Claims-Made vs. Occurrence Malpractice — and Why Tail Coverage Matters

The ADA's own guide to dentist employment agreements defines the trigger precisely: a claims-made policy "requires that both (i) the incident giving rise to the malpractice claim and (ii) the report of the claim occur while the policy is in force." Miss either half — say, the claim surfaces after you've switched jobs or insurers — and the policy doesn't respond.

An occurrence policy skips that problem entirely: it covers an incident based on when the treatment happened, not when the claim is later filed.

That single structural difference is why claims-made policies are the ones that create a "tail" problem when you leave a job, and occurrence policies don't.

Play it out: you treat a patient in year one of a job, leave for a new practice in year three, and the patient discovers a problem and files a claim in year five.

Under an occurrence policy from that first job, the claim is still covered — it's written to the treatment date, not the report date, so it doesn't matter that you've since moved on.

Under a claims-made policy from that first job, it isn't covered — unless you're still enrolled in that same policy (unlikely, since you've since moved to a new employer's plan) or unless someone bought tail coverage to extend its reporting window after it ended.

Malpractice claims routinely surface years after the treatment that prompted them, which is exactly the gap a claims-made policy leaves open once you've left.

Tail coverage exists to close the exact gap a claims-made policy creates.

Per the ADA's guide, "if a claim is filed after the dentist's policy has expired (or properly terminated), no coverage would be provided unless the dentist purchases an extension of the policy known as 'tail' coverage."

In practice, that means every time you leave a job where you were on a claims-made policy — switching employers, moving from an associate role to ownership, or retiring — there's a decision to make about that gap.

If nobody buys tail and a claim later surfaces for care you gave under that expired policy, there's no coverage for it.

Employment agreements don't automatically say who's on the hook for tail when you leave.

The ADA's guide frames this as something an employee-dentist should pin down up front: whether they have "the right (and at what cost) to procure (or have the employer procure) 'tail' coverage."

That's two separate questions worth resolving before you sign an associate contract — do you have the right to buy tail if the practice or its insurer won't, and, separately, who is actually paying for it.

A contract that's silent on both can leave a departing associate to cover it alone, at whatever the insurer charges at that moment.

Not every exit requires paying for tail out of pocket.

The ADA's guide notes that "'tail' coverage is generally expensive, but some insurance policies may provide free 'tail' coverage in the event of death, disability, or retirement."

Whether your policy includes that exception — and how it defines "retirement" or "disability" — is a policy-specific detail, not something to assume.

It's worth confirming directly with your insurer or broker, and revisiting the point at contract renewal or before a planned career change, since it materially changes what a transition costs you.

The ADA's own guide is explicit that it does not set a benchmark: "The ADA does not offer set guidelines as to appropriate limits of liability." It goes on to note, as a market observation rather than a recommendation, that as of 2020 "many leading insurers... market policies of $1 million per occurrence and $3 [million] yearly aggregate limits to general dentists."

That figure describes what insurers were commonly selling at the time the guide was written — it is not a standard, a minimum, or advice about what you should carry.

Coverage needs vary by state, specialty, and practice setting, and the only way to size a policy correctly is with an insurance broker or attorney who can assess your specific situation.

Malpractice terms are one piece of a larger employment agreement, alongside how you're paid and any non-compete clause you're asked to sign.

Before agreeing to anything, confirm: whether your policy is claims-made or occurrence; if claims-made, who has the right to buy tail and who pays for it; and whether your policy includes a free-tail exception for death, disability, or retirement.

These are exactly the kind of contract terms worth having reviewed by a healthcare attorney before you sign — not after a claim surfaces years into a job you've already left.

This article summarizes general information from the ADA's public guide to dentist employment agreements, which states it does not constitute legal or professional advice and notes that the law varies by jurisdiction. It is not legal advice. Malpractice policy terms, contract obligations, and state requirements vary by insurer, employer, and state and change over time — review your policy and any contract with an attorney before you sign or let coverage lapse.
