The same specialty can cost 10x more depending on the state
The same specialty, doing the same work, can cost eight to fourteen times more depending on the state. The filed rates behind the swing, and what drives it.
A general surgeon in Wisconsin has a filed malpractice rate of about $11,286 a year. The same general surgeon, doing the same operations, is filed at about $118,410 in New Mexico. That is roughly 10.5 times the premium for identical work, and the only thing that changed is the state line.
This is the most striking pattern in the filed data. Not that surgeons pay more than psychiatrists, which everyone expects, but that a single specialty swings tenfold or more across the map. Geography, not medicine, sets the range.
- General surgery — 10.5x · $11,286 in Wisconsin to $118,410 in New Mexico
- Widest spread — 15.1x · Pediatrics, Wisconsin to West Virginia
- OB/GYN dollars — $136k · The annual gap for one physician
- Low anchor — WI · Cheapest state for nearly every specialty
Every figure here comes from carrier rate filings on record with state insurance departments (the SERFF system and state DOIs), normalized to one basis so the numbers compare cleanly: $1M/$3M limits, mature claims-made, manual rate. These are filed rates, not survey ranges.
The finding: identical specialty, wildly different price
Take any high-volume specialty, find its cheapest state and its most expensive, and the gap is enormous. Here are five, each showing the lowest and highest filed state rate and the multiple between them:
The pattern is not limited to surgeons. Psychiatry, the cheapest specialty nationally, still swings from about $1,630 in Wisconsin to about $23,225 in West Virginia, a spread of roughly 14 times. Internal medicine runs from about $3,010 to about $31,396. Whatever you practice, the state you practice in can move your premium by an order of magnitude.
One consistency worth noticing: Wisconsin anchors the low end for nearly every specialty. That is not a coincidence, and we come back to why below.
The swing is large in percentage terms and larger still in dollars. For OB/GYN it runs from about $18,456 to about $154,590, a difference of roughly $136,000 a year for the same physician. General surgery swings about $107,000 from Wisconsin to New Mexico. Even mid-tier specialties move by tens of thousands. That is real money on the profit-and-loss of a practice, and it is why coverage cost belongs in any decision about where to work, not just the salary.
General surgery: about $11k in Wisconsin, about $118k in New Mexico
General surgery is the clean example because the specialty is broadly comparable across states. The filed rate in Wisconsin is about $11,286 a year at the mature claims-made basis. In New Mexico it is about $118,410. A surgeon who relocates without changing anything about their practice can see their coverage cost multiply by more than ten.
A caution on the extremes, because this post invites scrutiny. The single highest and lowest cells often rest on one filed carrier, which makes the exact multiple indicative rather than precise. The New Mexico and Wisconsin general-surgery figures each come from a single carrier's filing. The direction and the rough magnitude are solid; the last dollar is not. The steadier version of the same finding is the state-median ranking, which pools all 19 specialties per state and still shows the most expensive state at about 9.6 times the cheapest.
Emergency medicine: about $6k to about $64k
Emergency medicine tells the same story at a lower absolute level. The filed rate runs from about $6,270 in Wisconsin to about $64,054 in New Jersey, roughly 10.2 times. Emergency physicians are often employed or contracted rather than buying their own policy, so this is frequently the group's or staffing company's cost rather than the individual's, but the geographic swing is identical in shape. The work is the same in Milwaukee and Newark. The price is not.
Why the same work costs 10x more
The driver is the legal and structural environment around a claim, not the clinical work. A few forces stack up.
The tort and verdict environment sets carrier expectations. In states where large jury awards are common, carriers price for that severity, and it flows straight into the manual rate. Damage caps push the other way: a state that limits noneconomic damages gives carriers a more predictable ceiling, which tends to lower premiums. Wisconsin, the low anchor across specialties, pairs a noneconomic cap with a state patient compensation fund that backstops large claims, which is a large part of why it sits at the bottom for almost everything.
The work is the same in Milwaukee and Newark. The price is not.
Carrier competition matters too. A state with many carriers actively writing a specialty has price competition; a state with one or two does not. That shows up both in the price and in the data itself, since several of the extreme cells rest on a single filed carrier. Territory within a state adds another layer: a metro county with a heavy claims history can be filed well above the state median, so the in-state range is real on top of the state-to-state range.

What a physician or broker does with this
For a physician, the practical takeaways are two. First, a quote is only meaningful against your own state and specialty, never a national average, because the national average blends a $6,000 market and a $64,000 market into a number nobody pays. Second, if you are weighing a move, coverage cost belongs in the math: a $100,000 swing in malpractice premium changes the economics of a job in a way that a salary comparison alone will miss.
For a broker, this spread is the whole pitch. A client who assumes their high number is just "what malpractice costs" is often comparing against the wrong baseline. The filed benchmark shows where the state-and-specialty median actually sits, and a broker who works that market can take the number to the carriers competing there now and come back with options. Start from the filed benchmark for your state and specialty, then let a broker shop it.

Common questions
Why does malpractice insurance cost so much more in some states?
The legal and structural environment: the local tort and verdict climate, whether the state caps noneconomic damages, whether it runs a patient compensation fund, and how many carriers compete there. The medicine is the same; the claim environment is not.
How much can the same specialty vary by state?
By roughly 8 to 14 times across the specialties we track. General surgery runs about 10.5 times from cheapest to most expensive state, emergency medicine about 10.2 times, orthopedic surgery about 12 times, all on the same $1M/$3M mature claims-made basis.
Which state is cheapest for malpractice insurance?
Wisconsin anchors the low end for nearly every specialty, helped by a noneconomic damage cap and a state patient compensation fund.
Sources and method
- What we computed — For each specialty, the lowest and highest state filed rate and the multiple between them
- Basis — $1M/$3M limits, mature claims-made, manual (pre-credit) rate, from carrier rate filings (SERFF and state DOIs); occurrence filings are converted to a claims-made-equivalent mature rate
- Coverage — 51 jurisdictions, 19 specialties, 969 cells, from 1,739 filed carrier rates
- Extreme cells — The min and max cells for a specialty frequently rest on a single filed carrier, including New Mexico and Wisconsin general surgery, New Jersey and Wisconsin emergency medicine, West Virginia orthopedics and anesthesiology, and Connecticut OB/GYN
- How to read it — Multiples are indicative of magnitude and direction, not precise to the dollar; the state-median ranking pools 19 cells per state and shows a 9.6x top-to-bottom spread
