Malpractice & Tail Coverage for Locums
By Cory Kleinschmidt
Locum agencies almost always provide malpractice coverage as a standard contract term. What varies is the type, occurrence or claims-made, so confirm which one you’re getting in writing. Claims-made without tail is the gap that can follow you for years after you leave.
Malpractice is the one insurance question that outlasts the work itself, because claims can surface long after the care. The model usually handles it. The exception is where the risk hides, so knowing the difference is the whole point of this guide.

Do Locums Need Their Own Malpractice Insurance?
Usually not for the work itself, because the agency or facility provides coverage as a standard term of the contract. What you need to do is verify the type and limits in writing before you start, not assume.
Many clinicians still carry a small personal policy for work outside their primary opportunities (moonlighting, side shifts, license defense), because an agency’s policy protects you only for the work it covers. That’s a personal risk decision, not a locum requirement.
Occurrence vs Claims-Made: What’s the Difference?
Occurrence coverage protects you for any incident that happened while the policy was active, no matter when the claim is filed. Claims-made coverage only protects you if the policy is still active when the claim is filed. That timing gap is the entire issue, because malpractice claims often surface years after the care.
| How it works | Occurrence | Claims-made |
|---|---|---|
| What it covers | Incidents that happened while active | Claims filed while active |
| Claim filed after policy ends | Still covered | Not covered without tail |
| Tail needed when you leave | No | Yes, unless someone buys it |
| Who it’s simplest for | The departing locum | Whoever keeps the policy active |
With occurrence coverage, you can finish the work, move on and still be covered if a claim arrives in three years. With claims-made coverage, the day the policy ends, so does your protection for past work, unless you buy tail.
What Is Tail Coverage and Who Pays for It?
Tail coverage (formally, an extended reporting endorsement) extends a claims-made policy so you can still be covered for claims filed after the policy ends, for incidents that happened while it was active. It exists to close the gap claims-made coverage leaves when you leave.
Two things to know. First, tail is expensive: it commonly runs about twice the annual premium as a one-time cost. Second, on a locum contract, who pays for tail should be spelled out before you sign. When the coverage is occurrence-based the question is moot, which is exactly why occurrence is the locum-friendly form.
Get the occurrence-versus-claims-made answer in the contract, not on a phone call.
How Do You Verify What an Agency Actually Provides?
Ask three questions in writing before you sign:
- Is the policy occurrence or claims-made?
- What are the per-claim and aggregate limits?
- If it’s claims-made, who pays for tail?
Standard limits in medical settings are commonly $1 million per claim and $3 million aggregate, though higher limits appear for higher-risk work. If a recruiter can’t answer the occurrence-versus-claims-made question, that’s a signal to slow down.
How Much Does Locum Malpractice Cost?
When the agency provides it, nothing comes out of your pocket. When you buy your own policy, cost depends heavily on your profession, specialty, state and limits, so treat any single figure as directional rather than a quote. As a rough map of the landscape (individual annual premiums, directional):
- Nurse practitioners: roughly $900 to $2,000, with a median solo policy near $1,332.
- Physician assistants: broadly comparable to NPs, often about $1,700 to $2,650 at standard limits, higher for surgical or high-risk scope.
- CRNAs: the highest of the APP professions, commonly $4,000 to $10,000 or more for 1099 and independent work, higher for a high-risk case mix, because of the anesthesia risk class.
- Physicians: the highest overall, from a few thousand for low-risk specialties to $30,000 to $100,000-plus for high-risk surgical specialties in litigious states.
One locum-specific point across all of these: self-employed and 1099 rates run higher than employed rates for the same clinician. Nurse practitioner data show self-employed premiums 23% to 59% above employed, which matters if you’re buying your own policy. Premiums you pay yourself are deductible; see 1099 taxes.
How This Differs for NPs, PAs and CRNAs
The policy mechanics are identical for everyone. The premium is what changes. The direction is consistent even when the exact dollars aren’t: physicians highest, CRNAs next and well above the other APPs, NPs and PAs lowest and roughly comparable.
CRNAs carry anesthesiologist-adjacent risk, so their band sits far above NP and PA. The AANA offers part-time and 1099/locum policy forms built for exactly this kind of work. See the CRNA guide.
NPs and PAs land in a similar, lower band; the exact ordering between them isn’t clean and varies by specialty and state. See the nurse practitioner guide and physician assistant guide.
Scope and supervision terms belong in the contract, not the malpractice math. See reviewing a locum contract.
Key Takeaways
- Agencies almost always provide malpractice coverage. What varies is occurrence versus claims-made, so confirm the type and limits in the contract.
- Occurrence covers incidents by when they happened; claims-made only covers claims filed while the policy is active.
- Tail closes the claims-made gap and commonly costs about twice the annual premium, one time. Occurrence coverage needs no tail.
- Verify three things in writing: occurrence or claims-made, the per-claim and aggregate limits and who pays for tail.
- Premiums rise physicians, then CRNAs, then NPs and PAs. Self-employed rates run higher than employed for the same clinician.
Frequently Asked Questions
Do locum agencies provide malpractice insurance?
Almost always, as a standard contract term. What varies is whether the policy is occurrence or claims-made, so confirm the type and limits in the contract before you start.
What’s the difference between occurrence and claims-made?
Occurrence covers incidents from when they happened regardless of when the claim is filed; claims-made only covers claims filed while the policy is active.
Who pays for tail coverage on a locum job?
It should be defined in the contract. With occurrence coverage the question doesn’t arise, which is why it’s the locum-friendly form.
How much is tail coverage?
Commonly a one-time cost of about twice the annual premium.
Do CRNAs pay more for malpractice than NPs?
Yes. CRNAs carry the highest APP premiums due to anesthesia risk; NPs and PAs are lower and roughly comparable.
