Key takeaways
- Claims-made coverage stops answering for your past work the day the policy ends, unless someone buys a tail or the next policy picks up prior acts.
- Occurrence coverage follows the date of treatment, so there is nothing to buy when you leave.
- In a practice sale, the tail is a closing item with a price, and the purchase agreement should say who pays it.
- Associate and employment agreements should assign the tail before anyone resigns, not after.
- A buyer should see declarations pages, retroactive dates, and loss runs before closing.
Most providers pick a malpractice policy once, early in their career, and never think about the form again. Then the practice goes under LOI, or an associate gives notice, or you take a job with a group, and someone asks a question nobody planned for: who is covering the last ten years of patient care once this policy ends?
The answer depends on one line in the declarations page. Your policy is either claims-made or occurrence, and that choice decides whether a sale or a departure comes with a bill. I see it come up in dental, veterinary, med spa, physician and optometry deals, usually later in the process than it should.
Claims-made vs. occurrence in plain terms
An occurrence policy covers incidents that happen while the policy is in force, regardless of when the claim is filed. If you treated a patient in 2024 under an occurrence policy and the claim arrives in 2028, the 2024 policy responds, even if you canceled it years ago.
A claims-made policy covers a claim only if the claim is made, and usually reported, while the policy is active, and only for incidents after the policy’s retroactive date. Once the policy ends, claims about your past work have nowhere to land.
Two add-ons close that gap:
- Tail coverage, formally an extended reporting period (ERP), lets claims about past work be reported after the claims-made policy ends.
- Nose coverage, or prior-acts coverage, is the new carrier agreeing to keep your old retroactive date, so the new policy picks up your earlier work.
When a claims-made policy ends, one or the other is needed. Not both, and not neither.
| Claims-made | Occurrence | |
|---|---|---|
| What triggers coverage | Claim made and reported during the policy | Incident during the policy |
| Early-year premium | Usually lower, steps up over several years | Usually higher from the start |
| When the policy ends | Need a tail or nose coverage | Nothing further to buy |
| Key date to check | Retroactive date | Policy period |
| Deal impact | Tail becomes a negotiated cost | Little to allocate |
Why claims-made becomes a deal issue
Claims-made policies are common because they are cheaper in the early years. The deferred cost shows up when the policy ends, and a practice sale ends a lot of policies at once.
The tail is usually priced as a multiple of the expiring annual premium and generally has to be purchased within a short window after the policy ends. Some carriers provide a free or reduced-cost tail on death, disability or retirement, often with conditions on age and years with the carrier. Sellers who are stopping clinical work commonly read that provision before assuming they will pay full price. If you are selling and continuing to practice for the buyer, the retirement tail may not apply at all.
The coverage also sits in different places depending on the profession. Dentists and physicians often hold individual policies, with the practice entity on a separate policy or endorsement. Veterinary professional liability is frequently bundled into the practice’s business package. Med spas usually carry coverage at the entity level, with separate questions about the medical director and each injector. In each case, the first job is to list every policy that touches patient care and note which ones are claims-made.
Selling or buying in the next year? Bring your declarations pages to a confidential consultation and I will walk through what ends at closing and what needs to be bought.
Who pays the tail when a practice is sold
In an asset purchase, the buyer is generally not assuming the seller’s liabilities. That is the point of the structure. But patients do not read the purchase agreement. A buyer who now owns the same office, the same phone number and the charts can still end up named in a claim about care the seller provided, even if the buyer has a defense.
So the question in an asset deal is less about legal liability and more about whether coverage actually exists for pre-closing care. Who pays to make sure it does is negotiable. A common starting point is that the seller pays for the tail on the seller’s own work and on the selling entity’s policy, because that coverage protects the seller first. Buyers sometimes agree to share the cost, or to secure nose coverage under their own policy, as part of the price conversation.
In a stock or membership-interest purchase, the entity comes with its history. Incidents from before closing belong to an entity the buyer now owns, so the buyer has a direct interest in either a tail on the entity’s prior policy or prior-acts coverage on the new one.
Transition periods add a wrinkle. If the seller keeps treating patients for a year after closing, the seller’s post-closing work needs coverage under the buyer’s program, and the seller’s pre-closing work still needs a tail or nose. Those are two different policies solving two different problems.
When an associate or employed provider leaves
The same issue repeats every time a provider leaves a group practice on claims-made coverage. If the practice’s policy covered the associate, someone has to buy a tail for the associate’s work, or the associate’s next employer has to pick up prior acts.
Employment and associate agreements tend to handle this one of three ways: the practice always pays, the provider always pays, or the payer depends on how the relationship ends. The trigger-based version is common in practice, for example the practice pays if it terminates without cause, and the provider pays on resignation or termination for cause. Some agreements phase the provider’s share down with years of service.
Any of those can work. What does not work is silence. An agreement that never mentions the tail leaves the question to be argued during a resignation, which is the worst moment to negotiate anything. A buyer should also read every associate agreement in diligence, because the buyer inherits those tail promises if the agreements are assigned.
What a buyer should check in diligence
Buyers commonly ask for the actual documents, not a summary from the broker:
- Declarations pages for every professional liability policy, individual and entity, for the last several years
- The policy form for each, so you know which are claims-made and which are occurrence
- Retroactive dates, and whether any gap exists between policies
- Loss runs from each carrier, which show reported claims and incidents
- A written statement of any known incidents, complaints or board matters not yet reported as claims
- Every associate and employment agreement, with its tail provision flagged
- Confirmation of coverage for hygienists, technicians, injectors and other non-owner clinicians
A gap in retroactive dates matters more than most buyers expect. It means a stretch of past care that no policy may cover.
What to put in the deal documents
A short checklist for the purchase agreement and related documents:
- Coverage covenant. The seller will buy a tail of a stated duration for each claims-made policy, or deliver proof of nose coverage, by closing.
- Proof at closing. The ERP endorsement or carrier confirmation is a closing deliverable, not a post-closing promise.
- Cost allocation. Who pays, stated as a fixed sum, a share, or a credit against the price.
- Rep on insurance and claims. The seller represents the policy types, retroactive dates, and that all known incidents have been disclosed and reported.
- Indemnity tie-in. Pre-closing professional liability is a seller indemnity item, and the escrow or holdback is sized with it in mind.
- Transition coverage. If the seller keeps working, the employment or independent contractor agreement states who insures that work.
- Associate agreements. Assigned agreements are reviewed for tail obligations, and the price reflects any the buyer is taking on.
FAQ
Do I need tail coverage if I have an occurrence policy? No. Occurrence coverage responds based on when the treatment happened, so claims about care during the policy period are covered after the policy ends.
What is the difference between tail and nose coverage? A tail is bought from your current claims-made carrier to extend reporting after the policy ends. Nose coverage is the next carrier taking on your earlier work by keeping your retroactive date. Either solves the same gap.
Who usually pays for the tail when a practice is sold? It is negotiated. A common starting point is that the seller pays for the seller’s own pre-closing coverage, but cost sharing and credits against the price are both seen.
Can I switch from claims-made to occurrence before I sell? Sometimes, but switching does not cover past work. A tail or nose is still needed for the years on the claims-made form.
Malpractice coverage is one of the few deal items with both a hard deadline and a real price, and it belongs on the closing checklist from the start.
