Test on your actual per-visit collections and tells you the share of a plan's patients you would have to keep to stay whole: run your own numbers and find out whether your worst contract is a renegotiation or a resignation.
