PPO Exit Strategy for California Dental Practices (2026)

Between January 2015 and September 2025, dental reimbursement rose about 30% while general prices rose about 38%, according to the ADA Health Policy Institute's Q4 2025 State of the U.S. Dental Economy, which calls the result a fiscal squeeze on practices (p.15). On $700,000 of PPO collections, those eight index points are roughly $56,000 a year of purchasing power you used to keep and no longer do. Nobody sends you an invoice for it, which is exactly why it keeps happening.

So California owners talk about leaving. In the same ADA report, 40.7% of dentists said they planned to drop out of some insurance networks in 2025, and only 29.3% reported actually having done it a year later: the largest gap between intention and action of any practice decision the HPI tracks (p.16). Here's our thesis, and plenty of consultants will fight us on it: for most California general practices in 2026, going fee-for-service is the wrong move, and dropping your worst-discount plan is the wrong first step. The right first move is to reprice or drop the plan with the lowest Collections per Provider Hour, even when its write-off percentage looks tolerable. The plan you resent is rarely the plan that's costing you the most.

The Gap Between 40.7% and 29.3% Isn't Cowardice

The easy read on that eleven-point gap is that owners lost their nerve. We think a lot of them looked at the real numbers and correctly backed off, then never went looking for the smaller, better trade they could have made instead.

The market backdrop is why. The National Association of Dental Plans reports that 87% of the U.S. population had dental benefits in 2023, split 63% commercial and 37% publicly funded, and that insured patients were twice as likely to visit the dentist every six months than uninsured patients, 60% versus 31%. Dental Economics puts the same shift in historical terms: coverage has gone from 43% of the population in 1994 to roughly 87% today, and the average dentist now appears in more than 26 PPO directories.

Read those two facts together. Coverage is no longer a segment you can opt out of; it's the water. And the hygiene recall behavior that fills your chairs is measurably tied to whether a patient has a plan. A blanket exit in a state where a large share of working patients get dental through an employer isn't a bold repositioning. It's a bet that you can replace six-month recall behavior with nothing.

Twenty-six directories is the other half of the problem. Most owners we talk to cannot name every network they're contracted into, because some of those seats came through umbrella agreements and network access clauses rather than direct contracts. A PPO you can't name is a PPO you can't price.

Plan D Writes Off 24% and Earns $141 an Hour

Here's the specific mistake, and it's made by good operators with real spreadsheets: they rank plans by write-off percentage and cut from the bottom. Write-off percentage measures how big a discount you agreed to. It says nothing about how much money an hour of chair time produces under that plan, which is the only number that competes with the alternative use of that hour.

Take a five-operatory California general practice collecting $1.25 million, with $915,000 of that from four PPO contracts. Ranked by write-off, the plans look like this:

• Plan A: 38% write-off, $360,000 collections, 1,460 provider chair hours
• Plan B: 31% write-off, $268,000 collections, 1,340 hours
• Plan C: 29% write-off, $196,000 collections, 1,120 hours
• Plan D: 24% write-off, $91,000 collections, 645 hours

Now compute Collections per Provider Hour for each. Plan A earns $247 an hour. Plan B earns $200. Plan C earns $175. Plan D, the plan with the shallowest discount and the best-looking contract, earns $141.

The ranking inverts. Plan A discounts hardest and pays best, because the covered mix skews restorative, the schedule fills, and claims go out clean. Plan D discounts least and pays worst, because it's hygiene-heavy, it downgrades, and it generates the preauthorization and resubmission work that eats front-desk time you're already paying for. Our view: write-off percentage is the wrong metric for this decision, and ranking plans by it is how practices drop their most productive contract and wonder why collections fell.

Dropping Plan C: $50,750 Up or $47,950 Down

Once you know which plan is weakest per hour, the question is whether leaving actually pays. That's arithmetic, not nerve. Run the Break-Even Retention Test.

Plan C produced $196,000 from 1,400 patient visits, so net collections per visit under the plan is $140. Out of network, at your full fee schedule and with realistic collection of patient balances, the same visit mix nets $235. Break-even retention is $140 divided by $235, or 59.6%. You need to keep roughly six out of ten of those patients for collections from that cohort to stay flat.

If you keep 75%, you see 1,050 of those visits, which produces $246,750, a gain of $50,750 a year on the same or fewer chair hours. If you keep 45%, you see 630 visits producing $148,050, and you're down $47,950. The swing between those two outcomes is $98,700 on a single contract decision, and the only variable that moves it is retention.

So don't guess at retention. Pull the Plan C roster and split it: patients with five or more years of history, patients mid-treatment, patients whose plan has an out-of-network benefit versus patients whose plan pays nothing out of network. That last split decides the whole thing. If 70% of your Plan C patients sit in plans with no out-of-network coverage, your realistic retention is nearer 45% than 75%, and we'd stay in the plan and fight over the fee schedule instead.

One more trap. Owners assume the freed 1,120 hours refill themselves at better rates. That practice is already collecting $250,000 per operatory. For context, across the 925 practices in the Practice Market Index, our dataset of dental practices listed for sale, median collections per operatory is $200,000 (middle half $146,875 to $268,708, n=643). A practice already running above that band does not have idle chairs waiting to absorb replacement volume. Exit math that depends on refilling is a growth plan wearing a contract plan's clothes.

Half Your Commercial Patients Sit Where Sacramento Can't See

California adds a wrinkle you should price before you sign or cancel anything. The California Dental Association reports that nearly half of Californians with commercial dental coverage are enrolled in ERISA-governed plans, which fall outside the state's current dental network-adequacy assessments. That gap is what CDA-sponsored AB 1629 is meant to close.

Practically, that means for a large share of your PPO patients, the plan design governing their out-of-network benefit, their assignment of benefits, and their balance-billing experience is set by the employer's plan document, not by state network rules. Two patients holding cards with the same carrier logo can behave completely differently the day you go out of network. So the useful question isn't "how many PPO patients do I have," it's "how many of my PPO patients are in self-funded plans with a real out-of-network benefit." That number is your retention forecast. Most practices have never counted it.

Medi-Cal's 49% Shows What California Dentists Actually Do

Nobody should doubt that California dentists will use network exit as a pricing response. In a CDA survey of 1,527 California dentists fielded in late November and early December 2025, 990 of them currently Medi-Cal enrolled, 49% said they would disenroll from Medi-Cal if proposed rate cuts take effect and 30% said they'd see fewer Medi-Cal members. That's Medi-Cal, not commercial PPO, and the economics differ. The behavioral signal transfers anyway.

Look at the 30%, though, because that's the group commercial-PPO commentary ignores. They didn't quit. They chose to throttle volume. On a commercial contract, throttling looks like this: stay in network, cap the number of new Plan D patients you accept per month, stop giving Plan D the prime restorative blocks, and move that chair time to the payers earning $247 an hour. No cancellation letter, no patient attrition event, and the per-hour number moves within a quarter. We'd do that before we'd drop anything, on every contract where break-even retention comes back above 55%.

Repricing Is the Exit Most Owners Skip

The plans renegotiate with practices that can credibly leave. That's the whole game. Walk in with Collections per Provider Hour by plan, your break-even retention for that contract, and a specific number you need, and you're a counterparty. Walk in asking for "better rates," and you're a form letter.

Three things to do before any exit letter goes out. First, get the complete list of every network you're in, including seats acquired through access and leasing clauses, and read what each contract permits a third party to do with your fee schedule. Second, check your termination notice windows, because a 90-day clause missed by a week costs you a full year. Third, decide what you'd do with the freed hours before you free them. If the answer is "market harder," you're not ready.

Do This in the Next Seven Days

Pull last 12 months of collections and provider chair hours by plan and compute Collections per Provider Hour for each contract, then rank them. Take the bottom plan and run the Break-Even Retention Test on it, then flag every patient in that cohort whose plan has no out-of-network benefit. If break-even retention comes back above 55% or the no-out-of-network share is large, book a repricing call instead of drafting a cancellation letter. If it comes back under 50% with a healthy out-of-network share, send the notice and put the date on the calendar.

What would change our mind: if AB 1629 passes and ERISA-plan lives come inside California's network-adequacy assessments, the balance of power in fee negotiations shifts, and selective exit gets cheaper for everyone. We're tracking that, and we're watching whether the 29.3% who actually left in 2025 report higher collections a year out or quietly re-credential. That second number is the one that settles this argument.
