Insurance Changes in Missouri

An interesting bill became law this week in Missouri.  In addition to some controls on rate increases, it has some information-gathering components:

makes self-financed malpractice insurers subject to state reporting requirements and directs the state insurance director to establish risk-reporting categories for each physician specialty.

Medical malpractice insurers will be required to report actual rates charged, including assessments for each risk-reporting category, and the department will publish annual reports reflecting median market rates.

Is this common?
