Dental Insurance Predeterminations and Preauthorizations: Do Delays Hurt Case Acceptance?
A patient agrees that a crown, bridge, implant, denture, or periodontal procedure makes sense. Then someone says, “Let’s send it to insurance and see what they say.” The clinical decision has been made, but the financial decision is now waiting on a third party. Days become weeks. The tooth stops hurting. The patient gets busy. By the time the estimate arrives, the urgency that existed in the operatory may be gone.
That delay is real. The American Dental Association says slow turnaround on preauthorization often frustrates patients and dentists. Delta Dental of North Carolina tells patients to allow 10 to 14 business days for a pre treatment estimate when all necessary information is submitted. Delta Dental of South Dakota explains that the review may involve the proposed treatment, radiographs, clinical notes, diagnosis, eligibility, deductibles, remaining benefits, and plan limitations.
The terminology also matters. Preauthorization and predetermination are not the same thing. Some plans may require authorization before certain treatment, while many PPO predeterminations are voluntary estimates. They are not guarantees of payment. Eligibility can change, annual maximums can be consumed, and other claims can alter the final benefit before treatment is completed.
This becomes especially important in patient communication. “Your insurance company approved your crown” can sound like a clinical judgment when it is really a financial estimate. Insurance determines benefits. The dentist determines diagnosis and treatment.
Dr. Travis Campbell, a longtime Dentaltown contributor widely known as the Dental Insurance Guy, has done valuable work helping dentists understand the operational side of insurance. His phrase “delay kills urgency” captures something many dentists have seen firsthand. When patients leave the office and wait several weeks for an estimate, treatment can lose priority. Work, family expenses, vacations, car repairs, and everyday life move to the front of the line.
That observation is plausible and useful, but it is important not to claim more than the evidence supports. Predetermination has historically been studied as a cost containment mechanism. A 1995 study of a publicly funded dental program in Manitoba found that about one third of monthly dental expenditures were subjected to predetermination. Of the treatment dollars reviewed, 26 percent were denied or removed, producing estimated savings equal to 8.5 percent of total monthly expenditures.
That study shows that predetermination can reduce payer spending. It does not show that modern U.S. insurers intentionally delay decisions so patients abandon treatment.
That distinction matters. Dental insurers clearly have incentives to control costs. Plans openly use exclusions, annual maximums, frequency limits, alternate benefits, utilization review, and least expensive alternative treatment provisions. The ADA itself describes least expensive alternative treatment clauses as a cost containment mechanism. But an economic incentive is not proof of intent.
There are many other reasons a predetermination may take time. The request may be incomplete. Radiographs or narratives may require review. Coordination of benefits may be involved. Some procedures may need manual clinical review. Administrative queues and legacy systems can also turn a task that requires minutes of actual review into days of waiting.
From the dental office’s perspective, however, the practical consequence may be the same. The patient is waiting, the schedule is open, and treatment momentum may be fading.
Another statistic often repeated in dentistry says that 70 percent of predeterminations nationwide never become completed treatment. I have not found a publicly available ADA study, National Association of Dental Plans report, peer reviewed paper, government dataset, or national claims analysis establishing that figure. Until the original dataset and denominator are identified, that number should be treated as an interesting hypothesis rather than an established national benchmark.
The better approach may be for dental practices to measure the problem themselves. Track how many predeterminations are submitted, how long each payer takes to respond, how many proposed cases are eventually scheduled, how many disappear, and how much treatment value is lost. Break the numbers down by carrier and procedure. Within a few months, a practice may have more useful information about the true effect of predeterminations on its own patients than any national statistic could provide.
Predeterminations can be useful. For expensive or complex care, an advance estimate may reduce financial uncertainty and help patients make better decisions. But they should be used strategically, not automatically. When a predetermination is voluntary, the question should be whether waiting is helping the patient or simply inserting another delay between diagnosis and treatment.
How much treatment is your practice losing while everyone waits for an estimate?
