In-Network vs Out-of-Network Dental Insurance: Should You Drop PPO Plans?
A financial framework for deciding whether to stay in network: how to calculate your true write-off per plan, patient attrition assumptions, the break-even math, and how to drop a plan without losing the practice.
In-Network vs Out-of-Network Dental Insurance: Should You Drop PPO Plans?
TL;DR
- Run the numbers per plan, not in aggregate. Most practices have one or two PPOs doing real damage and several that are fine.
- The number that matters is net collected production per hour of chair time, not the discount percentage.
- Break-even rule of thumb: if a plan writes off 35 percent, you can lose roughly a third of those patients and still be even. Compare that to your realistic attrition estimate.
- Never drop everything at once. Drop the worst plan first, measure for six months, then decide again.
- Going out of network is an operational change as much as a financial one: you need to collect at the time of service and file claims on the patient behalf.
Step 1: Calculate the Real Write-Off Per Plan
Pull a twelve-month report by carrier showing gross production, contractual adjustments, and collections. Then compute the write-off percentage for each plan, which is contractual adjustments divided by gross production.
| Plan | Gross production | Write-off | Write-off % | Net collected |
|---|---|---|---|---|
| Plan A | $420,000 | $71,000 | 17% | $349,000 |
| Plan B | $260,000 | $83,000 | 32% | $177,000 |
| Plan C | $95,000 | $45,000 | 47% | $50,000 |
Plan C in that example is producing less net revenue than its chair time is worth almost anywhere. Plan A is a partner. Treating them as one decision is how practices end up either overpaying for volume they did not need or dropping a plan that was funding the schedule.
Step 2: Convert to Net Production Per Hour
Percentages hide utilization. A plan with a heavy write-off but high-value treatment acceptance can still outperform a lighter plan whose patients only come in for cleanings. Divide net collected production by the clinical hours those patients consumed. That number, compared across plans and against your practice average, is the honest ranking.
Step 3: Estimate Attrition Honestly
The variable everyone guesses wrong is how many patients leave. Attrition is lower when patients have been with you for years, when their out-of-network benefits are strong, when you are in a market with few in-network alternatives, and when the practice offers something clinically distinctive. It is higher when patients came in through the carrier directory, when the plan pays little or nothing out of network, when treatment is largely preventive, and when several in-network practices sit within a few miles.
Segment the patient list for that plan by how they found you and how long they have been active. Patients acquired through the directory are the ones most likely to leave.
Step 4: The Break-Even Calculation
Suppose a plan writes off 35 percent of production. If you go out of network and keep every patient at full fee, your collections from that group rise by roughly 54 percent, because you are now collecting 100 where you collected 65. To end up even, you can afford to lose about 35 percent of that revenue, which is roughly a third of those patients if their value is evenly distributed.
Most practices that plan the transition well report attrition well below that threshold on a single plan. Practices that drop three plans in the same quarter and change nothing else about their patient communication see much worse results.
Step 5: Before You Drop, Try to Renegotiate
Dropping is the last option, not the first. Request a fee schedule review, especially if you have not had one in three or more years. Check whether you are being paid through an unnecessary umbrella or leased network, which is a frequent and quietly expensive problem. Look at whether a different participation tier with the same carrier pays materially better. And consider dropping only the specific plan rather than the entire carrier relationship, since carriers often have multiple networks with very different reimbursement.
Step 6: If You Drop, Run the Transition Properly
Give at least ninety days of notice as required by your contract. Tell patients directly and early, in writing and in person at their appointments, using language about continuing to file claims for them and about what their out-of-network benefit typically covers. Train the team on one consistent explanation, because inconsistent answers at the front desk cause more attrition than the financial change itself.
Operationally you need three things in place: collection of the full fee at the time of service, courtesy claim filing so the patient is reimbursed directly by the carrier, and a pre-treatment estimate process that shows the patient their expected out-of-network benefit before treatment. Membership plans are a common companion move for patients with no dental benefits at all.
Step 7: Measure for Six Months
Track the number of active patients from that plan, net collections from that group, new patient flow, and open chair time. If net collections hold or rise and the schedule stays full, evaluate the next plan. If they fall, you have learned something specific about your market before risking the rest of your patient base.
Frequently Asked Questions
How much do dental practices lose to PPO write-offs?
It varies widely by plan and region. Write-offs commonly run between fifteen and fifty percent of billed production per plan, which is exactly why the decision has to be made plan by plan rather than as a single policy.
How many patients will I lose if I go out of network?
It depends on plan reimbursement, patient tenure, and local competition. Segment by acquisition source: patients who found you through the carrier directory leave at much higher rates than long-standing patients who chose you for other reasons.
Can I stay in network with some plans and not others?
Yes, and that is usually the correct approach. Participation is contract by contract, so you can remain in network with plans that reimburse acceptably and exit the ones that do not.
Do I still file claims for out-of-network patients?
Most practices do, as a courtesy. You collect your fee at the time of service and file the claim so the carrier reimburses the patient directly. It removes most of the friction from the transition.
How much notice do I need to give to leave a network?
Check the termination clause in your participating provider agreement. Ninety days written notice is typical, and some contracts only allow termination at an anniversary date.
Is a membership plan a good replacement for PPO participation?
It helps, particularly for uninsured patients and for patients you expect to lose. It is a retention and access tool rather than a full substitute for the volume a large PPO delivers, so it should be launched before, not after, a network exit.
