Dropping a dental insurance plan is reversible in theory and painful in practice, so the decision deserves a spreadsheet before it deserves an opinion. The question is not whether the plan pays badly. It is how much of that plan's patient base would stay with you at your full fee, and whether the extra collected per visit covers the ones who leave.
The honest answer is that nobody can tell you your attrition number in advance. What you can do is model the break even, stage the exit so you are not testing it on your biggest plan first, and control the conversation with patients instead of letting the insurer's letter do it for you.
Run the Break Even Before You Have an Opinion About It
Pull twelve months of production and collections split by plan. For the plan you are considering, you need three things: how many active patients it covers, what it collected, and what the same treatment would have collected at your full fee. The difference between those last two is the write off you are currently absorbing, and it is usually larger than people guess.
Now flip it around. If the plan writes off a quarter of your fee, you can lose roughly a quarter of those patients and stand still on revenue, before you account for the chair time freed up and the claims work you no longer do. Write that percentage on the top of the page. Every conversation that follows is really about whether you believe your actual attrition will land above or below it.
- Active patients on the plan, seen in the last eighteen months
- Collections from the plan over twelve months
- What that same treatment bills at your full fee
- Effective write off percentage, which sets your break even
- Staff hours a month spent on that plan's claims and appeals
Not Every Plan Is Worth the Same Risk
Practices that get burned usually drop the largest plan first, because that is where the biggest write off sits. That is also where the most patients sit. Start with the worst fee schedule you can afford to lose, learn what your real attrition looks like on a few hundred patients, and use that number to decide about the next one.
Look at more than the fee schedule too. A plan whose patients arrive once, take the covered cleaning and decline everything else is worth less than its collections suggest. A plan whose patients accept restorative work and refer their families may be worth staying in even at a poor rate. Sort by revenue per patient per year, not by discount.
Tell Patients Yourself, Before the Insurer Does
The insurer will notify your patients, and their letter will make it sound like you left them. Get in first. Send your own letter six to eight weeks before the termination date, then have the team mention it at every visit in between, so nobody finds out from a claim denial after treatment.
Keep the message short and factual. You are still their dentist, you will still submit the claim on their behalf, their plan will still pay toward the visit, and the difference is that reimbursement now goes to them or comes off differently at checkout. Give the actual dollar difference for a cleaning and exam, because vagueness is what makes people leave. Avoid criticizing the insurer at length: patients read it as a billing dispute they did not sign up for.
What the First Year Usually Looks Like
Attrition does not arrive as a wave. Most practices see almost nothing for the first two months, a cluster of cancellations around the termination date, and then a long slow tail as patients hit their recall date and decide. You will not know your real number until roughly eighteen months in, when everyone on a six month recall has had two chances to not come back.
Collections behave differently. Per visit collections rise immediately, while total collections often dip for a quarter or two before recovering. Plan cash flow for that dip. It is the reason to make this move in a stable year rather than the year you are also buying a scanner or opening operatories.
- Weeks one to eight: quiet, with occasional questions at checkout
- Around the termination date: the visible cancellations
- Months three to eighteen: the slow tail as recalls come due
- Per visit collections up straight away, total collections dip first
Give the Patients Who Would Leave Somewhere to Land
The patients most likely to go are the ones for whom the plan was the only reason they chose you. Some of them will stay if there is an alternative that makes the cost predictable, which is where an in house membership plan earns its keep. Have it built and priced before the termination notice goes out, not three months after.
Everything else is ordinary retention work: filing claims for patients so they do not have to, offering a payment plan for larger cases, and making sure the front desk can quote the out of network cost of a cleaning without checking with anyone. This is also the year your team's phone habits matter most, because every inquiry you drop now is one you cannot afford. A free New Patient Leak Check shows where inquiries are leaking and who outranks you locally, which is worth knowing before you deliberately shrink your covered patient base.
Replace the Volume You Chose to Give Up
Being out of network changes who finds you and why. You are no longer on the insurer's find a dentist list, which quietly sent you patients you never had to earn, so the search and referral side of your practice has to work harder from the day you leave.
Fix the things new patients see first. Your Google Business Profile, your reviews, the pages that answer what a crown costs here, and your directory listings all do the job the insurer's list used to do. Claiming your listing is free, puts your services, hours and fees in your own words, emails patient requests straight to your front desk, and gets the page indexed by Google, which unclaimed registry records are not.
The short version
- Your break even attrition equals the write off percentage the plan currently takes.
- Drop the worst fee schedule you can afford to lose first, not the biggest plan.
- Send your own letter six to eight weeks out, with real dollar figures.
- Expect a collections dip for a quarter and a patient tail lasting eighteen months.
- Have a membership plan and stronger local visibility ready before you send the notice.

Frequently asked
How many patients will I lose if I go out of network?
Nobody can quote you an honest figure, because it depends on your fee gap, how long patients have been with you and what else is nearby. The useful number is your break even: if the plan writes off a quarter of your fee, you can lose about a quarter of its patients and stand still. Model that first, then decide.
How much notice do I have to give the insurer?
Check your participating provider agreement, since notice periods commonly run from thirty to ninety days and some contracts renew automatically if you miss the window. Send termination in writing by a method that gives you proof of delivery, and confirm the effective date in writing before you tell patients anything.
Can I still file claims for patients after leaving the network?
In most cases yes, and you should. Filing on the patient's behalf removes the biggest practical objection to staying with you. The plan pays its out of network benefit, often reimbursing the patient directly, and the patient covers the balance at your full fee. Confirm assignment of benefits rules for your state and each plan.
Should I drop all my PPOs at once?
Very rarely. Staging gives you real attrition data from a smaller group before you risk the rest, and it keeps cash flow steadier while you rebuild new patient flow. Start with the worst reimbursement, wait roughly a year to see how retention actually behaved, then use that evidence to decide about the next plan.
