Tail Coverage for Locums CRNAs: What It Is and Who Should Be Paying for It
Most CRNAs understand malpractice insurance in the context of a staff job, where the employer handles it and you never think about it. Going locums changes that. The type of policy covering you, and what happens to that coverage when a contract ends, is now your problem to understand before you sign anything.
Why This Matters More in Locums
In a staff position, malpractice claims typically follow the employer's policy. You're covered, continuity is maintained year to year, and when you leave the organization there's usually a transition process that accounts for outstanding exposure. You don't manage any of it yourself.
In locums, you're moving between facilities and contracts. Each contract may carry different insurance arrangements. And unlike a W-2 job, when a locums contract ends, your coverage doesn't automatically continue. Depending on the type of policy, the moment the contract expires, you may have no protection against claims that haven't been filed yet, even for incidents that occurred while you were actively working and covered.
That's where tail coverage comes in.
The Two Types of Malpractice Policies
Before tail coverage makes sense, you need to understand the difference between the two types of malpractice policies. This distinction determines whether you need tail at all.
Occurrence-Based
- Covers any incident that occurred during the policy period
- Claims can be filed years later and still be covered
- Coverage follows the incident, not the policy status
- No tail coverage needed when the policy ends
- Generally costs more upfront
Claims-Made
- Covers claims filed while the policy is active
- If the policy lapses and a claim is filed, you are not covered
- Coverage follows the policy status, not the incident
- Tail coverage required when the policy ends
- Generally costs less upfront
Most locums contracts use claims-made policies because they're less expensive for the agency or facility to carry. That lower upfront cost shifts risk to you at the end of the contract, because when that policy expires, your protection against future claims for past incidents expires with it.
What Tail Coverage Actually Does
Tail coverage, formally called an Extended Reporting Period endorsement, extends the reporting window on a claims-made policy after it ends. If you worked at a facility for 13 weeks under a claims-made policy, and six months later a patient files a claim related to a case you did in week four, tail coverage is what allows that claim to be reported under the original policy.
Without tail coverage in that scenario, you have no defense. The policy is expired. The claim gets filed against you personally. If you don't have separate coverage in place, you're paying for legal defense and any settlement out of pocket.
Malpractice claims in anesthesia often surface months to years after an incident, not days. A patient who had an awareness event, a nerve injury, or a postoperative complication may not file a claim until well after your contract has ended. Claims-made policies without tail coverage leave you exposed to exactly this scenario.
What Tail Coverage Costs
Tail coverage is typically priced as a percentage of your annual claims-made premium, and the percentage depends on how many years of extended reporting you're purchasing. A one-year tail costs less than a three-year tail, and a permanent tail costs the most.
| Coverage Duration | Typical Cost (CRNAs) | Notes |
|---|---|---|
| 1-year tail | $1,500 to $3,500 | Minimum for short assignments |
| 3-year tail | $4,000 to $8,000 | Common standard for most contracts |
| 5-year tail | $6,000 to $12,000 | Recommended for OB or complex cases |
| Permanent tail | $10,000 to $20,000 | Full protection, no future exposure |
The exact cost varies depending on your specialty, the carrier, your claims history, and the specific terms of the original policy. OB anesthesia and complex cardiac cases typically push premiums toward the higher end because the statute of limitations on related claims can extend further.
Who Pays for Tail Coverage
This is the question that most directly affects your wallet, and the answer depends entirely on what your contract says.
In many locums arrangements, the agency or facility covers malpractice and tail as part of the contract. But "covered" can mean different things. Some agencies provide occurrence-based coverage, which requires no tail at all. Others provide claims-made coverage and include tail in the package. Others provide claims-made coverage and leave tail entirely to you, sometimes without making that clear in plain language.
Find the malpractice section and look for two things. First, whether the policy is occurrence-based or claims-made. Second, if it's claims-made, who is responsible for tail coverage and for how long. If the contract says malpractice is provided but doesn't specify the policy type or tail responsibility, ask before you sign. The answer matters.
When you should expect the agency to cover tail
If the agency or facility is providing malpractice insurance as part of the contract, tail coverage should follow. This is especially true if the contract termination is initiated by the agency or facility, if you complete the full contract term as agreed, or if the agency is a larger organization running a locums program at scale. In these situations, pushing back on tail coverage is reasonable and often successful.
When you may end up paying for it yourself
If you terminate a contract early, some agreements shift tail responsibility to you. If you're sourcing contracts independently rather than through an agency, the facility may not offer coverage at all. And if the contract language is vague and you didn't ask before signing, you may find out the hard way that tail was never included.
Some CRNAs who do significant locums volume purchase their own occurrence-based policy rather than relying on contract-by-contract claims-made coverage. It costs more upfront but eliminates the tail question entirely. If you're planning to do locums consistently across multiple agencies and facilities over several years, this is worth pricing out with a healthcare malpractice broker.
The Questions to Ask Before You Sign
You don't need to be a malpractice expert to protect yourself. You just need to ask four specific questions before accepting any locums contract:
- Is the malpractice coverage occurrence-based or claims-made? If occurrence-based, you're done. If claims-made, keep going.
- Who is responsible for tail coverage when the contract ends? Get the answer in writing, not from a recruiter verbally.
- How many years of tail coverage are provided? Three years is a reasonable minimum for most CRNA work. Five is better for OB.
- What happens to tail coverage if I terminate early or the facility terminates me? Some contracts shift responsibility based on who ends the agreement.
If the contract is silent on any of these and the recruiter can't get you a written answer, that's a problem worth taking seriously before you sign.
The Bottom Line
Tail coverage is not a technicality. For CRNAs doing locums on claims-made policies, it's the difference between being protected and being personally liable for claims filed after a contract ends. The cost is real and ranges from a few thousand dollars to over $20,000 for permanent coverage. Who pays for it should be clearly spelled out in your contract before you ever set foot in that facility.
Check the policy type. Confirm tail responsibility in writing. If the contract doesn't address it clearly, ask before you sign. This is one of those details that's easy to overlook when the rate looks good and you're ready to commit, and expensive to deal with after the fact.
