Understanding Predetermination and Preauthorization in Dentistry

Before starting significant dental treatment, understanding exactly what your insurance will cover prevents disappointment and surprise bills. Predetermination and preauthorization are insurance processes that answer the question: what will I actually owe for this treatment? These tools put your coverage in writing before treatment begins, giving you certainty and protecting both you and your dental provider from billing disputes.

What is Predetermination?

Predetermination is a request to your insurance company asking them to estimate coverage for a specific treatment plan. Your dental provider submits details of the recommended treatment, including tooth numbers, procedure codes, and fees. The insurance company responds with a written estimate showing what they’ll cover, what percentage they’ll pay, what you’ll owe, and any limitations or exclusions.

Think of predetermination as getting a free estimate from your insurance company before you commit to treatment. It’s not a guarantee of payment, but it’s a detailed estimate based on your current plan and coverage status. Predeterminations are valid for a limited time (typically 90 days), so you know your estimate is current.

What is Preauthorization?

Preauthorization, sometimes called prior authorization or pre-approval, is a step beyond predetermination. Your provider submits the same treatment information, but the insurance company evaluates it for medical necessity or appropriateness. If approved, they issue formal authorization confirming they’ll cover the treatment as planned. If denied or questioned, they return with requests for additional information or deny coverage before treatment begins.

Preauthorization is more formal than predetermination. When your insurance issues preauthorization, they’ve confirmed in writing that the treatment is covered. This provides stronger protection than predetermination, which is just an estimate.

Not all insurance plans require or use preauthorization. Some plans only use predetermination. Check your plan documents or ask your insurer what their process is. At Bonin Dental Care, we’re familiar with what your specific plan requires and will handle it correctly.

When You Should Request Predetermination

Request predetermination whenever you’re facing significant treatment or have questions about coverage. Any treatment over a few hundred dollars warrants predetermination. Major restorative work like crowns, implants, or complex cases definitely need it. Treatment where multiple options exist with different coverage levels benefits from predetermination because you can see how coverage differs between options.

Also request predetermination if you have questions about your coverage status. If you’re new to a plan, concerned about waiting periods, or unsure what your deductible status is, predetermination clarifies everything.

Some patients request predetermination for every visit just to understand exactly what they’ll pay. While unnecessary for routine preventive visits, many patients find predetermination valuable for peace of mind, and your provider is usually happy to submit them.

The Predetermination Process

At Bonin Dental Care, when you need significant treatment, we discuss predetermination and ask if you’d like us to submit it. We complete the predetermination request, which typically includes your insurance information, the treatment proposed, specific tooth numbers, procedure codes, and our fees. We submit it to your insurance company electronically or by mail, depending on their process.

Your insurance company then evaluates the request against your current coverage. They consider whether you’ve met your deductible, whether you have annual maximum remaining, whether there are waiting periods that apply, and whether the treatment falls within covered services. They respond within 5-15 business days with an estimate showing their estimated payment and your estimated responsibility.

We then share this predetermination with you. You’ll see exactly what your insurance estimates they’ll pay and what you’ll owe. This lets you make an informed decision about whether to proceed with treatment and when to schedule it.

Common Predetermination Findings

A common finding is that your annual maximum is nearly exhausted, so large treatment will only be partially covered. Predetermination reveals this before you commit. You might then decide to phase treatment across two calendar years to capture two separate annual maximums.

Another common finding is that a waiting period applies, so coverage won’t begin until you’ve been on the plan for the specified time. Again, predetermination reveals this, and you can decide whether to wait or pay out of pocket.

Predetermination sometimes reveals that your plan covers a specific treatment less favorably than expected. A crown might be covered at 40 percent instead of the 50 percent you assumed. Again, you can adjust your planning accordingly.

Predetermination might also identify that alternate coverage exists. Perhaps your plan covers a tooth-colored filling at the same percentage as amalgam, but your provider wants to charge more for tooth-colored. Predetermination clarifies this, and you can choose based on coverage reality.

How Predetermination Protects You

Predetermination prevents surprise bills. Without it, you might receive treatment expecting 50 percent insurance coverage, only to discover later your plan covers it at 20 percent. Predetermination in writing prevents this disappointment.

Predetermination also allows you to negotiate timing. If predetermination reveals that treatment exceeds your annual maximum, you can discuss with Dr. Bonin how to phase work across two years to maximize insurance benefit. Without predetermination, you’d discover this problem after treatment and billing.

Predetermination is also helpful for dispute resolution. If your insurance denies payment later despite predetermination being approved, you have written documentation of what they estimated they’d cover. This documentation strengthens any appeal.

Predetermination Limitations

It’s important to understand that predetermination is an estimate, not a guarantee. Insurance companies can deny claims for medical necessity or other reasons even if predetermination was approved. However, in practice, if a predetermination is issued, the claim is usually approved.

Predetermination is valid only for a limited time, typically 90 days. If you don’t pursue treatment within this window, you need a new predetermination because your coverage status might have changed (deductible situation, annual maximum usage, or even plan changes).

Predeterminations assume your plan status doesn’t change. If you lose coverage or your plan changes, old predeterminations become invalid. Always assume predeterminations are valid only while your plan remains unchanged.
