MI SB1359

Modifies the health insurance claims assessment rate structure for dates of service beginning January 1, 2012, removing the flat 1% rate and replacing it with a variable rate system.

Sets assessment rates at 1% for 2012, then allows rates in 2013-2014 to be adjusted by the Department of Treasury based on whether prior year revenue matched the "base need" of $400,000,000 (adjusted annually by medical inflation).

Reduces assessment to 0.1% for carriers with suspensions or exemptions under the Insurance Code of 1956.

Caps total assessment liability at $10,000 per insured individual or covered life annually and clarifies responsibility for assessments among carriers, third-party administrators, and excess loss/stop loss insurers.

Removes provisions allowing carriers and third-party administrators to receive proportional credits or refunds if assessments exceed the base need amount.
