The National Association of Insurance Commissioners announced Thursday it has voted to adopt a model regulation containing the definitions and methodologies for calculating medical loss ratios as required by health reform.

The vote by the association's Executive and Plenary Committees is a final move before the MLR model is passed onto Health and Human Services Secretary Kathleen Sebelius for certification.

"I commend the work of our regulators and staff as we considered a number of very challenging issues as it moved through the committee process. The committee model regulation on MLR passed with only technical amendments, which is a testament to our inclusive and transparent process," said Jane L. Cline, NAIC president and West Virginia insurance commissioner, in a statement. "It is with a great deal of pride we present these recommendations to the Secretary."
