Most clinicians spend weeks researching pay rates and specialties before their first locum assignment. Very few spend the same energy on malpractice coverage — until they're facing a claim that happened to fall in a gap they didn't know existed.
Malpractice insurance is one of the most consequential logistics questions in locum tenens, and it's also one of the most commonly misunderstood. The stakes are high: a lapsed policy, a miscommunicated coverage scope, or a missing tail can expose a clinician to personal liability for a claim that should have been covered. Understanding how coverage works — and asking the right questions before signing anything — is not optional. It's professional self-defense.
This guide covers the core concepts every locum clinician needs to know.
Claims-Made vs. Occurrence: The Foundational Distinction
Before anything else, you need to understand the two fundamental types of malpractice insurance policies:
Occurrence Policies
An occurrence policy covers any incident that occurred during the policy period, regardless of when the claim is filed. If you were covered on the date of the alleged incident, you're covered — even if the claim surfaces three years later and your policy has long since lapsed.
Occurrence coverage is the simpler model, and from a clinician's perspective, the more protective one. Once a policy period ends, you have no ongoing obligations. No tail required.
The catch: occurrence policies are more expensive, and they're increasingly rare. Most hospital credentialing departments and many staffing agencies have moved away from them.
Claims-Made Policies
A claims-made policy covers incidents only if both the alleged event and the claim filing occur while the policy is active. The moment the policy lapses — end of assignment, change in staffing agency, expiration — any future claim about an incident during that period is no longer covered.
This is the dominant model in locum tenens, and it creates a structural gap: the period between when a policy ends and when a resulting claim might be filed. That gap is where tail coverage comes in.
Tail Coverage: What It Is and Why It Matters
Tail coverage (formally, an "Extended Reporting Period" endorsement) extends a claims-made policy's reporting window after the policy itself ends. If you had coverage on the date of an incident but the claim arrives after your policy lapsed, tail coverage is what pays for your defense.
Without tail coverage, a clinician who was properly insured during an assignment can still face uncovered personal liability years later — when a patient files a claim tied to a procedure from a previous engagement.
Who Pays for the Tail?
This is where locum tenens gets complicated. Responsibility for tail coverage depends on who provided the underlying policy:
When the staffing agency provides coverage: Many agencies include tail coverage as part of their standard arrangement. Before assuming this, get it in writing. Ask specifically: does coverage extend to claims filed after the assignment ends, and for how long?
When the facility provides coverage: Some hospitals and health systems extend their institutional policies to cover locum clinicians. In this case, you're covered under their policy while you're on their premises — but once the relationship ends, the institution's tail (if any) may not cover you. Confirm explicitly.
When you carry your own policy: If you've purchased your own claims-made coverage independently — which some experienced locums prefer for continuity — you're responsible for purchasing tail coverage when that policy ends or when you switch carriers. Tail premiums are typically 150–200% of the annual premium for the expiring policy. It's a significant cost, but it's the cost of being properly covered.
Nose Coverage: The Less-Discussed Alternative
Tail coverage extends backward from a policy's end date. Nose coverage (a "prior acts" endorsement) works in the opposite direction — it extends forward from a new policy's start date to cover incidents that occurred before the new policy began.
If a clinician switches from one carrier or agency arrangement to another, and purchases nose coverage on the new policy, they can avoid a coverage gap without buying a separate tail. The two approaches are economically equivalent, but nose coverage is typically purchased by the incoming carrier rather than the departing one, and it's sometimes less expensive.
When starting with a new agency or facility, it's worth asking whether they offer prior acts coverage as part of their standard arrangement.
Common Coverage Gaps in Locum Tenens
The episodic nature of locum work creates several structural points where coverage can fall through:
Between Assignments
If you finish one engagement on a Friday and start another on Monday, there may be no active policy for those 72 hours. That matters if a patient from the previous assignment files a claim and you relied on claims-made coverage with no tail. Most gaps are shorter than they'd need to be to matter in practice — but "most" is not "all."
Agency Transitions
Switching from one staffing agency to another is one of the highest-risk moments for a coverage gap. Each agency typically carries its own policy. Unless you've confirmed tail coverage from the departing agency and prior acts coverage from the incoming one, there may be a window of exposure between the two policy periods.
Specialties and Procedures
Coverage scope matters as much as timing. A policy issued for emergency medicine may not automatically extend to a procedure you perform that falls outside your listed specialty. If you have dual board certifications or routinely perform procedures across specialty lines, verify explicitly that your malpractice coverage matches your actual scope of practice.
State-Specific Licensing and Coverage
Some states require clinicians to carry minimum coverage limits as a condition of licensure or hospital credentialing. If you're working across state lines — which is common in locum tenens — confirm that your policy's coverage territory and limits meet each state's requirements. If you're new to navigating multi-state licensing, the Locum Tenens 101 guide has a full breakdown of the licensing and credentialing process.
Questions to Ask Before Accepting an Assignment
Before signing any locum agreement, get clear answers to the following:
1. Who provides malpractice coverage for this engagement — the agency or the facility?
If both claim to provide coverage, confirm they don't overlap in a way that leaves neither fully responsible.
2. What type of policy is it — claims-made or occurrence?
If claims-made, ask who purchases tail coverage and for what reporting period.
3. What are the policy limits?
Standard minimums are $1 million per occurrence / $3 million aggregate, but high-acuity specialties or states with higher litigation rates may require more.
4. Does coverage extend to all procedures I perform, or only those listed in my primary specialty?
Get the answer in writing, especially if your practice includes any off-label or cross-specialty work.
5. Is there a gap period between this assignment and my previous one, and how is it handled?
If there's a gap, ask whether the agency can back-date coverage or whether you need to purchase separate tail coverage for the interim.
6. What happens if a claim is filed after this assignment ends?
The answer to this question defines whether you're actually protected.
Employer-Provided vs. Independent Coverage: A Practical Comparison
| Factor | Agency/Facility Policy | Your Own Policy |
|---|---|---|
| Cost to you | Usually zero | Premium out-of-pocket |
| Continuity | Resets with each engagement | Portable across assignments |
| Tail responsibility | Negotiated with agency | Your responsibility |
| Coverage customization | Limited | Flexible |
| Long-term simplicity | Requires per-assignment verification | One policy to track |
Most locum clinicians — especially those early in their careers — rely on agency-provided coverage and verify the terms before each engagement. That's a reasonable approach if you're diligent about documentation. For clinicians who work independently, carry multiple specialty privileges, or operate across many different agencies simultaneously, an independent policy with continuous tail coverage often makes more sense.
Documentation: The Piece Most Clinicians Skip
Whatever arrangement you have, document it. Request a certificate of insurance before each assignment begins. Keep copies of every policy declaration page, every confirmation of tail coverage, and every contract clause that addresses malpractice. If a claim arrives years after an engagement, this documentation is the difference between a covered defense and an uncovered one.
Malpractice claims in emergency and urgent care can surface 18–24 months after an incident. In obstetrics, the statute of limitations for minors may extend coverage obligations for years or decades. The documentation you maintain today is protecting against claims that haven't been filed yet.
How This Fits Into Your Broader Financial Picture
Malpractice coverage isn't just a compliance checkbox — it's a meaningful component of your total compensation structure. If an agency offers a higher hourly rate but passes tail costs to the clinician, the net economics may favor a lower-rate agency that absorbs tail. Clinicians who track these variables carefully often find that understanding the full structure of locum pay — hourly rate, benefits, housing, and insurance — matters more than the headline rate.
For clinicians preparing for their first assignment and working through the full logistics checklist, what to expect during your first locum assignment includes a practical walkthrough of how these arrangements typically get confirmed during onboarding.
The Bottom Line
Malpractice coverage in locum tenens is not something to assume, delegate, or defer. The fragmented nature of temporary work creates real structural gaps — and the consequences of falling into one are personal and potentially career-altering.
The framework is straightforward: understand whether your policy is claims-made or occurrence, know who holds tail coverage responsibility, verify the coverage scope matches your actual practice, and document everything. Ask the questions before you sign. The conversations feel tedious when everything goes well and essential when it doesn't.
