Are You Covered For Malpractice After Leaving an Oral Surgery Practice?

Background facts

A middle-aged oral and maxillofacial surgeon, Dr. V, was in a practice partnership with his co-resident for over 10 years.  Both of them performed the full scope of the profession.  As part of their partnership agreement, they maintained professional liability, i.e., malpractice, insurance which covered both of them individually and the practice entity, on a claims-made basis.

Because of ongoing and worsening disputes about approaches to interacting with office staff, the partners agreed to split, with Dr. V to set up his own office just a few miles away; patients were appropriately notified of the change, with their patient records to be maintained by the oral surgeon of their choice.  When Dr. V did his business planning in anticipation of the upcoming change, he opted to obtain claims-made malpractice insurance from a different carrier than the current one because of receiving a better rate quote, which had a retroactive (“retro”) date on the day he opened the new office.  He did not purchase an extended reporting endorsement – better known as a “tail” – from his prior carrier because he did not think that he needed it, given that there would be no time gap between the coverage periods of the old and new policies.

Less than a year into his new practice, he received a letter from an attorney, seeking records regarding a patient, J, whom he had treated at the former office with the placement of maxillary implants, approximately a year-and-a-half earlier.  He asked his previous office’s staff to provide records to the attorney, which they immediately did.  Then, he contacted his current malpractice carrier to advise it of a potential claim, but was told that his current policy would not cover him for acts prior to the retro date; so he called his prior carrier regarding the potential claim, but was advised that the old policy provided no coverage for him, because the claim, if pursued, would not be filed while the prior claims-made policy for him was in effect and he had not purchased a tail upon discontinuation of that policy.  Dr. V quickly realized that he had no coverage in the event that the potential claim came to fruition as an actual claim.

Legal action

Shortly after receiving the dental records, J’s attorney retained an oral surgery expert to examine J, and to review and comment upon Dr. V’s treatment, and she was of the opinion that, because the implants lacked adequate parallelism and several appeared to be failing due to bone loss, they were no longer serviceable to support the bridge placed upon them, so the implants and bridge would need to be removed and replaced.  On behalf of J, the attorney filed suit against Dr. V, claiming negligence in association with his treatment.

With no insurance coverage in place, Dr. V located and retained an attorney, at his own expense.  The attorney explained to Dr. V that he would be responsible for all legal fees, litigation expenses, defense expert fees, and the amount of a pre-trial settlement or judgment from a court following trial.

Discovery and case resolution

While Dr. V felt confident in the quality of his work, and believed that his placement of the implants was fully within the standard of care, he saw legal costs piling up very quickly.  His attorney advised that Dr. V retain an expert to examine J with regard to his complaints, as Dr. V would need to have testimony on his behalf to counter the claims of the patient, now plaintiff, in order to be able to try to defend his actions and avoid a payout to J.

Dr. V faced a critical decision at this point: whether to continue defending the case through litigation, likely to lead to a jury trial, or agree to pay J an amount to be negotiated between the attorneys.  He opted for the latter, concluding that he would rather pay a certain known amount, than be faced with continuing costs with an uncertain end.  He calculated that, even if he were to be successful at a trial, the costs to get to that point might realistically match or exceed a settlement figure now, and a loss at trial would place him into a difficult financial hole.


In terms of policy types, they can be divided into two – – claims-made or occurrence.  As the names imply, a claims-made policy will provide coverage (for both defense costs and indemnification up to chosen dollar limits, meaning the amount of a settlement or a jury/court judgment) if the claim (a lawsuit or the threat of one) is made while the policy is in effect, while an occurrence policy will cover the insured if the policy was in effect at the time of the occurrence (treatment) which is asserted to have been negligent.

Tail coverage will protect a provider who is insured under a claims-made policy in situations when a claim of negligence is made after the policy has expired or been cancelled.  While there are certain circumstances where a tail might be provided free of charge – such as death, disability, retirement, or other specifically-stated policy provisions – there is usually a cost in obtaining that coverage.  Considering the definition of an occurrence policy, an oral surgeon protected by such a policy will not ever need to purchase a tail.  In this case, had Dr. V either been insured while with his partner by an occurrence policy, or if he had purchased a tail at the time he cancelled his initial policy upon leaving his partner, he would have had defense and indemnity protection when he was sued by J.

A hypothetical issue to be considered is that J might have sued the partnership in addition to suing Dr. V.  Those types of decisions are generally made by attorneys for plaintiffs, in conjunction with their clients. In that circumstance, depending upon the specific terms of that entity policy, the potential exists that coverage protection might have been in place to at least partially cover Dr. V, even after he left, so long as entity coverage remained in place after Dr. V’s departure or if Dr. V’s former partner purchased a tail on that policy.

We conclude by noting that some jurisdictional regulations or statutes might place a liability defense and indemnification burden for prior negligent acts upon the buyer of a dental/oral surgery practice.  While this might not feel even reasonably fair, practice purchasers could be encumbered with a lawsuit and all that goes with it, if the selling practitioner(s) is(are) sued for acts performed before the practice sale, regardless of when that suit is filed, as long as it is done within the applicable statute of limitations.

Professional liability insurance coverage is a very important means of protection, potentially including of personal assets, but it is also nuanced and legally complex.  MedPro staff, and insurance agents/brokers, are valuable sources of information to help guide dentists through unfamiliar waters at the times of policy purchase, threats of lawsuits, court filings of suits, and practice status changes.  Questions asked early can often prevent problems from arising later.
