Tenesma,
MechE and UNEOSTEO were pretty close. Perhaps you should check your sources a little better. Here's what I found in about 45 seconds:
"This spring the ASA Committee on Professional Liability again conducted a survey of 46 medical liability insurance carriers to assess rate changes and market trends in 2004. We compared 2004 premiums to similar surveys in 2002 and 2003.4,5 The average premium for anesthesiologists in 2004 was $20,611 (range = $3,958 to $62,400) compared to $15,476 (range = $4,855 to $58,089) in 2002, representing a 33-percent increase [Figure 1]. The premiums are highly variable, however, with markedly high premiums for anesthesiologists with prior history of a lawsuit, performance of higher-risk procedures (e.g., invasive pain management, office-based surgery), and for those practicing in localities with high liability risk. Mean premiums were fairly similar in 2003 and 2004, although some states experienced increases of more than 40 percent (Alabama, Colorado, Maryland, Missouri, New Hampshire and Oklahoma). In 2002, five states had average premiums of greater than $20,000, while 22 states had average premiums of more than $20,000 in 2004. The highest average premiums (>$30,000) during 2004 were found in Florida, Illinois, Michigan, Ohio and West Virginia, with premiums in Florida leading the nation. Rate increases have been particularly severe when insurance carriers have withdrawn from the market in the state."
