Tail coverage: claims-made vs occurrence malpractice, and who pays

What is tail coverage in malpractice insurance?

Malpractice coverage comes in more than one form, and the difference is the trigger: the event that decides whether a given claim is covered.

A claims-made policy generally responds when the care at issue was delivered after the policy's retroactive date and the claim is both made and reported while the coverage is in force, with the specifics governed by the policy language itself. So you leave a job, the policy ends, and a patient files a claim a year later. That claim may fall outside the reporting period of the policy you had.

Tail coverage is the reporting extension purchased when the policy ends, and it is what addresses that gap. The other route is prior acts coverage from your next carrier, which covers the earlier work from the receiving side. Another reporting arrangement may apply, depending on the policies involved.

Claims-made vs occurrence malpractice coverage

Occurrence coverage responds to care delivered while the policy was active, no matter when the claim arrives, even years after you have left. Claims-made coverage responds only when the claim is made and reported while the policy is in force, which is why leaving a job can leave a gap and why tail coverage exists to fill it.

Occurrence is simpler for the clinician and usually costs more. Claims-made is cheaper up front but makes the tail question essential. Neither is wrong. The problem is not knowing which one you have.

Why the gap matters: claims arrive slowly

Malpractice claims surface and resolve over years. One study found that physicians spend, on average, nearly 11 percent of a 40-year career with an open, unresolved malpractice claim (Seabury and colleagues, Health Affairs, 2013). A claim about care from your last year at a job can easily arrive after you have moved on.

The underlying exposure also differs by specialty and by role. A study in the New England Journal of Medicine documented how differently the probability of a claim runs across specialties, and a 2025 analysis compared malpractice risk across nurse practitioners, physician associates and physicians directly. Liability is a whole care team subject.

How much does tail coverage cost?

The price is set by the carrier for your actual policy. One state regulator's guide puts tail at as much as one and a half to three times the annual premium. Rather than estimating from a remembered number, get the actual quote for the actual policy, ideally before you sign the contract that decides who pays it.

Who pays for tail coverage?

The employment contract decides. It may assign the cost to the employer, to the departing clinician, or say nothing at all. Where the contract is silent, the allocation is simply unresolved, and that is a question for qualified local counsel to settle before signature rather than after departure. Four arrangements appear in these contracts:

• The employer carries the tail on termination for any reason, in writing, with no repayment terms attached.
• A vesting arrangement, where the employer's share increases with years of service.
• The employer carries it if they terminate without cause, or the incoming employer's prior acts coverage bridges the gap.
• The departing clinician carries it in every case, or the contract says nothing. Both need attention before signature.

Picture two colleagues and one sentence

Which arrangement serves a specific clinician turns on repayment terms, tax treatment, prior acts coverage, specialty and the circumstances of departure.

Picture a colleague three years into her first attending position who decides to move closer to family. She gives notice, then reads the tail sentence for the first time. Her policy is claims-made, the extension is a separate purchase priced by the carrier, and her contract assigns that cost to the departing clinician. Nobody hid the sentence. She never asked the document the right question.

Now picture a colleague who caught the same sentence before signing and raised it during the offer discussion. She leaves the same job with the employer carrying the tail. Same clause, different reader.

Questions to ask before you sign or leave

Pull the declarations page and the employment agreement together and answer these in the documents' own words:

• Is my policy occurrence or claims-made, and what is the retroactive date?
• What are the per-claim limit and the annual aggregate? They are two different numbers.
• Who pays for tail coverage, under which departure circumstances, and is it in writing?
• Does my next carrier offer prior acts coverage?
• Do I have consent-to-settle rights, and are moonlighting, telehealth and volunteer work covered?
• Is there excess coverage above the primary policy, and at what attachment point?
