Let me tell you what really happens when you switch locum agencies and think your malpractice follows you. It doesn't.
I've sat in credentialing offices while a locums doc - good clinician, clean record - gets a letter from a lawyer. Two years after he left an assignment in Arizona. Patient sued. He called his old agency. "Oh, that policy ended when you left." No tail. No coverage. Just him, alone, staring at a $75k retainer for a defense attorney.
This happens more than anyone wants to admit. Locum agencies love to say "you're fully covered." They are. Until you leave.
This information is for educational purposes only and is not financial advice, not legal advice, and not tax advice. Tail costs and coverage terms change constantly and figures vary by carrier and state, so consult a qualified professional before you make any decisions about your policy.
The Dirty Little Secret: Tail Coverage Doesn't Follow You
Here's the truth program directors and recruiters gloss over. Almost every locum agency buys you a claims-made policy.
Claims-made means you are covered ONLY if two things are true at the same time: the incident happened while the policy was active, AND the claim is reported while the policy is active. The second part is the killer.
When you quit Agency A and jump to Agency B, Agency A's policy terminates. Instantly. That policy is dead. If a patient from your time at Agency A files suit six months later - which is exactly how malpractice works, slow and delayed - you have no active policy to report it to. No report, no coverage.
You have to buy tail coverage separately from that previous carrier. Tail - properly called an Extended Reporting Period - keeps the reporting window open after the policy dies. Without it, you are naked.
And nobody tells you. Your carrier won't. Why would they? The carrier works for the agency that pays the premium, not for you. The agency's risk manager isn't incentivized to explain portability. They want you signed, staffed, and moved. I have reviewed agency contracts where tail is mentioned in one throwaway sentence on page 14. No explanation. No cost estimate.
You discover the gap too late. Usually when you get the certified letter. By then your 30-day window to buy tail has closed.
That gap is not a technicality. It is a career-ending trap.
How Switching Agencies Creates a Coverage Gap
Picture this. You're at Agency A for eight months. Good gig. You see patients, you do procedures, you chart. One case - maybe a missed PE, maybe a surgical complication - doesn't declare itself as a lawsuit until much later. That is normal.
Then you get a better rate at Agency B. You switch. Clean break. New certificate of insurance lands in your inbox. You think you're good.
You're not. You just created a gap.
Here is the exact flow. It is brutally simple and 100% preventable if someone had explained it to you day one.
Three details carriers conveniently forget to mention in that flow:
First, that tail purchase window. Most policies give you 30 to 60 days after cancellation to elect and pay for tail. Not 30 days after you get sued. 30 days after you leave. Some policies are even tighter - 14 days if you read the fine print. Miss it and you can never buy it for that period. Ever. You are permanently exposed.
Second, even if you buy tail, delayed reporting can still void you. I've seen carriers deny because the physician "should have known" about a potential claim earlier and didn't give notice. You had a bad outcome, you charted it, but you didn't file an incident report with the old carrier. They call that late notice. Denied.
Third, pre-existing conditions. If you had an incident that was already brewing - say a patient complained, or risk management emailed you before you left - and you didn't disclose it when buying tail, some carriers will exclude that specific case. You paid for tail and still aren't covered for the one claim that matters.
Switching agencies without a written tail plan is like jumping between cliffs and hoping you grow wings on the way down. locums docs do it constantly because no one shows them the gap until they're falling.
The Real Cost of Tail Coverage: What Carriers Don't Quote
You want to know why carriers don't disclose tail costs up front? Because if they did, you'd negotiate harder.
Tail is not cheap. It is not 10% extra. The industry standard is 150% to 220% of your annual premium - due as a single lump sum within 30 days of leaving. Not monthly. Lump sum.
For a low-risk specialty like pediatrics or internal medicine, you might see 1.3 to 1.5x. For general surgery, EM, 1.6 to 1.8x. For OB/GYN, neurosurgery, orthopedics - the high-risk worlds - 2.2x is common. I've seen OB tails quoted at more than double the yearly premium.
That's just the multiple. The actual premium itself varies wildly. State matters - California, New York, Florida cost more. Claims history matters - even a closed claim with no payout raises your tail. How long you were covered matters.
And here's the part that shocks people: the invoice arrives AFTER you have already left. You've got your last paycheck, maybe you're between assignments, and then - boom - a $30k, $50k, sometimes $80k bill with a net-30.
You can't finance it through the carrier. You can't roll it into your new agency's policy. You have to pay it.
Agencies know this number freezes doctors. So they don't bring it up during recruitment. They say "malpractice included." Technically true. Practically misleading. Because what's included is the claims-made policy, not the tail you need to make that policy useful after you walk away.
Ask for the tail cost in writing on day one. If they won't give it to you, that tells you everything.
What Your Locum Contract Should Say About Tail Coverage
Never - and I mean never - sign a claims-made policy without a tail clause you can live with. Verbal promises are worthless. "Oh we always take care of our docs" is worthless.
You have three acceptable options, and only three:
One, occurrence-based coverage. Occurrence covers you forever for any incident that happened during the policy period, even if reported years later. No tail needed. Pure gold. Agencies rarely offer it because it costs them about 30% more. If you can get occurrence, take it. Stop reading.
Two, claims-made with tail included, paid by the agency. This should be written as "Agency shall provide and pay for unlimited or minimum 2-year extended reporting tail upon termination for any reason." Note the words: provide and pay for. And "any reason" - because some shady contracts only cover tail if THEY terminate you, not if you quit.
Three, claims-made with a tail cost cap and a guaranteed right to buy. If they won't pay for it, at least get language like "Physician shall have the option to purchase tail at no more than 175% of annual premium, Agency to provide written quote within 10 days of termination."
What I tell every locums doc: before you sign, send this email. Copy it.
"Please confirm in writing: policy type (occurrence or claims-made), who pays for tail upon separation, cost cap if I pay, and the window to elect tail."
If they hesitate, push back, or say "don't worry about it, we handle it" - walk. Plenty of agencies will put it in writing. The good ones actually advertise "tail included" because they know it matters.
I have seen physicians get tail added just by asking. Recruiters have a budget for this. They won't offer unless you ask. So ask. Every single time.
Nose Coverage: The Hidden Safety Net
Tail looks backward from your old policy. Nose - prior acts coverage - looks backward from your new policy. Same result, different payer.
Here's how it works. When you start at Agency B with a new claims-made policy, that policy normally only covers incidents that happen AFTER the start date. Nose coverage extends its retroactive date backward, to cover your prior work at Agency A.
Effectively, Agency B's new policy agrees to cover old incidents that haven't been reported yet. If done correctly, it can replace the need for tail from Agency A.
And it's often cheaper. Because Agency B is already buying you a policy - adding prior acts is incremental, not a full new premium. Sometimes 20-40% cheaper than a standalone tail.
Agencies rarely offer it. Why? Two reasons. One, it increases their risk. Two, most recruiters don't even know what it is. They've never had to sell it.
You have to negotiate it. Say: "Instead of me buying tail from my prior carrier, will your carrier provide prior acts coverage with retro date of [last assignment start date]?"
Get the retro date in writing on the certificate. Not "prior acts included" - that's vague. You need "Retroactive Date: 08/01/2024" or whatever your actual start was at the old agency.
Nose doesn't work in every state or with every carrier, and it won't cover you if you already bought tail - you can't double dip. But when you're switching agencies fast, it is the smartest financial move most locums docs never hear about until I've told them.
Reflection: Protect Your Future Self
The malpractice system is slow. Patient care is fast. That mismatch is where docs get hurt.
Tail coverage is boring paperwork. Until it isn't. Until it's a lawsuit in year three from a shift you barely remember, and you're on the hook because you saved $50k by not buying tail.
Your carrier will not protect you. Your agency will not protect you unless you make them. The system is set up to assume you'll forget, you'll be too busy, you'll trust.
Don't.
Five minutes of hard conversation before you sign - policy type, who pays tail, nose option - saves you tens of thousands and potentially your license and savings. Be the annoying doctor who asks about fine print. That annoying doctor is the one who still has coverage when the letter arrives.
