The flagged procedure families
Two decades of dental False Claims Act settlements, OIG audit work, and CMS dental Medicaid guidance repeatedly identify a short list of procedures. Many are higher-value services that can be difficult to assess after a tooth has been capped, filled, or extracted:1
If utilization analytics identify an outlier dentist or office in one of these procedure families, review a sample of the underlying records. Payers and relators’ counsel are likely to examine the same patterns.
The prohibited patterns
Upcoding
Billing a higher-level or more expensive code than the service rendered and documented supports. A common dental example is reporting a simple extraction as surgical. Surgical extraction usually pays more, and the distinction depends on clinical facts such as sectioning, bone removal, or flap elevation that should appear in the record. The ImmediaDent and Dental Dreams MassHealth settlements addressed routine extractions billed as surgical.2 The test: does the documentation support the code? If a coder reading only the note and the radiograph would not arrive at that code, the code is wrong.Unbundling
This occurs when a practice bills separately for component services covered by one comprehensive code, such as billing components of a completed procedure alongside the procedure itself. Payers publish bundling logic in their processing policies, and the All Smiles orthodontic settlement addressed “unbundled” dental Medicaid claims.6Misattributed provider numbers
Dental groups have a violation family that medicine sees less of: claims naming a dentist who did not perform the work. Both the MB2 and HQRC settlements recited claims submitted under erroneous or inaccurate servicing-provider identifiers.3 This often starts as an operational shortcut. A new associate is not yet credentialed with a Medicaid dental benefit administrator, so the office submits claims under the owner’s number “until enrollment completes.” Those claims identify the wrong provider. A related problem arises when unlicensed personnel perform work billed under a dentist or hygienist, creating both scope-of-practice and billing risk. Complete the required enrollment, credentialing, and affiliations before billing. See Credential new dentists.Documentation and signature failures
Services must be documented, and documentation must be authenticated by the rendering dentist. Unsigned notes, notes signed by someone who did not perform the service, and cloned documentation copied between encounters are all findings. Copy-forward in the PMS is a specific risk: a note that records identical findings in identical language across six recall visits does not evidence six distinct examinations.Radiographic documentation
Images play an unusually important role in dental medical-necessity review. A crown may require a pre-operative radiograph showing the condition. SRP needs periodontal charting and, under many payer policies, radiographic evidence of calculus or bone loss. A surgical extraction record must support the surgical approach. The HQRC admissions, for example, addressed whether radiographs showed decay reaching the required depth for pulpotomies.3 When the payer’s policy calls for radiographic evidence, the radiograph should predate and support the procedure. Internal reviewers should compare the image with the claim just as a payer auditor would. A practice that cannot produce required diagnostic-quality images faces a documentation and compliance issue as well as a denial risk. See Dental attachments.Medical necessity
The service must also meet the payer’s coverage and medical-necessity rules. Dental Medicaid standards appear in state program manuals and benefit-administrator criteria; commercial dental payers publish their own processing policies. A procedure may be performed and coded correctly yet remain nonpayable for a particular indication or frequency. Medical necessity was central to several pediatric Medicaid matters discussed above.Billing for services not rendered
The clearest violation. Kool Smiles’ settlement included pulpotomies never performed; MB2’s included fillings never placed.3 It also includes billing for no-shows as if seen and billing under a dentist who was not present.The False Claims Act
The reason billing compliance carries the weight it does. The FCA, 31 U.S.C. §§ 3729–3733, prohibits knowingly submitting false or fraudulent claims to the government. “Knowingly” includes actual knowledge, deliberate ignorance, and reckless disregard. Specific intent to defraud is not required.7 Damages are trebled, plus a civil penalty per claim. Because dentistry bills procedure-by-procedure at Medicaid piece rates, a systematic pattern across two years produces an enormous claim count and a penalty exposure independent of the actual overpayment.Production compensation is scienter evidence
Dental FCA matters show how compensation and performance management can become evidence of knowledge or causation. The Kool Smiles settlement recited allegations that clinics pressured dentists to meet production goals, rewarded “productive” dentists, disciplined “unproductive” dentists, and ignored internal overutilization complaints. The ImmediaDent settlement described production rewards, discipline for missed objectives, and personnel direction that compromised clinical judgment as part of the alleged corporate-practice violation.2 The government’s theory may focus on whether the management company caused false claims through its incentive and control systems, without proving bad faith for every individual encounter. Production quotas and clinical bonuses recur in the enforcement record and may also raise corporate-practice concerns. See DSO enforcement and risk.Qui tam
The FCA’s qui tam provisions let a private person, a relator, sue on the government’s behalf and share in the recovery. Many prominent dental-chain FCA matters began as qui tam suits brought by dentists or office staff, including former employees, billers, and managers.1 The complaint is filed under seal while the government investigates whether to intervene. For an operator, this means:- Your dentists and billing staff are the people most likely to become relators, because they see everything. A dentist who raises an overutilization concern and is dismissed or ignored is the exact fact pattern DOJ recited against Kool Smiles.
- Build a channel where concerns get heard and documented. A functioning internal reporting process is both a defense and the reason most concerns never become lawsuits.
The overpayment connection
Under 42 U.S.C. § 1320a-7k(d), an identified Medicare or Medicaid overpayment must be reported and returned within 60 days; retaining it creates FCA liability. CMS revised the identification standard effective January 1, 2025, replacing “reasonable diligence” with the FCA knowledge standard.8 An identified billing error can start the repayment clock. In a Medicaid-heavy dental group, the applicable state program and its benefit administrators must be included in the response. See Report and return overpayments.Who owns billing compliance in a DSO-PC group
The two-entity structure requires a clear allocation of billing responsibility and authority. The PC owns clinical and billing compliance. It renders the services, its dentists document them, its NPI is on the claim, and it is the entity submitting claims. Compliance responsibility follows. The DSO staffs and systematizes it. The compliance officer, the auditors, the training program, and the monitoring tools are typically DSO-provided resources. Define coding and billing roles in the management services agreement (MSA). The agreement should allocate responsibility for coding accuracy, describe the DSO’s personnel and systems support, and preserve any clinical authority that state law requires dentists to retain. DSO direction over coding may create both billing and corporate-practice risk. The ImmediaDent settlement addressed related conduct, and newer state management-entity statutes identify billing or coding among functions a management company may not control.9 This creates a structural tension worth naming: the DSO has the economic incentive to maximize collections and provides the staff who code, while the PC bears the compliance responsibility. The mitigations that work:- The dentist can always reject a coding change, and that authority is documented
- Coding-audit results reach the PC, even if DSO management also receives them
- Billing staff can escalate documentation concerns to a dentist without going through DSO operations
- Compensation for billing staff is not tied to collections in a way that rewards aggressive coding
A minimum viable program
Scaled to a small group:- Written policies on coding, documentation, and billing
- Annual training for dentists, hygienists, and billing staff
- Periodic internal audits: sample charts by dentist and period, compare documentation and radiographs with billed codes, and give additional weight to the procedure families above
- A reporting channel where concerns can be raised without retaliation, and a documented non-retaliation policy
- Documented exclusion and debarment screening, with LEIE, SAM.gov, and required state lists analyzed separately and a cadence matched to applicable payer, program, state, contract, and risk requirements
- A response process for identified overpayments, aware of the 60-day clock
- A designated compliance owner, a person, not a committee
