This post discusses the schemes used by employees to steal from a dental practice. The schemes are not specific to dentistry and are used to steal from every profession and business.
I have uncovered these schemes countless time since 2004, and from that, I can say that most dental embezzlement is perpetrated using a handful of common schemes.
These embezzlement schemes listed below are not “trade secrets” either. All of these schemes can found online and in the news. Visit this link to read hundreds of news articles about dental embezzlers and the schemes they used -> Find an Embezzler
BUT FIRST, LET’S BUST SOME DENTAL EMBEZZLEMENT MYTHS
“PREVENTION IS NEARLY IMPOSSIBLE”
“THERE ARE Over 300 ways to steal”
An excerpt from “Recognizing the Signs of Embezzlement” by David Harris
Yet the safeguards many dentists rely on may provide a false sense of security, according to Harris. Most practice management software programs come with defenses designed to prevent embezzlement, but Harris believes prevention is nearly impossible, so these defenses usually fall short.
David Harris, CDA Essentials Vol 2 #8:
“Ultimately, the safeguards built into these systems aren’t terribly effective, because a thief has lots of options,” he says. “We’ve catalogued over 300 ways to steal, and we’re not done!”

“300 WAYS TO STEAL” IS FALSE.
CLICK HERE TO FIND OUT WHY “300 WAYS TO STEAL” IS A MISLEADING MYTH.
Fraud methods are not discrete items, they are variations of the same handful of root causes.
In any operational environment, theft occurs through a limited set of mechanisms.
Dental embezzlers use the same schemes, and there are :
- Skimming or Cash Larceny
- Skimming
- Fraudulent Disbursements (Billing)
- Check Tampering / Billing Schemes
- Payroll Fraud
- Corruption (Kickbacks)
- Financial Statement Manipulation (rare)
Everything else is a variation or sub‑technique of these core categories.
Calling every variation a “new way to steal” is like claiming there are 300 ways to run a red light because you can do it in 300 different cars.
Fraud typologies are counted by categories, not by imaginative permutations.
“300 ways” is unmeasurable and unverifiable
A legitimate statistic must be:
- countable
- repeatable
- independently verifiable
“300 ways to steal” meets none of these criteria.
There is no industry body, academic institution, insurer, regulator, or forensic standard that recognizes such a number. It is not published, peer‑reviewed, or benchmarked. It is simply a marketing claim dressed as expertise.
When someone says, “We’ve catalogued 300 ways,” the immediate question should be:
According to what taxonomy? What methodology? What peer review?
There is no answer, because the number is rhetorical, not empirical.
If “300 ways” were true, the same logic would apply to every industry, and it doesn’t
Banks, pharmacies, law firms, and hospitals all face insider‑risk environments. None of them claim “hundreds of ways to steal” because professionals in those fields understand that:
- fraud methods cluster tightly
- controls eliminate entire clusters at once
- counting permutations is meaningless
If the dental sector truly had 300 unique, irreducible theft methods, it would be the most fraud‑complex industry in North America. It isn’t.
“300 ways” contradicts how internal controls actually work
Internal controls don’t need to block 300 hypothetical schemes. They need to block the conditions that make those schemes possible:
- unrestricted access
- lack of oversight
- absence of reconciliation
- no audit trail
- one person controlling the entire revenue cycle
When these conditions are corrected, the “300 ways” collapse into a handful of blocked pathways. The number is irrelevant because the vulnerabilities—not the creativity—are what matter.
The claim is designed to create fear, not clarity
“300 ways to steal” is not a forensic insight.
It is a sales tactic: inflate the threat, declare prevention impossible, and position oneself as the only expert who can navigate the chaos.
Smart readers can recognize this pattern immediately. It’s the same rhetorical move used in cybersecurity fear‑marketing: exaggerate complexity to imply that only a specialist can save you.
Busting Other DENTAL Embezzlement Myths
It’s a common myth is that “employees can only steal cash“.
This is perhaps supported by a false belief that checks, credit cards, and other forms of payment are “safe harbors”.
Fact is, dishonest employees can target all forms of payments
See a Typo or an Error? Report it.
Here are the most common ways to steal:
- stealing insurance payments (checks, virtual credit cards)
- stealing patient payments (cash, checks, credit cards)
- unauthorized credit/debit card refunds (to their own card)
- submitting fraudulent dental claims and stealing the payments
- issuing phony refunds to patients and insurance
- payroll padding – phantom employees
- credit card abuse
- check fraud
Add these to this list of stolen items:
- stealing rebates
- stealing dental supplies and then selling them online
- NO2 tank depletion (filling balloons with nitrous after hours)
- prescriptions / medications (anxiolytics, opiates)
- fraudulent Amazon orders – Click here Read More
- Stealing gift cards intended as incentives for patients – the office manager ordered $30K in gift cards in one year. She kept $25K of the gift cards for herself and gave $5K to patients.
- stealing office equipment
- stealing from other employees and patients
..and some dishonest employees kept on stealing after they were gone.
- One dental embezzler made the practice pay for her health plan for a full year before it was caught.
- Another embezzler stole during her employment and after. Six months after her employment ended, the ex-employee set up an automated monthly withdrawal of $600+ from the dentist’s bank account. It took many months before the practice owner noticed the ACH withdrawals. When he contacted the bank, they refused to reimburse the dentist for any unauthorized withdrawals greater than 30 days.
- An ortho manager stole dozens of postdated checks for monthly ortho payments and then suddenly quit. Three months later, she began cashing the checks. The orthodontist was tipped off when a patient complained that the office had cashed 3 of her monthly ortho payment checks all at once.

How to steal from Patients and Insurance Companies
When a dishonest employee decides to steal a payment, they often use one or more of these methods to conceal their theft .
Deleting Transactions
I’ll use cash in this example. Cash is easy to steal, easy to conceal and every dishonest employee will take cash from the practice at some point.
(Side-note: the amount of cash that a dental practice collects is idiosyncratic to the patient base. Some offices collect less than 1% of their total revenue in cash, others as much as 70%. For most general dental practices, the amount will fall between 2% and 6%)
Here is an illustration of a typical cash scheme:
- the patient has finished treatment and is at the front desk.
- the employee informs the patient there is a balance owing
- the patient makes a cash payment and the employee records the payment in the dental software
- the employee prints a receipt and hands it to the patient
- the patient leaves
After the patient has left, the employee deletes the original cash payment from the software and pockets the cash.
To conceal this theft, and to make the patient’s account appear in balance, the employee will do one of these things:
- delete the underlying treatment charge, or
- apply an unauthorized adjustment to offset the treatment charge, or
- back-date the original payment
looking for DELETED AND BACKDATED transactions
Your practice software management software has an audit log which can help you identify deleted payments, deleted treatments, and backdated records.
That said, most dentists find Audit Trail reports difficult to understand.
That is not surprising. It takes time, effort and regular use to become proficient in interpreting the various events recorded in the audit trail.
Why is an Audit Trail so important?
The Audit Trail is a valuable tool for detecting discrepancies in billing and payment entries, and uncovering instances of fraudulent activity within the office.
The audit trail tracks modifications, deletions, and date changes made to patient and financial data, as well as changes to appointments, and provider allocations.
In essence, the audit trail can help to identify whether a financial discrepancy was the result of an unintentional human error, willful neglect, or malicious intent.
When you see a deleted or backdated payment, begin by asking yourself if there may be a reasonable explanation. I do not recommend confronting the employee to look for answers, that may worsen the situation.
If you need help, most dental software companies offer online videos and manuals to help you better understand what is in the audit log.
If you have questions about your audit trail, feel free to drop me a line.
spot check for phantom adjustments
Dishonest employees can apply offsetting ‘phantom’ adjustments to patient ledgers to create the illusion of balance. They often will choose a frequently used adjustment to conceal their theft. (i.e.: enter a fictitious adjustment instead of the actual payment)
For example, in a PPO practice that accepts insurance reimbursement, it is common to see legitimate writes-off of non-covered services using various codes such as “Insurance Adjustment” or “Insurance Write-off”. Over time, there will be hundreds of legitimate adjustment recorded in various patient ledgers.
But because the legitimate adjustment code is ubiquitous in the reports, it will be less likely for a fraudulent adjustment to stand out amongst the hundreds of other legitimate adjustments.
Credit adjustments such as “Professional Courtesy” or “Seniors Discount” may be used less frequently by a dishonest employee since it may draw unwanted attention from the owner. (i.e.: a seniors discount applied to a Gen-Y (millennial) patient account will stand out)
writing OFF OLD UNPAID BALANCES
Fraud experts agree, the more authority a person has, the more damage they can do.
Employees should not be permitted to write-off unpaid accounts. The office should have a written policy regarding write-offs with all write-offs approved by the practice owner on a monthly basis.
Stated differently, what’s to stop a dishonest employee from pocketing a long overdue payment when the employee knows the patient may never return.
Take the case of Kyle.
Kyle owed the practice $800 for well over a year. The office manager has sent monthly statements, with no success.
Then, one day, “out of the blue” Kyle walks into the practice to pay his bill. Kyle apologizes for being so late with his payment and tells the office manager he has been out of work for a long time and is relocating for a new job out-of-state.
Kyle pays his bill by credit card and leaves. The office manager knows that Kyle will not be returning to the practice, so she deletes the credit card payment from Kyle’s ledger, and replaces it with a write-off. Then, she refunds $800 to her own credit card.
At day end, everything appears in balance and the office manager feels confident that the practice owner will never question the write-off on an old unpaid account.
Back-dating is one of the oldest schemes AND still used today.
Here’s how backdating works:
As an illustration, a patient’s ledger shows there was a visit and charge entered on on March 1, and the patient paid the account balance in full on March 20.
Looks legit – or is it?
With backdating, this is what really happened.
The patient was charged on March 1 but paid the account on March 26. (the patient did pay on March 20 as the ledger shows)
The dishonest employee back-dated the patient payment for March 26 to make it appear as though it was paid six days earlier on March 20.
The employee pocketed the payment and because of backdating, the payment did not not show up on the normal day end report for March 26.

Cash payments are usually stolen on the same or next day.
Patients who pay in cash usually do so after their appointment has ended and before they leave the practice.
If the patient’s appointment was over at 11:00am, then we should expect to see a cash payment recorded proximate to 11:00am (5 to 10 mins after the appointment ended)
If your audit log shows cash payments being recorded at times long after the the appointment has ended, this may be a sign of “cash holding”.
This happens when an employee sequesters cash payments during the day and then later decides how much cash they can steal without getting caught.

SUBMITTING FALSE insurance CLAIMS.
Dishonest employees will can also steal from insurance companies to line their own pockets (but not all steal for themselves)
Here is a common scheme.
The employee creates a fake a dental claim for treatments that were not rendered, and submits the claims it the insurance company for reimbursement.
When the insurance check arrives in the mail, the employee converts the check to cash by one of two methods.
They deposit the check into the dentist’s account and at some time, remove an equal amount of cash (substitution scheme) or the check is deposited into the employee’s account (depositor forgery).
Despite the check being payable to the dentist, an employee can convert the check to cash by depositing the check directly into their own bank account through an ATM.
Sometimes, an employee will collude with a patient (most likely a friend or family member) to steal from the insurance company.
The employee sends in fraudulent claims and the insurance checks mailed to the patient. The patient cashes the check and then shares the proceeds with the employee.
“One of my first cases involved collusion between an employee and a patient. The employee submitted fake claims for the patient’s family and the checks were mailed to the patient . The insurance company paid $43,000 to the patient for work that was never done. The employee cashed the checks and split the money with the employee.”

Stealing insurance CHECKS
Dishonest employees can also steal insurance checks for work that was actually done and deposit the checks into their own account.
Many practice owners find this hard to believe, yet I see this all the time. Want to see how easy it is to steal insurance checks?
Watch the video of Arica Cameron who stole $600,000 in insurance checks and deposited them into her Wells Fargo account.
DEPOSIT TAMPERING
In every dental office, someone must physically take the cash and checks* to the bank. This person will have an opportunity to take a portion of the money before it is deposited into the dentist’s account.
*practices that use check scanners for remote deposit make fewer trips.
Separation of function will reduce the risk of deposit tampering. In this example, someone is assigned to prepare the bank deposit slip for the bank and a different employee is assigned to make the physical deposit. The employee who made the deposit keeps a copy of the slip which is matched to a receipted deposit slip issued by the bank when the deposit is made.
Separation of function is designed to prevent deposit tampering but thefts still occur because the process is not adhered to.
In many dental offices, a single person oversees preparing the deposit slips, making the deposit, and reconciling the bank statement. That person can steal money and conceal it by falsifying the deposit slips.
To illustrate, if a dentist was paid $1,000, and the employee filled out a deposit slip for $500 and stole the other $500. The employee also made corresponding bogus entries to understate the day’s receipts.
Again, the embezzler’s goal is to create a false sense that everything is in balance.
The best way to deter this kind of fraud is to separate the functions of preparing the deposit and making the deposit.
Stealing from the dentist’s deposit will be difficult to conceal for a long time if separation of function exists.
Deposit tampering can be successful for a long time when a practice owner has no interest in the business side of the practice and trusts one employee to look after all things.
