Billing for care that never happened, describing a procedure as something more expensive, unbundling one service into several claims, routinely waiving copays, reporting incorrect treatment dates, or balance billing beyond what the payer contract allows can each cross a legal, ethical or contractual line in a dental practice — and the biller who keyed the claim is exposed alongside the office.
Here are the practices, the laws behind them, and what to do when you're asked.
Short answer
There is no single "dental billing law."
A billing practice gets its legal or ethical character from four layers, and one claim can sit under several at once: federal fraud statutes, the American Dental Association's Code of Ethics, the payer's network contract, and state law.
The statutes carry penalties.
The ADA Code binds member dentists professionally — it is an ethics code, not a statute.
The contract controls whatever the practice agreed to.
State law wasn't researched for this page, so treat it as an open question for anything the layers above don't settle.
The federal statutes worth knowing by name:
- False Claims Act (31 U.S.C. §3729(a)(1)). Any person who knowingly presents, or causes to be presented, a false or fraudulent claim for payment is liable for a civil penalty of $5,000 to $10,000 per claim, as adjusted for inflation, plus three times the government's damages. It reaches claims involving federal money — Medicaid claims, for example.
- Federal health care fraud (18 U.S.C. §1347). Knowingly and willfully executing a scheme to defraud a health care benefit program is a crime punishable by up to 10 years in prison — and the statute defines "health care benefit program" to include private plans, not only public ones.
The conduct itself is a short list: describing a procedure as something more expensive than what was done, splitting one procedure into several billed parts, routinely waiving copays to win patients, billing for care that never happened or wasn't needed, reporting incorrect treatment dates to obtain benefits, and billing a patient beyond what the payer's contract allows.
If you work as a dental billing coordinator, every one of those runs through your keyboard — which is why the liability section below is about staff, not just dentists.
Upcoding and unbundling
Dental claims are written in codes.
Under HIPAA, the Code on Dental Procedures and Nomenclature (CDT) — maintained and distributed by the American Dental Association — is the required standard code set for dental services (45 CFR 162.1002).
The codes change from edition to edition: the ADA's Code Maintenance Committee met on March 13, 2026 to agree the changes for CDT 2027, which is why billers work from the current year's book.
What the code set is and how it fits the job is its own topic — see CDT codes.
Upcoding is the common name for describing a procedure as something it wasn't.
The ADA's code doesn't use that word, but its provision on false or misleading representations (5.B.5) describes the conduct: incorrectly describing a dental procedure on a third-party claim form in order to receive a greater payment, or describing it so that a non-covered procedure looks covered.
Both are unethical under the code.
Unbundling — billing one bundled procedure as separate line items so the parts pay more together than the bundle would — isn't named in the ADA Code text this page reviewed, but it's the same move from the other side: the claim no longer describes the service the way the code set defines it, and the payer pays more as a result.
The honest-defense side matters.
Coding mistakes happen in both directions, and a mismatch between chart and claim isn't automatically fraud — the criminal statute's own wording is "knowingly and willfully."
The biller's protection is documentation: code what the chart supports, and when the chart doesn't support the code, that's a question to raise before the claim goes out, not after.
Copay waivers and fee games
Routinely waiving copays — writing off the patient's share to keep patients happy or win new ones — is the practice on this list with a federal rule aimed squarely at it.
Under the federal civil monetary penalties law, "remuneration" to Medicare or Medicaid beneficiaries includes the waiver of coinsurance and deductible amounts (42 U.S.C. §1320a-7a(i)(6)).
The law carves out non-routine waivers: ones that aren't advertised and are made after a good-faith finding of financial need or after reasonable collection efforts fail.
That rule is about federal programs.
For private dental plans, the ADA's ethics code carries the parallel line, and state insurance-fraud law — not researched here — may also apply.
The ADA Code (5.B.1) frames the private-plan version: a dentist who accepts an insurer's payment under a copayment plan as payment in full, without disclosing to the insurer that the patient's portion will not be collected, is engaged in overbilling.
The related fee games get their own provisions — raising a fee solely because the patient has dental benefits is unethical (5.B.2), and reporting incorrect treatment dates to help a patient obtain benefits that would otherwise be disallowed is a false or misleading representation (5.B.4).
One more federal statute sits behind the waiver question.
The Anti-Kickback Statute makes it a felony to knowingly and willfully pay remuneration — including any kickback, bribe or rebate — to induce referrals of individuals for items or services payable by a federal health care program.
It's the same "remuneration" concept the copay-waiver rule turns on, with inducement as the trigger.
Billing for services not rendered
A claim for care that never happened is the clearest kind of false claim: the service, visit or restoration on the form doesn't exist in the chair.
Under the False Claims Act, knowingly presenting — or causing to be presented — a false or fraudulent claim for payment carries the civil penalties described above, and "causes to be presented" is written broadly enough to reach the person who prepared the claim, not only whoever directed it.
The near cousin is billing for care that happened but shouldn't have.
The ADA Code (5.B.6) says a dentist who recommends or performs unnecessary dental services is engaged in unethical conduct, regardless of practice arrangement or contract.
When unnecessary treatment gets billed, the claim is accurate about what was done and misleading about whether it was warranted — and the biller is often the person positioned to notice volume that doesn't match the schedule.
Practically, this is the category where a daily habit does the most good: every line item should trace back to a chart entry, an appointment and a completed procedure.
If a code shows up on a day sheet with no chart note behind it, the question — what was done here? — belongs before submission, not after a payer asks.
Balance billing
Balance billing means billing the patient for the part of a bill the plan didn't pay.
It's the category that also draws patient-side readers, and the one this page treats most carefully, because the rules are not one-size-fits-all.
For in-network care, whether the practice may collect that balance from the patient is governed by the network contract the practice signed and by state law — and neither is cataloged here.
That means no blanket statement is available: not "in-network dentists can always bill the balance," and not "it's illegal everywhere."
The honest answer is to read the specific contract and check the specific state before collecting — or before telling a patient they don't owe.
When a patient balance lands on your desk after a plan pays, the working documents are the contract and the EOB.
The EOB shows what the payer allowed, what it paid and what it assigned to the patient — careful reading an EOB is how you know what the plan actually thinks the patient owes before anyone gets a surprise bill.
No blanket rule for in-network balance billing
Is the biller liable?
Yes — the statutes are written to reach staff.
The False Claims Act imposes liability on "any person" who knowingly presents, or "causes to be presented," a false or fraudulent claim.
The person who keys, batches or submits the claim causes it to be presented; "I was told to" is not a provision in the statute.
Criminal exposure runs in parallel: 18 U.S.C. §1347 names "whoever" executes a scheme to defraud a health care benefit program, punishable by up to 10 years in prison, and because the definition includes private plans it can apply to private dental insurance.
The criminal statute's wording is "knowingly and willfully" — the statute's own marker between a scheme and a coding mistake.
Where any specific case falls is a legal question for an attorney, not for this page.
There's a second, less obvious route into federal files: exclusion.
The federal exclusion payment ban reaches administrative and management services even when they aren't separately billable — so an excluded person working in billing, front-office or management at a practice whose services federal health care programs pay for can create liability — not only clinicians.
If you've ever been excluded from federal health care programs, that's a fact to know about yourself before taking a billing job; if you're screening candidates, it's a fact to check.
The career stakes are concrete even short of any statute.
BLS counted 15,240 billing and posting clerks inside offices of dentists in May 2025, at a median of $24.96 an hour ($51,910 a year; 10th percentile $41,690, 90th percentile $70,270) — the nearest federal series, since BLS has no occupation for the dental billing coordinator title, and the same occupation across all industries — a series that includes medical billing clerks — medians $23.32 an hour ($48,500).
DentistryHires' own listings showed 57 active dental billing and insurance coordinator listings as of October 22, 2026, with a median posted rate of $24.50 an hour among the 41 that state one (middle half $21.50 to $27.50) — advertised pay, not earnings, and a small sample.
It's a modest, specialized living, and a firing tied to a fraudulent claim is the kind of record that can follow a billing career in a small industry.
What to do if asked
Being asked to bend a claim is uncomfortable because the ask can come from the person who signs your paycheck.
The practical playbook is short: slow the claim down, get the question onto paper, and route it to the people whose job it is to own compliance.
Escalation goes to the dentist-owner and the office manager, in writing — compliance is real work somebody has to own in a dental practice, and compliance the office manager owns is part of that picture.
If you're hiring a billing coordinator instead of being one, the same list doubles as an interview script — candidates who treat these lines as hard limits should be able to describe an escalation process much like this one.
- Pause the claim. A claim that hasn't gone out can be corrected; one that has, can't be un-billed.
- Ask what in the chart supports the code. Documentation settles most disputes without anyone raising their voice.
- Get the request in writing and keep your copies: the claim as submitted or withheld, the EOB, the emails.
- Check the current CDT book when the dispute is about a code — codes change every edition, and some disputes are just stale codes.
- Escalate in writing to the dentist-owner and the office manager — the people whose job compliance actually is.
If a concern doesn't resolve inside the practice, an employment or health care attorney is the right consult when your own exposure worries you — this page is career information, not legal advice.
What's in your control day to day is simpler: submit claims the chart supports, refuse the ones it doesn't, and write down the moments you did.
