Top medical professional liability insurers North America 2020-2022, by market share
Berkshire Hathaway is the clear market leader
Berkshire Hathaway Group wrote direct medical professional liability insurance premiums worth over two billion U.S. dollars in 2022. Doctors Co Group and Proassurance Corp Group were the second and third largest medical malpractice insurers, respectively, but their combined direct premiums equaled less than those written by Berkshire. This indicates that Berkshire is likely to remain the market leader in the near future, unless another company dramatically increases their medical malpractice insurance operations.
