Reading time: 8 minutes

Accurate and thorough record keeping is one of the most protective actions an oral and maxillofacial surgeon (OMS) can take in their practice. In this case study, a patient agrees to a procedure for the extraction of tooth #17. At a follow up visit, the patient complains to the operating OMS of numbness on her lower lip. A year later, the patient sues the OMS, claiming ongoing numbness and a lack of informed consent. The Dental Board evaluates whether the chart entry is sufficient to meet appropriate standards.

Background Fact

Dr. B has been an oral and maxillofacial surgeon in his solo practice for nearly 3 decades, in which he makes all chart entries by hand, unwilling to use electronic records as most of his colleagues had been doing as of long ago. On a typical day in the office, he received a telephone call from a referring general dentist, asking Dr. B to see a healthy 21-year-old woman, R, who was in pain due to a pericoronitis overlying a soft tissue-impacted lower left third molar. Dr. B agreed to evaluate the patient as soon as she arrived. Upon R’s arrival, she completed a health history form in the waiting room, as well as various other documents.

Within a few minutes, R was taken for a panoramic radiograph, and then seated in a surgical operatory. Dr. B examined R, both clinically and radiographically, and determined that tooth #17 was a candidate for extraction, with R agreeing to proceed that day. Because she did not have an empty stomach, the procedure would be performed under local anesthesia. Dr. B went through a detailed informed consent process with R, culminating in R signing a “surgical consent form” which set forth all of the risks, benefits, and alternatives that had just been discussed with her. Dr. B specifically pointed out in discussion that the roots of tooth #17 appeared radiographically to lie in close proximity to the inferior alveolar nerve canal. He explained the potentially permanent associated paresthesia risk to R, in words that she clearly understood, as well as placed a circled asterisk next to that written risk on the consent form, which was kept in R’s chart.

Following the administration of local anesthesia, and allowing it time to take effect, Dr. B efficiently and routinely extracted tooth #17, without sectioning or bone removal, after which he placed a single suture which was to be removed in a week. Dr. B made the following handwritten chart entry: “ext STI 17 w/l.a., BSS x1, ret 1 week for SR, Ibuprofen 400 q4h prn.” When R returned for her suture to be removed, she complained that she felt profoundly numb on the left side of her lower lip. Dr. B reminded R of their pre-surgical discussion. Throughout the course of 4 monthly follow-up assessment visits, there were no signs of improvement, after which R never again returned.

Legal Action

Nearing a year following surgery, a process server came to Dr. B’s office and handed him a Summons and Complaint, through which Dr. B learned that R was suing him for oral surgical malpractice in causing her ongoing numbness, and for failing to obtain her informed consent. Dr. B immediately reported this to his professional liability carrier, which placed him in contact with defense counsel assigned to defend him. The litigation process had begun.

Through all discussions with his attorneys, and by way of his deposition testimony, Dr. B was steadfast in his views that the tooth was in need of extraction, that he had made no errors in his surgery, that the inferior alveolar nerve injury was a result solely of the tooth’s anatomic relationship with that nerve, and that he had obtained R’s informed consent via a thorough back-and-forth discussion which was memorialized in a signed writing. Counsel for both R and Dr. B retained expert oral and maxillofacial surgeons to testify as to their respective opinions at trial. Dr. B exercised his policy’s consent provision and refused to agree to attempts at settlement, moving the case forward to trial.

Trial and Beyond

In front of a judge and a jury, both sides presented their cases. R’s expert contended that Dr. B’s surgery had been unnecessary, arguing that the pericoronitis could have been calmed down with a course of antibiotics, and maintained with regular dental hygiene visits and periodic antimicrobial mouth rinses. The expert also put forth R’s contention that Dr. B had merely glossed over and minimized these alternative treatment options, thereby invalidating the informed consent process. Dr. B and his expert explained to the jury that the suggested alternatives were simply “temporary fixes” that would have ultimately been unsuccessful, eventually resulting in an absolute – and potentially emergent – need for the extraction at an older age, when the process would have been more difficult. The defense expert eloquently educated the jury about the fact that decisions about surgery come down to weighing the high probability of a positive outcome against the much lower likelihood of a known risk coming to pass, a process which was demonstrated “on signed paper” to have been fully considered by R.

In under an hour of deliberation, the jury unanimously returned a verdict in favor of Dr. B, on the claims of both oral surgery malpractice and lack of informed consent. Dr. B was, for obvious reasons, thrilled about the outcome. But R became angry, feeling as though she had been deprived of compensation that was due her. After discussing with her attorney the possible options she then had, she ruled out an appeal because of her attorney’s advice that her chances of success by that route were quite low and would cost a significant amount of money. But she was “all in” regarding filing a complaint with the state’s Dental Board, and submitted a formal complaint against Dr. B, simply claiming that he had caused her harm by virtue of his negligent oral surgery treatment.

With the help of his defense attorney, continuing to represent him pursuant to the terms of his malpractice policy, Dr. B provided the Board with a copy of his records and a detailed explanation of what he did and why, much as he had at trial. Dr. B appeared multiple times at Board proceedings, accompanied by his counsel, and responded to many questions, most of which focused on the quality and completeness of his office chart entries for R.

The Board issued a set of findings against Dr. B, requiring that he pay a substantial fine and take 10 hours of continuing education on the subject of recordkeeping, with a record of that discipline to be posted on the state’s licensing website. The thrust of the Board’s sanctions was that, even though there was no evidence that he had acted improperly regarding the extraction or that he had provided R with inadequate information with which she could make an informed decision, Dr. B had failed to comply with the state’s very specific strict standards of recordkeeping. The Board described in detail that Dr. B had violated the recordkeeping statute by: failing to make a chart entry that provided a diagnosis serving as the basis for treatment; failing to describe the surgical procedure performed in the detail required; failing to state a prognosis for R’s potential recovery from the nerve injury at any post-operative visit; failing to record R’s vital signs before surgery; failing to record the amount and type of local anesthesia given; and failing to document that a doctor-patient discussion had taken place to explain the contents of the signed consent form.

Takeaways

It is well-known by and often discussed among oral surgeons that the specter of being sued for dental malpractice – by patients who have undesired surgical outcomes – exists. But it is far less often considered that patients might file complaints against them with state Boards, either in conjunction with filing lawsuits or as stand-alone actions. As a matter of self-protectiveness, it is prudent to also understand the realities that Board actions carry: while Dr. B celebrated his trial success, that celebration was short-lived, only to be followed by what might be legitimately viewed as a far more serious chain of events. Most professional liability policies provide legal defense for Board actions, but few, if any, indemnify (“protect financially”) for fines meted out by those Boards.

The March 2025 issue of JADA featured an article by Dr. Yen-Wen Huang, et. al., which analyzed many Dental Board disciplinary actions in Texas, albeit against general dentists. That review concluded that the highest infraction group cited was for inadequate recordkeeping, accounting for 39% of all occurrences of misconduct, well exceeding those groups that were clinically based. These results stand as a stark reminder of the importance of recordkeeping in the course of practice. It is a very fair assumption that Dental Boards see it that way.

Addressing the specific areas of deficiency pronounced against Dr. B, and blending them together, a sound lesson to be learned is that the subsequent readers of Dr. B’s chart – here, the Board members – were unable to discern the details of significance of Dr. B’s treatment of R, simply by reading his chart. Oral surgeons, as well as all practitioners, are obligated to know and meet the statutory requirements for recordkeeping of the state(s) in which they practice, lest they might be subject to discipline in the event of a patient complaint to a Board, even for issues unrelated to charting.

Finally, we touch briefly on electronic health records (EHRs), a topic related and seemingly relevant to the issues discussed here. Many EHR software programs contain templates for commonly performed procedures. Those templates are best seen as starting points – not end points – for recording patient interactions, subject to modification so as to accurately and completely state what took place for the particular patient. Savvy plaintiffs’ attorneys will use a one-size-fits-all template to aggressively cross-examine, often times succeeding in damaging a surgeon’s credibility, based solely upon a single inaccurate or overly generalized chart note. Dental Boards and juries have no objective way to assess the actions of a defendant oral surgeon by any means other than an evaluation of the chart entries. They matter a great deal.

Background facts

R was a 61-year-old generally healthy man who had worn maxillary full dentures for years, but was becoming increasingly dissatisfied with them, both functionally and esthetically. His lower arch posed no problems for him: other than a 3-unit fixed bridge on the right and a 4-unit bridge on the left, he had natural teeth in place. In the past, he was a nearly pack-a-day smoker, but he had since overcome that habit. He presented to a multispecialty dental office he had seen advertised locally, seeking to improve the condition of his maxilla.

He initially saw a prosthodontist, who evaluated the mouth and concluded that an implant-supported prosthesis would work well for R. Per office policy, the on-site oral surgeon would handle the implant aspect of treatment, with the patient then returning to the prosthodontist for the restoration. That same day, the OMS, Dr. G, met with R, ordered a CBCT study, reviewed it, and discussed the available options. Because of the paucity of maxillary bone — especially posteriorly — and "low-lying" maxillary sinus cavities, a traditional implant arrangement would not be possible. So, 2 options were available: (1) perform bilateral sinus lifts with bone grafting, allow for an adequate healing period, place 3 implants (potentially) on each side, and then restore the maxilla prosthetically after osseointegration; or (2) do an all-on-4 procedure using the pterygoid bones bilaterally for both posterior implants, place a provisional prosthetic appliance that same day, and later convert to a permanent prosthesis after integration.

The office management encouraged the most time-efficient case completions possible. With that in mind, Dr. G and the prosthodontist discussed the available options, with Dr. G expressing some concern about the radiographically appearing rather thin pterygoids, particularly on the right side. However, the prosthodontist did not want to wait for the entire sinus lift process to play out, and encouraged the OMS to do the all-on-4 approach, despite her stated concerns. Dr. G (reluctantly) agreed, and so did R, after they had a full discussion about the most common risks, benefits, and options, with R signing a consent form.

On the day of treatment, R took the oral sedative prescribed for him by Dr. G, just before leaving home. Dr. G injected local anesthetic solution buccally and palatally across the entire upper jaw. Because she is left-handed, Dr. G began with her preferred side, the left, because access was easier. Referring to the CBCT images, she uneventfully placed 2 implants on the left side, 1 at the approximate site where tooth #11 had been, and 1 angled into the pterygoid: both were clinically stable. She then turned to the right side to place 2 implants before the prosthodontist placed the ready provisional. The implant near the prior site of the upper right canine was smoothly placed. In performing the right pterygoid osteotomy, Dr. G's concern came to fruition, as the bur, which had initially been met with typical bony resistance, suddenly fell into a void, which she presumed to be the pterygopalatine fossa. When she backed out the handpiece, bright red, pulsating blood heavily flowed into the mouth, clouding the entire field.

Her initial approach was to pack the site with gauze strips, which did slow the flow, but the gauze quickly filled with blood and continued to do so despite repeated packing. Dr. G believed that she had pierced into (a branch of) the right maxillary artery. With her being unable to gain hemostatic control, and being in an outpatient setting with an awake patient, she attempted to gain access to the source of the bleed by entering the maxillary sinus through a Caldwell-Luc approach, and then cutting a window through the posterior sinus wall to enter the fossa. But doing so only provided a second outlet of significant bleeding, leading her to conclude that ligating the artery required in-hospital care by a head and neck surgeon. R was transported by ambulance to a nearby medical center, with Dr. G accompanying him to try to maintain site pressure as they travelled. R was emergently taken to the OR, where he was induced and intubated, and where an ENT surgeon unsuccessfully attempted access to the torn vessel endoscopically, ultimately ligating the vessel some 2 hours later by way of a preauricular approach infratemporally. R remained in hospital for a week, and missed work for more than a month, left with a scar and always feeling limitations to his usual exercise routine.

Legal action

R's newly retained attorney obtained all of the relevant dental and medical records, and sent them on to an academic-based OMS for review. That expert passed on his conclusions to the attorney who hired him: that Dr. G succumbed to external pressures and performed a procedure that she knew was concerning and risky, given the specific anatomy presented, and that the preferred set of procedures for this patient would have begun with the sinus lift and graft approach. The attorney also contacted the treating ENT, who was willing to provide his opinion that the bleed and the resultant surgery and after-effects were due to an ill-conceived surgical treatment plan by Dr. G.

Dr. G contacted her malpractice carrier when she provided records to R's attorney, and again when she was served with papers that initiated the lawsuit against her. She had personally been deeply upset by the events, now some months ago, and she told her assigned attorney that she was eager to put this behind her, partly for the personal impact but also because she realized that she had not exercised her best judgment.

Settlement moves began quickly, with an agreement reached before discovery even started. In addition to money, which covered medical costs, physical and emotional distress, and lost income, R made a somewhat unusual request: that Dr. G write an apology and explanation to him, which he felt that he needed to close the chapter. Despite her attorney advising Dr. G against doing so, explaining the potential impacts upon a Board complaint (which never happened) or hospital credentialing, she did as R had asked, because she, too, needed the closure.

Takeaways

Pressures are frequently placed on practitioners, including oral surgeons, from sources as diverse as patients, dental or medical colleagues, and practice supervisors and owners. The reasons for the responses to those pressures are equally diverse, from the need to maintain employment, to conflict aversion, to ego. In the end, though, all that really matters on the legal side of practice are adherence to standards of care and principles of ethics. Perhaps, a safe approach for practitioners to take is that if something simply does not feel right, stay away from it. While that might not always be practical, it can at least be an internal starting point, if not ultimately the end point.

It is the general rule, rather than the exception, that there are most often multiple options/alternatives to overcome dental and surgical problems. Principles of informed consent dictate the requirement to advise patients of, among other things, available alternatives. But that does not mean every alternative, only the viable ones. And if an alternative is not viable for any reason, whether because of patient anatomy, underlying patient medical conditions and social habits, or provider limitations (based upon ability or experience), that alternative falls out of the realm of informed consent. Here, the anatomy of R's right pterygoid and, perhaps (reading between the lines) her own limitations, Dr. G seemingly knew that an all-on-4 plan was not viable for R. Fighting her better judgment was a clear factor in the events and injuries.

All procedures carry risk. It is part and parcel of healthcare delivery, particularly when surgery is involved. Practitioners appropriately take specific risks into account when weighing the potential coming to fruition of those risks against the benefits of doing the procedure. There is no one-size-fits-all formula to use to come to a decision, but instead a subjective process that is individual to every surgeon, considering a host of factors. Many risks come to pass (in the form of injury) in the absence of any negligence, with that concept being a foundation for much of malpractice defense, but when injuries occur because of negligence, that often becomes the very basis for plaintiffs' cases against doctors.

Decisions about settlement versus trial are extremely case-specific, with the insurer, counsel, and all litigants playing significant roles. Practitioners who have "pure consent" policies are permitted, per policy language, to withhold consent to a settlement, in favor of going to trial. But in cases where practitioners do provide their consent to settle, that does not mean that the malpractice carrier must then settle the case, but simply that it may agree to a settlement. Think of it as a permission slip, but not a requirement slip.

Summary of takeaways

External pressures should never outweigh clinical judgment when determining the most appropriate treatment plan.
Not every treatment option is suitable for every patient — anatomy, provider experience, and overall risk must be carefully evaluated before proceeding.
When complications occur, treatment decisions that fall outside the standard of care can increase liability exposure and lead to malpractice claims.

In this real-life case study, dentists will see how a billing dispute and incomplete informed consent process escalated into a malpractice lawsuit. Learn why clear communication about treatment risks, accurate coding practices, and thoughtful handling of patient concerns are essential to reducing liability and protecting patient trust.

Background facts

For Dr. A, extracting teeth was an everyday part of practice, as was virtually the entire scope of dentistry. In addition to postdoctoral training, she had been performing these procedures for years in a region of the state with no oral surgeons within a 2–3-hour drive. She was a participating provider in several dental insurance plans that were popular among her patients.

One such patient, P, was an 18-year-old high school senior who presented for an annual recall visit, with a new complaint of periodic pain associated with the lower right third molar. Despite P being of majority, his mother accompanied him into the treatment room to see Dr. A. Following a clinical examination, a panoramic film was taken and viewed by Dr. A. Tooth #32 was erupted, had incomplete apex formation, but was still in close radiographic proximity to the inferior alveolar canal. Dr. A assessed the pain to be a function of difficulty in cleansing the area, with inflamed gingivae as a result. She suggested, while pointing to the panoramic, extraction, which she said, "shouldn't be too hard,” although it carried a "slight risk of a nerve injury which could leave P's lower lip and chin numb, and rarely be permanent." This conversation was documented with specificity in the chart. P had heard about impacted wisdom teeth from a few friends, so he asked whether his tooth was impacted. Dr. A replied, "No, it is not.” P wanted to think about it, so he left the office with a sample of an oral rinse and instructions as to how to improve his oral hygiene. A month later, the symptoms persisted, so P's mother called the office to schedule an extraction appointment.

Before having local anesthetic injected, P was handed a paper entitled "consent form,” which he and his mother "briefly read.” The document contained a list of potential risks, including a general statement about possible "loss of sensation.” P signed the document prior to the extraction going forward. Dr. A worked on the tooth for well over an hour, much longer than she had anticipated, cutting out pieces of tooth and trimming away bone using round and fissure burs. P could taste blood, particularly at one point, which caused Dr. A to pack gauze in his mouth. The following day, P awoke to find the right half of his lower lip and chin numb, which he did not find surprising, given the warning beforehand, but so was the right half of his tongue, which was a surprise. At post-op visits, Dr. A assured and re-assured P and his mother that feeling would return to normal — it never did.

Separately, P received a bill for Dr. A's services from her billing office, seeking a co-pay for "#32 7240.” The amount was significant, despite Dr. A's advertised plan participation, so P's mother questioned the office manager as to what all of this meant. The response was that, according to the insurance plan's rules, Dr. A was permitted to charge that amount for fully impacted wisdom teeth, as this was. P's mother replied that Dr. A had specifically advised her and her son that the tooth was not impacted, no less fully so. The office manager spoke with Dr. A, but the answer came back that, because Dr. A had to work so long to remove the tooth, she was not willing to make any adjustments.

P's mother contacted the insurance carrier to explain the situation. The carrier requested a pre-treatment radiograph from Dr. A, based upon which the in-house reviewers concluded that the tooth was not appropriately coded as 7240, but rather should have been 7210 (surgical extraction of erupted tooth). Under the plan provisions, Dr. A was therefore not permitted to charge any co-pay but instead accept the plan payment in full. When the insurer notified Dr. A of that, with a copy sent to P's mother (whose employer provided the coverage), Dr. A was steadfast that she was entitled to the amount billed and would send P to collection if she was not paid. P's mother did pay the claimed balance, but the carrier dropped Dr. A from the panel due to what it referenced as "upcoding resulting in excessive billing.”

Legal action

P had slowly been adapting to the lip, chin, and tongue numbness, but his mother remained upset about the principle of billing her son and threatening a collection action, so she contacted an attorney. The attorney was not very familiar with dentistry in any legal regard, so he reached out to his own dentist, with a copy of Dr. A's records that he had been provided, to help him interpret what was going on. The dentist agreed with the insurance company's position that the extraction had been inappropriately upcoded, but perhaps more importantly that it was clear from the records that, while P had been warned of the possibility of an inferior alveolar nerve injury and its effects, he had not been told anything about tongue numbness, which came from an injury to an entirely different nerve branch and which should have been avoided if proper technique had been employed.

The attorney initiated a lawsuit against Dr. A, asserting lack of informed consent relating to the lingual nerve injury, dental malpractice regarding the causing of the lingual nerve injury, and breach of contract leading to the improperly billed (and collected) co-pay amount. The defense attorneys assigned to Dr. A by her malpractice carrier reviewed the case with their client and advised her that they would seek expert opinion as to the substance of the informed consent and malpractice claims, but that she would not be covered for the breach of contract claim, per a clearly stated policy exclusion.

The expert retained by Dr. A's counsel was provisionally willing to present a defense as to the malpractice claim regarding her having negligently caused the tongue numbness, but that position would need to be re-evaluated following her deposition testimony. However, there was no evidence in the record to demonstrate that she had provided any warning of a potential lingual nerve injury and its impacts. The defense expert did not see a pathway to successfully defend the claim of lack of informed consent. A second expert reviewer reached the same conclusion.

Dr. A's attorneys had a candid discussion with her. Even if the malpractice claim could likely be effectively defended, the lack of informed consent claim could not. So, P would be entitled to a monetary award regardless of which, or both, of the claims went P's way in the eyes of a jury. Dr. A agreed to have her attorneys seek to settle the claim, to be paid by the malpractice carrier, which they did. As part of the settlement agreement, Dr. A would personally return to P the amount his mother paid her for the co-pay.

Takeaways

While it is impossible to know whether P would have sought an attorney at some point to file an action on his behalf based upon the substantive dental issues, it is quite clear that the issue which drove the initial attorney involvement was the billed, and eventually paid, co-pay amount. There is then perhaps a bit of irony that the money that Dr. A was unwilling to waive directly led to a settled malpractice claim, but that insisted-upon co-pay not only started the legal action steps but was also ultimately paid by Dr. A out-of-pocket. Dr. A made the decision to demand a disputed amount of money, and that decision likely cost her far more — particularly with her being dropped from a panel — than had she acquiesced in the first place. It is not our role here to advise dentists as to whether they should fervently go after unpaid, disputed fees. Instead, we demonstrate a situation where doing so ended up causing more harm than benefit. Food for thought.

Experience teaches that lay jurors might not always understand scientific, dental facts, sometimes making their determinations counter to what experts and attorneys anticipate. On the other hand, issues relating to overbilling or upcoding are relatively straightforward for plaintiffs' attorneys to explain to jurors, and simple for them to understand. At times, jurors might put all else aside and render a verdict for a plaintiff if they do not see the defendant-dentist as having been honest. Such is a version of jury nullification, with the jury members substituting what they deem critical in place of what the law says is critical. Taking subjectivity of that type out of the hands of juries increases a defendant's chances for success.

This case study exemplifies how the trigger for a patient seeking legal counsel might have nothing at all to do with the quality of dentistry. Yes, dentistry is complex, and there is an ever-present unpredictability factor, so ideal results do not happen with every procedure, with every patient. What need not be complex are matters over which dentists and their staff members have full control — such matters can virtually always be taken out of the equation as to what starts the legal ball rolling.

Finally, we briefly address the coding of procedures for billing purposes. The ADA and perhaps other associations provide numerical codes for dental procedures, which state the procedure performed and which often serve as the basis for which payment is sought and made. With few exceptions — such as 7241 for full impactions with unusual surgical complications, or time under sedation/general anesthesia, as examples — procedure codes do not take into account the length of time required to complete or the difficulty in doing so. To upcode to a procedure not actually performed, for a higher fee, is to invite a host of problems, including the initiation of a malpractice lawsuit or Dental Board complaint.

Summary of takeaways

A signed consent form alone is not enough — patients should be informed of all risks associated with a procedure, and those discussions should be thoroughly documented.
Billing disputes and inaccurate procedure coding can damage patient trust and may become the catalyst for malpractice claims.
Upcoding procedures can result in payer disputes, loss of network participation, regulatory concerns, and increased legal exposure.

Background facts

For Dr. C, an oral and maxillofacial surgeon, extracting teeth was an everyday part of practice. As the only oral surgeon within a 2–3-hour drive, she was a participating provider in a number of dental insurance programs which were more popular within her patient and referral bases.

One such patient, T, was an 18-year-old high school senior who self-presented based upon a network list, with a new complaint of periodic pain associated with the lower right third molar. Despite T being of majority, his mother accompanied him into the treatment room to see Dr. C. Following a clinical examination, a panoramic film was taken and viewed by Dr. C.

This state did not require specialty-specific experts. The dentist agreed with the insurance company's position that the extraction had been inappropriately upcoded, but perhaps more importantly that it was clear from the records that, while T had been warned of the possibility of an inferior alveolar nerve injury and its effects, he had not been told anything about tongue numbness, which came from an injury to an entirely different nerve branch and which should have been avoided if proper technique had been employed. (As a side note, the general phrase in the consent form, "loss of sensation,” did not provide any expert reviewer with the specificity that is helpful in a defense.)

The attorney initiated a lawsuit against Dr. C, asserting lack of informed consent relating to the lingual nerve injury, dental malpractice regarding the causing of the lingual nerve injury, and breach of contract leading to the improperly billed (and collected) co-pay amount. The defense attorneys assigned to Dr. C by her malpractice carrier reviewed the case with their client and advised her that they would seek expert opinion as to the substance of the informed consent and malpractice claims, but that she would not be covered for the breach of contract claim, per a clearly stated policy exclusion.

The expert retained by Dr. C's counsel was provisionally willing to present a defense as to the malpractice claim regarding her having negligently caused the tongue numbness — but that position would need to be re-evaluated following her deposition testimony. However, there was no evidence in the record to demonstrate that she had provided any warning of a potential lingual nerve injury and its impacts. The defense expert did not see a pathway to successfully defend the claim of lack of informed consent. A second expert reviewer reached the same conclusion.

Dr. C's attorneys had a candid discussion with her. Even if the malpractice claim could likely be effectively defended, the lack of informed consent claim could not. So, T would be entitled to a monetary award regardless of which, or both, of the claims went T's way in the eyes of a jury. Dr. C agreed to have her attorneys seek to settle the claim, to be paid by the malpractice carrier, which they did. As part of the settlement agreement, Dr. C would personally return to T the amount his mother paid her for the co-pay.

Takeaways

While it is impossible to know whether T would have sought an attorney at some point to file an action on his behalf based upon the substantive oral surgery issues, it is quite clear that the issue which drove the initial attorney involvement was the billed, and eventually paid, co-pay amount. There is then perhaps a bit of irony that the money that Dr. C was unwilling to waive directly led to a settled malpractice claim, but that insisted-upon co-pay not only started the legal action steps but was also ultimately paid by Dr. C out-of-pocket. Dr. C made the decision to demand a disputed amount of money, and that decision likely cost her far more — particularly with her being dropped from a panel - than had she acquiesced in the first place. It is not our role here to advise oral surgeons as to whether they should fervently go after unpaid, disputed fees. Instead, we demonstrate a situation where doing so ended up causing more harm than benefit. Food for thought.

Experience teaches that lay jurors might not always understand scientific, dental/surgical facts, sometimes making their determinations counter to what experts and attorneys anticipate. On the other hand, issues relating to overbilling or upcoding are relatively straightforward for plaintiffs' attorneys to explain to jurors, and simple for them to understand. At times, jurors might put all else aside and render a verdict for a plaintiff if they do not see the defendant-dentist as having been honest. Such is a version of jury nullification, with the jury members substituting what they deem critical, in place of what the law says is critical. Taking subjectivity of that type out of the hands of juries increases a defendant's chances for success.

This case study exemplifies how the trigger for a patient seeking legal counsel might have nothing at all to do with the quality of surgery performed. Yes, oral surgery is complex, and there is an ever-present unpredictability factor, so ideal results do not happen with every procedure, with every patient. What need not be complex are matters over which surgeons and their staff members have full control; such matters can virtually always be taken out of the equation as to what starts the legal ball rolling.

Summary of takeaways

A billing dispute can quickly escalate into legal action, even when the original concern is not directly related to clinical care.
Accurate coding matters because upcoding or disputed fees can damage patient trust and increase liability risk.
Clear, specific informed consent documentation helps support a stronger defense if complications occur.

Summary of takeaways

External pressures should never outweigh clinical judgment when determining the most appropriate treatment plan.
Not every treatment option is suitable for every patient — anatomy, provider experience, and overall risk must be carefully evaluated before proceeding.
When complications occur, treatment decisions that fall outside the standard of care can increase liability exposure and lead to malpractice claims.
