Why Did My Malpractice Premium Go Up This Year? 7 Reasons Carriers Raise Rates

Most malpractice premium increases come from book-level severity and reinsurance, not from a claim on your own file. The AMA's 2026 analysis of Medical Liability Monitor data shows a seventh straight year of rising medical professional liability premiums from 2019 through 2025. In 2025, 39.9% of reported premiums went up and only 3.1% went down.

A flat renewal is no longer the default outcome. MLM's 2025 Rate Survey put the average overall rate change at +1.9%, with 62% of reported physician rates held flat. If you are in the 39.9% that rose, the seven reasons below are the ones underwriters actually use. Venue, roster growth, specialty class, and loss history can stack a second, file-specific layer on top of the cycle.

The Cycle Is the Floor, Not the Full Story

2019 through 2025 is seven consecutive years of rising MPL premiums in the AMA/MLM series. Thirty-six states had at least one reported increase in 2025. Eighteen states saw at least half of reported premiums rise. Eleven states had at least one premium up 10% or more. Pennsylvania, Kentucky, Florida, Illinois, and New York posted 10%+ increases in both 2024 and 2025.

If the incumbent letter says the market, that may be accurate. It is not a reason to skip a second A-rated indication.

Seven Reasons Carriers Raise Rates

1. Verdict Size and Defense Cost, Not Only Claim Count

Carriers price the next check, not only how often a suit is filed. Expert fees, longer discovery, and verdict inflation can move a rate indication even when your county's filing count is unchanged. Severity is a book-level problem. It still prints as a percentage on your declarations page.

2. Reinsurance Behind the Primary Policy

Your insurer does not retain every dollar of risk. Reinsurance treaties renew on their own calendar. When reinsurers charge more for medical professional liability, primary carriers pass that through as rate, thinner credits, or tighter appetite. You will not see a reinsurance bill. You will see a higher mature premium or smaller claims-free credit.

3. County, Jury Climate, and Legal Rules

Underwriters price the courthouse. Pennsylvania's three-year climb and New York's 95.7% up-share in 2025 are venue stories as much as specialty stories. Miami-Dade 2025 manuals cited by the AMA put internal medicine at $59,736 and OB/GYN and general surgery at $243,988 at $1M/$3M. Los Angeles manuals for the same classes sit at $8,274, $41,775, and $49,804. Same work, different jury pool.

4. Loss Runs, Open Reserves, and How the File Is Told

An open claim, a late-reported incident, or paid indemnity on a closed file can reprice you even if the hallway version of the case was nothing. Underwriters read loss runs. A reserved claim that has not paid still sits on the experience. One physician's history can load a small group's shared entity rate.

5. Class Code and What You Actually Do

You added endoscopy, office-based surgery, cosmetics, pain procedures, or obstetrical call. If last year's schedule does not match this year's CPT mix, the class code moves. Dropping obstetrics can cut class. Adding deliveries can put a gynecologist into the OB cell. Underwriters rate the work, not the website bio.

6. Headcount, Hours, and Who Joined the Roster

A new partner, two NPs, a 0.8 FTE coded as 0.5, or a locums who became a W-2 employee all increase exposure. MLM's 2025 median NP premium was $2,576, a market marker, not your endorsement. Premium that went up 18% is sometimes four extra clinicians plus a market bump, billed as one number.

7. The Carrier's Own Book and Appetite

If the physician book lost money, your renewal is part of the repair. That can look like a straight rate increase, a deductible that used to be optional, or a non-renewal dressed as higher terms. Appetite withdrawal in a specialty or county forces you onto surplus lines or a more expensive admitted market.

What Is Actually Negotiable

Not every increase is a filing you must swallow. Credits that were never applied—claims-free, risk-management CME, part-time and FTE, new-to-practice step rates, group-size, and association memberships—appear only if someone asks and the application supports them.

Class and county coding can be corrected. Deductible and limit structure can trade premium for balance-sheet risk. Competing A-rated paper tests whether the market is your carrier's market. Clean prior-acts and tail sequencing prevents a coverage gap from being priced into the move.

A broker cannot repeal a statewide 10% filing. A broker can stop you from paying a 10% filing plus a 12% coding error plus two uncredited NPs.

Before You Bind the Renewal

Split the increase into pieces: rate change, exposure change, credit change. Ask for the mature rate if you are still stepping. Ask whether any location, specialty, or headcount change drove the delta. Then put the same application in front of other A-rated markets.

FAQ

Why did my malpractice insurance premium increase?

Most often because of book-level severity and reinsurance in a seven-year rising-premium cycle, sometimes compounded by venue, claims history, specialty reclass, or roster growth.

Is a 10% increase normal in 2026?

It is common in some states and unusual in others. Eleven states had at least one 10%+ increase in 2025. MLM's overall average change was +1.9%.

Could an unreported claim be sitting on my file?

Check the loss run. Open reserves and incident reports can reprice a small independent group even without a payout.

Can I shop after I already received a renewal?

Yes. A renewal indication is not a contract until you bind. Independent groups should compare 5+ A-rated insurers, especially after a double-digit increase or a county or specialty change.

Will changing carriers cut the premium?

Sometimes. A new carrier may credit a clean record differently, or may be hungrier in your class. Switching also raises prior-acts and tail questions. Price the whole move, not the first-year delta.
