Unethical Dental Billing Practices: What To Watch For

Unethical dental billing practices are claims or patient charges that do not match the care given or the terms of the insurance contract. The most common patterns are billing for a procedure that never happened, upcoding (billing a simple filling as a more complex one), unbundling (splitting one procedure into several codes to raise the total), waiving a copay or deductible without telling the insurer, and balance billing a patient for more than a contracted plan allows. Some of these are done on purpose. Many happen because a biller is rushed, undertrained, or copying a code from the last patient's chart without checking the actual notes.

The difference between a mistake and a pattern is what regulators and insurers look at first. A single wrong code is a correction. The same wrong code on every third claim, or a habit of billing the highest-paying version of a procedure regardless of what the chart says, is a pattern. That pattern is what triggers an insurer audit, a state dental board complaint, or in serious cases a fraud investigation. Front desk staff are often the first people who notice something is off, because they are the ones pulling the chart notes against the claim before it goes out.

These problems show up at every size of practice, from a single dentist with one hygienist to a group with ten locations. The fix is not more paperwork. It is checking the match between the chart, the code, and the patient's plan before the claim leaves the building, every time, not just when someone has time.

Here are the patterns we see most often when we talk to front desk teams and billers:

• Upcoding. Billing D2750 (a crown) when the chart shows a simpler restoration was done. Our D2750 dental code guide walks through what that code actually covers.
• Unbundling. Billing a scaling and root planing procedure as four separate codes instead of the one code that covers the full quadrant.
• Phantom billing. A claim goes out for a cleaning, exam, or X-ray that was never performed, sometimes because a patient no-showed and the appointment was billed anyway.
• Fee forgiveness without disclosure. Writing off a patient's copay or deductible but still billing the insurer the full contracted rate, which misrepresents what the patient actually paid.
• Balance billing beyond the contract. Charging a patient the difference between the dentist's full fee and the insurer's allowed amount when the practice is in-network and the contract does not permit that. Our guide to dental balance billing covers when balance billing is legal and when it is not.
• Misrepresenting a missing tooth. Billing as if a tooth were present when it was already missing, which runs into missing tooth clause rules on many plans.

None of these require a complicated scheme. Most start with a shortcut that someone figured would never get checked.

A few checks catch most of the list above before a claim ever goes out.

• Match the EOB to the chart. When the explanation of benefits comes back, compare the code billed to what the chart notes actually describe. Our guide to reading a dental EOB shows what each line means.
• Check the plan before the visit, not after. A lot of billing disputes start because nobody confirmed what the plan covers before treatment began. Running an insurance verification check before the appointment, with the patient's actual plan pulled up, catches coverage gaps before a code gets picked, not after a claim gets denied.
• Watch for repeat codes. If one code shows up on almost every claim regardless of what was actually done, that is worth a second look, not an assumption that it is fine because it has always been that way.
• Ask who sets the fee the patient sees. A patient should be told the estimated cost before treatment, and that estimate should match what actually gets billed once the insurer responds.

Slow claims are often a symptom of the same root problem, mismatched codes and missing documentation. Our post on what slows dental insurance claims down breaks down the most common holdups we see.

The office, not a vendor, picks the code on every claim. That is true everywhere we work. What a practice can control is making sure the person picking the code has accurate information in front of them before they pick it.

That starts with insurance verification. Running a coverage check before the visit, one click per patient, tells the front desk what the plan actually pays for the procedure being considered, not what it paid last year or what a similar plan paid for a different patient. The ADA Health Policy Institute found that 43.3% of dentists already use AI for at least one task in their practice, and insurance verification is the second most common planned use, at 32.6% planned versus 13.6% currently in use. That gap is mostly offices that still check coverage by phone or not at all, and end up guessing at a code because nobody confirmed what the plan allows.

Claims and collections work, the part that comes after the code is picked, is where a lot of practices lose track of denials, resubmissions, and aging claims. This is an area we are building into Valian now, starting with our first offices. We are not going to tell you it files or collects claims today, because it does not yet. What it does today is give the office clean coverage information up front, so the code that gets picked matches what the plan actually covers. Fewer mismatched claims up front means fewer disputes to untangle later. You can see where this is headed on our dental revenue cycle management page.

For a broader look at what honest, by-the-book dental billing actually requires day to day, our guide on illegal dental billing practices covers the legal line in more detail than the ethics question alone.

If your front desk is spending more time untangling denied claims than checking coverage before the visit, that is usually a sign the verification step is missing, not that the billing team is doing something wrong on purpose. You can book a time to walk through your current process and see where the gaps are.

What are some examples of unethical billing practices?

Common examples include billing for a procedure that was never performed, upcoding to a higher-paying code than the chart supports, unbundling procedures that should be billed under one code, and charging a patient more than their insurance contract allows. Each of these misrepresents either the care given or the amount the patient actually owes.

What are some examples of unethical practices in dentistry?

Beyond billing, unethical practices in dentistry can include recommending treatment that is not clinically necessary, failing to disclose a less expensive treatment option, or misrepresenting a dentist's credentials. On the billing side specifically, the most common issues are upcoding, unbundling, and phantom billing for care that did not happen.

What is the 3-3-3 rule for dental?

The 3-3-3 rule is not a formal billing regulation. It usually refers to informal guidance some practices use around treatment planning timelines or follow-up intervals, and the exact meaning varies by practice and specialty. If a patient or team member hears this term used, it is worth asking the specific office what they mean by it, since it is not a standardized industry term.

What are deceptive billing practices?

Deceptive billing practices are any billing actions designed to make a claim look different from what actually happened, so the practice gets paid more or the patient is charged incorrectly. This includes billing a higher-cost code than the treatment performed, billing for services not rendered, and failing to disclose fee waivers to the insurer while still billing the full contracted amount.
