Top 10 Illegal Dental Billing Practices and How We can Avoid Them

Top 10 Illegal Dental Billing Practices Every Dentist and Patient Must Know

Illegal dental billing practices are a serious and growing issue in the USA’s dental industry, costing insurers, patients, and providers millions of dollars every year. According to Medicaid, some outlier dentists have billed more than $1,000 per child in states where the average was around $250, raising red flags for potential fraud.

At I-Med Dental Solutions, we believe in setting high standards of transparency and compliance. Our dental billing experts ensure adherence to HIPAA and other regulations to support billing and sustainability for your dental practice.

In this blog, we’ll take you through some of the most common illegal dental billing practices, their consequences, how to spot them, and best practices to avoid them.

The Consequences of Illegal Dental Billing

Illegal dental billing practices are more than just coding errors or data entry mistakes. They have a negative impact on the financial health of dental practices, increase costs for patients, and affect the overall integrity of the dental industry.

Understanding why these practices matter is the foundation of building a compliant and ethically strong dental industry.

The Financial Impact on Stakeholders

Illegal billing has a negative impact on the entire healthcare system, costing billions of dollars every year. When insurance companies find out about fraudulent activities such as upcoding, unbundling, or billing for services not performed, they respond by raising premiums, tightening authorization rules, and enforcing aggressive claim inspections.

Although such steps are taken to curb malpractices, they also create hurdles for genuine dental practitioners, dental surgeons, solo dentists, etc, who follow ethical billing measures. They are also going to face:

  • tighter documentation requirements
  • delayed reimbursements
  • increased administrative workloads

It is important to note that negligible instances of improper billing or illegal activity can  make it harder for compliant practices to operate efficiently.

How Patients Are Affected, Financially and Clinically

Patients often experience the hidden consequences of fraudulent billing long before they realize it. When billing is inaccurate:

  • They may have to pay more out of their pocket for treatments
  • Annual insurance benefits can exhaust prematurely
  • Unnecessary treatments may be recommended to justify higher billing codes

This isn’t just a financial problem; it becomes a clinical issue. In many cases, unethical billing correlates with overtreatment, meaning decisions may be influenced more by reimbursement potential than by true patient needs. Over time, this leads to a loss of trust that’s extremely difficult for any provider to regain.

Serious Risks for Dental Practices

For dental practices, illegal billing is more than just a financial issue. Insurance companies, whether Medicare, Medicaid, or commercial payors like Aetna, Cigna, Delta, BCBS, or United Healthcare, start their inspection activities.

They do it to analyze patterns in submitted claims, ranging from incorrect dates, documentation inconsistencies, and unusual procedure frequency. Many payors that detect discrepancies invest in comprehensive dental billing audits. It helps them identify outcomes like:

  • Repayment demands
  • Exclusion from insurance networks
  • State board investigations
  • Civil liability
  • In severe cases, criminal charges

It is important to remember that unintentional mistakes in claim creation or appending wrong CDT codes or HCPCS modifiers may also lead to penalties. The law generally focuses on the outcome of the claim and not the provider’s intent.

The Ethical and Reputational Damage

Any dental practice thrives on trust between the patient and the provider. Patients think that treatments recommended by dentists are necessary, accurate, and billed transparently. When fraudulent billing practices occur, the dental practices doesn’t only have to deal with payment problems.

It affects:

  • The practice’s and the dentist’s credibility
  • Staff’s morale
  • Dental Practice’s reputation

Once trust is broken, rebuilding it is incredibly challenging. Ethical billing is therefore not just about compliance; it is a pillar of patient-centered care.

Why Prevention Matters More Than Correction

Illegal billing can stem from simple oversights, rushed charting, lack of staff training, and confusing coding requirements. Leading dental billing experts advise preventing such wrongful practices.

Correcting problems after the fact is resource-intensive, expensive, and disruptive than building a compliance-focused workflow from the beginning. By committing to transparency, accurate documentation, and proper coding, dental practices protect themselves while strengthening the profession as a whole.

Top Illegal Dental Billing Practices to Watch For

Illegal dental billing practices vary in complexity. Some are subtle errors that slip through during busy clinical days, while others are intentional acts of fraud that take advantage of the insurance system.

Regardless of motive, these practices can expose a dental office to serious legal, financial, and ethical consequences. Understanding these billing violations in depth is the first step toward preventing them.

Below are some of the most significant and commonly investigated billing violations in dentistry, why they occur, and how they impact both providers and patients.

1. Upcoding

Upcoding occurs when a provider charges for a higher-paying procedure than what was actually performed. It is one of the most frequently flagged forms of dental billing fraud because it directly inflates reimbursements.

For example, a dentist might perform a simple extraction but bill it as a surgical one, even though no flap, sectioning, or advanced surgical step was involved. Or a routine prophylaxis is coded as scaling and root planing without clinical justification such as periodontal pocket measurements, X-rays, or documented periodontal disease.

Upcoding isn’t always intentional. It may stem from inexperienced billers doing documentation or people who don’t fully understand CDT and ICD-10 codes. However, insurers treat it as a serious violation. When patterns of upcoding are detected, especially for high-revenue procedures like crowns, periodontal treatments, or endodontics, insurers may initiate audits that place the entire practice under scrutiny.

At I-Med Dental Solutions, we routinely find that upcoding stems from two main causes: lack of training and improper documentation. This is why structured documentation protocols and regular chart-to-code audits are non-negotiable for compliance.

2. Unbundling

Unbundling happens when a provider bills the individual components of a bundled service separately in order to collect higher total reimbursement. Many CDT codes are designed to encompass multiple steps in a single code, but some practices split them to maximize revenue.

For example, a comprehensive procedure such as a full mouth debridement or a root canal includes several components like anesthesia, diagnostic imaging, and various procedural steps. Billing each of these individually, when guidelines dictate a single comprehensive code, constitutes unbundling.

Some offices mistakenly believe this is allowed because “each step was performed.” However, the rule is not about what happened clinically; it’s about how the service is defined contractually between insurers and providers. Unbundling is one of the quickest ways to trigger payer audits because insurers track patterns over time.

Advanced and careful revenue cycle management can help dental practices stay safe from issues like unbundling. At I-Med Dental Solutions, our claim validation process automatically flags such claims.

3. Billing for Services Not Rendered

Also known as Phantom billing, another illegal dental billing practice, that involves creating and pushing claims for reimbursement against services that were never rendered. It can include billing for X-rays that weren’t taken, fluoride treatments not applied, or sealants that were not placed.

Sometimes this issue arises from rushed workflows, for example, a template autopopulating services a patient normally receives but didn’t receive during a specific visit. In other cases, it is a deliberate attempt to inflate revenue.

Regardless of intent, insurers treat phantom billing as a red-flag violation. Practices that do this may be liable for repayment, fines, and, in extreme cases, face criminal charges. The best protection is maintaining synchronized clinical records and billing claims. If a service isn’t documented, it should never be billed.

4. Misrepresenting Dates of Service

Changing or manipulating dates of service may sound like a minor adjustment, but it is a serious compliance violation. Some practices alter dates to fit treatment within coverage periods or bypass waiting periods. Others may adjust dates to avoid frequency limits or year-end benefit caps.

A common example occurs with crowns, a dentist might bill the crown preparation date instead of the cementation date because the prep date falls into the patient’s coverage period, but guidelines often require billing based on the seat date.

Insurance companies are quite strict when it comes to claims with suspicious times and dates. Suspicious time and date on the claim for treatment or diagnosis, even if the procedure was accurate, means a fraudulent activity, and insurance companies aren’t lenient on it. Internal controls and accurate timestamped charting are crucial in preventing these mistakes.

5. Misrepresenting the Provider

Another problematic area is billing for treatment under the wrong provider’s information. This typically happens when an out-of-network or uncredentialed provider performs treatment but the claim is submitted under a different dentist’s NPI to meet network requirements.

This practice is sometimes rationalized internally as “helping the patient get their coverage,” but insurers and regulators view it as deception.

For example, if a locum dentist covers for the primary provider, the claim must reflect that locum’s NPI, not the owner’s. Similarly, if a specialist performs a procedure in a GP office, the claim must accurately list the treating provider.

Accurate provider identity is a core compliance rule; misrepresenting it can result in insurance contract termination, recoupments, or sanctions. At I-Med Dental Solutions, our systems ensure provider IDs are validated before claims are submitted.

6. Waiving Co-payments Improperly or Routinely

Waiving a patient’s financial responsibility might seem like a kind gesture, especially for patients with financial hardships, but insurers often view routine waivers as fraud. When a dentist bills the insurer for the full amount but does not collect the patient’s share, the claim misrepresents the true financial transaction.

Improper waivers create distorted pricing, artificially inflate reimbursements, and violate contractual agreements with insurance companies. A waiver may be allowed under specific, documented circumstances, for example, proven financial hardship, but not as a general policy or marketing tactic.

Practices should have standardized financial hardship guidelines and proper documentation to avoid this issue.

7. Duplicate Billing

Duplicate billing occurs when the provider submits a claim for a procedure twice. Irrespective of the intent of the provider or the dental billing company, this act of billing twice is considered a severe violation of the law.

Duplicate claim submission or billing for the same treatment on the same day is:

  • When the dental office submits a claim again without waiting for the payor’s official verdict on a claim, i.e., approval/reimbursement or a denial
  • When multiple staff members send duplicate claims on the same day
  • If there’s a system glitch responsible for triggering repeated submissions

Many insurance companies operating in the USA use cutting-edge processes for detecting duplicate claims. If their automated tools suspect repeated occurrences, they flag it as a duplicate claim.

Dental clinics and third-party dental billing companies must be very careful when tracking claims. It helps them avoid manual overlap and unintentional duplication, which results in loss of revenue for them and lost credibility for the provider.

8. Exaggerating Conditions or Misdiagnosing to Justify Treatment

Some billing issues arise from documentation that doesn’t support the clinical necessity of a procedure. When a diagnosis does not align with the treatment provided, for instance, billing for periodontal therapy without charted perio measurements, insurers may classify it as fraud.

In many states, dental practitioners often exaggerate diagnoses to claim more revenue against treatments. This not only violates billing laws but also puts patients at risk by recommending unnecessary care.

Accurate diagnosis, clear documentation, and alignment between clinical findings and billed procedures are non-negotiable components of ethical dental care.

9. Failing to Disclose Dual Insurance Coverage

When a patient has more than one insurance policy, practices must correctly coordinate benefits. Submitting claims to both insurers as if each is primary is a form of fraud that results in double payment.

Most insurers cross-check claims with national databases and detect conflicts quickly. Improper handling of dual insurance can lead to audits, recoupments, and contract violations.

Practices should always verify:

  • the primary insurance
  • the secondary insurance
  • the coordination of benefits rules

At I-Med Dental Solutions, we handle these verifications to ensure compliance and eliminate billing errors.

10. Kickbacks and Financial Incentives for Referrals

Although less common in small dental practices, kickbacks still occur in the industry. This includes offering or receiving financial benefits for patient referrals, partnerships, or service exchanges. Kickbacks violate federal and state anti-fraud statutes, including the Anti-Kickback Statute, and carry steep penalties.

Dentists must only refer patients when they truly need treatment and must not do so for their own financial gain. Practices should avoid any deals or arrangements that look like they reward referrals.

Notable Real-World Instances of Illegal Billing Practices

Illegal billing isn’t just theoretical. There have been real, high-profile cases and large-scale investigations:

  • Kool Smiles, a major U.S. dental chain, paid $23.9 million to settle Medicaid fraud charges for false claims, unnecessary procedures, and phantom billing.
  • According to the U.S. Medicaid data, in some states, dentists were flagged because they billed 16 procedures per child, much higher than typical usage, drawing suspicion for potential over-treatment.
  • Regulatory bodies emphasize that duplicative billing, date misrepresentation, or billing for services not rendered can lead to serious legal consequences, including fines, audits, and referral to law enforcement.

Identifying Illegal Dental Billing Practices

For Patients

If you’re a patient, you might not always catch billing fraud, but there are red flags to watch for:

Surprising Bills

You might notice something is off if the bill you receive doesn’t match what the dentist explained. Sometimes patients see charges for procedures they don’t even remember getting, and that’s a clear reason to take a closer look.

Inaccurate or Inflated Services

Another warning sign is when the services listed on your statement don’t line up with what actually happened during your visit. It’s also concerning if you’re billed more than what your insurance normally covers, especially when the dentist is supposed to be in-network.

Billing Mistakes Regarding Dates or IDs

Pay attention to small details like the date of service. If the date doesn’t match your actual appointment or the claim was filed under a different provider’s name or even another person’s ID, there may be a problem.

Duplicate Charges

Be cautious if you spot what looks like the same procedure being charged more than once. Duplicate billing can be easy to miss unless you review your statement carefully.

Refusal or Resistance When Asked for Itemized Bills

A practice should be willing to give you a detailed bill. If they refuse or make it difficult to get one, that’s a red flag that something isn’t being shared openly.

Questionable Necessity

If you’re pushed toward expensive or invasive treatment without a clear medical reason, take it seriously. When the explanation feels vague or rushed, it’s reasonable to ask more questions or get another opinion.

What to Do If Something Seems Wrong

If anything doesn’t feel right, you can ask for an itemized invoice, request your treatment records, and call your insurer to confirm what was submitted. If anything seems suspicious, immediately report it to the appropriate regulatory agency or your payor.

For Dental Practices

As a dental care practitioner, avoiding fraudulent activity and staying vigilant against malpractice helps to safeguard your dental clinic’s credibility, reputation, license, and financial integrity.

Here’s how to safeguard your practice.

Educate and Train Staff

Make ongoing training part of the routine so your team stays familiar with CDT codes, proper coding rules, and bundling guidelines. It also helps to build a culture where integrity matters.

Staff should understand not just how to code correctly but why accuracy and honesty protect the practice and the patients.

Implement Robust Internal Audits

Regularly compare charts with the corresponding bills to catch errors early. Many practices also rely on software that flags unusual patterns or inconsistencies. It’s useful to keep clinical duties and billing responsibilities separate, as it lowers the temptation or even the appearance of “creative” coding.

Maintain Accurate Documentation

Encourage same-day documentation so dates and details stay accurate. Employing automated claim-detection tools that timestamp entries helps you immensely. They help you stay safe from all kinds of changes and errors leading to practices. Whenever a treatment decision is made, record the reason behind it so the chart clearly supports the care provided.

Be Transparent About Patient Payments

As a dental specialist, avoid waiving co-pays or deductibles unless there’s a valid and documented reason. Patients should always understand what portion of the cost they’re responsible for, and that information should be communicated openly.

Use Accurate Provider Identifiers

Make sure every claim lists the correct treating provider. Billing under someone else’s ID, even for convenience, creates serious compliance issues and may be considered fraudulent.

Enforce a Referral Policy Free of Incentives

Referrals need to be based on what the patient truly needs, not on the possibility of financial gain. Keep clear, documented referral relationships so no one can misinterpret them as incentive-based arrangements.

Coordinate Insurance Coverage

Always verify whether a patient has more than one insurance plan. When they do, assign the primary and secondary coverage correctly so claims are filed in the right order and payments are handled smoothly.

Know the Law and Stay Updated

Both federal and state laws affect dental billing, and insurance contracts include their own regulations or requirements. Remember that rules and regulations can fluctuate. So, whenever something seems unclear, you must contact legal counsel.

Legal and Ethical Consequences of Illegal Dental Billing

Illegal billing is not a victimless crime. Here are some of the serious repercussions:

Financial Penalties

When billing fraud is uncovered, a practice may be required to return any overpayments and pay additional fines. In more serious cases, fraud laws can impose multiplied damages, and each improper claim may carry its own penalty, making the financial impact significant.

Loss of Licensure or Network Status

Dental boards have the authority to suspend or even revoke a provider’s license when unethical billing is involved. Beyond that, insurance companies can end their contracts with the practice, leaving the provider without access to many of their patients.

Reputational Damage

Even before a case is resolved, accusations of fraud can seriously damage a practice’s reputation. Once trust is lost, it’s very hard to rebuild, and the negative perception can linger long after the issue is addressed.

Criminal Charges and Imprisonment

If the fraud is severe, the authorities may move the case into criminal territory. Based on the severity of the situation, dental care providers may face misdemeanor or felony charges. Violations involving kickbacks can also trigger criminal cases, which carry the risk of jail time.

Operational Disruption

Investigations and audits can interrupt daily operations and require a lot of staff time and attention. During major compliance cleanups, stress levels rise, and it’s common to see increased staff turnover as the practice works to fix internal issues.
