When a large healthcare operation faces non-renewal of a professional and general liability program written on an occurrence basis, it confronts what may be the most consequential technical distinction in liability insurance: the difference between a policy that responds to when the injury happened and one that responds to when the claim is made. In a soft market the distinction is academic. In a hard market for healthcare liability, it is the difference between a placement and a declination.
An occurrence policy covers incidents that take place during the policy period, whenever the claim is eventually brought. For long-tail classes — nursing homes, addiction treatment centers, medical providers — this is enormously valuable, because claims routinely surface years after treatment. A claims-made policy, by contrast, covers claims first made during the policy period, subject to a retroactive date. It is cheaper for carriers to price, because the tail of future claims on expired years stays with whoever insured those years, and it is therefore often the only form the market will offer a distressed class.
The insured’s insistence on occurrence form is rational. Moving from occurrence to claims-made mid-stream creates a structural gap: future claims from past occurrences must be picked up by tail coverage or by the retroactive date of the new form, and mishandling either transition point can leave years of exposure uninsured. The tail itself is expensive — frequently 150 to 250 percent of the expiring premium — and the buyer’s leverage to negotiate it is weakest precisely when the incumbent has non-renewed.
But rationality and availability are different things. When the market for a class contracts, the question shifts from “which form do we prefer” to “what will any credible carrier write, and how do we bridge the transition safely.” That bridge work — extended reporting period negotiations, retroactive date alignment, prior acts coverage, careful reading of the new form’s claim-definition wording — is unglamorous and absolutely load-bearing. Accounts have been technically insured on both sides of a transition and practically uninsured in the middle.
The broader lesson is about sequencing. Form conversion is easy when it is voluntary and brutal when it is forced. Buyers in long-tail classes do well to treat the occurrence form as an asset with a maintenance cost — and to watch their carrier’s appetite signals early enough that a conversion, if it must happen, happens on their terms rather than at the point of a non-renewal letter.
