Malpractice Liability Costs And The Practice Of Medicine In The Medicare Program This analysis suggests that an important association exists between malpractice costs and the use of imaging services in particular.

Mounting malpractice liability costs might affect physician practice patterns in many ways, such as increasing the use of diagnostic procedures while reducing major sur- geries. This paper quantifies the association between malpractice liability costs and the use of physician services in Medicare. We find that higher malpractice awards and premi- ums are associated with higher Medicare spending, especially for imaging services that are often believed to be driven by physicians' fears of malpractice. The 60 percent increase in malpractice premiums between 2000 and 2003 is associated with an increase in total Medicare spending of more than $15 billion. (Health Affairs 26, no. 3 (2007): 841-852;
